Problems solved by technology

The separation of paint and water in circulating water requires the use of a circulating water purifier. However, in the prior art, the debonding effect of paint detackifier is not complete, the flocculation effect of paint floating agent is not good, the removal rate of paint slag is low, and the moisture content of paint slag is low. high, the color of sewage is difficult to completely remove, and the circulating water has a large odor, so improving the purification ability of circulating water purifiers is an urgent problem to be solved at present

Abstract

The invention discloses a coating circulating water purifying agent. The purifier comprises an agent A and an agent B, wherein the agent A is prepared from components in parts by weight as follows: 1.5-2.5 parts of sodium bentonite, 0.2-0.5 parts of chitosan, 0.5-1 part of a surfactant, 1.5-2.5 parts of a penetrating agent, 2-3 parts of a dispersant, 1-2 parts of a preservative, 0.5-1 part of an antifoaming agent and 87.5-92.8 parts of water; the agent B is prepared from components in parts by weight as follows: 0.2-0.4 parts of cationic polyacrylamide, 0.1-0.2 parts of a citric acid aqueous solution, 1-2 parts of an aluminum sulfate aqueous solution, 0.7-1 part of an ammonium bicarbonate aqueous solution and 96.4-98 parts of water. The coating circulating water purifying agent has the advantages of being good in paint debonding effect, good in flocculation effect, high in paint slag removal rate, low in paint slag moisture content, capable of completely removing foreign colors of water and inhibiting foreign odors of circulating water and the like.

Description

technical field [0001] The invention belongs to the technical field of industrial coating circulating water treatment, and in particular relates to a coating circulating water purifier, a preparation method and a use method thereof. Background technique [0002] In industries such as automobiles, hardware, machinery, home appliances, kitchen utensils, aluminum veneer profiles, furniture, and daily necessities, there are painting processes. During the painting process, the paint is not all sprayed on the workpiece, and the part of the paint that is not sprayed on the workpiece is called overspray. The oversprayed paint is taken away by the air. In order to prevent the paint mist from being discharged into the atmosphere and pollute the environment, circulating water is generally used in the spray booth to capture the oversprayed paint mist in the air. With the accumulation of sprayed paint, the concentration of paint in the circulating water will increase. The higher it is, ...
