Detailed Product Description: | Clean the drain pipe _pvcu in price _ Luoyang pvcu sewer pipe cleaning provided by China. We are Zhejiang Jie Pipeline Ltd., Zhengzhou Office (www.pprgc.com) at: Zhengzhou specializes in: PP-R hot and cold water pipes, F-PPR performance glass fiber reinforced composite pipes, PP-R aluminum on PVC pipe fittings discoloration Sometimes we found PVC pipe fittings discoloration phenomenon pvcu drain, here we come to you analyze PVC pipe fittings discoloration problems: First, some sections in the processing will find the color is not uniform, the such as the National slight color deviation is permitted. Then, some PVC pipe butler is obvious deformation occurred after heating yellowing. Again, if in good condition after heating pvcu drain pipe, but there will be door profiles made not long dimmed phenomenon; profiles in normal production is not yellow, and in the subsequent window products into yellow. Further pvcu drain fittings, the profile production process, when the basic conditions of raw materials and mold, etc. does not change, if the plasticizing section and the homogenization temperature of the segment increased by about 5 ℃, the profile generated by the occurrence of yellowing tendency, This also shows that the efficiency of their lack of thermal stability, should increase the amount of thermal stabilizer added. These are the introduction PVC pipe fittings for discoloration, but be aware that when you join a fluorescent brightener pvcu drains and other whitening additives in the formulation, if insufficient heat stabilizers, then the whitening effect is not obvious. About Prospect of PVC pipe fittings with pipe housekeeper range of applications in production now increasingly widespread, PVC pipe fittings are now more popular with consumers on the social product. Situation PVC pipe industry, scientific and technological development as one of the products, PVC pipe in everyday life can and striking. In Europe, 1980 - 1990 growth rate of 8 percent of plastic pipe, 2001 the annual output of 3.5 million tons, which accounted for 60% of PVC pipe. 1985 US production was 1.6 million tons of plastic pipe, 1999 annual output of about 3.6 million tons, of which, PVC pipe accounted for 78%. And China's first root UPVV flared tubing is in 1983 in Shenyang Plastic Factory (now Shenyang Giuly's predecessor) was born, and since then, China has the PVC, drainage capacity. The late 1990s is a period of rapid development in mainland China PVC pipe. During some of the more than 50,000 tons annual capacity in factories are built and put into operation, tons more than the scale of production of more than 30 PVC pipe factory. The current annual production capacity of 2 million tons of plastic pipe above is summarized in the professional manufacturers for everyone on PVC pipe fittings Prospect, more knowledge about the development of PVC pipe fittings, please call us. |
