compression zone (compression zone) This section is tapered screw groove groove depth, its function is plastic raw material melting, mixing, shear compression and pressure exhaust. Plastics will dissolve completely in this segment and the volume will shrink, so the design of compression (compression ratio) is very important. The general length is: Amorphous: about 25~35% L... (AS, ABS, PS, etc.) Crystallinity: About 22~32% L... (PA, POM, PE, PP, CA, etc.) : About 28~40%L PVC: 100%L 3. Metering zone This section is fixed groove depth of the screw groove. Its main function is mixing, melt transfer, and metering. It must provide enough Pressure, maintain uniform melt temperature and stabilize the flow of molten plastic. The general length is: Amorphous: about 15~58% L... (AS, ABS, PS, etc.) Crystallinity: about 48~58% L... (PA, POM, PE, PP, CA, etc.) : About 45~55%L Although the plasticizing screw can be distinguished according to the function or geometric appearance, in the actual plasticizing process, the functions of each section overlap, and it is difficult to distinguish the intervals. The study of plasticizing screws is nothing more than thinking
First, increase the role of dispersive mixing.
Second, improve uniform mixing (dispersive mixing).
Third, improve the plasticizing capacity (plasticating capacity).
Fourth, improve the melt temperature uniformity. The deeper the depth of feed in the feed section, the greater the delivery volume, but the larger the required torque of the screw; the depth of the feed section is too shallow, the delivery volume is insufficient, and the compression ratio is insufficient. When the tooth depth of the measuring section is too deep, the compression ratio is insufficient, and the required feeding force is large; when it is too shallow, it is easy to overfire and scorch. General tooth depth is about 0.03~0.07 times the screw diameter. Therefore, the plastic plasticizing screw has functions of conveying, melting, mixing, compressing and metering, and plays an important role in the quality of plasticization.
