Differences between light calcium carbonate and heavy calcium carbonate in PVC-U pipe extrusion processing system
The differences in physicochemical properties between light calcium carbonate and heavy calcium carbonate were compared,and their application performance differences in PVC-U pipe extrusion processing system were analyzed and compared through rheological and extrusion tests using a torque rheometer.The main problems that may arise from replacing light calcium with heavy calcium and corresponding solutions were preliminarily explored.
