The Mechanism of Quasi-Dynamic Expansion Method and the Design of the Equipment for Manufacturing Biaxial Oriented PVC Pipes

Abstract:

Biaxial oriented PVC (PVC-O) pipes have great advanced properties: high intensity, high impact resistance, material saving etc. The new product can be used in many situations. There are more than three effect methods for manufacturing PVC-O pipes in foreign countries. Relevant researches have been preceded in some domestic institutes, but there are no effect processing methods and productive technologies have been reported. Based on plastics bulge forming and hop-pocket method, the quasi-dynamic continual expansion method (QDCE) is proposed in the paper. The key point of QDCE takes advantage of high elasticity、high compression ratio and high tear resistance of elastomeric materials, meanwhile designs production equipment and processing technology for manufacturing PVC-O pipes. We explore the mechanism of QDCE and design a whole package of expanding equipment.
