多种添加剂在汽车冷却液中的应用及作用机理

Application and Action Mechanism of Various Additives in The Auto Coolant

文章对多种添加剂的作用机理和应用方法进行了探讨。在汽车冷却液的制造过程中应用了大量的无机缓蚀剂和有机缓蚀剂,无机缓蚀剂的作用机理为金属阳离子缓蚀剂、阳极钝化型添加剂,特性吸附阴离子型缓蚀剂;有机缓蚀剂的作用机理大致归纳为吸附成膜机理和界面反应成膜机理。在选择添加剂中应考虑溶解性、对应性、相容性。

This paper explores the art ion mechanism and application method ol various coolant. In the manufacturing process of auto coolant, large amount of non - organic corrosion - inhibitor and organic corrosion - inhibitor are used. Action mechanism of non - organic corrosion - inhibitor is metal positive ion corrosion -inhibitor, anode passivation additive, characteristics absorbing negative ion corrosion - inhibitor; action mechanism of organic corrosion - inhibitor is summarized as absorbing filming mechanism and interface reaction filming mechanism. In selection of additives, solvability, correspondence and compatibility must be considered.
