As of December 23, 2013, daqing lianhua company polypropylene plant 2 sets of polypropylene (PP) plant of continuous running smoothly after 11 days. Was provided to solve the problem of continuous operation of the extrusion granulator HP565S products.
Learned, HP565S is high melt index products, production of extrusion pelleting machine need to add a lot of liquid peroxide make powder rapid degradation in order to improve the melt index of the products. After liquid peroxide into the cylinder, if mixed with powder in the cylinder body not divide evenly, can cause uneven resin degradation, big swings in net pressure difference before and after extrusion machine, pad dao, tangle occur, production difficulty is great, directly affect the smooth running of extruding machine. Deputy director Wang Haiqing called technical research, and actively explore control powder and peroxide mixing uniformity in cylinder body. After repeated experiments, and finally by adjusting the rotational speed, change the add method and control the heating temperature and realized the smooth operation of the extruder.
