在切削加工中,细菌和霉菌能损坏乳化油,引起臭味,改变颜色,造成乳化液的破坏和酸度增加。在恶劣条件下,乳化液每隔几天就需更换。添加杀虫剂能够延长乳化液使用寿命,但它会伤害操作者的皮肤(接触皮炎和过敏性皮炎)。 Mobil化学公司最近研制出一种通用的乳化液,名称为Mobilment Aqua Rho。它不含杀虫剂,但仍能抑制微生物的生长。它的成分是含磷、氮和硼的合成物,不是含氯、硫的化合物或苯酚。用最少的搅拌次数、便能迅速生成乳化液。即使在冷水中,或且在硬水或去离子水中同样能很好地生成乳白色乳化液,对于20％的浓度是稳定的。
In cutting, bacteria and fungi can damage the emulsified oil, causing odor, changing color, causing emulsion damage and increased acidity. In harsh conditions, emulsions need to be replaced every few days. Adding pesticides can extend the life of the emulsion, but it can harm the operator’s skin (contact dermatitis and atopic dermatitis). Mobil Chemical recently developed a universal emulsion called Mobilment Aqua Rho. It contains no pesticides but still inhibits the growth of microorganisms. Its composition is phosphorus, nitrogen and boron compounds, not chlorine, sulfur compounds or phenol. With a minimum number of mixing, can quickly generate emulsion. Milky white emulsions are well formed in cold water or in hard or deionized water, and are stable at 20%.
