Durable: excellent anti climate, also cannot be corrupted by bacteria and fungi. Small resistance, high flow rate: the inner wall is smooth, fluid flow loss is small, the dirt is not easy to adhere to the smooth wall, maintenance is relatively simple, low maintenance costs.
PVC pipe fittings: PVC is polyvinyl chloride, is a kind of plastic products produced by 43% of oil and 57% of salt. Compared with other kinds of plastic products, PVC is more effective use of raw materials, reduces fuel consumption. At the same time, the energy consumption of PVC manufacturing industry is also very low. And in the late stage of the use of PVC products, can be recovered and converted to other new products or burned to get energy.
PVC in the production will be added to the stabilizer, but the stabilizer is non-toxic and toxic, only by adding a lead salt and the like of toxic stabilizers, will produce hidden dangers. But the PVC product of some small businesses to use dragons and fishes jumbled together, lead salt stabilizer, it is difficult to reach the relevant health standard. Consumers in the choice of PVC materials, it is best to a regular credit to ensure the quality of building materials market to buy, and require the supplier to issue inspection report.
