What is Powder Coated Aluminum Sheet
Powder-coated aluminum plate is a new process in the surface coating technology of aluminum plate, which is a coating process of coating in powder form and forming a coating film.
The spraying effect of powder spraying is superior to the spraying process in terms of mechanical strength, adhesion, муқовимат ба зангзании, and aging resistance. Compared with the spraying with the same effect, the cost is lower, and it can replace the traditional painting process in many occasions.
Дар айни ҳол, powder-coated aluminum sheets have been widely used, and can be used for exterior and interior wall decoration of buildings, indoor ceilings and so on.

Equivalent name for powder coated aluminum sheet
Powder coated aluminum sheet, also called electrostatic powder coating color sheet, is an upgraded product of traditional paint color-coated sheet. Its appearance promotes the traditional Powder coated aluminum sheet industry in my country. Entering the 2.0 era, it is called "a new generation of color-coated sheets".
The high-performance Powder coated aluminum sheet adopts the high-speed electrostatic powder coating equipment imported from France, and uses the principle of electrostatic positive and negative electricity attracting each other.It is a high-end new type of sheet formed by spraying 100% solid high-performance powder coating on the surface of the substrate and curing at a high temperature of 330 °C.
Powder coated aluminum sheet, низ маълум аст color-coated aluminum sheet, color-coated aluminum coil, aluminum-magnesium-manganese powder coated aluminum sheet, ва гайра., is widely used in large venues, фурудгоҳҳо, and high-speed railway stations because of its good durability, вазни сабук, and high lightness. theaters and other industries for public buildings and power plants, steel mills, chemicals, aquaculture and other industries that require high anti-corrosion performance.
Structure of Powder coated aluminum sheet
The choice of coating for powder coated aluminum sheets can be considered according to the needs of its application field and project cost. According to the weather resistance and corrosion resistance of the coating, the coatings are PVDF fluorocarbon (polyvinylidene fluoride), HDP high weather resistance polyester, PE polyester and other coatings.

6 advantages of powder coated aluminum sheet
- Good durability, aluminum plate comes with anti-corrosion function
Aluminum molecules combine with oxygen in the air to form an aluminum oxide film, which covers the surface of the aluminum plate, which can prevent further oxidation of the aluminum plate and form a natural protective film with its own anti-corrosion function.
- Вазни сабук, reduces load on support structures
The density of aluminum alloy is 2.73, which is one-third of the steel plate. It is light in weight and greatly reduces the load of the supporting structure. It is widely used in large-span construction fields such as airports, stations, and stadiums.
- High strength and rigidity
Due to the addition of metal components such as magnesium and manganese to the alloy aluminum plate, the strength and rigidity of the aluminum plate are greatly enhanced through the configuration of the components, and its load-bearing performance is improved.
- Good plasticity and easy processing
It can be bent into straight plate, inner arc, outer arc, fan shape, and can adapt to various roof shapes - курашакл, arc, fan shape, ва гайра., to meet the designer's design concept to the greatest extent;
- Coating types and colors can be selected as required
The surface of the aluminum plate can be painted with different colors and types of coatings according to the architectural style and design requirements, which solves the problems of cost and design time, and can fully display the artistic effect of the building.
- Recyclable and high value
After the ordinary color steel plate is corroded, it can only be sold for a few cents per kilogram. When the color-coated aluminum plate is recycled, the price can reach 8.5-9.5% of the aluminum plate, and the recycling value is significantly higher than that of the ordinary color steel plate.
What is the spraying process of Powder coated aluminum?
Аввал, the powder coating is sprayed on the surface of the aluminum plate with powder spraying equipment (electrostatic spraying machine). 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 then baked at high temperature Leveling cures into a final coating with various effects (different kinds of effects for powder coatings).

Compared with traditional painting process, the advantages of powder coating are:
1. High efficiency: due to the one-time film formation, the productivity can be increased by 30-40%
2. Energy saving: reduce energy consumption by about 30%
3. Less pollution: no organic solvent volatilization (excluding harmful gases such as toluene and xylene in paint coatings).
4. High paint utilization rate: то 95%, and the powder can be reused many times after recycling.
5. Good coating performance: one-time film forming thickness can reach 50-80μm, and its comprehensive indicators such as adhesion and corrosion resistance are better than those of paint technology.
6. High yield rate: before it is cured, it can be re-sprayed twice. There are many types of powder coating processes, and the common ones are electrostatic powder spraying and dipping.
Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, ифлос нест, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film.
Application of powder coated aluminum sheet
Because of its good durability, вазни сабук, and high lightness, powder coated aluminum sheets are suitable for large venues, фурудгоҳҳо, high-speed railway stations and other public buildings, as well as power plants, steel mills, chemicals, aquaculture and other industries that require high anti-corrosion performance.

The difference between fluorocarbon sprayed aluminum plate and powder sprayed aluminum plate
1. Fluorocarbon spraying is a kind of electrostatic spraying and also a method of liquid spraying, which is called fluorocarbon spraying. It belongs to high-grade spraying, and the price is higher.
The coating is used for PVDF fluorocarbon coating and PVDF special coating, which can be sprayed by powder spraying.
2. Powder coating is to spray powder coating on the surface of the workpiece with powder spraying equipment. Under the action of static electricity, the powder will be uniformly adsorbed on the surface of the workpiece to form a powder coating.
Powder coating thickness: 60-120 μm.
