Enhance Heat Resistance, Toughness, Ductility
- Jan 30, 2018 -

PVC (Polyvinylchlorid), is PVC, in addition to other ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is a lacquer, with the main component in the center being PVC and the bottom layer being a back-coated adhesive. It is a favorite, popular and widely used synthetic material in today's world. Its global usage ranks second among all composites. According to statistics, in 1995 alone, there were about 5 million tons of PVC produced in Europe, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC average 1.4 million tons. PVC pipe (PVC-U pipe) PVC pipe is made of polyvinyl chloride resin and stabilizer, lubricant and so on with the hot pressing extrusion, is the earliest development and application of plastic pipe. PVC-U pipe corrosion resistance, easy bonding, low prices, hard texture, but due to the PVC-U monomer and additives seepage, only for conveying temperature does not exceed 45 ℃ water supply system. Plastic pipes are used for conveying drinking water, waste water, chemicals, heating fluids and coolants, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. Discrimination Method 1: Look at the surface finish, and whiteness. 2: take samples fall, easy to break up are generally high calcium products, of course, to meet your requirements at the right price is possible. 3: Take a sample of the edge of the pipe with the foot to see if it can crack, or rupture elongation after fracture. 4: weather. The most direct way is to get a place where high temperature and high light put a few days to see the rate of surface change, but it is a waste of time. Mainly look at the first three like. Application The essence of PVC pipe is a kind of vacuum plastic film, which is used for the surface packaging of various kinds of panels. So it is also called decorative film and adhesive film. It is used in many industries such as building materials, packaging, medicine and so on. Building materials industry accounted for the largest share of which was 60%, followed by the packaging industry, there are other small-scale application of the industry.
