In the process of PVC plastic pipe material production and processing, is very important for the control of the temperature, the smooth da plastic products factory in changshu here to discuss the production process for the production of PVC plastic pipe material for temperature control, hope you can understand!
general PV C plastic pipe processing temperature to molten tube billet export mode, with the appearance of smooth level off, the tube billet with moderate intensity is best. Extrusion processing temperature on the production line can be roughly divided into two categories, barrel temperature and mould temperature, cylinder temperature in order to ensure uniform pressure and plasticizing, cylinder should set temperature at 160 ℃ & ndash; — The range of 190 ℃. The die body temperature usually should be set at 165 ℃ Between 185 ℃. When pipe appear bleak appearance, or both inside and outside wall the plasticizing adverse symptoms such as obvious pins and needles, should raise the mold temperature, especially mouth mold temperature control at 190 ℃ 240℃。
the processability of PVC material is relatively narrow, and thermal stability is bad, so the processing temperature range is relatively narrow, poor adaptability to the machine and mold, usually at 160 ℃ Temperature between 210 ℃ and the specific need according to the different extrusion equipment, mould and different specifications.
