During the extrusion process of PE, PPR and PVC in the extruder, the molten material is transported to the die through the filter screen. The filter screen can filter the materials and improve the mixing effect of materials. However, the filter screen can also make the process fluctuate, resulting in the rise and sometimes decrease of back pressure and molten material temperature.

The reason why some rigid PVC processors are unwilling to use the filter screen is that the filter screen will raise the temperature of PVC molten materials and be prone to degradation, which requires materials with better thermal stability, thus increasing the cost of materials. If PVC special filter screen changer converter is used, the cost will also be increased. Therefore, most rigid PVC processors either avoid using the filter screen or use the coarse filtration device without converter to filter only the impurities of larger particles.

PVC pipes need its special screen changer to solve these problems. In the pipe industry and special pipe special non-stop screen changer, we recommend to use the special screen changer for pipes on the pipe unit with large length diameter ratio, high melting pressure and high output. Our office owns all intellectual property rights. It is equipped with voltage stabilizing, bypass auxiliary system, automatic lubrication and sealing mechanism, and the melting pressure of the main body of the screen changer is up to 60MPa. During network change, "relay" automatic exhaust, bypass "early intervention system" stable pressure and flow, continuous production without shutdown, and no material leakage. It is especially suitable for the production of gas pipe, water supply pipe, drainage pipe, reinforcing pipe, composite pipe and various large municipal pipes.

After installing the hydraulic screen changer, it can not only filter out impurities, but also greatly improve the plasticization and homogenization effect of raw materials. The product has more uniform texture, better surface quality and finish. In addition, the filter screen can be replaced without shutdown, which saves energy and reduces consumption. At the same time, it improves the output and reduces the labor intensity. info@battemachinery.com
