1. Air compressor oil composition lubricant base oil
Lubricant base oil is mainly divided into two categories: mineral base oil and synthetic base oil. Mineral base oil is widely used and used in large quantities, but some applications must use products formulated with synthetic base oil, which has led to the rapid development of synthetic base oil.
Mineral base oil is refined from crude oil. The main production processes of air compressor oil composition lubricant base oil are: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, kaolin or hydrogenation supplementary refining.
The chemical composition of mineral base oil includes high boiling point, high molecular weight hydrocarbons and non-hydrocarbon mixtures. The composition of air compressor oil is generally composed of alkanes, cycloalkanes, aromatics, cycloalkyl aromatics, oxygen-containing, nitrogen-containing, sulfur-containing organic compounds and non-hydrocarbon compounds such as colloids and asphaltene.
2. Air compressor oil component additives
Additives are the essence of modern advanced lubricants. Correct selection and reasonable addition can improve its physical and chemical properties, give new special properties to lubricants, or enhance certain properties of air compressor oil components to meet higher requirements. Careful selection, careful balance and reasonable deployment of additives according to the quality and performance requirements of lubricants are the key to ensuring the quality of lubricants. Commonly used additives for air compressor oil components are: viscosity index improvers, pour point depressants, antioxidants, detergents and dispersants, friction modifiers, oiliness agents, extreme pressure agents, anti-foaming agents, metal passivators, emulsifiers, corrosion inhibitors, rust inhibitors, and demulsifiers.
