一、前言防土金属腐蚀有许多方法。其中之一是向引起金属腐蚀的介质中添加少量物质抑制金属腐蚀的方法。这种物质在广义上被称作抑制剂。它们有消极的与积极的两种,前者是除掉腐蚀性物质,其中有亚硫酸盐、联氨脱氧剂等。后者是通过在金属表面上发生反应而抑制腐蚀,一般将这种物质叫作抑制剂,这类抑制剂有许多种按着不同的观点进行分类有以下几种。 I. Preface There are many ways to prevent soil erosion. One of these is a method of adding a small amount of a substance to a medium that causes metal corrosion to suppress metal corrosion. This substance is broadly described as an inhibitor. They have two negative and positive, the former is to get rid of corrosive substances, including sulfites, hydrazine deoxidation agent. The latter, which suppresses corrosion by reacting on the metal surface, is commonly referred to as an inhibitor. There are many types of such inhibitors that are classified according to different perspectives as follows.
