Product Introduction
Second hand pvc pipe making machine, this machine is equipped with a quantitative feeding device, so that the extrusion amount and the feeding amount can be matched to ensure the stable extrusion of the product. Due to the characteristics of the tapered screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are relatively large, which is conducive to the plasticization of the material. The diameter of the screw in the metering section is small, which reduces the heat transfer area and the shear speed of the melt, so that the melt is extruded at a lower temperature. When the screw rotates in the barrel, the PVC mixture is plasticized and pushed to the nose, so as to achieve compaction, melting, mixing and homogenization; and to achieve the purpose of exhaust and dehydration. The feeding device and the screw drive device adopt frequency conversion and speed regulation, which can realize synchronous speed regulation.
Product feature and application
Second hand pvc pipe making machine, refers to the main raw material for making pipes is PVC resin powder. Second hand pvc pipe making machine are generally divided by the purpose of the pipes: drainage pipes, water supply pipes, wire pipes, and cable sheaths.……
Because there are differences in the formula of raw materials, the compressive properties of various types of pipes and other indicators are different.
PVC water supply pipes are used in conjunction with water supply fittings for water supply projects in buildings.
Because of its characteristics, second hand pvc pipe making machine are widely used in oilfield crude oil collection and transportation, temperature-resistant and corrosion-resistant pipelines for chemical industry, hot water and warm water supply and drainage pipelines, direct buried high-voltage ultra-high-voltage power transmission, cable protection pipes and other fields.
PVC drain pipe is used for sewage discharge.
