　　classification standard

　　1. Classified by type: manual spray painting and automatic spray painting.

　　2. Classified by paint type: alkyd paint, acrylic paint, water-based paint.

　　The standard for spray painting can be divided into two different capacities of 200 and 400ml according to the volume (according to the European Paint USA company standard).

　　3. Divided by brightness into high gloss (also known as glossy), semi matte, and matte (also known as fully matte).

　　The primary use of active adsorption equipment is to filter and adsorb organic waste gas and dust in the exhaust gas, and then achieve the effect of purifying organic waste gas and dust removal. Adsorption equipment is a relatively traditional method of exhaust gas treatment, and many companies have been using this equipment in recent years.

　　Catalytic combustion is a purification method that uses catalysts to oxidize and decompose combustible substances in exhaust gas at lower temperatures. So, catalytic combustion is also known as catalytic chemical conversion. Due to the acceleration of the oxidation decomposition process by the catalyst, most hydrocarbons can be completely oxidized by the catalyst at temperatures of 300-450 ℃.

　　Compared with the thermal combustion method, catalytic combustion requires less auxiliary fuel, consumes less energy, and has smaller equipment and facilities. However, the promotion and application of this method in industrial production processes have been affected by issues such as catalyst poisoning, replacement of catalytic beds, and high cleaning costs.

　　Process principle and flow: Catalytic purification is a typical gas-solid phase catalytic reaction, which essentially involves deep oxidation with the participation of reactive oxygen species. In the process of catalytic purification, the role of the catalyst is to reduce the activation energy, and at the same time, the surface of the catalyst has adsorption, which enriches the reactant molecules on the surface and increases the reaction rate, accelerating the progress of the reaction. With the help of catalysts, organic waste gas can undergo flameless combustion at lower ignition temperatures, and be oxidized and decomposed into CO2 and H2O, while releasing a large amount of heat energy, thus achieving the method of removing harmful substances from the waste gas.
