PVC (full name Polyvinylchlorid) pvc pipe order, the main component of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top layer mask is painted, the main ingredient in the middle of the PVC, the lower is the adhesive-backed. the nature of the application of pvc pipe PVC pipe is a vacuum plastic film for packaging various types of panel surface metal pvc pipe, it is also known as decorative films, with film, used in building materials, packaging, pharmaceutical and other industries . Building materials industry accounted for the largest proportion, 60 percent, followed by industry, packaging industry, there are a number of other small-scale applications. PVC pipe is divided into two kinds of PVC water supply and drainage, water supply and drainage for municipal and industrial water supply and drainage, civil drainage, irrigation, watering and other vegetation. PVC pipe is generally available in three-way split manifolds or vertical split stopcock. During the construction, to add a saddle fitting together two half-way, and with a U-bolt clamp, thus thickening of the wall, and then on top of drilling directly open bite, and then pick out externally threaded plastic parts. After tests showed that this method of construction can be achieved acceptance pressure test specifications. Also the water in the tube to produce thrust position, such as elbows, tees and pipe end closure panels and other parts should be set at the pier to withstand water thrust thrust. PVC pipe as a new non-metallic pipes, metal pipes with existing detection equipment can not detect its exact location, but if the buried pipeline construction in the pipeline above a buried wire can easily solve this problem. PVC is the biggest characteristic is flame retardant, so it is widely used in fire protection applications. But PVC in the combustion process releases hydrogen chloride and other toxic gases pvc pipe, such as dioxins. PVC combustion in two steps. First at 240 ℃ -340 ℃ combustion and decomposition of hydrogen chloride gas having a double bond diolefin, and then combustion of carbon occurs at 400-470 ℃. It is one of the world's largest production of plastic products, cheap, widely used in polyvinyl chloride resin is white or pale yellow powder. Depending on the use of different additives can be added, PVC can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer in PVC resin can be made from a variety of hard, soft and transparent products. Pure PVC density 1.4g / cm3, adding plasticizers and fillers, such as the density of PVC plastic is generally 1.15-2.00g / cm3. Rigid PVC has good tensile, flexural, compressive strength and impact resistance, can be used as structural materials alone. Soft PVC softness, elongation at break, cold resistance will increase, but the brittleness, hardness ,, tensile strength is lowered. PVC has good electrical insulation properties, can be used for low-dielectric material, its chemical stability or. Due to poor thermal stability of PVC, prolonged heating can cause decomposition and emit HCL gas pvc tube manufacturers, polyvinyl chloride change color, so its narrow range of applications, the use temperature is generally between -15 ~ 55 ℃.
