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

Abstract:

Due to the biaxial oriented PVC (PVC-O) pipes have a great improvement in the strength, heat resistance, modulus, and impact resistance, etc. So the new products can be used in many situations. Referring to the foreign Mouth die drawing method, the mechanism of quasi-dynamic expansion method is proposed in the paper. We chose the hard polyvinyl chloride (PVC-U) pipes for raw materials, through the forward movement of the pipe match with the vertical reciprocating movement of the expansion parts, improve the design of a whole package of biaxial oriented self-reinforced pipe continuous production device. The device has great advanced properties: small expansion friction resistance, high hoop extension ratio, simple production device, production line is easy to start etc.
