对于处在高温(150～280℃)的机械运动副润滑油虽已作了种种努力,但在实际应用中,仍然存在着润滑性差、热挥发性大和结焦多等缺点,为此上海中华化工厂研制了SL-303合成高温润滑油,它基本上解决了机械运动副在高温工作时的润滑问题。使用效果 SL-303合成高温润滑油经上海第一印染厂、 Although the efforts have been made on the lubricating oil of mechanical movement at high temperature (150 ~ 280 ℃), in practical applications, there are still some shortcomings such as poor lubricity, large thermal volatility and coking. Therefore, Shanghai Zhonghua Chemical Plant Developed SL-303 synthetic high-temperature lubricating oil, which basically solves the mechanical movement of the work in high temperature lubrication problems. Use effect SL-303 synthetic high-temperature lubricants by the Shanghai first printing and dyeing plant,
