列宁格勒金属加工厂采用了一种以聚乙烯酒精为基料的润滑冷却液,聚乙烯酒精溶液绝对无害,没有难闻的气味,这种冷却液可改善金属的切削条件,提高刃具的寿命。聚乙烯酒精水溶液是冷却和润滑介质。在溶液中含有聚乙烯溶液这种表面活性物质可以保证在金属表面上产生连续薄膜,它能很好散热,并且有很 The Leningrad metalworking plant uses a lubricant based on polythene alcohol, which is absolutely harmless and has no unpleasant odors. This coolant improves the cutting conditions of the metal and improves the cutting edge life. Polyethylene alcohol aqueous solution is a cooling and lubricating medium. Containing polyethylene solution in solution This surface active material ensures that a continuous film is produced on the metal surface and that it dissipates well and that there is a
