1、聚四氟乙烯與親油性纖維混合物0.01-0.03mm 2、球形青銅粉0.2-0.3mm 3、不銹鋼背0.7-2.3mm |
最大承載壓力: | 140N/mm2 | 適用溫度范圍: | -195~+280攝氏度 | 最高滑動速度: | 2m/s |
摩擦系數(shù): | 0.04~0.20 | 允許最高PV值(干): | 3.6N/mm2 .m/s | 允許最高PV值(油): | 50N/mm2 .m/s |
1.PTFE、親油性纖維的混合物在運動時可形成很好的轉(zhuǎn)移膜保護對磨軸。
2.耐磨性能好,磨擦系數(shù)低。
3.走合性能好,無咬軸現(xiàn)象。
4.可運用于旋轉(zhuǎn)、搖擺、往復運動之中。
5.耐腐蝕性能好。
6.由于不含鉛,故可運用于食品機械、醫(yī)療機械等綠色環(huán)保設備。
7.典型用途:主要運用于中酸、強堿場合,例如:化工中酸堿流量計、泵、閥,印染機械、 海洋工業(yè)耐腐蝕滑動部位。
