PVC (full name Polyvinylchlorid) pvc injection pipe supply, the main component of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top layer mask is painted pvc injection pipe, the middle is the main component of PVC injection pvc pipe prices, the lowest is coated with an adhesive backing. It is loved by the world, is quite popular and is also widely used as a synthetic material. It ranks second in the global use of a variety of synthetic materials. According to statistics, in 1995 only a year, PVC production capacity in Europe, there are about five million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption by an average of 1.4 million tons. PVC pipe (PVC-U pipes) hard PVC pipe is made of PVC resin and rear stabilizers, lubricants, etc. with the law by hot extrusion, was the first to get the development and application of plastic pipe. PVC-U pipe corrosion resistant, easy bonding, low price, hard, but because there are PVC-U monomers and additives exudation, applies only to transport temperature does not exceed 45 ℃ water supply system. Plastic pipe used to transport drinking water applications, wastewater, chemicals, heating fluid and coolant, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. pvc identification may also be determined by measuring the material to determine whether it contains chlorine, but because the vinyl chloride copolymer, polychloroprene, polyvinylidene chloride, chlorinated polyvinyl chloride and so contains a higher proportion of chlorine, but also the color by pyridine reaction to identify. Note pvc injection pipe wholesale, before the test, the sample must be extracted with ether to remove the plasticizer, Test method: take over from ether benzene sample was dissolved in tetrahydrofuran, the insoluble components, methanol was added for precipitation, and extraction below 75 degrees after the former dry. The dried small sample need not react with 1ml of pyridine, in a few minutes, add 2 drops of 5% methanol in presence of sodium hydroxide solution (1g of sodium hydroxide was dissolved in methanol then 20ml), immediately look colors, 5min and 1h were observed once again. Identification of different colors according to the chlorine plastic. Qingdao injection pvc pipe, pvc injection pipe, sea Widex Widex provided by Qingdao Rubber Material Co., Ltd.
