Detailed Product Description: | In cleaning pipes | pvcu drain dn50 | Xuchang pvcu provide sewer pipe cleaning Central. 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, here we come to you analyze PVC pipe fittings discoloration problems: First, some sections in the processing will find the color is not uniform conditions, such as national color slight deviation is permitted. Then, some PVC pipe butler is obvious deformation occurred after heating yellowing. Again, if heated in good condition, 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, the production process of the profile, 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 pvcu drain, which also shows insufficient thermal stabilization efficiency, should increase the amount of thermal stabilizer added. The above is for PVC pipe fittings discolored introduction pvcu drain dn50, but be aware that adding fluorescent brighteners and other whitening additives in the formulation, if insufficient heat stabilizer, then the whitening effect is not obvious. PVC pipes appear profile bending causes and ways to produce PVC pipe fittings often appear bent or warped profile case, why is there such a phenomenon? We look at: this situation is the first reason given profile mold, traction machine and the head is not in a straight line, it should promptly adjust stereotypes die, traction position the machine; the second reason is that the material is not the head uniform pvcu drains price should be adjusted or trimmed mold; third reason is uneven cooling pvcu drain specifications, resulting in stress, you should adjust the cooling water or cooling water released; fourth reason is that the die temperature is uneven, resulting in internal stress, the temperature should be adjusted; fifth reason is out too fast, so that the cooling profiles bad, it should be appropriate to reduce the extrusion speed. I hope the above analysis we can help you find out the real reason for this situation and reasonable solution. |
