PVC is the abbreviation of polyvinylchloride. Its main component is polyvinyl chloride. It is a material that adds other components to enhance its heat resistance, toughness and ductility. The top layer of this surface facial mask is paint, the main component in the middle is PVC, and the bottom layer is back coated with adhesive. UPVC has excellent chemical resistance in the whole working temperature range and a wide range of working pressure bands. Due to the long-term high strength, stiffness and cost-effectiveness, UPVC systems account for a considerable proportion of plastic pipe installations.
Pipe advantage
1. it has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes.
2. low fluid resistance: the pipe wall of PVC-U pipe is very smooth, and its resistance to fluid is very small. Its roughness coefficient is only 0.009. Its water conveyance capacity can be 20% higher than that of cast iron pipe with the same diameter, and 40% higher than that of concrete pipe.
3. excellent corrosion resistance and drug resistance: PVC-U pipe has excellent acid, alkali and corrosion resistance, and is not affected by moisture and soil pH. no anti-corrosion treatment is required during pipe laying.
4. good water tightness: the installation of PVC-U pipes has good water tightness whether they are connected by bonding or rubber ring.
5. bite prevention: PVC-U pipe is not a nutrient source, so it will not be eroded by rodents. According to the test conducted by the National Health Foundation in Michigan, rats will not bite PVC-U pipes.
6. Performance test: curing time shrinkage splitting strength tensile property peel strength thermal stability application period storage period release of harmful substances.
