缓蚀剂按作用机理分类可分为:阳极缓蚀剂、阴极缓蚀剂、吸附型缓蚀剂。其中吸附型缓蚀剂现在实际应用很多,防蚀作用虽然很早就进行研究,其机理已相当明确,但不足之处仍然不少。本文仅就吸附型中的酰胺类缓蚀剂有效防蚀基团作一论述。
Corrosion inhibitors classified according to the mechanism of action can be divided into: anode corrosion inhibitors, cathodic corrosion inhibitors, adsorption inhibitors. Among them, adsorption-type corrosion inhibitors are used in many practical applications. Although the anti-corrosion effect has been researched very early, the mechanism has been quite clear, but there are still many shortcomings. This article only on the adsorption type of amide inhibitors effective anti-corrosion group made a discussion.
