(1) Detergent dispersants have four functions: solubilization, dispersion, acid neutralization, and adsorption.

(2) The function of anti-oxidant and anti-oxidant and anti-corrosion additives is to inhibit the oxidation process of oil products, passivate the catalytic effect of metals on oxidation, and achieve the purpose of prolonging the use of oil products and protecting machines.

(3) The role of the pour point depressant is to reduce the freezing point of the oil, so that the oil maintains good fluidity at low temperature and improves the low temperature starting performance of the engine.

(4) The viscosity index improver can increase the viscosity of oil products, especially to meet the low temperature performance requirements of oil products.

(5) The oily agent and extreme pressure anti-wear agent can react chemically with the metal surface to form a chemical reaction film to prevent wear, abrasion and fusion welding of the metal surface.

(6) The role of the anti-rust agent includes forming an adsorption protective layer on the metal surface, preventing the corrosive medium from contacting the metal, and playing a role of anti-rust.

(7) The main function of the anti-foaming agent is to inhibit the generation of foam, so as to avoid the formation of stable foam.

(8) The anti-emulsifier can change the tension of the oil/water interface, separate the oil and water, and achieve the purpose of improving the anti-emulsification performance of the oil.
