Description

technical field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a green and environment-friendly composite corrosion and scale inhibitor for circulating cooling water treatment. Background technique

[0002] Although circulating cooling water treatment technology is a technology developed to solve environmental problems, it has played a very important role in saving water, saving energy and reducing consumption, ensuring the safe and stable operation of industrial production equipment, and solving the global problem of water resource depletion, but at the same time The use of circulating water treatment chemicals also has a certain impact on the environment.

[0003] As early as the early 1930s, inorganic polyphosphates such as sodium tripolyphosphate and sodium hexametaphosphate were used to solve the problems of scaling, clogging and corrosion in urban water supply systems, but the effects of scale and corrosion...
