The rapid development of industry has placed higher demands on water treatment technology, which has further promoted the development of water treatment chemicals. The 1960s and 70s were a period of great development for water treatment chemicals, with various chemicals experiencing their respective peak periods. During this time, numerous technological breakthroughs emerged, and the variety, quantity, and output all showed a significant upward trend. To effectively achieve corrosion inhibition, scale inhibition, and sterilization, and to better control pollution and public nuisance caused by wastewater discharge, new types of organic corrosion inhibitors, organic scale inhibitors, and organic bactericides were gradually developed and used. The upstream of the industrial water treatment chemicals industry mainly includes basic chemical raw materials, specialty chemicals, auxili...
