1、聚四氟乙烯与亲油性纤维混合物0.01-0.03mm 2、球形青铜粉0.2-0.3mm 3、不锈钢背0.7-2.3mm |
最大承载压力: | 140N/mm2 | 适用温度范围: | -195~+280摄氏度 | 最高滑动速度: | 2m/s |
摩擦系数: | 0.04~0.20 | 允许最高PV值(干): | 3.6N/mm2 .m/s | 允许最高PV值(油): | 50N/mm2 .m/s |
1.PTFE、亲油性纤维的混合物在运动时可形成很好的转移膜保护对磨轴。
2.耐磨性能好,磨擦系数低。
3.走合性能好,无咬轴现象。
4.可运用于旋转、摇摆、往复运动之中。
5.耐腐蚀性能好。
6.由于不含铅,故可运用于食品机械、医疗机械等绿色环保设备。
7.典型用途:主要运用于中酸、强碱场合,例如:化工中酸碱流量计、泵、阀,印染机械、 海洋工业耐腐蚀滑动部位。
