When the purchase of visual valves, the surface should be no blisters; plating surface should be uniform, should pay attention to whether there is peeling, cracking, scorching, exposed, flaking, dark spots and obvious pitting and other defects; spray surface tissue should be fine, smooth Uniform, no sagging, exposed defects. First, understand the valve knowledge: Civil valves commonly used in ordinary households commonly used gate valve, ball valve, triangular valve and other forms, usually iron or copper. As the mechanical properties of copper alloy, with less rust, corrosion resistance advantages, so the copper valve has gradually replaced the iron valve. Triangle valve surface are basically used electroplating, its role is not only to control the flow of pipeline media, but also play a decorative role. Triangle valve is generally connected to the pipe and water hose for the faucet, toilet water supply, there are connecting pipes and water hoses for water heater. Gate valve is basically used for the connection of pipe and water meter; the ball valve is used for the connection of pipeline and water heater; the ball valve is more convenient than the opening and closing than the gate valve. At present, most of the connection between pipe and water meter adopts ball valve. Second, to master the purchase of civil valves should be based on the different requirements of users choose different types of household valves: 1. Valued purchase when the valve, the surface should be no blisters; plating surface should be uniform, should pay attention to whether there is peeling, cracking, scorching, exposed, flaking, dark spots and obvious pitting and other defects; spray surface tissue should be fine , Smooth and uniform, no sagging, exposed defects. The above defects will directly affect the service life of the valve. 2. Valve pipe thread is connected with the pipe, the purchase of visual inspection of the surface of the thread has no dents, broken teeth and other obvious defects, it is important to note that the effective length of the pipe thread and the screw connection will affect the reliability of the seal Sexuality, purchase should pay attention to the effective length of pipe thread. General DN15 cylindrical thread effective length of about 10mm. 3. Gate valve, ball valve is generally marked on the valve body or handle nominal pressure, optional according to their own needs. 4. Replace the existing gate valve or ball valve, we must find out the length of its structure, so as not to buy after the installation. 5. Triangle valve pipe thread with internal and external thread two, according to the need to buy; also note that there is currently on the market part of the triangle valve made of zinc alloy, the valve price is lower than the average product, but Corrosive and cause rupture. 6, should be as regular as possible in the building materials stores, shopping malls, so product quality can guarantee.

PLA Plastic Bags Fully degradable plastic bags use bio-based as the base material, and the raw materials are made from starch or corn flour, which are renewable resources that can be completely decomposed. Coupled with some modified starch materials with good ductility, elongation at break, heat resistance and impact performance, the fully degradable plastic bag has excellent packaging function and is widely used in clothing, apparel, accessories, food, Hardware, electronics, cosmetics and other industries. Fully degradable plastic bags will decompose into carbon dioxide, water and other small molecules and exist in nature. And the decomposition is completed, it takes about 180 days. The development of fully degradable plastic bags is the general trend, and traditional plastic products will eventually be replaced by degradable products.

HDPE is a highly crystalline, non-polar thermoplastic. The appearance of the original HDPE is milky white. HDPE is a thermoplastic polyolefin produced by the copolymerization of ethylene. Although HDPE was introduced in 1956, the plastic has not yet reached maturity. This versatile material is constantly being developed for new uses and markets. It is translucent to a certain extent in the thin section. PE has excellent resistance to most household and industrial chemicals. Certain types of chemicals are chemically aggressive, such as aggressive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapour resistance for packaging applications. HDPE has good electrical properties, especially high insulation dielectric strength, making it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance at ambient temperatures and even as low as -40F. The unique properties of the various grades of HDPE are the appropriate combination of four basic variables: density, molecular weight, molecular weight distribution, and additives. Different catalysts are used to produce tailor-made polymers with special properties. These variables combine to produce HDPE grades for different applications; achieving the best balance of properties. PE can be manufactured with a wide variety of different processing methods. Using ethylene as the main raw material, propylene, 1-butene and hexene as the copolymer, under the action of the catalyst, the slurry polymerization or gas phase polymerization process is adopted, and the obtained polymer is flashed, separated, dried, granulated, etc. process to obtain a finished product with uniform particles. These include, for example, sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotational molding.

Shrink Film The shrink film has high puncture resistance, good shrinkage and certain shrinkage stress. Mainly used in the sales and transportation process of various products to stabilize, cover and protect products. Shrink packaging not only looks beautiful, but also plays a role in moisture-proof, dust-proof, loose-proof, anti-theft and collection. Shrink film is used in the sales and shipping process of various products. Its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinking process, the film cannot create holes. Since shrink films are often used outdoors, UV anti-ultraviolet agents need to be added. Including OPS/PE/PVC/POF/PET shrink film 1) PE heat shrinkable film is widely used in the whole package packaging of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance and tear resistance, and is not easy to break. , not afraid of the tide, the shrinkage rate is large; 2) PVC film [1] has the characteristics of high transparency, good gloss and high shrinkage; 3) POF has the characteristics of high surface gloss, good toughness, high tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film. POF is the meaning of heat shrinkable film. POF stands for multi-layer co-extruded polyolefin heat shrinkable film. It uses linear low density polyethylene as the middle layer (LLDPE) and copolymerized polypropylene (pp) as the inner and outer layers. It is extruded out of the machine, plasticized and extruded, and then processed by special processes such as die forming and film bubble inflation. 4) OPS shrinkable film (oriented polystyrene) heat shrinkable film is a new type of packaging material with ops heat shrinkable film body that meets environmental protection requirements. OPS heat shrinkable film has high strength, high rigidity, stable shape and good gloss. degree and transparency. It is easy to process, easy to color, has good printing performance, and has a very high printing resolution. For trademarks that constantly pursue exquisite printing, it is a complete improvement in material. Due to the high shrinkage rate and strength of OPS film, it can be closely attached to containers of various shapes, so it can not only print exquisite patterns, but also meet the use of various novel packaging containers with different shapes. This non-toxic, odorless, grease-resistant, food-hygienic film allows designers to use eye-catching colors to achieve 360° label designs, giving full play to creativity and imagination, so that beverages and other products can be used on labels. In-use patterns are more vivid, highlighting the image on the shelf, creating an unexpected container effect. 5) Characteristics of PET heat-shrinkable polyester film: it is stable at room temperature, shrinks when heated (above the glass transition temperature), and heat shrinks more than 70% in one direction. The advantages of heat shrinkable polyester film packaging are: 1. The body is transparent and reflects the image of the product. ② The packaging is tightly bundled, and the anti-scattering property is good. ③ Rainproof, moistureproof and mildew proof. ④No recovery, there is a certain anti-counterfeiting function. Heat shrinkable polyester film is often used in convenience food, beverage market, electronic appliances, metal products, especially shrink label is its main application field. Because with the rapid development of PET beverage bottles, beverage bottles such as Coke, Sprite, and various juices need PET heat shrinkable films to be matched with them as heat-sealing labels. They all belong to polyester, which are environmentally friendly materials and are easy to recycle. use. In addition to being used as shrink labels, heat shrinkable polyester films are now also used on the outer packaging of daily commodities. Because it can not only protect the packaged items from impact, rain, moisture and rust, but also make the product win users with beautifully printed outer packaging, and at the same time it can well show the good image of the manufacturer. Today, more and more packaging manufacturers use printed shrink film to replace the traditional transparent film. Because the printing shrink film can improve the appearance of the product, it is conducive to the advertising of the product, and can make the trademark brand have a deep impression in the minds of consumers.
