PVC Pipe Fittings Heat Resistance, Toughness, Ductility

PVC (full name Polyvinylchlorid) is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, PVC production in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averages 1.4 million tons. PVC pipe (PVC-U pipe) Rigid polyvinyl chloride pipe, which is made of polyvinyl chloride resin and stabilizer, lubricant, etc., is extruded by hot pressing, and is the earliest plastic pipe material developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45 ℃. Plastic pipes are used to transport drinking water, wastewater, chemicals, heating and cooling liquids, food, ultrapure liquids, slurries, gases, compressed air and vacuum system applications. Discrimination method 1: First look at the surface finish and whiteness. 2: Throw samples, and those who are easy to break are generally high-calcium products. Of course, it is possible to meet your requirements if the price is appropriate. 3: Take the sample and step on the side of the pipe with your feet to see if it can crack or the elongation at break after cracking. 4: Weather resistance. The most direct way is to get a place with high temperature and high light for a few days to see the rate of surface change, but it is a waste of time. Just look at the first 3 items.
