目前在热加工中最常用的高温润滑剂(石墨加油脂)有很大缺点,一是操作时烟雾弥漫,污染环境,二是高温润滑性能差。由低熔点玻璃(系无毒的硼酸盐玻璃)和粘结剂组成的W-101高温润滑剂克服了上述缺点,而且安全无毒,使用方便。美国专利3140779详细介绍了系统的高温润滑性能和粘度特性,由于具有高的温度粘度、梯度(B_2O_3 100％,1.75℃/泊;B_2O_380％,SiO_220％,1.80℃/泊)比铅硼酸盐玻璃(O.6℃/泊)和钠硅玻璃(1.2℃/泊)都要好。我们据此
At present, the most commonly used high-temperature lubricant in thermal processing (graphite plus grease) has great shortcomings, first, the operation of the smoke diffuse, pollute the environment, the second is poor high-temperature lubrication. W-101 high-temperature lubricant consisting of low-melting glass (non-toxic borate glass) and binder overcomes the above shortcomings and is safe, nontoxic and easy to use. U.S. Patent 3,140,779 details the high-temperature lubrication properties and viscosity characteristics of the system. Because of its high temperature viscosity, graded (B203 100%, 1.75 ° C / po; B2O3 280%, SiO2_2%, 1.80 ° C / po) (0.6 ° C / poise) and soda-lime glass (1.2 ° C / poise). We accordingly accordingly
