韶山1型电力机车用 TKH_3型转换开关传动气缸首先采用了国产聚氨基甲酸酯橡胶(简称聚酯橡胶)皮碗,深得制造、使用人员的欢迎。目前已推广使用到组合接触器、电空接触器、调压开关等产品上,由原来φ85直径气缸推广至φ45、φ55、φ100直径气缸上。聚酯橡胶外观为浓黄色半透明材料。我国进口6Y_2型电力机车上就使用过这种材料的皮碗,它特别好的耐磨性使它早负盛名。另外它有较好的强力与弹性,在很高硬度下仍能保持一定的伸长率,最高使用温度为+80℃,它还
Shaoshan 1 type electric locomotive TKH_3 type switch drive cylinder first used domestic polyurethane rubber (referred to as polyester rubber) cups, won the manufacturing, the use of staff welcome. Has now been promoting the use of combination of contactors, air-contactors, pressure switches and other products, from the original diameter φ85 diameter cylinder to φ45, φ55, φ100 diameter cylinder. Polyester rubber appearance of thick yellow translucent material. China imported 6Y_2 electric locomotive on the use of this material cup, it is particularly good wear resistance made it prestigious. In addition, it has better strength and flexibility, still maintain a certain elongation at very high hardness, the maximum operating temperature is +80 ℃, it also
