Spray the powder coating on the surface of the workpiece with powder spraying equipment(electrostatic spraying machine), under electrostatic action, these powder will be absorbed on it evenly, form a powder coating; the powder coating is cured by high temperature baking and leveling, becoming a final coating with various effects(different kinds of effects for powder coatings). Atomized dust particles generated by liquid paint under the action of barometric pressure, which present viscous, very easy to stick to people or objects it touches, and is a potential carcinogen, pollute the entire atmosphere.
The exhaust gas containing organic matter passes through the action of the fan, through activated carbon adsorption layer, the organic matter is adsorbed in the micropores of activated carbon by utilizing the strong adsorption capacity of activated carbon with microporous, clean air is discharged; after a while, when activated carbon reaches saturation state, stop adsorption, at this point the organic matter has been concentrated in the activated carbon, and then use catalytic combustion for activated carbon to desorption and regeneration.
