aluminium panel painting process
1. Light weight, good rigidity and high strength. The weight of thickness 3.0mm aluminum plate is 8kg per square and has a tensile strength of 100-280n/mm2.
2.Good durability and corrosion resistance. PVDF fluorocarbon paint based on kynar-500 and hylur500 can be used for 25 years without fading. good corrosion resistance, color and gloss retention , make it long life and lasting as new.
3. Good craftsmanship. By adopting the process first and then spraying,the aluminum plate can be processed into a variety of complex geometric shapes such as plane, arc and spherical surface.
4. Uniform coating and diverse colors. The advanced electrostatic spraying technology makes the adhesion uniform between the paint and the aluminum plate, the coating surface is smooth and smooth, and the color is uniform and bright; while ensuring the continuity and consistency of color, the diversity of color makes it a large choice.
5. Rich types of coatings. Polyester, polyurethane, fluorocarbon, laminating and other coatings are available to meet special needs.
6.Not easy to stain, easy to clean and maintain.
The non-adhesiveness of the fluorine coating film makes surface difficult for contaminants to adhere, and has good cleanliness. Mingzhu’s self-cleaning aluminum sheets solve the problem of high difficulty cleaning for outdoor curtain walls aluminum panels.
7. Convenient and quick installation and construction. The aluminum plate is formed in the factory and does not need to be cut at the construction site, just fixed on the frame.
8. It can be recycled and reused, which is good for environmental protection. Aluminum plates can be recycled 100%, which is different from decorative materials such as glass, stone, ceramics, and aluminum-plastic panels, with a high recycling rate.
Application of color coated aluminium solid panel
Aluminum Veneer Case
Aluminum panels for curtain wall is a new type of curtain wall material,which uses high-quality aluminum alloy sheets as the base material,then be formed by CNC bending and other technologies, and the surface is sprayed with decorative coatings.Nowadays, most buildings use this kind of material for exterior wall or interior decoration. The sheet has a long durability and a very high recycling rate. It can be called an environmentally friendly green building material, and it is very suitable for various buildings.

Advantages of color coated aluminium solid panel
Color coated aluminium solid panel It has the advantages of both aluminum plate and organic material. It not only has the advantages of high mechanical strength, good toughness, and easy processing and forming of aluminum plate, but also has good coloring, decorative, and decorative properties of organic polymer coating materials.
Corrosion resistance, it can be easily processed by punching, bending, deep drawing, welding, etc. The products made by aluminium are practical, decorative, easy to process and durable. The adhesion between the printed layer and the bottom layer is high.
Our factory chooses high-quality fluorocarbon coatings from the world-renowned fluorocarbon coating manufacturers PPG, AKZO Akzo and other companies. The color selection is wide. Customers can directly select or provide color samples according to the color plates provided by the manufacturers.
Color coated aluminium solid panel Hydrochloric acid resistance test standard:
Use distilled water to prepare a 10% (volume ratio) hydrochloric acid solution (prepared with 37% industrial grade hydrochloric acid), and drop 10 drops on the paint film and cover it with an observation glass, with the convex surface facing up, take off the glass after 15 minutes, rinse with tap water, and check after drying.
