Industrial aluminum alloy profiles have a wide range of uses, with a variety of uses. In addition to their fast aluminum extrusion process and low cost, it also depends on the surface treatment of aluminum profiles to make a variety of colors, which can meet the various application scenarios of customers in various industries. The color of industrial aluminum alloy profiles is obtained by different surface treatment processes, Below, Yongyu Metal's editor will introduce to you the colors that can be achieved by different surface treatment processes for aluminum profiles, as well as the advantages of various surface treatment processes for aluminum profiles.
What are the surface treatment processes for industrial aluminum alloy profiles?
1. Ordinary powder spraying
2. Fluorocarbon spraying has certain differences from the powder spraying above
3. Electrophoresis
4. Anodization
5. Transfer wood grain
Anodizing, electrophoresis, and spraying are the main surface treatment processes for aluminum profiles. Anodizing is generally done by anodizing to form a dense oxide film on the surface of aluminum profiles, thereby solving the corrosion problem of aluminum profiles. The more popular method now is powder coating spraying, which sprays a layer of powder coating on the surface of aluminum profiles, which is not only aesthetically pleasing but also corrosion-resistant, and has a good decorative effect.
Our Colors
List several colors that can be used for surface treatment of industrial aluminum alloy profiles:
1. The colors that can be achieved by electroscopic treatment of aluminum profiles: This surface treatment method gives industrial aluminum profiles champagne, silver white, matte white, antique copper, gold, and black colors
2. The colors that can be done for surface treatment of aluminum profiles by spray coating: This treatment method is consistent with the surface color of electroscopic treated profiles, including champagne, silver white, matte white, antique bronze, gold, and black.
3. The colors that can be made for surface treatment of aluminum profiles by spraying: according to the actual needs of customers, they can be processed into any color.
Regarding the quality issue of anodized surface treatment of aluminum profiles:
1. There are spots on the surface.
This anomaly is usually caused by poor metal quenching and tempering or poor material itself. Treatment methods include re heat treatment. Or replace the material.
2. Rainbow color appears on the surface.
This anomaly is generally caused by anode operation errors, which loosen during hanging and cause poor conductivity of the product. Solution: Power off and re anodize.
3. Surface scratches and severe scratches
This kind of abnormality is usually caused by careless operation during transportation or processing. The solution is to turn off the power, polish and re power.
4. White spots appear on the surface during dyeing.
This anomaly is generally caused by the presence of oil or other impurities in the water during anode operation.
Standard for anodized surface treatment of aluminum profiles:
1) The film thickness is 5-25um, the hardness is above 200HV, and the color change rate in the sealing experiment is less than 5%;
2) The salt spray test lasts for more than 36 hours and can meet CNS standards of level 9 or above
3) The appearance should not have any scratches, scratches, colored clouds, or other phenomena. There should be no hanging points or yellowing on the surface
