Application of dehumidifier in electrostatic powder coating industry

1. Shrinkage caused by surfactant residue due to unclean oil removal in pretreatment or unclean water washing after oil removal. The solution is to control the concentration and proportion of pre degreasing tank and degreasing tank liquid, reduce the amount of oil carried by the workpiece and strengthen the washing effect.

2. Shrinkage caused by excessive oil content in water. The solution is to add water filter to prevent oil leakage of water supply pump.

3. Shrinkage caused by excessive water content of compressed air. The solution is to discharge the condensed water of compressed air in time.

4 shrinkage caused by moisture in powder. The solution is to improve the storage and transportation conditions of powder and increase dehumidifier to ensure the timely use of recycled powder

5. The oil on the suspension chain is blown down to the workpiece by the air conditioner. The solution is to change the position and direction of air supply outlet.

6 shrinkage caused by powder mixing. The solution is to clean the powder spraying system when changing powder.
