What are the oil additives?
Petroleum Additive (Petroleum Product Additive), a certain amount of added to the base oil, can enhance or give people hope that some of the properties of chemicals. Such as mineral oil in the humidity box in the anti-rust ability is only 4h or so, plus anti-rust agent rust inhibitor oil, anti-rust ability up to hundreds of hours; base oil and water can not be miscible, but in the oil by adding emulsification Agent, you can make oil and water to produce a stable emulsion. Additives is one of the important means to improve the quality of oil and increase the variety of oil. It is worth mentioning that the additive is not a panacea, it can not make inferior oil into high-quality oil, additives is only one of the main factors to improve the quality of oil. The contribution of the additive depends not only on its particular composition but also on the quality of the base oil (ie, the base oil has a certain degree of refinement or type, ie solvent refining, hydrofinishing, wax isomerization or synthetic oil) and Add the oil additive formula technology, the two are indispensable.
Extreme pressure agent (Extreme Pressure Agent or EP Additive), in extreme pressure conditions to prevent sliding metal surface sintering and abrasion of chemicals. Such as: T321 vulcanized isobutylene and so on.
Antioxidant and Corrosion Inhibitor (Oxidation-Corrosion Inhibitor), can inhibit oil oxidation and protection of lubricating surface from water or other pollutants chemical erosion of chemicals. Such as: T202 thiophosphate butyl ether alkyl zinc salt, T203 thiophosphoric acid and zinc salt, T204 phosphorothioate, A secondary alkyl zinc salt, and a T207 thiophosphoric acid.
Dispersant A chemical that allows solid contaminants to be suspended in the colloidal state to prevent sludge, paint, and sludge from depositing substances on the engine parts. Dispersants are usually non-metallic (ashless) and are generally used in combination with detergents. Such as: T154A polyisobutenyl succinimide, T154B boronized polyisobutenyl succinimide, T161A high molecular weight polyisobutenyl succinimide, T161B boronated high molecular weight polyisobutenyl succinimide, T151A polyisobutenyl succinimide, T164A high molecular weight polyisobutenyl succinimide, T165A high molecular weight polyisobutenyl succinimide.
Detergent, added to the fuel or lubricant can make the engine parts to be cleaned and keep the engine parts clean chemicals. In the engine oil formula, the detergent is mostly alkaline metal soap to neutralize the oxidation or combustion of acid generated. (TBN300), long-chain linear alkylphenyl high-alkali synthesis of calcium sulfonate (TBN400), long-chain linear alkylated benzene, , High base value sulfide alkylphenol calcium, long chain linear alkyl benzene high base value synthesis of magnesium sulfonate.
