The production process and special features of PE water supply pipe production line
The production process and special features of PE water supply pipe production lineIn recent years, China's conventional plastic extruders and production lines have gradually become popular in the international market with their excellent cost performance. At the same time, China continues to innovate in the field of advanced extrusion technology and has developed a variety of new extrusion products. Accurate extrusion molding can eliminate subsequent processing methods, better meet the needs of product applications, and at the same time achieve the purpose of reducing material costs and improving product quality. Nowadays, to meet the needs of accurate direct extrusion of plastic products, a variety of mature technologies have been introduced to the market, and polymer melt gear pumps are one of the important methods. This technology has been widely used in the production lines of chemical fiber, film, profile, pipe, plate, cable, composite extrusion, pelletizing, etc.
When making masterbatch to reduce production costs, it is often necessary to change the color. If you need to change the product, open the processing area within a few minutes. The color needs to use a lot of washing machine materials for cleaning, which is time-consuming, power-consuming, and waste of raw materials. . The split twin-screw extruder can solve this problem. The color changes, and the barrel can be opened quickly and manually cleaned in just a few minutes, so there is no need or less cleaning of materials and cost savings.

In the rotating twin-screw water supply pipe equipment, the material is similar to the positive displacement conveying in a gear pump. The heterodyne twin-screw extruder has low speed, low shear heat of the material, and is not easy to decompose. It does not require high thermal stability of the material. It is especially suitable for the molding and processing of heat-sensitive materials (such as PVC). Compared with the same-rotating twin-screw extruder, the counter-rotating twin-screw extruder has higher conveying efficiency, better exhaust effect and better melting effect. Although the dispersion and mixing effect of the material is worse than the same Xiang Shuangluoxuan extruder, it is more suitable for direct extruder to establish stable head pressure capability. In addition, replacing the single-screw extruder with a twin-screw extruder in different directions can save the pre-plasticization and granulation process, directly extrude PVC powder, and reduce product costs. The directional rotating twin-screw extruder is mainly used for the extrusion of PVC pipes, profiles, plates and pellets. Parallel heterodyne twin-screw extruders have also begun to be applied to large-scale PE water supply pipe production lines.
