Zinc dithiophosphate is used as an anti-wear and anti-corrosion additive in industrial lubricants, such as gear oils, hydraulic oils, and metalworking fluids.
Some common applications include motor oils, transmission fluids, and industrial fluids.
It provides lubrication, reduces friction and wear, and helps increase the lifespan of machinery and equipment.
It provides wear protection to engine components and helps extend the life of the lubricant.
It also prevents corrosive wear by forming a protective film on metallic surfaces, which reduces friction and helps prevent abrasion.
Here are some of the main uses and benefits of zinc dithiophosphate:
- Anti-wear protection: Zinc dithiophosphate forms a protective film on metal surfaces, reducing friction and wear in the engine. It helps to prevent metal-to-metal contact and prolong the life of engine components such as bearings, camshafts, and piston rings.
- Oxidation inhibition: This additive also provides oxidation resistance to the lubricant, preventing the degradation of the oil due to high operating temperatures and oxidative stresses. It helps to maintain the viscosity and thermal stability of the oil.
- Corrosion prevention: Zinc dithiophosphate contains zinc, which provides corrosion protection to metal surfaces. It helps to prevent the rusting and corrosion of engine components, particularly in the presence of moisture and acidic contaminants.
- Detergency: Zinc dithiophosphate also has detergent properties, helping to keep the engine clean by dispersing and suspending contaminants and deposits. It prevents the formation of sludge, varnish, and carbon deposits, ensuring proper lubrication and prolonging the life of the engine.
Overall, zinc dithiophosphate plays a crucial role in improving the performance and longevity of lubricants, particularly in automotive engine oils.
