Problems solved by technology

The paint mist formed by overspray paint will adhere to the walls of the water tank and pipes along with the flow of the circulating water system. The adhered paint is very viscous and difficult to handle
If these paint mist cannot be treated in time, a large paint mass will be formed to block the pipeline, affecting the working efficiency of the circulating water treatment system

Abstract

The invention discloses a paint mist coagulant, which is prepared from the following components: a paint mist flocculant, a paint flocculant, a paint remover, a sterilizing agent, a defoamer, a pH regulator and water, the dosage ratio of the paint mist flocculant, the paint flocculant, the paint remover, the sterilizing agent, the defoamer, and water in parts by mass is (1.0-2.0):(0.5-1.5):(0.4-0.8):(0.05-0.10):(0.2-0.5):1000, the dosage of the pH regulator is the amount for regulating the system's pH to be 7-10, the paint mist coagulant has the effect of treating paint mist in paint sprayingrooms.

Description

technical field [0001] The invention relates to waste gas treatment technology in a painting environment, in particular to a paint mist coagulant. Background technique [0002] With the development of the painting process of modern spray booths, while the process is constantly being updated, the overspray paint formed during the spraying process has always been a problem in the treatment of circulating water in spray booths. The paint mist formed by overspray paint will adhere to the walls of the water tank and pipes along with the flow of the circulating water system. The attached paint is difficult to handle due to its high viscosity. If the paint mist cannot be treated in time, a large paint mass will be formed to block the pipeline, which will affect the working efficiency of the circulating water treatment system. Contents of the invention [0003] The object of the present invention is to provide a paint mist coagulant, which solves the problem of processing the pai...
