空压机油成分润滑油基础油
Air compressor oil composition lubricating oil base oil
润滑油基础油主要分矿物基础油及合成基础油两大类。矿物基础油应用广泛，用量很大，但有些应用场合则必须使用合成基础油调配的产品，因而使合成基础油得到迅速发展。矿油基础油由原油提炼而成。空压机油成分润滑油基础油主要生产过程有：常减压蒸馏、溶剂脱沥青、溶剂精制、溶剂脱蜡、白土或加氢补充精制。矿物基础油的化学成分包括高沸点、高分子量烃类和非烃类混合物。空压机油成分组成一般为烷烃、环烷烃、芳烃、环烷基芳烃以及含氧、含氮、含硫有机化合物和胶质、沥青质等非烃类化合物。
Lubricating oil base oil is mainly divided into mineral base oil and synthetic base oil. Mineral base oil is widely used and used in a large amount, but in some applications, the products prepared by synthetic base oil must be used, so synthetic base oil has developed rapidly. Mineral oil base oil is refined from crude oil. The main production processes of lubricating oil base oil of air compressor engine oil components include atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrorefining. The chemical composition of mineral base oil includes high boiling point, high molecular weight hydrocarbon and non hydrocarbon mixture. Air compressor oil is generally composed of alkanes, cycloalkanes, aromatics, cycloalkyl aromatics, oxygen-containing, nitrogen-containing and sulfur-containing organic compounds, colloids, asphaltenes and other non hydrocarbon compound
