As a new generation of home consumers, when you choose doors and windows,
What aspect of the product do you look at at first?
Living in an era of looking at faces, only by first being attracted by the appearance, we will understand the connotation and soul of a product, the so-called appearance is justice, then, aluminum alloy door and window profile surface treatment process, how much do you know?
Aluminum profile is an important part of door and window products, and its surface treatment is the key to improving aesthetics and practicality.
Different profile surface treatment processes make the doors and windows adapt to different environmental conditions and weather resistance; Our common surface treatment processes for aluminum alloy profiles are mainly as follows:
š Anodizing
š Electrophoresis
š Wood grain transfer
š Electrostatic powder spraying: ordinary powder, fluorocarbon powder, etc
šĀ Fluorocarbon paint spraying
PART01 Anodizing
Anodizing is a surface treatment process of aluminum profiles, which is a process in which the aluminum profiles are put into a specific water-soluble solution, and the pigments in the solution are adsorbed on the aluminum profiles through time immersion, so that a layer of oxide film is formed on the surface of the profile.
Steps:Ā WashĀ āĀ pickleā anodizeāĀ colorā seal the holes
Generally, we see the freshly extruded aluminum profile, the corrosion resistance of its surface is not strong, after the anodizing process, the surface of the aluminum profile will form aĀ dense, porous, strong adsorption film layer.
ā Advantages: increase the corrosion resistance, wear resistance and appearance aesthetics of aluminum profiles;
š„ Disadvantages: water-soluble solution is not easy to master, and the color is larger;
The surface protective film is relatively thin, easy to scratch, affecting the appearance;
The colors are generally black and gray, and the colors are relatively monotonous, so the choice of color will be limited.
āĀ Application scenarios:Ā aviation, construction, electronics, etc.;
PART02 Electrophoresis
Electrophoresis is a metal surface treatment process, this technology is similar to electroplating, it can coat various metal parts, mainly to play a role in anti-corrosion and surface decoration of the substrate, this process was first used in automotive primers, and later extended to the aluminum alloy door and window industry because of its good decorative effect.
The electrophoresis process refers to the aluminum profile and the corresponding electrode are connected to the water-soluble solution, andĀ the current is used to attract the suspended coating particles in the solution, so that our polyurethane coatings and pigments are evenly precipitated on the surface of the aluminum profile to form a water-insolubleĀ “paint film”.
Steps: Electrolysis (decomposition) ā electrophoresis (swimming, migration) ā electrodeposition (precipitation) ā electroosmosis (dehydration)
ā Advantages: The “protective film” formed by the electrophoresis process makes the surface of the aluminum profile smooth, and even achieves the effect of mirror, with a shiny appearance, excellent weather resistance, corrosion resistance, moisture resistance and other characteristics
š„ Disadvantages: The surface is prone to scratches, which affects the overall aesthetics of doors and windows;
āĀ Application scenarios:Ā biomedical field, food safety field, environmental monitoring field, etc.;
Aluminum alloy is too cold
The wood is warm but too expensive
In between, there’s a better solution
That is the wood grain transfer process technology
PART03 Wood grain transfer
Wood grain transfer printing is to put the film printed with wood grain pattern on the surface of the aluminum profile, and then transfer the wood grain group on the film to the surface of the aluminum profile under the condition of high temperature and high pressure to achieve a seamless connection, overall beauty, rich color and real effect.
ā Advantages: The surface of the aluminum profile with wood grain transfer technology has a strong three-dimensional sense and a slightly soft texture, which can better reflect the natural feeling of wood grain, and is an ideal energy-saving process to replace traditional wood.
ā Common colors: ash, cherry, technical wood, etc.
ā Style recommendation: Chinese style, pastoral style, Japanese style, retro Nordic style, etc.
āĀ Application scenarios: aluminum alloy doors and windows, anti-theft doors, fire doors, metal trims and other high-temperature resistant metal materials.
