酸洗过程中氨基酸类缓蚀剂缓蚀机理研究进展

Studies on the inhibition Mechanism of Amino acid Inhibiters in the process of Acid Cleaning

传统缓蚀剂,因其不可生物降解,从而导致环境问题。氨基酸类缓蚀剂是目前颇具前景的环境友好型绿色缓蚀剂。氨基酸是蛋白质的基本构成物质,由于它具有小分子结构,从而稳定性非常好,并且可广泛应用于酸性介质、中性介质及大气腐蚀介质中。本文首先综述氨基酸的种类和国内外氨基酸类酸洗缓蚀剂的研究状况;其次,从结构上对缓蚀剂与钢质管道所起作用作一机理方面探讨。

The traditional inhibitor may not biodegrade, thus causes the environ-ment questions. Amino acid inhibitor is environment friendly green inhibitor which has wide application prospect at present. Amino acid is the basic composing substance of protein. Because of the small molecule structure, the stability of amino-acid is very good, and it can utilize in acidity, neuter and atmosphere medium. At first, species and the international and national present state of the research on amino acid inhibitors are summarized; secondly, this paper discusses the mechanism between inh-ibitors and the steel pipes.
