双螺杆挤出机生产涂覆级聚丙烯的工艺优化改进

Optimization and improvement of process for coating grade PP production using twin-screw extruder

对双螺杆挤出机实施喂料系统改造,将单喂料系统改为双喂料系统。结果表明,对喂料系统改造后能够满足实际生产需要,所生产涂覆级聚丙烯质量稳定、性能优异。在满足生产工艺要求的前提下,不但优化了涂覆级聚丙烯生产工艺流程,简化了生产过程控制,而且减少了能源消耗,具有较好的经济效益。

Improvement was made to the feeding system of the twin-screw extruder,which changed the single feeding system intothe double feeding system.The result showed that,the improved feeding system can meet the requirement of practical production,the quality of the coating grade PP produced is stable,and the performance of it is excellent.Under the premise of meeting theproduction process requirement,the improvement not only optimized the production process flow of the coating grade PP,simplifiedproduction process control,but also reduced energy consumption,had better economic benefit.
