How to Coating Aluminum Coil?

What is Color-coated aluminum coil?

Color-coated aluminum coils are products obtained by coloring the surface of aluminum coils. Due to its high cost performance, it is widely used in aluminum ceiling, roof surface, scrap steel, canning, aluminum veneer curtain wall and other industries. So besides the cost-effective feature, does this product have other advantages?

1. Why use a coating aluminum coil?

Bright colors and strong decoration

The color-coated aluminum coils have a real sense of physical layering, giving people a fresh and elegant feel. In addition, different colors are not static and can be customized according to the specific development needs of enterprise customers. The performance quality of the finishing materials is very good.

The excellent technical performance and high folding resistance

The raw materials used in the production of this product are all high-quality materials, so there is no problem with the product quality. It is well applied under different working pressures, different ambient temperatures and humidity, and is not prone to bending deformation and shell expansion, and the application effect is good.

2. Coating method of aluminum coil

Aluminum coil coating is mainly anti-corrosion. We will now focus on how aluminum coil coatings are made.

Brush coating of aluminum coil

The brushing method is an early, simple, and traditional manual coating method. It is easy to operate and flexible, and can be applied to objects of any shape. In addition to dry and poor leveling coatings, it can be applied to various coatings. The brushing method can make the paint penetrate the pores of the metal surface and enhance the adhesion between the paint film and the metal. Its disadvantages are high labor intensity, low work efficiency and poor coating appearance.

Scratch Coating of aluminum coil

Blade coating is a method that cannot be used to coat a car with a blade. Used for coating liquid coatings with high user viscosity and high solids content. During the blade coating operation, the common safety problems of the coating film are cracking, falling off, rolling, etc., and the thickness of the coating film is difficult to achieve uniformity.

Dip coating of aluminum coil

Painting is also a traditional Chinese painting technique. In this method, the object to be coated can be dipped into a tank liquid containing paint, then removed, and excess paint dripped back into the tank liquid, or excess paint can be drained by various mechanical design methods. This method has a high risk of solvent loss, is easy to develop, and contributes to ambient air quality pollution. It is not suitable for volatile paints, and the thickness of the coating film is not easy to be uniform. Generally speaking, it is mainly used for equipment or artifacts with complex social structures.

For example: In chemical plants, some equipment, such as combined heat exchangers, can be constructed by full-dip coating, because the inner tube cannot be sprayed. Aluminum dipped steel pipes are mainly used in petrochemical furnace tubes, various heat exchanger tubes, fractionation tower tubes, etc.

Spray coating of aluminum coil

Flow coating is a coating process in which the paint is sprayed from the nozzle to the surface of the object to be coated, and the paint flows from top to bottom to completely cover the surface of the object to be coated to form a coating film. The equipment adopted in the method is simple, it is relatively easy to realize mechanized production, the operation is simple, and the production efficiency is high, but the coating film is not smooth or the coverage is incomplete. The thickness of the coating film is not easy to be uniform. Flow coating consumes more solvent than dip coating and can also cause contamination problems.

Spray of aluminum coil

Spraying is to use the negative pressure generated by data compressed air at the nozzle of the Spraying is to use the negative pressure generated by the data compressed air at the nozzle nozzle to bring the paint into the container. The paint in the container is sprayed out through the nozzle, and immediately enters the high-speed compressed air flow in China, so that the paint liquid develops and spreads rapidly. The mist particles are fired at the object and evenly coat the surface. This method requires that the paint to be sprayed has a relatively low viscosity. Often added to paint as a thinner. It is suitable for various architectural coatings and various objects in enterprises, and it is a relatively systematic and extensive coating process.
