Powder Coating is a very important and most widely used surface treatment for racking & shelving industry.
Powder Coating is a technology which use solid powder as a surface treatment instead of liquid paint. Powder coating use high electrical pressure to bring negative current to powder, under the help of static electricity, make powder attach the surface firmly. Static electricity is a new tooling method, the powder used don’t have liquid, you don’t need to dilute it when use it. The powder is not fluid, it can be only fluid after melt. It won’t stick onto surface like liquid. Thus electricity powder coating have high paint efficiency. There won’t be solvent volatilize. The advantage is less environment contaminate. Which can help save energy and tool quickly. It’s also easy to work automatically.
We called the process of solid powder attach in the surface as powder coating. The working theory is use electricity make powder attach the surface. The process is: the powder was put into spray gun through pressure air, in the beginning of spray gun, there is high pressure static electricity maker, they release electricity to the powder. The powder affect by electricity then stick onto the product with opposite electricity. When the powder increased to a certain amount, the static electricity also accumulate to a certain amount which will repel the powder, all this process make the product have a required thickness of powder. Then under the help of high temperature, the powder melt and solidifying, which make a staff film in the product surface.
The advantage of powder coating is below:
1. It’s unti corrosion and suitable for different environment, which also increase the life of racking & shelving system.
2. The powder coating with different color looks very beautiful, also increase the mechanical strength of pallet racking & shelving
3. The powder is good for grinding and prevent product from extend temperature.
4. The surface will be smooth and looks beautiful
The general working process of metal surface treatment is:
1. acid wash to clean dust & rust and oil then phosphating.
2. Powder coating with good quality powder, T Racking use polyester powder
3. High temperature solidify
4. Cooling down
Powder coating is very important for the quality of various pallet racking & shelving system. As this have direct relation to the life time of product. T Racking always put powder coating as a important part of quality monitor, we offer 5 year warranty for all of our product.
