Easy construction
Positive aluminum oxide plate has strong decoration, moderate hardness, can be easily bent into shape, continuous high speed stamping, convenient for direct processing into products, no need for complex surface treatment, greatly reducing the production cycle and production costs.
Good cold
Standard thickness of oxide film (3 m) aluminum alloy frame profile indoor long-term use no color, no corrosion, no oxidation, no rust.Thick oxide film (10 m) aluminum frame profile can be used outdoors, can be exposed to sunlight for a long time without discoloration.
Strong sense of metal
The anodized aluminum plate has high surface hardness, gem grade, good scratch resistance, no paint covering on the surface, keep the metal color of the aluminum plate, highlight the modern metal sense, improve the product grade and added value.
Fire retardancy high
Pure metal products, no paint and any chemical substances on the surface, no burning at 600 degrees high temperature, no toxic gas, meet the requirements of fire protection and environmental protection.
The fouling resistance is strong
No fingerprints, no stain marks, easy to clean, no corrosion spots.
Wide range of use
Suitable for all kinds of indoor and outdoor metal curtain wallboard, suspended ceiling, administrative office building, commercial building, airport, subway, light rail, exhibition hall, underground passage, hospital and other places.
Structure and properties of oxide film for aluminum alloy photo frame profile:
The anodic oxide film consists of two layers, a porous, thick outer layer growing above a dense, dielectric inner layer called a barrier (also known as an active layer).When observed by electron microscopy, almost all of the horizontal and vertical surfaces of the film appear tubular holes perpendicular to the metal surface, which penetrate the outer layer of the film to the barrier layer between the oxide film and the metal interface.The barrier layer is composed of anhydrous aluminum oxide, thin and dense, with high hardness and blocking the flow of electricity.The thickness of the barrier layer was 0.03-0.05 m, 0.5%-2.0% of the total membrane.
With each pore as the principal axis, the dense alumina around constitutes a honeycomb hexagonal body, called the cell, the entire membrane is composed of countless such cells.When the electrolyte is sulfuric acid, the sulfate content in the membrane is 13%-17% under normal conditions.The porous outer layer of the oxide film is mainly composed of amorphous alumina and a small amount of hydrated alumina, in addition to the electrolyte of the cation.Most of the excellent properties of the oxide film are determined by the thickness and porosity of the porous outer layer, which are closely related to the anodic oxidation conditions.
