PVC (full name Polyvinylchlorid), the main ingredients of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table uppermost layer mask is painted, the main ingredient in the middle of polyvinyl chloride, the lowest layer 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's the second highest in the global use of a variety of synthetic materials. According to statistics pvc pipe, just 1995 year, PVC production capacity in Europe, there are about five million tons of plastic pvc pipe, 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) Rigid PVC pipe is made of PVC resin and after stabilizers, lubricants, etc. with using hot extrusion method, is the first to get the development and application of plastic pipe. PVC-U pipes strong anti-corrosion, easy adhesion, low prices, hard, but because there are PVC-U monomers and additives exudate, only applies to transport temperature does not exceed 45 ℃ water supply system. Plastic pipe for conveying applications drinking water, wastewater, chemicals, heating fluid and coolant, food Qingdao pvc pipe, pvc pipe standard ultrapure liquids, slurries, gases, compressed air and vacuum systems. Hard PVC pipe has a nominal diameter of 50CM, but soft PVC pipe is generally the largest of 50mm. pvc pipe fittings rigid PVC pipe specifications: GB / T13020-1991 soft PVC pipe specifications: GB / T13527.1-1992 hard PVC pipe has a nominal diameter has :( units mm) 2.5,3,4,5,6, .. ... 355,400,450,500,560,630,710,800,900,1000 and other PVC-U and the difference between UPVC and UPVC PVC-U is, we usually say that PVC pipe, but the wording is just not the same sequence . PVC production process, in order to increase the performance of PVC plastics, increase productivity, added plasticizers (such as DOP, DBP, DINP, etc.), and add the plasticizer in PVC products will be relatively soft. Generally, we will not be added during processing plasticizer of PVC products collectively known as UPVC, also writing PVC-U. pvc pipe pipe _ quote _pvc sea Widex (view) provided by Qingdao Rubber Material Co., Ltd.
