Composition and Hazards of the Exhaust Gas in the Auto Paint Industry

Nov 19, 2018

During the Auto spraying and painting process, the paint mist and organic waste gas are mainly polluted, and the paint is atomized into particles under the action of high pressure. When spraying, some of the paint does not reach the surface of the paint, and the airflow is dispersed in the air to form a paint mist; the organic waste gas is diluted. The volatilization of the agent, the organic solvent will not adhere to the surface of the paint with the paint, and will be completely released into the organic waste gas during the painting and curing process (there are hundreds of volatile organic compounds reported in the literature, belonging to alkanes, cycloalkanes, olefins, aromatics, respectively). Compounds, alcohols, aldehydes, esters, ethers and their compounds). The composition of spray paint and paint exhaust is mainly: “triphenyl” and volatile organic waste gas (VOCs) treatment.


The exhaust gas in the paint baking industry has a large amount of exhaust gas, a high concentration, and contains many kinds of organic substances. Generally, the exhaust gas of the paint industry contains organic substances such as triphenyl, alcohols, ketones, ethers, esters and the like. The exhaust gas in the paint baking industry contains many kinds of organic substances, among which the content of “triphenyl” is high and the damage is high. The benzene, toluene and xylene are colorless, have aromatic odor, and have a boiling point of 80 degrees. They are volatile organic compounds. They all have volatile and flammable properties. If it is directly discharged, it will pollute the air environment in life, and if it is not handled properly, it will easily cause fire. Therefore, it is recommended to equip the paint baking equipment with environmental protection equipment to treat the exhaust gas discharged and discharge it after meeting environmental safety standards.
