What is motor oil analysis oil additive

When the temperature is not high, not heavy load conditions, the friction in the fluid lubrication, the lubricant film alone can reduce the friction coefficient, when the temperature, load and further improve the friction Deputy Commissioner in mixed - boundary lubrication , the strength is not enough to maintain the oil film lubrication, and then added to lubricating oil additives, oil additives by the strong absorption of activists and a low coefficient of friction non-polar molecules, of which the polar compound adsorbed on the metal surface , low coefficient of friction of the non-polar molecules outwardly to make contact with the metal contacts into the non-polar molecules, into good lubrication, thereby reducing friction and wear. These oiliness agents include fatty acids, fatty sulfur, phosphorus compounds and the polyol fatty lipids. When the load temperature increase friction in the boundary friction state, physical oily agent adsorbed film could not withstand the active elements and the chemical reaction of the metal membrane to maintain normal lubrication extreme pressure against Germany.
