Causes of black air compressor oil: air compressor lubricants decline mechanism
1. oxidation: air compressor lubricants at high temperatures and metal catalyst and air and oxidation reaction of nitrogen oxides and sulfides, alcohols, aldehydes, ketones, acids, and oxygen-containing insoluble;
2. decomposing: breaking long-chain hydrocarbons at high temperatures into smaller molecules of hydrocarbon and gas;
3. the emulsion: because of the inhaled air contains water, which cannot be mixed together, "oil" and "water" the two liquids are mixed together, and has not been replaced a long time under oil, a liquid dispersed into many particles dispersed in a liquid, milk, emulsified oil lubrication effect reduced.
