The application of magnesium carbonate in lubricating oil detergent dispersants is mainly reflected in the following aspects:
Detergent effect:
As a detergent, magnesium carbonate can inhibit the serious pollution caused by incomplete fuel combustion and lubricating oil oxidation in internal combustion engines.
Dispersing effect:
As a dispersant, magnesium carbonate can effectively neutralize the harmful inorganic and organic acids generated by fuel and lubricating oil under working conditions, reduce engine corrosion and wear, and extend the service life of oil products and engines.
Colloidal stability:
Magnesium carbonate has good cleaning dispersibility, colloidal stability and thermal oxidation stability when adding an appropriate amount of nano-magnesium carbonate to lubricating oil.
Preparation process:
When preparing the nano-magnesium carbonate oil-soluble dispersion system, a unique water addition method and carbon dioxide inflow rate are used to ensure that the generated magnesium carbonate can be evenly dispersed in the oil phase to form micelles, thereby ensuring the size of the micelles and the performance of the product.
In summary, the application of magnesium carbonate in lubricating oil detergent dispersants is mainly as a detergent and dispersant, which can neutralize harmful acids, reduce wear and corrosion, and improve the stability and thermal oxidation stability of oil products, thereby extending the service life of oil products and engines. The key to its preparation process is to ensure the uniform dispersion and colloidal stability of magnesium carbonate nanoparticles.
