Abstract

The invention discloses a preparation method for an efficient corrosion and scale inhibitor and belongs to the field of water treatment. The corrosion and scale inhibitor consists of polyaspartic acid, sodium silicate, phthalic diglycol diacrylate, poly(dimethyl-diallylammonium chloride), hexamethylenetetramine, bis(hydroxymethyl) imidazolidinyl urea, methylisothiazolinone, trehalose, tris(hydroxymethyl)aminomethane and water. The efficient corrosion and scale inhibitor is finally obtained through reasonably designing the mixing order of all the substances and controlling the temperature, agitating speed, agitating time and other conditions in the preparing process. The corrosion and scale inhibitor has the advantages of being good in corrosion inhibiting effect, capable of being stored for a long time, safe and environment-friendly in components, free of environment pollution and the like. The preparation method is simple, reasonable in design and easy to prepare, and has a good application prospects.

Description

technical field [0001] The invention belongs to the field of water treatment, and more specifically relates to a preparation method of 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 treat...
