过去10年间,在切削液的生产中,水溶性切削液约占30％。近来,随着无人化加工的推广和环保条件的提高,水溶性切削液的使用量还将进一步增长。 微生物对水溶性切削液的影响极大。它将使切削液的化学性质发生变化,进而影响其润滑性能,并造成工件、刀具、机床受到腐蚀,既影响加工精度,又有损工人健康。 控制微生物的增多,通常均采用杀菌剂进行处理,近来正在研究用紫外线照射杀菌等方法,但主要是采用杀菌剂。杀菌剂可在切削液使用前添加,也可在使用后添加。 In the past 10 years, the production of cutting fluid, water-soluble cutting fluid accounts for about 30%. Recently, with the promotion of unmanned processing and environmental conditions, the use of water-soluble cutting fluid will further increase. Micro-organisms have a great influence on water-soluble cutting fluids. It will change the chemical properties of the cutting fluid, thereby affecting its lubricating properties, and cause corrosion of workpieces, knives and machine tools, both affect the processing accuracy, but also damage the health of workers. Increased control of microorganisms, are usually used biocides for processing, recently been studied with UV irradiation sterilization and other methods, but mainly the use of fungicides. Bactericide can be added before the cutting fluid can also be added after use.
