Structural steel Coating Machine

Structural steel Coating Machine

Electrostatic powder spraying is the principle of adsorption of positive and negative static charges to each other when the powder spraying equipment is working. The surface is then heat treated to create a dense surface coating on the surface of the workpiece.

1 Process Flow

1.Loading   the workpieces → 2. Pre-degrease → 3.Degrease → 4. Pickling   → 5. Washing → 6.Moisture Drying → 7.Natural cooling   → 8.Powder coating spray   →9.Curing(Normal 180ºC 20min) → 10. Natural cooling   → 11.Unloading

2 Mainly includes

1) Pretreatment: Dipping pretreatment with overhead crane, or fully automatic spraying pretreatment

2) Conveying system: light closed-circuit conveyor, power and free conveyor, overhead open conveyor, and so on

3) Oven: batch oven, hot air circulating drying oven, tunnel oven, bridge drying oven

4)Spray paint room type :Water spray paint room; Water spray paint room; Dry spray paint room; Ω spray paint room

5)Control system: PLC control, with or without touch screen

Advantage

The speed of the coating construction is fast,Continuous mechanization and automation operation can realize,reduce labor intensity ,uniform paint film, strong adhesion ,uniform coating level off,smooth,non-toxic,easy to operate,rust corrosion.
