Abstract

The invention belongs to the technical field of industrial circulating cooling water treatment, and particularly relates to a neutral calcium scale inhibitor and cleaning agent for a circulating water system. Specifically, the present invention contains complex scale remover, set retarding stabilizer, scale inhibitor and dispersant, and the rest is pure water. The neutral calcium scale inhibitor cleaning agent is neutral and suitable for circulating cooling water of any water temperature. Laboratory equipment metal base.

Description

technical field [0001] The invention belongs to the technical field of industrial circulating cooling water treatment, and in particular relates to a neutral calcium scale inhibitor and cleaning agent for a circulating water system. Background technique [0002] In the industrial production of daily boiler water, cooling circulating water and seawater desalination, due to the continuous heating and cooling circulation and concentration, the minerals in the water are precipitated, which will cause scaling of equipment pipes. The accumulation of scale layer not only affects heat transfer efficiency, causes heat loss, reduces efficiency, and increases production costs, but also corrodes equipment, shortens equipment service life, and endangers safe production. Therefore, the fouling layer must be treated regularly. Common types of scale are carbonate scale, sulfate scale, silicate scale, mixed scale, iron oxide scale, oil scale, etc. [0003] Among them, the calcium scale is ...
