1.Reduce the amount of filler used. Ultra fine lightweight activated calcium carbonate, even nano-sized calcium carbonate, is commonly used, which not only increases rigidity and filling, but also has a modifying effect. The general dosage is controlled at 20-50 parts by mass. Try to use as little heavy calcium carbonate as possible. Due to the irregular particle shape and relatively coarse particle size of heavy calcium carbonate, its compatibility with the PVC resin body is poor. When added in large quantities, it will have a negative impact on the color appearance and performance of the pipe
T2.he appropriate amount of impact modifier should be used, and multiple impact modifiers should be used in combination as much as possible to improve the effect of impact modification
3.Adopt a reasonable stable system and try to use composite heat stabilizers to improve the thermal stability effect and reduce the amount of heat stabilizers used
4.Choose appropriate external lubricants and minimize the amount of lubricant used
