01. SUMMARY OF MATERIALS

anodic oxidationAluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, under specific conditions and the action of the applied current, electrolysis.

Make a layer on the surface of aluminum plateDense oxide filmThe colorless porous nature of the anodic oxide film is used to achieve the purpose of dyeing and protecting the aluminum substrate.

02. Anodic oxidation process

The anodizing process is mainly from degreasing-etching-neutralization-anodizing-coloring-sealing.

03. Performance characteristics

a. Good processability

Anodized aluminum decorative strong, moderate hardness, can be easily bent forming, continuous high-speed stamping, convenient direct processing into products, no need for complex surface treatment, greatly reduce the production cycle and reduce production costs.

B. good weather resistance

Standard thickness oxide film anodized aluminum plate indoor use for a long time does not change color, no corrosion, no oxidation, no rust. The anodized aluminum plate with thick oxide film can be used outdoors and can be exposed to sunlight for a long time without discoloration.

c. Strong sense of metal

The anodized aluminum plate has high surface hardness, up to gem grade, good scratch resistance, no paint coverage on the surface, retains the metal color of the aluminum plate, highlights the modern metal sense, and improves the product grade and added value.

d. High fire resistance

Pure metal products, the surface without paint and any chemical substances, 600 degrees high temperature does not burn, does not produce toxic gases, in line with consumer environmental protection requirements.

e. Strong stain resistance

Leave no fingerprints, stain marks easy to clean, do not produce corrosion spots.
