Industrial aluminum profile is a kind of aluminum material that have different cleansing shapes through hot melt and extrusion. In order to improve the decorative effect, enhance the corrosion resistance and prolong the service life, industrial aluminum profile is generally only surface treated. Due to different principles, the process is also quite different.
Anodizing principle of aluminum profile in anodizing industry:
The process of forming alumina thin film on the surface of aluminum or aluminum alloy products is by electrolysis in the solution of indigo matrix.The common method is direct current acid anodic oxidation.
Electrophoretic coloring principle of aluminum profile for electrophoretic coating industry:
By the products after anodic oxidation (color) as anode, aluminum or stainless steel as the cathode, put in hot type of acrylic transparent numerical solution, under the action of electric field, coating of negatively charged particles move to the products, thus forming a layer on the surface coating with adhesiveness.
Process: surface pretreatment - anodizing - electrolytic coloring - electrophoretic coating
Electrophoretic coating
industrial aluminum profile in the industrial aluminum anodized and electrolytic coloring after electrophoretic coating, a double protection. With high transparency, metal texture, corrosion resistance and weather resistance, it is more decorative than spray paint and powder coating. It is deeply loved by users and occupies an important position in the implementation of surface treatment technology. Now it has been widely used in home decoration. The potential market is huge.
Process: Surface Pretreatment - Anodizing - Boiling Sealing
