 工程塑料合金是以不同单体共聚的高分子为基础,采用合成的稀土纳米材料及多种添加剂改性,通过特殊的合成工艺制造而成的均质聚合物,具有出色的摩擦系数低、自润滑免维护、耐腐蚀、耐磨损、承载力大、抗老化等特性,产品对偶工作面在三态(干态,水态,油态)工况下摩擦系数变化小,而且各态动静摩擦系数相差小。材料在三场(力场、电场、化学场)作用下的机械性能稳定。

产品使用与设计说明
 MGA
材料多用于特殊工况,主要用于军品或重要特殊场合。
 MGB
材料多用于大型重载、有腐蚀不易加油或重大型水利工程项目的工况。如弧门支铰轴承,大载荷滑轮轴承、止推轴承、关节轴承、滑板、闸门滑块、人字门支撑轴承、水轮机导叶轴承等。
MGC
材料主要应用在一些大中型载荷的轴承、滑板或滑块、止推环等。
MGD
材料主要应用在一些中小型载荷的轴承、滑板或滑块、止推环等。 MGE 材料用于坞门承压垫、桥墩防撞板、材料摩擦系数低,动静摩擦系数相近,可用于平移大型重物的滑板。 MGE 材料用于钢丝绳铰轮、托辊、齿轮、定位轮、行走轮等。
MGC
滑板不仅应用于船舶下水滑道,而且在桥梁建设,顶推装置等工程应用广泛。

自润滑工程塑料合金MGA材料具有很好的性能,所以才被广泛的应用,您可以参考数据对比,相信定会有自己的结论
