Abstract

The present invention belongs to the field of circular cooling water treating technology, and is especially one kind of low phosphate green composite corrosion and scale inhibitor for treating circular cooling water and its usage. The green composite corrosion and scale inhibitor is compounded with polyepoxy sodium succinate, polysodium asparate, polymaleic acid, organic phosphonic acid, imidazoline type corrosion inhibitor, sodium gluconate, zinc salt and other antiscaling dispersant and corrosion inhibitor. When it is used, the green composite corrosion and scale inhibitor is added directly into circular cooling water. The green composite corrosion and scale inhibitor features its low phosphate content, biodegradability and environment friendship.

Description

technical field

[0001] The invention belongs to the technical field of circulating cooling water treatment, and in particular relates to a low-phosphorus environment-friendly water composite scale inhibitor for treating circulating cooling water and a use method thereof. 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, and solving the global water resource depletion problem, but at the same time, in the process of using circulating water treatment chemicals It also has some impact on the environment.

[0003] The traditional phosphorus-containing corrosion and scale inhibitors sodium tripolyphosphate and sodium hexametaphosphate are used in high concentrations, and their phosphorus content is greater than 30mg / L, which can cause serious eutrophication of water bodies and cause great damage...
