Powder-coated aluminum profile features

Better corrosion resistance, excellent mechanical performance, impact resistance and flexibility.

It will not fade under ultraviolet radiation, keeping the original color and glossness.

It is an eco-friendly decorating material without containing any solvent.

Working principle of Electrostatic powder coating

Electrostatic powder coating is based on the principle of high voltage electrostatic electric field.

The metal guide ring on the spray gun head is connected to the high voltage negative electrode, and the coated workpiece is grounded to the positive pole.

A strong electrostatic field is formed between the spray gun and the workpiece.

When the carrier (compressed air) transports the powder from the powder feeding unit to the gas guiding ring of the spray gun through the conveying pipe, since the guiding ring is connected to the high-voltage negative electrode to generate a corona discharge, a dense electric charge is generated around the powder to bring the powder with the negative charge, under the combined action of electrostatic force and compressed air, the powder flies from the gun to the workpiece and is uniformly adsorbed on the surface of the workpiece.

After heating, the powder dissolves and remains flat to form a uniform, continuous and smooth coating.

Why powder coating

Powder coating is a type of coating that is applied as a free-flowing, dry powder.

1. Powder coatings emit zero or near zero volatile organic compounds (VOC).

2. Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.

3. Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating.

4. Powder coating production lines produce less hazardous waste than conventional liquid coatings.

5. Capital equipment and operating costs for a powder line are generally less than for conventional liquid lines.

6. Powder-coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid-coated items.

7. A wide range of specialty effects is easily accomplished which would be impossible to achieve with other coating processes.
