Selection of barrel tube.

The release date:2018-01-03
1. Feeding area: the deep groove of the fixed screw groove, the function of which is responsible for preheating and plastic solid conveying and pushing. It is necessary to ensure that the plastic begins to melt at the end of the feeding section -- that is, preheating to the melting point. The general length is: non-crystallinity (AS, ABS, ps) about 48~58%L, crystallinity (PA, POM, PE, PP, CA) about 48~58%L, and fiberglass about 45~55%L.
2. Compression zone: tapered spiral groove teeth deep, its function is plastic material melting, mixing, shear compression and pressure exhaust. The plastic will dissolve completely in this section, and the volume will shrink, so the design of compression is very important. The general length is: non-crystallinity (AS, ABS, PS) is about 25~35%L, crystallinity (PA, POM, PE, PP, CA) is about 22~32%L, and the addition of glass is about 28~40%L, thermal sensitivity (PVC)100%L.
3, measuring area: nanjing single-screw extruder screw fixed screw groove groove depth, mixing, melt conveying its main function, measuring, must also provide enough pressure, maintain stability of the melt temperature and flow of the molten plastic. The general length is: non-crystallization (AS, ABS, PS) of about 15~58%L, crystallinity (PA, POM, PE, PP, CA, etc.) about 48~58%L, with a glass of about 45~55%L.
