一、前言硅酸盐是一种使用方便、来源丰富、价廉、无毒的水质缓蚀剂。由于在使用过程中易产生硅酸镁、硅酸钙等硅垢,因此在应用上受到一定的限制。近年来,由于环境保护的要求日趋严格,铬系和磷系水处理剂的使用受到限制。同时,随着高效阻垢剂(如有机羧酸盐、有机膦酸盐等)的出现;使用硅酸盐作为冷却水系统的缓蚀剂又引起了人们的 First, the preface Silicate is a convenient, rich source, inexpensive, non-toxic water quality corrosion inhibitor. As in the use of easy to produce magnesium silicate, calcium silicate and other silica scale, so in the application of certain restrictions. In recent years, due to the increasingly stringent environmental protection requirements, the use of chromium-based and phosphorus-based water treatment agents is limited. At the same time, with the advent of efficient scale inhibitors (such as organic carboxylates, organic phosphonates, etc.), the use of silicates as corrosion inhibitors in cooling water systems has caused the
