Surface treatment method of curtain wall aluminum plate

Another method of surface treatment of curtain wall aluminum palte is electrostatic spraying. Spraying is divided into powder spraying and liquid spraying.

Powder spraying materials are mainly: polyurethane, swelling resin, epoxy resin and other raw materials are matched with high color retention pigments, and dozens of different colors of spraying powder can be obtained.

The sprayed powder is resistant to collision and abrasion. Under the impact of 50 kg, the aluminum plate is deformed, and the sprayed layer has no cracks, no layer drop, and integrity. It is resistant to dilute acid and mortar. The shortcomings are afraid of long-term exposure to ultraviolet rays, and the color of the yin and yang will be different after a few years.

The spray powder produced by many domestic manufacturers has great weight differences. After hanging on the wall, some powders containing gold chips will change with the angle of the sun. There will be changes during the day and dusk, and the color of the wall will be different. The use of powder spray paint hopes to attract attention.

Liquid spray coatings, fluorocarbon polymer spray coatings, commonly known as fluorocarbon spray coatings, are fluorocarbon polymer resins used to make paint and used as metal finishes. The combination with fluorine is currently a stable molecular bond.

Aluminum panels are easier to bend and process and form complex shapes, and can better adapt to the ever-changing needs of building exterior wall decoration. It is generally considered that single-layer aluminum panels are used as aluminum panel curtain wall materials. A variety of colors of sprayed surfaces are available, with good strength, low cost, and long life. If the aluminum plate is hung on the wall without direct contact with steel, it will not fall off and corrode for 50 years.

The life span may be longer to match the life span of the building. The single-layer aluminum curtain wall is made of pure aluminum 3mm or LF21 2.5mm aluminum single plate. The single-layer aluminum plate is developed due to the development of electric bolt welding technology. The electric bolt welding realizes the reinforcement welding on the back of the single-layer aluminum plate finish. Reinforcing ribs do not damage the aluminum veneer. The single-layer aluminum sheet is easy to bend and processed into complex shapes, with high strength and long life of up to 50 years. Therefore, its appearance makes the aluminum curtain wall rich in processing and installation forms.
