Powder spraying: electrostatic spraying of powder coatings, also known as spraying. It uses a special electrostatic spray gun. After the paint is sent into the spray gun with compressed air, it is negatively charged near the corona discharge electrode of the electrostatic spray gun, thus generating electrostatic force and dipole force. Then, under the pressure of the conveying gas, The paint particles fly away from the spray gun and fly along the power line to the positively charged workpiece, and are arranged according to the distribution density of the power line on the surface of the workpiece, so that the paint is firmly applied to the surface of the workpiece.
Paint copying: That is, a special electrostatic spray gun is used, and the air flow from the compressed air is used to form a pressure difference with the tube connected to the paint tank, so that the paint liquid is sucked up from the paint tank, and the compressed air flow is brought to the nozzle to blow fine Spray evenly on the surface of the workpiece.
The specific difference between the two: baking paint spraying curing temperature: 160 degrees 180 degrees after the curing film thickness: 3- ~ 60μm 60 ~ 90
Curing time: 20 ~ 30min 20 ~ 30min
Paint film hardness (pencil): 3H 2H
Impact resistance: 50KG / cm ^ 2
Corrosion resistance: 240h 500h
Optional effect: Flat light with dots and flat orange grain sand pattern Reference price: 23 / m ^ 2 28 / m ^ 2
