摘要
在内燃机油中,金属清净剂胶体的稳定性十分重要,其稳定性与胶体结构有关。无灰分散剂在一定程度上可以提高金属清净剂的稳定性,胶溶剂和助表面活性剂也可以提高金属清净剂胶体的稳定性。金属清净剂胶体越小,稳定性越好。通过研究金属清净剂胶体稳定性与胶体结构的关系,可为新型金属清净剂的开发提供参考。对近年来金属清净剂胶体稳定性与胶体结构的研究进展进行了综述。
In the engine oils, the colloidal stability of the metal detergent was very important, and its colloidal stability was related to the colloidal structure. Ashless dispersant could improve the stability of metal detergents.Colloidal solvent and auxiliary surfactants could also improve the colloidal stability of metal detergents.The smaller the metal detergents colloid was, the better the stability would be. By studying the relationship between the colloidal stability of metal detergents and the colloidal structure, it could provide reference for the development of new metal detergents. The research progress of colloidal stability and colloidal structure of metal detergents in recent years was reviewed.
