● Reducing costs:
Calcium carbonate is relatively cheap. Adding calcium powder can reduce the amount of 폴리염화비닐 resin used, thereby reducing material costs and improving economic benefits.
● Enhancing rigidity and hardness:
Calcium carbonate, as a filler, can improve the hardness, rigidity and dimensional stability of PVC pipes and enhance the compressive strength of pipes.
● Enhancing thermal stability:
The pH value of calcium carbonate is alkaline, which can absorb hydrogen chloride, and to a certain extent enhance the thermal stability of PVC, preventing the pipe from decomposing due to high temperature during processing.
● Improving processing performance:
Calcium carbonate helps to improve the processing fluidity of PVC pipes during the production process and improve the efficiency and effect of extrusion molding.
