聚乙烯塑料性能特点及其注塑工艺详解

Performance characteristics of polyethylene plastics and its injection molding process

聚乙烯为典型的热塑性塑料,是无臭、无味、无毒,手感似蜡的可燃性白色粉末。成型加工的PE树脂均是经挤出造粒的蜡状颗粒料,外观呈乳白色。具有优良的耐低温性能,化学稳定性好,能耐大多数酸碱的侵蚀。根据聚乙烯塑料的结构性能,分析了聚乙烯塑料的类型特点,介绍了线性低密度聚乙烯塑料性能、注塑工艺及其应用,研究了高密度聚乙烯塑料性能、注塑工艺及其应用,指出了聚乙烯塑料的产业发展及市场前景。

polyethylene as typical thermoplastic plastics, is odorless, tasteless, non-toxic, feel like wax flammable white powder. PE resin molding is the wax granule extrusion granulation, milky white appearance. It has excellent resistance to low temperature performance, good chemical stability, erosion resistance to most acid and alkali. According to the structure properties of polyethylene plastic, analyzes the types and characteristics of polyethylene, introduces the properties of linear low density polyethylene plastic injection molding process, and its application on the properties of high density polyethylene plastic injection process and its application, points out the industry development and market prospect of polyethylene plastic.
