Lubricating oil plays four main roles in modern industry: preventing mechanical surface wear; acting as a coolant or heat transfer medium; helping to seal the compression ring; sticking to the mechanical surface to keep the mechanical surface clean. Generally, various additives with a mass fraction of about 10% are added to industrial lubricants to improve the performance of the oil. Zinc dialkyl dithiophosphate (ZDDP) is widely used because of its good oxidation resistance and wear resistance. Zinc dialkyl dithiophosphate is a compound synthesized from alcohol, phosphorus pentasulfide, and zinc salt. It mainly depends on the role of zinc dialkyl dithiophosphate in preventing oxidation of lubricating oil and reducing mechanical wear.
Overview of zinc dialkyl dithiophosphate ZnDDP solution
Zinc dialkyl dithiophosphate (commonly known as ZnDDP) is a coordination compound developed in the 1940s. Its characteristic is the combination of zinc with the anion of dialkyl dithiophosphoric acid (such as diethyl dithiophosphoric acid). These uncharged compounds are not salts. They are soluble in non-polar solvents, and long-chain derivatives are soluble in mineral synthetic oils used as lubricants.
Application of zinc dialkyl dithiophosphate ZnDDP liquid
The main application of ZDDP is as an anti-wear additive in lubricants, including grease, hydraulic oil and engine oil. ZDDP can also be used as a corrosion inhibitor and antioxidant. They are almost ubiquitous in lubricants, and the treatment rate is usually between 600 ppm for modern energy-saving low-viscosity oils to 2000 ppm for this additive in some racing oils.
According to reports, zinc and phosphorus emissions may damage the catalytic converter, and because the API limits the concentration of this additive in the new API SM and SN oils, the standard formulation of gasoline engine lubricants now reduces the amount of additives; however, this is only Affects grade 20 and 30 "ILSAC" oils. There is no regulation on ZDDP concentration for grade 40 and higher, but the zddp level of diesel that meets API CJ-4 specification is slightly reduced, although most diesel heavy-duty engine oils still have a higher concentration of this additive. ZDDP reduced crankshaft Tank oil is believed to cause damage or failure of classic/collector car flat pin camshafts and tappets on their contact surfaces and other areas such as main bearings, piston rings and pins. Roller camshafts/followers are more commonly used to reduce camshaft lobe friction in modern engines. There are additives, such as STP(R) oil treatment, and some racing oils, such as PurOl, PennGrade 1 and Valvoline VR-1, Kixx hydraulic oil, which are available in the retail market and contain the necessary amount of ZDDP. Engines that use increased valve spring pressure.
