PVC plastic pipe material suitable for storage and transportation of hot water, heat and all kinds of waste liquid chemical solution.
If there is one on the forming of CPVC pipe raw material is larger than a graphite packing, can also be used for heat pipe.
CPVC plastic tubing used in domestic is just started in recent years, many applications in the cold, hot water pipelines;
Long-term use of transfusion, the highest temperature is 120 ℃, life can be up to 40 years.
PVC plastic pipe extrusion molding mainly by raw material is the chlorine content is more than 61%, 110 g/mL, or so of water phase suspension method chlorinated polyvinyl chloride (PVC) resin, and then mixed with a few auxiliary material.
Changshu smoothly da plastic products factory talk about PVC plastic pipe material selection of auxiliary materials required at 8 o 'clock!
PVC plastic pipe material of auxiliary materials stabilizers, lubricants, impact modifier, filler and other auxiliary materials selection should pay attention to the following requirements at 8 o 'clock.
1, the choice of auxiliary material with CPVC resin has good compatibility.
2, use less as far as possible to reduce the CPVC resin heat resistance, resistance to chemical corrosion resistance, weather resistance and flame retardant additives.
3, choose can improve the CPVC resin auxiliary material thermal stability, impact resistance, prevent the CPVC molten material under the condition of high temperature decomposition occurs.
4, additives should be able to improve the liquidity of CPVC molten material, to reduce the gel time and temperature, in order to reduce the molten material stick on the surface of equipment parts and mould.
5, can promote the CPVC material plasticizing, to reduce the melt pressure, is advantageous to the molten material forming, reduce cooling stereotypes of stress.
6, additives performance is stable, not easy to migrate.
7, conveying water CPVC plastic pipe molding materials, non-toxic additives should be added to the formula, raw materials of health indicators should comply with the GB: & quot; T 17219 1998 standard regulation. Also can add some price of PVC resin SG5 type, two kinds of raw material quality and for 100. Pipe forming materials, for example, the formula of CPVC resin quality for 90, PVC, resin quality of 10; Such as the quality of PVC resin in the recipe for 4 0, then the quality of the CPVC resin is 60.
