People often ask why aluminum veneer spraying is divided into electrostatic and liquid powder. Why is it so confusing? There are several types of spraying, what are their effects, and the prices are different. What are these types of spraying? I don’t understand the effect of spraying, so today I will briefly analyze spraying.

Spraying is a process that is simply divided into electrostatic machine spraying and manual spraying. Powder and gas carbon are surface materials used on products. Fluorocarbon spraying is a kind of electrostatic spraying. Powder spraying uses powder spraying equipment to spray powder coatings onto workpieces. surface.

Fluorocarbon spraying is a kind of electrostatic spraying and a liquid spraying method. It is called gas carbon spraying and is called copper oil in Hong Kong. The coating used is PVDF fluorocarbon coating or PVDF special fluorocarbon primer, both of which are solvent-based liquid coatings. The suitable baking temperature for fluorocarbon PVDF coating is: 230℃, 15min.

Powder spraying uses powder spraying equipment (electrostatic spraying machine) to spray powder coating onto the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating. The coating used is powder coating, commonly known as plastic powder. The main types are: epoxy polyester powder coating (indoor powder), polyester powder coating (outdoor powder), epoxy powder coating (anti-corrosion powder), powder coating is solvent-free of solid coatings. Powder coating baking temperature: indoor plastic powder

180'℃, 20min; outdoor plastic powder: 200℃, 20min;

Fluorocarbon spray coating has excellent resistance to fading, blooming, corrosion resistance from atmospheric pollution (acid rain, etc.), strong UV resistance, strong crack resistance and the ability to withstand harsh weather environments. Fluorocarbon spraying: more than 15 years, up to 30 years without fading or discoloration; powder spraying (pure polyester powder): 7-8 years

Some fade in 3-5 years.

After high-temperature baking, leveling and solidification, powder spraying becomes a coating with different effects (different types of powder coating effects); the spraying effect of powder spraying is superior to the spraying process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc. , the cost is also lower than spray painting with the same effect. The price of fluorocarbon spraying is more than 40% higher than that of powder coating.
