Definition: Grease steel mesh oil separation refers to the tendency of base oil to separate from grease under heated conditions, indicating the quality of the grease’s colloidal stability when subjected to heat.

① Steel mesh oil separation is an important indicator of colloidal stability, which can predict changes in the structural framework of grease under heated conditions.

② The colloidal stability of grease refers to its ability to maintain a stable colloidal structure under heat and pressure, preventing the separation of base oil.
