常温下低密聚乙烯的湍流超细粉碎研究

Ultra-fine comminution of LDPE with turbulence milling at atmospheric temperature

在湍流粉碎机上,进行了常温低密聚乙烯超细粉碎的转速、入料粒度和入料速度的实验.实验结果表明,在适宜的工艺条件下,湍流粉碎机对低密聚乙烯进行常温超细粉碎可以达到D50<6μm.同时,分析了低密聚乙烯在湍流场中得以超细粉碎的原因.

Experiment on ultra-fine LDPE comminution at atmospheric temperature was carried out on a turbulence mill to determine the feed＇s grain size, feeding rate, and milling speed. The experimental result showed that the comminution with grain size of D50〈6μm could be realized with an appropriate processing condition. In the meantime, the cause of ultra-fine comminution of LDPE with turbulence mill at atmospheric temperature was analyzed, also.
