提高摩擦橡胶的耐磨性,对增加橡胶摩擦密封件的寿命有着重要的意义。在乙丙胶内添加一定比例的氮化硅可以提高它的耐磨性(表1),以该胶料制成的高速旋转轴密封——油封,在应用过程中效果显著。
Improve the friction rubber wear resistance, to increase the life of the rubber friction seal is of great significance. The addition of a certain proportion of silicon nitride to ethylene-propylene rubber improves its wear resistance (Table 1). The high-speed rotary shaft seal-oil seal made of this compound shows remarkable results in application.
