PVC water pipe fittings is how to manufacture

PVC pipe in the decoration, the application of the very much. But how much do you know about the production process of PVC pipes? General PVC pipe in the production of time to go through the mixed process; Extrusion process; Molding process; Traction technology.
The following is a detailed description of each process.
Mixing process PVC pipe in high speed mixing, additives into the PVC resin gap, so that the additives in the resin evenly dispersed, considering the temperature of more than 1000C is conducive to the material steam evaporation, so the general temperature of the hot mixing machine is set in 100~1200C. In order to make the additives fully in contact with PVC particles, reduce the filling
The adsorption of additives by the filling agent should start the hot mixing machine immediately after adding PVC resin, and then feed in the following order: stabilizer, various processing AIDS, color, filling agent. In the actual production, it is mostly to start the hot mixer after all the raw materials are put into it. So let's do that. The first part is complete.
Extrusion molding process. The temperature of the cylinder in the solid conveying area is generally controlled at 100~1400C. If the feeding temperature is too low, the solid conveying area will be extended and the length of the plasticizing area and the melt conveying area will be reduced, which will cause bad plasticization and affect the product quality. In the third. A tube extruded from a die at the end of a machine
It must be cooled to harden and set. Usually, sizing sleeve is used for outer diameter shaping and inner diameter shaping. Among them, the outside diameter finalizing structure is relatively simple and easy to operate, which is widely used in China.
Traction technology. The function of the traction device is to provide a certain traction force and traction speed for the pipe extruded by the head, draw out the pipe evenly, and adjust the wall thickness of the pipe by adjusting the traction speed. Traction speed depends on the extrusion speed. Generally, traction speed is 1%~3% faster than extrusion speed.
General PVC pipe to go through these steps of the process to produce.
