选用一定粘度的深度精制组分油为基础油,通过对L-MHEC22号切削油所用极压剂、油性剂的研究,确定了切削油的合理配方。
2.
NLM rust preventive cutting oil was prepared by adding proper amount of rust preventive agent, oilness additive and extreme pressure additive into the base oil.
以炼油厂加氢裂化柴油为原料,通过常压蒸馏切割、加增粘剂和抗氧剂来提高闪点、粘度及氧化安定性,制得合格的基础油,然后添加适宜的防锈剂、油性剂、极压剂,制备了NLM 防锈切削油,考察了添加剂的最佳添加量和复合使用效果,并根据小试配方进行了试验室放大。
补充资料:切削油及切削速度
切削油剂有润滑、冷却及抗融著的三种作用,此称为切削油的三要素。攻牙的情形进行著非常复杂的切削作用,所以必须给予充分切削油以利其作业。 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
