Solutions to Three Problems Encountered during Powder Spraying

We usually choose spray painting for furniture doors and windows, but in fact, compared to paint, plastic powder is our better choice. Spray painting is affordable, color corrected, and suitable for more households or factories to use. If the environment is less corrosive when spraying plastic powder, its sealing is enough to keep it for a long time. However, during the process of plastic powder spraying, some problems are inevitable. Let's listen to the solutions provided by professional manufacturers.

When the powder fluidization is not good

Insufficient air pressure: It is necessary to clean the air filter and increase the pressure appropriately.

Powder clumping: The powder needs to be manually loosened and filtered.

When powder blocks the gun

Poor powder fluidization: The powder loading in the fluidized bed should be reduced, and the powder addition should be controlled at 2/3 of the fluidized bed volume.

The content of ultrafine powder in the powder is relatively high: it is necessary to reduce the proportion of recycled powder added to the original powder and check the particle size distribution of the original powder.

3. When powder is sprayed onto the workpiece, powder clusters are generated

Compressed air contains moisture or oil: it is necessary to check the purification of the air source and improve the purification equipment for compressed air.

High content of ultra-fine powder in powder: It is necessary to reduce the proportion of recycled powder added to the original powder and check the particle size distribution of the original powder.

Excessive powder output: It is necessary to reduce the powder conveying pressure appropriately and control the powder supply to 150-200g/min.

When we only have paint as the only material for filling doors and windows in our minds, it means we are really out of touch. As a relatively new technology, plastic powder has entered the modern furniture processing industry. If you want to learn more about plastic powder materials, you can follow Zhejiang Xingshun New Material Technology Co., Ltd., a company specializing in the production of plastic powder.
