What are the surface treatment methods of aluminum alloy doors and windows?

Overcoming the defects of aluminum alloy surface hardness, wear resistance, etc., anodized aluminum profiles, antistatic, easy to clean without dust collection, excellent heat dissipation, super strong metal texture in appearance, high-end and beautiful, uniform color, No fading, effectively improve the bonding force of organic coating and inorganic covering layer. Anodizing is currently the most widely used and most successful surface treatment technology for doors and windows.

Electrophoresis means that the electrophoretic coating is on the cathode and anode. Under the action of voltage, the charged coating ions move to the cathode.
And it interacts with the alkalinity generated on the surface of the cathode to form insoluble matter, which is deposited on the surface of the profile.

Under the action of static electricity, the powder is evenly adsorbed on the surface of the workpiece to form a powder coating, and the powder is evenly adsorbed on the surface of the workpiece to form a powder coating; superior to coating processes.
Advantages and disadvantages of electrostatic powder coating.

The basic process of fluorocarbon spraying
● Pretreatment process: aluminum degreasing and decontamination → washing → alkali washing (degreasing) → washing → pickling → washing → chromium washing → pure washing.
● Spraying process: Spray primer → topcoat → cover varnish → baking (180-250°C) → quality inspection.
Advantages and disadvantages of fluorocarbon spraying.

The main function is surface cleaning. Sandblasting of aluminum alloy doors and windows before painting (painting or plastic spraying) can increase the surface roughness, which has a certain contribution to the improvement of adhesion, but the contribution is limited. It avoids the defect that bright aluminum alloy profiles will cause light interference in certain environments and conditions in building decoration. Its surface is as delicate and soft as brocade, which is very popular in the market, but the existing frosted materials must be overcome. Surface grit is uneven and lack of patterning can be seen.

As the name suggests, wood grain transfer printing is a surface treatment technology that reproduces various wood grain textures on the surface of aluminum profiles. Because wood grain color satisfies consumers’ pursuit of a natural and comfortable life, it contains a huge potential market. Xingda doors and windows are found to have clear surface patterns, pure colors, and strong sense of hierarchy (currently popular are skin lines, BMW lines, etc.), and are enthusiastically sought after by many consumers. The wood grain transfer printing has excellent anti-aging and fading, corrosion resistance and weather resistance, fully displaying the beautiful wood grain texture, and adding a lot of color to the home environment.
