Basic Principles and Processes of PVC Pipe Production
The fundamental principle of PVC pipe production involves heating polyvinyl chloride (PVC) particles to a molten state and then extruding them through a machine to achieve the desired dimensions and shapes of the pipe product. The process of PVC pipe production mainly comprises the following steps:
1.Preprocessing of PVC Particles: Raw PVC particles are dried and mixed to ensure the quality and performance of the final pipe.
2.Melting of PVC Particles: By subjecting PVC particles to high-temperature heating and mechanical mixing, they are melted into a malleable molten state.
3.Extrusion Molding: The molten PVC is extruded through a machine, where it is heated and compressed, taking the shape and dimensions of the mold to form the pipe.
4.Cooling and Solidification: The extruded pipe is rapidly cooled through methods like water or air cooling to solidify it and maintain the desired shape.
5.Cutting and Inspection: The cooled and solidified pipe is cut, and finished products undergo quality inspection to ensure compliance with relevant standards and requirements.
