Lube oil purifier is an indispensable additive in various internal combustion engine oils, which is a colloidal dispersion system formed by surfactant dissolved in diluted oil and a large number of nanoparticles (usually inorganic alkaline compounds). The surfactant in the dispersion system has the functions of colloid solubility, solubilization and clean dispersion, which can inhibit the serious pollution caused by incomplete combustion of fuel and oxidation of lubricating oil in internal combustion engines; the alkaline nano-magnesium carbonate component can effectively neutralize the harmful inorganic and organic acids generated by fuel and lubricating oil in the process of use, slow down the oxidation process of oil, reduce the corrosion and wear of engine, and prolong the service life of oil and engine.
The metal carbonates in the gel nuclei that provide the alkaline reservoir should be nanoscale, says Hebei Messi Biology Co. Many of the nanopowders, especially those of inorganic salts and metal oxides, are highly prone to agglomeration into clusters due to the huge surface energy, which in turn affects the application performance. The use of surfactant modification to reduce the surface energy is an important means to inhibit the aggregation of magnesium carbonate nanopowders. The nano magnesium carbonate for lube oil purifying and dispersing agent has good colloidal stability, purifying and dispersing properties with thermal oxidation stability.
Because the metallicity of magnesium is weaker than calcium, the carbonation process of nano-magnesium carbonate is more difficult than calcium salt in the preparation of lube oil clean dispersant, and the...
