The spraying line is composed of the processes of on-line, drying, shielding, leveling, drying, and off-line. The most important process in the spraying line is that some pollution is generated during the spraying process, such as exhaust gas, waste water, and waste residue.

According to professionals in the spraying line, if you want to solve the problem of exhaust gas, you must use pollution-free paint at the beginning, and paint that does not contain organic solvents. If there is no substitute for organic solvent coatings, only organic solvent-containing coatings can be used. The waste gas generated by organic solvents in the spraying line needs to be treated centrally. After the treatment is completed, it can be diluted before being discharged into the atmosphere.

It is understood that the exhaust gas generated in this drying furnace is generally combustible, so it is treated by combustion, and the gas produced by combustion and unburned gas can be adsorbed by activated carbon. The second is to reduce the generation of exhaust gas and generate dust during the grinding process. In order to control the amount of dust during the spraying process, the grinding, wiping process and painting process should be separated, and each process should have a workshop. In this way, dust can be prevented from entering the spraying room and drying oven, thereby eliminating the influence of dust on spraying.
