Mexican textile picked up market share in the United States

Mexican Textile Export to America is Great

Since the exports gradually focus on higher value-added and diversified products, Mexican textile and apparel products have a gradual recovery in the U.S. market share. According to the U.S. Department of Commerce Textile and Clothing Bureau (OTEXA) data that, in 2011, Mexican exports to the U.S. apparel amounted to $ 3.8 billion, an increase of 7.4%. The United States accounted for the proportion of Mexico's textile and garment export market by 55% and 95% respectively, but since 2001, Mexico's share in the global textile and apparel market is gradually decreasing. In 2000, Mexico's largest supplier of U.S. imports is clothing, but by the end of 2010, it had fallen to the sixth place. Andreu, a professional adviser who has many cooperation relations with many Mexican jacquard fabrics and garment manufacturers said that, the Mexican industry has gradually managed to play to its advantages, especially in the low cost and open up the U.S. market. When U.S. buyers do not want a large number of orders for procurement clothing due to the U.S. market continues to be unstable, and, as Mexico Garment Association Canaive shows that, overall manufacturing wage gap between Mexico and Southeast Asian countries in recent years has significantly reduced.

Diversification of Denim Fabric Product

One of the most important things for the recovery of Mexico's garment industry is the improvement of Mexican denim fabric product quality upgrading and diversification. Today, there are more and more garment manufacturers shift production to popular products and profit due to get rid of the bulk stuff orders, many garment factories pick a short delivery orders and put into the production of high-quality design products, such as many suit factory product line has been extended toward the popular clothing market. In addition, the Mexican garment factories and cooperative relations with the United States brands are also increasingly closely to meet the specific needs of garment factories in Mexico, and especially denim apparel production industry, manufacturers provide full manufacturing services is also increasing. Jeans are mostly higher priced garment factory production and innovative material.

Functional Denim Fabrics

Mexican fabric manufacturers now many supply higher priced functional fabrics as the mainstream. They aim to promote the exports institution Mexico Fits by multiple units including the Mexican Clothing Association Canaive, the Mexican Textile Association Canaintex, Mexican Chemical Industry Association ANIQ Mexican Ministry of Economy and ProMexico. The agency pointed out that Mexico's production of garments number of items is increasing, in addition to jeans and T-shirts, including woven, knit shirts, denim cotton trousers, dresses, suits, underwear, hosiery, sportswear, swimwear and knitted garments.

How Does Cerium Oxide Polishing Powder Work?

Components and features of cerium oxide polishing powder

The main ingredient of the cerium oxide polishing powder is cerium dioxide (CeO2), followed by lanthanum oxide (La2O3), praseodymium oxide (Pr2O3), also containing a trace amount of silicon oxide, aluminum oxide and calcium oxide. cerium oxide powder is widely used in glass polishing, which has strong cutting, short polishing time, long life, high precision polishing advantages. According to the content of the cerium oxide, cerium oxide polishing powder is divided into low cerium, medium cerium, high cerium polishing powder, their cutting forces and service life are from low to high.

Cerium oxide polishing powder effects in the polishing process

Cerium oxide polishing glass is a chemical-mechanical process. Cerium oxide polishing powder has two effects in the polishing process, namely mechanical action, and colloid chemistry, these two effects occur simultaneously. The initial stage of the polishing is the process for CeO2 to remove surface irregularities layer, and thus showing a new polished surface, the mechanical action is a major at this time. Meanwhile, since there is water in the polishing mixture, H3O ions are formed in the polishing process, H3O ion and Na ion mutually exchange in the glass surface and form hydrolysis compound with the glass; Furthermore, since CeO2 polishing agent has a polyvalent nature, the oxidation-reduction reaction of Ce (3) / Ce (5) will destroy the silicate crystal lattice, and oxidized the contact material from the glass surface with polishing agent, and forming a complex to be removed by chemical adsorption (including glass and hydrolyzing compound).

There are several theories on the interpretation of the cerium oxide polishing mechanism:

1. Chemical theory, the polishing process is a result of the chemical interaction among water, the polishing agent, polish mold material and glass.
2. Purely mechanical action doctrine, polishing is the continuance of grinding process.
3. Rheology doctrine, i.e. Friction heat makes the glass surface to produce the plastic deformation and flow, or heat-softened resulting in melting flow, the polishing process is the process the molecules on glass surface re-distributed and form a flat surface;
4. Mechanical, physical and chemical theory, the polishing process is a mechanical, physical and chemical effects process.

Experts believe that polishing is a mechanical, physical, chemical synthesis, wherein the mechanical action is basic, and the chemical action is important, while the rheology phenomenon exists. The reason why the cerium oxide is extremely effective polishing compound is because it can simultaneously polish glass with chemical decomposition and mechanical friction two forms. In the polishing process, cerium oxide producer has two effects, namely mechanical action and colloid chemistry action, these two effects occur simultaneously.

Basic Information of BOPP Film

Biaxially Oriented Polypropylene (BOPP) is a polypropylene film that has been stretched in both the machine and cross directions. BOPP film production from bopp film manufacturer: put the melt of polypropylene through the narrow head and make into a sheet or a thick film, and then in a dedicated stretching machine under a certain temperature and speed stretch in perpendicular directions (longitudinal and transverse) simultaneously or step-by-step, and after appropriate cooling or heat treatment or a special processing (such as corona, coating, etc.), here comes the thin film. Common BOPP films include common type of biaxially oriented polypropylene film, the heat sealing biaxially oriented polypropylene film, cigarette packaging film, BOPP pearlized film, metallized biaxially oriented polypropylene film, matt film and so on. BOPP film has become one of the most popular, high growth films in the world, such as anti-fog film.

Advantages of BOPP film:

- Excellent clarity
- Good dimensional stability and flatness
- Low electrostatic charge
- Good barrier to water vapor
- High gloss
- Good performance on high speed printing
- Resistant to oils and greases
- Good puncture and flex-crack resistance over a wide range of temperatures
- Not affected by moisture and does not wrinkle or shrink with environmental changes
- Recyclable

Disadvantages

BOPP film has disadvantages, such as easy to be static, without heat sealing. In high-speed operation of the production line, BOPP film is easy to produce static. And you need to install the electrostatic remover. In order to obtain a heat-sealable BOPP film, it can be coated after corona treatment on the surface with the heat-sealable resin glue, such as PVDC latex, EVA latex, etc.; and it can also be coated with a solvent adhesive and applied extrusion coating or the method of production of co-extruded composite heat sealable BOPP film. The film is widely used in the packaging of the bread, clothes, footwear, as well as the packaging of cigarettes, books cover. BOPP film initiator tear strength after stretching improved, but the the secondary tear strength was low, therefore, BOPP films both ends can not leave any incision or it will be easily torn during printing or composition. BOPP coated stickers can produce sealing tape which is the most common market of BOPP.

www.bopp-film.net Guangdong Decro Film New Materials Co., Ltd. and its sub-company Guangdong Decro Package Films Co., Ltd., combine to provide more than 20 years of BOPP production, providing its customer the most advanced range of BOPP products in the WORLD today. DECRO currently operates 8 BRUCKNER / MITSUIBISHI / JSW BOPP production lines in its two manufacturing plants in Guangdong Province in Southern China, contributing an annual output in excess of 130,000 tons of BOPP films.

Methods to Remove Stainless Steel Fasteners Surface Oxide Layer

Three ways to remove oxide layer on stainless steel fastener surface

Some stainless steel fasteners, after the series of processing, such as welding or annealing, will generate oxide layer on its surface, which will impact the Stainless Steel Fastenersquality. So we must remove the oxide layer. Typically, there are three removal ways, the impregnation method, the salt bath method, as well as salt membrane; they have their own characteristics, which should be chosen according to different situations.

1. Impregnation method

(1) Sulfuric acid - hydrochloric acid and sulfuric acid - nitric acid lotion

The acid lotion corrosion for the stainless steel fasteners substrate is relatively slow, there are much residue left on the surface of the fastener after dipping; dissolution for austenitic stainless steel fasteners is weaker, mainly used for Martensite stainless steel oxide impregnation.

(2) Nitric acid - hydrochloric acid pickling

The pickling has strong dissolvent ability for stainless steel fasteners oxide, fasteners surface is relatively clean after erosion, but the erosion on stainless steel fixings matrix is large, it is easy to cause corrosion if not controlled properly.

(3) Nitric acid - hydrofluoric acid pickling

The pickling has dissolution ability for stainless steel oxide surface, but dissolution for stainless steel fasteners matrix is weak, surface erosion is of good quality, but hydrofluoric acid is toxic, and it needs good ventilation and wastewater treatment conditions.

(4) Nitric acid - hydrofluoric acid - hydrochloric acid (or sulfuric acid) type pickling

The pickling has similar advantages with nitric acid - hydrofluoric acid lotion, fast response, wide scope of work.

2. Salt bath method

Salt treatment is also essentially pretreatment process, it uses different thermal expansion coefficients of the matrix metal and the oxide scale, make the oxidation skin crack by quenching, while enabling cheap oxide present in the outer layer of oxide turn into the acid-soluble higher oxides in strong role of the oxidizing agent, the loose film effect is better than alkaline sodium nitrite solution, but need to use special processing tank, the operating environment is also poor.

Salt bath composition and process: sodium hydroxide 87%; sodium nitrate 13%; temperature is 45-47 °C, operating time: 10min for Martensitic stainless steel fasteners and 20min for austenitic stainless steel fasteners; immediately quench when the fasteners come out of the slot. Treatment effect of the salt bath method is better, but there are some inadequacies. First, salt bath is solid at room temperature, preheating process is energy-intensive, time-consuming is too large; Second, fasteners bring more molten salt when out of the tank, which is a waste and pollutes the environment; Third, harsh operating environment. Therefore, now salt membrane is taken instead of salt-bath method to operate.

Four Development Stages of CPU Cooler

The first stage of its infancy

CPU cooler was born in 486 times, and at that time, the cooler was only a thin aluminum heatsink with the diameter of 4cm, and without a fan. Thin aluminum heat sink takes the use of the simplest aluminum extrusion process;

The second stages phase of the development

The CPU cooler has been widely used, while most of which are made of aluminum products, but there are a few copper coolers. And the cooler of this period has generally begun to use the fan, and thus brings the noise problem. Since then CPU heat is not large, so the very ordinary quiet cpu cooler will be able to meet the cooling needs. Fortunately, the generally cheap fan uses the very common industrial oil bearing, and the initial presentation of the use of oil bearing is in the good condition. However, with the growing of use time, dust absorption increased, and oil will evaporate due to the frictional heating, the fuel is gradually reduced, and the bearing friction and vibration are also increasing, resulting in increased bearing noise, increased wear and shortened the life expectancy;

The third growth stage

With the rising of CPU frequency and the scale of integrated transistor, the CPU temperature also grew exponentially and those cheap coolers in the past has far cannot meet the needs of the CPU cooling, while the demand for high efficient radiator is gradually put on the agenda. At this point, Japan, Europe and the United States, China's Taiwan Province, and South Korea and other countries and regions with precision machining and advanced electronics manufacturing processes, are beginning to adopt some new technology to manufacture radiators to meet the demand of the market. And this trend leads to two development booms: the first one is the bearing technology of the fan, and the other is the process technology of extruded heat sink.

The fourth stage of maturity

The appearance of P4E procured the maturity of the design and process tends of cooler, and the full copper heat cooler began to be spread by the virtue of the high heat transfer efficiency and moderate price, and becomes the mainstream product. Due to the large-scale production of full copper and heat pipe, the price is also quietly dropped and it is only slightly more expensive than pure copper, which is easily accepted by consumers. Pure copper and heat pipe radiator and water-cooled radiator also began to appear, its excellent cooling effect is impeccable, but the high price is also difficult to be accepted by the ordinary consumer.

www.heatsinkvet.com has a number of assembly lines and specialized manufacturing equipment. Its productive technologies include the following entire production and processed progress: Cutting off, cutting groove, stamping, drilling, tapping, CNC, relieving teeth, drawing bench, polishing, sandblasting, anode, assembly, etc.

Tips for the Use of Heat Pump Water Heater

Three reasons for the low efficiency of the heater

First, check whether the voltage in the range of unit rated run, if the voltage is no problem, just view compressor is functioning properly excluded the fan idling caused the illusion of unit operation. Next, reconfirm whether the water consumption match with the unit oif commercial heat pump water heater. Further check whether the control system sensors are in the good condition and make further exclusion.

Second, as the temperature is too low, the unit will not work, which cannot start. When the temperature is below 0 ° C, the air source heat pump water heater will enter the shutdown state, and when the temperature rises, the unit still cannot start properly, or rotating fans, but the compressor does not work.

Third, the work of unit is controlled by the controller, such as crew has worked for long hours, but did not reach down parameters set by the system, or the probe temperature is below the set range of values when the unit open work. Troubleshooting a refrigerant portable low thermal capacity and high set temperature, and then the temperature sensor failure or sensor short circuit, open circuit may cause the unit to shut down. Generally, the reason that leads to the long work hours of the air source low temperature heat pumpswater heater is the unreasonable ratio of the unit. For example, if the water of the unit is three tons, and the longest working hours of the design is 18 hours.

Solutions for the low efficiency of heat pump heater

First, check whether the compressor is damaged, and check the compressor resistance with multimeter, and focus on the examination of the control system. theHen the control unit factory description or engineering system design and inspection reports, based on the analysis of inspection circuit, waterways, temperature setting parameters and measured data, to identify the non-conformity and the corresponding corrections. When use the solenoid valve control the volume of water, checking the water level sensor sensitivity and the size of the water pressure, and determine that it is not the problem of the water level data.

Second, the control system determines the running of unit, and the system cannot be started without collecting the signal, because the unit open is jointly controlled by the temperature of the heat exchanger and the three parameters of the header tank temperature and set temperature. When the collected water tank temperature is below a certain value of the set temperature, the unit starts collector part of the water temperature is higher than a certain value of the storage tank temperature, when the collector tank temperature cannot collect the data, the unit will not start for the self-protection.

Cleaning the Upholstery Leather

Upholstery cleaning in many cases, is not its something special, a piece of cloth with clean water is more than enough. All interior cleaning with cleaning products must be moderate, if not gentle. Furniture decoration is more fragile than you think, so the best product is the removal of marinated, linseed oil, or any other water-based solution.

If you like to buy cleaning products from the big stores, you should avoid the formation of harsh chemicals. Spend most of their time sitting at home, lying on the sofa, so that the area of the furniture, it must be non-toxic. Already mentioned homemade solutions - flaxseed oil, white vinegar, is truly effective. Even real leather furniture manufacturer will guarantee it. You only need one part vinegar to two parts oil. Using the various solutions on the leather interior. With a clean cloth and apply to the leather mixed. Allow the layer stay for about 20 minutes, and then wipe the area with a clean cloth.

Another useful method is to use saddle soap or moisturizing soap to clean leather interior. Similarly, the best thing to do is to be used in about 20 minutes, and gently remove it. Ensure that the leather provided by an upholstery leather supplier is not too contusion. Otherwise, it may be damaged. Under normal circumstances, to avoid the formation of products of the leather, which contains excess grease. The same applies to the material, leaving a residue, such as waxes.

When it comes to cleaning the whole house, of course, on the surface should be ranked higher priority. As a leather furniture manufacturer says, interior and leather furniture may be hiding in your home than you can imagine under the surface. But with regular maintenance and cleaning, your home can spark and shine like brand new! Here are some reasons to clean your upholstery and leather furniture.

1. Oil and grease. Oil and grease on the surface of our furniture from our bodies to establish and reduce the quality of leather products as time goes on. Unfortunately, there is nothing you can do to prevent your body from these essential oils. Keep your leather furniture, frequent cleaning and care under special conditions.

2. Dirt and dust. If you suffer from allergies, there is a good chance that the cause of the problem provides the following (stuffy!) nose. Your leather furniture and skim the surface, you might find a collection of dust. The average household has accumulated nearly 40 pounds of dust, in any year, provides a lot of opportunities to improve their skills, dusting, vacuuming and cleaning.

3. Daily life. Like carpets, sofas often receive a lot of dust and dirt of the great outdoors. However, the end of this filth in your home? Busy lifestyle and a positive family made a huge contribution to the dirt brought indoors. To protect the quality of your furniture requires everyone to take a trip to the bathroom, clean up, and then lounging on the living room.

The term "beamhouse" refers to the processes in the tannery between the removal of skins or hides from storage and their preparation for tanning.

China Stamping Mold Industry has Large Development Space

Mold industry development status in 2012

Mold industry development in 2012 maintains a good momentum, mold companies orders are generally sufficient, full task, mold sales are 870 billion RMB, which an increase of 21% over the previous year. At the same time, China's mold production technology has been greatly improved, mold production level has approached or reached the international level. The experts said that modern manufacturing requires the Automotive Stamping mold industry to enhance mold technology content, to accelerate the pace of structural adjustment, to adapt to the new product upgrading.

Current situation of China mold industry

NC of mold processing equipment, no plans of mold design, the mold management information make the threshold of mold companies achieve a higher level, and the overall mold level has significantly improved. In view of import and export situation this year, the total mold imports are 20.47, 20.53 hundred million U.S. dollars, basically the same; the total mold exports are respectively 10.41, 14.13 one hundred million U.S. dollars, which is a year-on-year growth of 35.73%. The year-on-year growth remains strong upward momentum, at the same time deficit further declines, which means the high-tech content mold relying on imports situation has greatly improved, it’s time for domestic mold to replace imported mold, the imported and exported mold structure is more reasonable. This shows that the plastic rubber molds, stamping dies level progress is obvious, which remains relatively good higher level of development, mold export contribution rate remains at a higher basis. In addition, large-scale, sophisticated, complex, longevity upscale mold and mold standard parts development speed is faster than the general mold; the number of professional mold factories increases and the ability rises quickly.

Importance of stamping die manufacturing

Stamping die is a special technology and equipment to process material (metal or non-metallic) into parts (or semi-finished) in cold stamping. In recent years, with the pace of international continues to accelerate, growing market competition, people have become increasingly aware of the importance of product quality, cost and new product development capabilities. Metal Stamping Dies manufacturing is one of the most basic elements of the entire chain; stamping die manufacturing technology has now become an important symbol to measure a country's level of product manufacturing and one of the signs for the development level.

China stamping die industry development has much room in the future

It is reported that in recent years, stamping mold industry rapidly develops at about 15% growth rate, stamping dies industrial enterprises ownership forms have also changed dramatically, in addition to the state-owned specialized stamping mold factory, collective, joint ventures, wholly-owned and private also rapidly develop. With foreign companies entering into China, the competition is increased, and there are some vicious price competitions. In order to avoid the loss of the long-term and overall development due to temporary interests, the industry associations will strengthen the organization and coordination between the mold companies in the future, to develop a reasonable price level. Meanwhile, study the international mold price level; carry out guidance and information communication industry. It is visible that the China stamping die industry development still has much room in the future.

Two Types of Children's Wear for Buyers

In the previous chapter, the sourcing technique and the steps of placing OEM order have been detailedly highlighted. In this chapter, we would like to introduce the skill of selecting suppliers or manufacturers for various markets.

Profit is the most significant element which comes first in company's mind. Importers are always looking for low price and high quality things. However, it is not easy to find in the real market, Kids Wear Manufacturer. Price is always the refection of the quality. Actually, the successful business man should more look for the margin. Let's say, the over stock romper, sells at 0.5 USD per piece. The margin is only 0.1 USD. But the high quality dress, although its whole sell price is much higher, let's say 10 USD, the retail price would reach 30 USD. Therefore, when you select products, do not only focus on the import price. It would be more useful to consider how it can sell in your own market.




The sourcing agents usually search for the stock lot or large quantity of cancel order. The stock lots are sold at very low price with large quantity. These products are more suitable for distributors who already had certain degree of customer based or various distributional channels.

However, the over stock and cancel order may not be suitable for brands or small retailers. Brands have their own design and retailers which cannot match such large quantity. So what is the better supplier for brands and small retailers? The answer is turning to the trading company. Trading company has many catalogs at hand with small MOQ. Small retailer can select from the catalog by small order. For the own design production, the brand owner can have a one stop purchase from the trading company. We have mentioned that it is impossible for one factory to complete the whole collection. The trading company can save a lot of headache for you. They help you supervise the factory's work including quality control and shipping.

As a buyer, the whole sell price is not the only aspect that needs to focus. More attention should be paid to the evaluation of the predicted sells volume and the profit margin, Kids Wholesale Clothing. Also, it must make sure that which business type you are running, a sourcing agent, a brand owner or small retailer. The collection should be selected based on your business type.

Basic Knowledge about the Zippers

A. identification methods of zipper quality

Cloth tape: cloth tape is dyeing uniformly, undefiled, no scars, and soft to the touch, in the vertical direction or in the horizontal direction, the cloth with wavy.

Guitar and Guitar Bag

Classification of Guitars

By the playing style, guitars can be divided into classical guitar, acoustic guitar, Flamenco guitar, jazz guitar, Hawaiian guitar and the electric guitar these categories.

Acoustic guitars can be subdivided into Acoustic guitar and (rounded guitar) and cutting down (cutting down guitar). The former one is suitable for playing chords, while the latter one is suitable for playing high position solo. Acoustic guitar has a thin neck, with upper fingerboards 42mm wide, with totally 14 frets from the nut to the guitar body, a crescent-shaped shield on the guitar box, being played with a steel wire strings.



Classical guitar has wide fingerboards, small guitar body, being played with nylon strings, combined with the guitar body on 12th fret. It is generally used for playing the classical pieces, guitar song adapted from world music hits, music with multi voices, etc. Its performance type includes solo, trio, and so on.

By pickup and piano circuits conversion internal signals, electric guitar pronounces with the connect speaker. It can also be used with the effectors to create a rich timbre and sound effects, which is not available in an electronic acoustic band.

Guitar Bags

Guitar bags are package used to hold the guitar. They can be divided into bags for wood guitars and bags for electric guitars. Guitar bags sold at different prices have different protection effect. The difference between wood guitar bags and electric guitar bags lies in that the electric guitar bags are very thick, doped with materials such as sponge to prevent the electric guitar elements from damage. Wood guitar bags have many models, such as 39, 40, 41, and 42 inch bags. They can be shoulder bags or single shoulder bags with zippers.

Plastics and Plastic Packaging

Plastic is a synthetic or natural polymer resin as the main material. After adding various additives, it has ductility in a certain temperature and pressure; after cooling, the shape of a class of materials can be fixed. Natural or synthetic polymer resin molecules in the molten state and around the process of uniform distribution of additive molecules are called plasticizing; without plasticization this process is called un-plasticized. Plastic packaging is one of the four materials in the packaging industry: paper and paperboard accounted for 30%, 25% plastic, and 25% metal, and 15% for glass. The plastics can be used as Flexible Plastic Packaging in different fields.

Plastic classification

According to its performance, the plastic can be divided into two kinds: thermoplastic plastics (can be repeatedly melt-processability and can maintain the basic characteristics) and thermosetting plastic (can only be melt molding for one time). According to the uses it can be divided into general-purpose plastics which is wide used and cheap with better overall performance, such as PE, PP, PVC, PS, and amino plastics with good physical and mechanical strength. The other one is engineering plastics which can replace the metal used in construction, such as: ABS, nylon, polyester, POM, TPX-1, and a class of engineering plastics with particularly excellent in a performance, like special plastic with particularly good radiation resistance and high temperature resistance, such as poly (aryl sulfone), liquid crystal polymers and so on. According to the thermoplastic resin molecular crystal size, the plastic can be divided into thermoplastic amorphous polymer and crystalline polymers.



According to the Flexible Packaging Materials, plastic bags can be divided into OPP, CPP, PP, PE, PVA, EVA, composite bags, co-extruded bags and so on.

OPP plastic bag:
Characteristics: Hard, pulling without change. Non-stretch (two-way stretch) monolithic folded, side seal welding, the longest length can't exceed 640m/m.
Monolithic: 1.28M, width: 0.6m.

What is Third Party Inspection

The third party inspection (TPI) is inspection carried by the independent third party (such as a full-time supervision and inspection agencies) who is out of the trading interests. This party is fair and authoritative non-identity of the two parties. It inspects according to relevant laws, standards, contracts accepted by both sides basis for product compliance testing and accreditation activities. Third party inspection activities are relatively concentrated in industrial activities, particularly in the industrial manufacturing industry.

After signing the contract, during the execution of this contract, the buyer or the seller (relatively preferred less) engages an independent third-party company repeated the line against the seller of the contract of tracking and evaluation to ensure that the contract is valid, qualified to perform, thereby reduce risk.

The process

Buyers and sellers sign contract - the buyers or sellers hire third-party inspection - a third party inspection in accordance with the contract, standards, regulations, and other requirements- third party inspection report - buyers and sellers make requirements of the contract adjustment – third party tracking verification - report released after compliance.

From the initial pure product testing development to nowadays, the third party inspection has participate in the whole process of execution of the contract, such as feasibility analysis, risk assessment, contract evaluation, design review, process quality control, etc.

When can we use the TPI?

For example, company A needs to buy a high pressure reactor from company B. Because the equipment has high criticality and cost, in order to make sure the equipment provided by B is qualified, A can hire a third party inspection company to represent them to supervise the whole contract execution. Third party work may include: raw material audit, the audit of the welding process, welding engineering supervision, dimensional inspection, pressure test witness, visual inspection, file audits, etc.

Currently, there are tens of thousands third party inspection companies. The well known third party inspection companies with long history are:

Discussion on Soft Stand Up Pouch Bags

In recent years, along with the deepening of plastic industry and the technological innovation degree of packaging machinery industry, soft packaging technology has been rapidly developed. Soft packaging forms develop from flat shaped bags to special shaped bags and stand up pouch bags; the sealing methods are also diversified, such as heat sealing, zipper closure. Stand up pouch bags and special shaped bags gain the popularity among with end consumers and many downstream customers in the market by excellent shelf appeal, which have been widely used in the cosmetic industry and food packaging, becoming new highlights in soft packaging area, and reflecting a trend of replacing the traditional plastic bottles and glass bottles. There are many types of stand up pouch bags currently on the market, such as helical seal square bottom bags, and fold corner bags. Here normal three-side-seal fold corner stand up pouch bags will be taken as an example to discuss production technology and common quality problems solution of stand up pouch bags.

First, Production Technology

The biggest difference between three-side-seal fold corner stand up bags and ordinary flat bags lies in that the oval-shaped bottom bag requires secondary heat seal. Core of the entire production technology and equipment requirements are embodied in the bag strength, tightness and heat seal the end of symmetry. To produce high quality stand up pouch bags requires attention to the punch, dropping bag end, heat sealing, and other aspects. Particularly its four-storey and two-storey parts of the heat are extreme due to low heat seal strength and rupture. Thus heat seal cutter should be assembled to strengthen the local heat sealing.



1. Requirements for Materials

Because stand up pouch bags have high mechanical performance requirements for materials, they generally use composite membrane with more than three layers, with the following requirements to external, middle and inner material:

External material

External layer of printed materials, currently used, stand up pouch bag among general BOPP film, printing materials, BOPET, BOPA, high mechanical strength, high barrier properties of thin films. To select material based on usage, such as selection of BOPP, Matt BOPP film, are used to wrap solid products choice of BOPET or BOPA film used for packaging liquid products.

Middle-level materials

Middle managers generally opt for high strength, high barrier materials, BOPET, BOPA, VMBOPET, aluminum foil, etc. Inner material

Inner seal material, generally use the CPE or OPE, CPP has low heat seal performance of thin film and want to have good health and antistatic properties.

2. Requirements for Devices

Stand up pouch bags have special requirements on the structure of bag making machines. In addition to the roll device, double pendulum, sealing device, cutting unit, tension device, sensor devices of the three-side-seal bag making machine, there is an auxiliary device providing basic materials for stand up pouch bags.

Tips in the Selection and Use of Submersible Pumps

First, purchasing of submersible pumps

We should pay attention to the model, flow and head when buying submersible pumps. The selection of the inappropriate specifications will not be able to get enough water flow and the efficiency of the unit cannot be played. In addition, you should find out the direction of rotation of the motor, certain types of submersible pumps forward and reverse can be water, but the amount of water in the reverse current, reverse the damage to the motor windings. To prevent the leakage of submersible deep well pumps in underwater work and result in electrical shock and it should be installed leakage protection switch.

8" CAST IRON PUMP

Second, the installation of submersible pump

In the installation of submersible pump, cable should be overhead and power lines should not be too long. Do not allow cable force when the unit is in the water, in order to avoid power line break. Submersible pumps do not sink into the mud, otherwise it will lead to poor heat and burn the motor windings.

Third, the use of deep well pumps

1. Try to avoid the boot at low pressures. Power supply voltage and rated voltage should not differ by 10%, because the too high voltage will cause the motor to overheat and burn out the winding, while the too low voltage will make the motor speed drop, such as less than 70% of the rated speed, start the centrifugal switch will be closed, resulting in the start winding power and heat for a long time and even burn the winding and capacitor. The rotor pump do not frequently switch the motor, this is because the back flow when the pump is stopped, to immediately boot will start the motor load, the starting current is too large and burn winding.

2. Do not let the submersable well pump overload in the long term, do not pump the water with large sediment, the running time in the pump dehydration should not be too long, so as to prevent the motor overheating and burning. Units in operation, the operator must be observed at any time whether the operating voltage and current values specified on the nameplate, do not meet the motor stops running, identify the cause and troubleshooting.

3. We have to check the motor frequently, such as cover cracks, rubber seal ring damage or failure should be promptly replaced or repaired, to prevent the entering water.

Tips for the Selection of Nozzles

There are various types of nozzles, with wide range of options, and in general degreasing and washing step of the nozzle can choose a jet-type nozzle with strong impact force: and now we take the "V" type as the example, the angle of injection is best the 60 ° with a larger impact strength; phosphating process can use an atomization nozzle, water tablets fine uniform, weak impact fog nozzle cone nozzles: take the "Z" pattern as the example , the optimum distance of the nozzle is away from the workpiece 40cm ~ 50cm, with dispersion, the role of atomization of the liquid spray. Nozzles can be used in parallel and cross the two forms, on the channel type, with a vertical cross arranged to spray better.

The selection of the factors of the nozzle flow are pressure, spray angle, coverage, impact, temperature, materials, applications, and these factors are often implicated each other, mutual restraint. Flow and pressure, spray angle and coverage are proportional to the relationship. Any nozzle injection purpose is to maintain continuous so that the bath in contact with the workpiece, the flow of this factor is more important than the pressure. The temperature of the liquid does not affect the performance of the spray nozzle, but it affects the viscosity and specific gravity, but also influences the choice of materials. The nozzle material with the humidifier system should be determined based on the chemical properties of the bath, according to the ease of processing of non-corrosive bath, cast in bronze or plastic die-casting. To prevent corrosion, non-metallic materials can be used; the strong etching bath of sulfuric acid, hydrochloric acid, nylon plastic can be used; nozzle for phosphating bath material commonly used acid-resistant stainless steel to prevent rust nozzle can use stainless steel or nylon production.

The certain impacts are the small-angle nozzle plume flow (jet) for the best; fan nozzle for cleaning, degreasing, cooling conical nozzle suitable for bleaching cream, the surface layer, phosphide, humidification , dust, etc.; should be installed in the reservoir paint cylinder, tank Venturi mixing nozzle, the "H" type, ie mixing nozzle (also known as venturi nozzle), for example, is sucked into the bath after a certain pressure with the lead crossing the liquid common to 1:4 traffic mix after diffusion ejected achieve solute mixing effect of the air, thereby preventing the precipitation, because agitation to ensure the uniform mixing of chemical solution.
