Plastic Modification---ABS/PC；PA/ABS；PPO/PS Compounding Pelletizing line.
1. High output. Twin screw extruder adopts high torque high rotation speed gear box, matched with novel wear-resistance barrel and screw, torque grade 9~11T/A3, the maximum torque grade can reach as high as 15 T/A3.
2. High degree of automation of complete set of production line. Automation includes material storage and conveying, weighing mixing and metering feeding, compounding and pelletizing, automatic packing, finishing the whole process from material to product granule.
3. Multiple equipment large-scale and integrated production. The automatic centralized control system is adopted to share capital construction and environmental protection facilities, effectively reduce various production and operation costs (such as raw material procurement and transportation cost, labor cost, equipment procurement, capital construction cost, etc.)
Process description:
The compounding modification of more than two kinds of resins is mainly aimed at the modification of processing flowability and mechanical properties. The two resins of alloy modification have good compatibility, close processing temperature and complementary characteristics, such as ABS/PC alloy, PPO/PS alloy, PA6/ABS alloy and so on. The raw materials are often premixed, and after uniform mixing, the feeder is fed into the twin-screw extruder, and some formulas require the addition of liquid additives in the middle of the barrel. Then finish the process requirements of compounding dispersion, liquid injection, exhaust/vacuum, etc.
The common pelletizing mode is water strand pelletizing.
