The surface of aluminum alloy door and window profiles is sprayed with electrophoretic paint, powder-coated profiles, and fluorocarbon paint-sprayed profiles. As a new type of low-pollution, energy-saving, resource-saving, protective and anti-corrosive coating, electrophoretic coating has the characteristics of smooth coating film, good water resistance and chemical resistance, and can easily realize the mechanization and automation of the coating industry. , suitable for painting workpieces with complex shapes, edges, corners, and holes. It is widely used in the painting of hardware parts such as automobiles, automatic vehicles, mechanical and electrical appliances, and home appliances.

Electrophoretic coating can achieve complete mechanization and automation, which not only reduces labor intensity, but also greatly improves labor productivity, and is suitable for a large number of assembly line operations.

The electrophoretic coating has a high penetration rate and is completely dissolved or emulsified in water. The viscosity of the prepared bath liquid is very low and can easily penetrate into the bag-like structures and gaps of the object to be coated. It is especially suitable for special-shaped coatings. Surface coating of conductive materials.

Maintenance and maintenance of aluminum alloy doors and windows:

1. When using aluminum alloy doors and windows, move gently and push and pull naturally; if you find any Don't push hard when it's difficult, troubleshoot first. Dust accumulation and deformation are the main reasons why it is difficult to replace the old and new aluminum alloy doors and windows. It is necessary to keep the door frame clean, especially the sliding groove. Use a vacuum cleaner to remove dust accumulated in the groove and on the door seal strips.

2. When cleaning aluminum alloy doors and windows, people should not step on the aluminum frame or pull on the frame for support.

3. For aluminum alloy doors and windows, you can use a soft cloth dipped in water or neutral detergent. Do not use ordinary soap and washing powder, let alone strong acid-base cleaning agents such as scouring powder and toilet detergent.

4. After a rainy day, the wet glass and door and window frames should be wiped dry in time, and special attention should be paid to drying the water in the chute. If the chute is used for a long time, the friction will increase. You can add a little engine oil or apply a layer of fire wax oil.

5. The connection parts of the aluminum alloy frame should be checked frequently, the bolts should be tightened in time, and damaged parts should be replaced. The vulnerable parts of aluminum alloy doors and windows such as positioning pins, wind braces, and floor springs must be inspected frequently and lubricated regularly to keep them clean and flexible.
