Description

technical field [0001] The invention belongs to the field of water treatment, and more specifically relates to a high-efficiency corrosion and scale inhibitor. Background technique [0002] Due to the increasing shortage of fresh water resources, more and more people pay more and more attention to circulating cooling water treatment chemicals in the industry. The circulating cooling water is accompanied by the whole process of production, accounting for 70-80% of the total water consumption. The circulating cooling water is constantly used in the process of use. Evaporation and concentration make the scaling and corrosion of the cooling water pipe more serious, and it is easy to breed bacteria and algae, which affects the heat transfer effect of the equipment and shortens the service life of the equipment. In order to solve these problems, the circulating cooling water must be treated for water quality. Organic phosphonic acid is a type of water treatment agent widely used a...
