Technical Field
The invention relates to the technical field of environmental engineering, in particular to a paint dust treating agent and application thereof.
Background
A large amount of paint dust is generated in the process of paint spraying and polishing furniture, and the paint dust is small, high in viscosity and easy to adhere to the surface of a substance.
Most of paint dust is below 10 mu m, and if untreated, activated carbon adsorption quickly blocks activated carbon micropores, so that the activated carbon fails.
When the paint dust is subjected to dry filtering treatment by physical interception such as filtering, the paint dust is often prevented from being used due to the adhesion of the paint dust to equipment.
When wet treatment is carried out on paint dust by adopting a water washing type paint spraying chamber or a spray tower, the purification efficiency is low, the pretreatment requirement cannot be met, and the used packing spray tower is easy to block, the resistance is large, and the stable operation cannot be realized.
Disclosure of Invention
The problems in the prior art are that: when wet treatment is carried out on paint dust by adopting a water washing type paint spraying chamber or a spray tower, the purification efficiency is low. In order to solve the problems, the invention provides a paint dust treating agent which comprises the following components in percentage by mass:
specifically, the dispersant is a water-oil amphoteric dispersant.
Specifically, the water-oil amphoteric dispersant comprises Digadispers 655 and Basff dispersant
At least one of Ultra FA 4420.
Specifically, the mildew preventive is a water-based mildew preventive, and the water-based mildew preventive is a water-based mildew preventive JL-1289.
Specifically, the defoaming agent is a water-based silicone defoaming agent.
Specifically, the aqueous silicone defoamer comprises BYK chemical BYK-024.
Specifically, the wetting agent is a nonionic surfactant.
Specifically, the nonionic surfactant is an acetylenic diol Germini nonionic surfactant, U.S. gas chemical Surfynol104BC.
Specifically, the paint dust treating agent can be added into a spraying aqueous solution used in a water-washing type spray booth or a spraying cabinet, and paint dust is wetted, adsorbed and settled in the spraying process.
Advantageous effects
The inventor finds that different types of wetting dispersants or high molecular dispersants are applied to the paint through a large number of experimentsThe wetting, adsorption and sedimentation efficiency of dust are greatly influenced, the water-oil amphoteric polymer dispersant has better hydrophilic dispersion stability on paint dust, and DigaDispers 655 dispersant or Pasteur dispersant in the water-oil amphoteric polymer dispersant
The Ultra FA 4420 is particularly outstanding in performance, can remarkably enhance the lyophilic property of the paint dust surface, and forms stronger charge action or steric hindrance effect on the paint dust surface, so that the paint dust dispersion is more stable in dispersion; in addition, compared with other types of surfactants, the nonionic surfactant has better wetting and adsorption effects on paint dust, and particularly, the American gas chemical Surfynol104BC in the acetylenic diol Germini nonionic surfactant can better purify the working environment of a paint spray booth under the comprehensive effect of various components of the paint dust treating agent.
