聚丙烯过氧化物浓缩母粒生产控制

Control of Production of PP Peroxide Concentrated Masterbatch

介绍聚丙烯过氧化物浓缩母粒的生产控制。研究了过氧化物注入口、加入方式对产品性能的影响。结果表明 ,过氧化物最佳注入口应选择在靠近口模处 ,加入方式可选择侧位重量加料器或高压计量泵系统 ,后者可通过压力表、过氧化物的递减量对生产过程进行控制。LS -10浓缩母料的熔体指数在 60 g/

s [WT5BZ]The control of the production of peroxide concentrated masterbatch is introduced.The effects of the throat for peroxide and feeding method on product property were studied.The results showed an optimum throat should be located near the die and peroxide could be fed in by means of weight batcher of high pressure metering pump system,which could control the production by means of pressure gauge and the decrease of peroxide.The melt index of LS-10 concentrated masterbatch was above 60g/10min.
