How to deal with the pollution problem of automatic spraying production line?

At present, the application of spraying robot equipment in the field of coating engineering in China is very common. Many automated spraying equipment have been produced. For example, many automobile manufacturers, the spray coating of car shells and engines are produced by automatic spraying production lines. Produced. Although the automatic spraying production line brings us a lot of convenience, it also brings a lot of harm to our environment. Let's discuss with you how to deal with the pollution problem of the automatic spraying production line.

The main sources of waste gas pollution in the automatic spraying production line are drying furnaces, pretreatment, paint spraying rooms, leveling rooms, etc. The main pollutants emitted include odorous paint volatile components, thermal decomposition products and dust pollution in paint mist, and Organic solvents that can form photochemical smog. In view of the above-mentioned pollutants, in the face of this situation, spraying equipment manufacturers have made the following small suggestions for improving the pollution problem of automatic spraying production lines.

1. Use coatings that do not contain organic solvents or have low organic solvent content as much as possible, which is the most effective method to solve the pollution of organic solvents, and reduce the amount of organic solvents, reduce the amount of organic solvent waste gas treatment, and concentrate the waste gas containing high concentration organic solvent Dispose, dilute and release to the atmosphere.

2. For the low-concentration and large-volume exhaust gas discharged from the spray booth, most of the previous treatment methods used paint mist flocculant or surfactant, but it is now recommended to use activated carbon adsorption method or activated carbon fiber bee wheel method to treat organic Exhaust gas.

3. For high-concentration and small-volume organic solvent waste gas discharged from the drying and curing furnace in the automatic spraying production line, the adsorption method, combustion method, and catalytic combustion method can usually be used for treatment.

The current automatic automatic spraying production line generally needs to meet the requirements of constant humidity, constant temperature and clean air, but some relatively recommended automatic spraying production lines are difficult to achieve the above points, which makes it difficult to reach the workpiece after spraying. Satisfactory painting effect. In order to avoid problems such as orange peel or pinholes in the coating, when spraying, we must control the temperature of the spray booth below 35 degrees Celsius and the humidity below 80%.
