Powder spraying equipment

Description

Powder spraying, is to use powder spraying equipment to spray powder coating to the surface of the workpiece. Under the action of static electricity, the powder will be uniformly adsorbed on the surface of the workpiece to form a powder coating; the powder coating is cured by high temperature baking and leveling. It becomes a coating with different effects; the effect of powder coating is superior to the painting process in terms of mechanical strength, adhesion, corrosion resistance and aging resistance. The powder electrostatic spraying of the workpiece by using the powder spraying device is to adsorb the charged powder particles to the surface of the workpiece under the action of an electrostatic field, and to form a coating by leveling and solidification.

The powder spraying equipment includes a powder spraying room, a powder supply system (including a gun + hoist), a recovery device, a ventilation system, etc., and the recovery device has a bag, a cyclone, a filter element, a small cyclone + a filter bag, a small cyclone + a porous plate, and the like.

Characteristics

1. Efficient: Since it is a one-time film formation, it can increase productivity by 30-40%.

2. Energy saving: reduce energy consumption by about 30%.

3. Less pollution: no organic solvent volatilization.

4. High utilization rate of paint: up to 95%, and can be used multiple times after powder recovery.

5. Good film properties: one-time film thickness can reach 50-80μm, its adhesion, corrosion resistance and other comprehensive indicators are better.

6. High yield: before uncured, can be double re-spray.

Powder electrostatic spraying can improve the working conditions of workers without using solvents, and will not cause solvent pollution to the atmosphere. Since the powder can be recycled, the utilization rate of the raw materials is improved, the consumption cost of the material is lowered, the coating film performance is superior, and the acid resistance, alkali resistance and salt corrosion resistance of the paint coating film are better.
