What are the advantages of aluminum alloy shell? At present, the use of aluminum alloy shell has been very extensive, such as widely used in aviation, aerospace, high-speed trains, lithium-ion battery shell, machinery manufacturing, shipping and chemical industry, using aluminum alloy instead of steel materials, the structure weight can be reduced by more than 50%, so today we summarize the advantages of aluminum alloy shell as follows:
Advantages of aluminum alloy shell
What are the technical characteristics and technological process of surface treatment of aluminum alloy shell? Aluminum profile is a kind of aluminum material with different cross-section by hot melting and extrusion. In order to improve the decoration effect, enhance the corrosion resistance and prolong the service life, aluminum profiles generally need to be surface treated. Due to different principles, the process is also quite different. Next, let's share:
Anodized aluminum profile
Anodizing principle:
Aluminum and aluminum alloy anodizing is the process that aluminum or aluminum alloy products are placed in the electrolyte solution to form aluminum oxide film on the surface by electrolysis. The common method is direct current sulfuric acid anodizing.
Process: surface pretreatment - Anodizing - boiling water sealing
Principle of electrolytic coloring:
The method that metal ions in electrolytic solution infiltrate into the bottom of membrane pores to reduce deposition and make the film colored is called electrolytic coloring method, also called secondary electrolysis method.
Process: surface pretreatment, direct current sulfuric acid anodizing, electrolytic coloring, boiling water sealing or electrophoretic coating.
Anodized aluminum profiles can effectively protect materials from erosion, anti-static, non dust and easy to clean; fireproof, with excellent heat dissipation; light weight, only one-third of the proportion of stainless steel. The appearance is characterized by super metal texture, high-grade, beautiful and shining; uniform color, no fading; no fingerprint left after touching; anodizing process surface will never fall off, especially suitable for home use.
Electrophoretic coating of aluminum profile
Principle of electrolytic coloring:
With anodized (colored) products as anode, aluminum or stainless steel as cathode, and placed in heat curing acrylic transparent resin solution, under the action of external electric field, the paint particles with negative charge move towards the products, thus forming a paint film with adhesive on its surface.
Process: surface pretreatment - Anodizing - electrolytic coloring - Electrophoretic Painting
After anodizing and electrolytic coloring, the electrophoretic coating can protect the aluminum profile in two layers. With high transparency, high metal texture, high corrosion resistance and high weather resistance, it is more decorative than spray painting and powder spraying, and is deeply loved by users. It occupies an important position in the aluminum surface treatment process. At present, it has been widely used in home decoration, with a huge potential market.
