Description

PVC-O pipe, the Chinese name is biaxially oriented polyvinyl chloride, the latest evolutionary form of PVC-O pipe pipe. By using a special orientation process to manufacture the pipe (biaxial stretching technology), the UPVC(M) pipe produced by the extrusion method is used for the axial direction. Stretching and radial stretching, so that the long-chain PVC molecules in the pipe biaxially arranged in order to obtain high strength, high toughness, high impact resistance, crack resistance of the new PVC pipe. Tensile orientation mechanism of polymer materials The stretching orientation process of polymer materials is the process of the molecules arranged from disordered to ordered under the action of external force under the condition of temperature between the glass transition temperature and the melting temperature (usually near the softening point). Biaxial stretching is a process in which a material is biaxially stretched to make the strength perpendicular to the the stretched surface of the biaxial stretching that superimposed on the strength of the stretched surface direction, thereby increasing the strength of the material in the direction of the stretched surface. Ratio and stretching rate Stretching orientation, in the simplest sense, is to straighten the curled molecular chains and align them in the direction of stretching. Increasing the stretching ratio appropriately increases the degree of molecular orientation and increases the strength of the material. However, excessively increasing the stretching ratio will lead to material damage, In plain terms, the molecular chain of the material is broken and the material is destroyed.
