In terms of alloy composition, there are usually several kinds of rustproof aluminum plates:
High purity rustproof aluminum plate (made by rolling high specular aluminum plate with 99.9 + content)
Pure rustproof aluminum plate (the composition is basically rolled from mirror aluminum plate)
Alloy rustproof aluminum plate (composed of aluminum and auxiliary alloys, usually aluminum-copper, aluminum-manganese, aluminum-base, aluminum-magnesium, etc.materialRust-proof aluminum plate (rust-proof aluminum mirror aluminum plate coated with thin rust-proof aluminum plate for special purposes)
Rust-proof aluminum plate is made of mirror aluminum plate or aluminum alloy material through pressure processing to obtain a rectangular cross section, uniform thickness of rectangular material. The rustproof aluminum plate used in buildings includes single-layer rustproof aluminum plate, composite rustproof aluminum plate and other materials. In recent years, single-layer rustproof aluminum plate is more commonly used in rustproof aluminum plate.
Rust-proof aluminum plate is also a form, simply said to be made of rust-proof aluminum plate instead of glass, rust-proof aluminum plate is more used for wall protection and daylighting walls. Foreign rust – proof aluminum plate has been selected single-layer rust – proof aluminum plate. Single layer rustproof aluminum plate is generally pure rustproof aluminum plate. The thickness of rustproof aluminum plate is 3mm, and the rustproof aluminum plate is strengthened to strengthen the rustproof aluminum plate surface strength. On the back of rustproof aluminum plate, reinforcement reinforcement must be installed. Reinforcement reinforcement is made of thick aluminum belt. The rustproof aluminum plate back why to install reinforcement, is in the case of positive and negative external pressure, rustproof aluminum plate will not sag, two will not bulge, so as to avoid the rustproof aluminum plate repeated inside and outside vibration and vibration sound. If need sound insulation heat preservation, can be in the inside of rustproof aluminum board, put rock wool, mineral wool or foaming treatment.
Antirust aluminum plate surface treatment, can be divided into two methods, one is anodic oxidation, anodic oxidation of the oxide film in 12u or more, the color is only bronze and white two, the color is monotonous, so antirust aluminum plate surface treatment, can never be used for anodic oxidation. Another method is electrostatic spraying, spraying is divided into powder spraying and liquid spraying
Powder spray materials are mainly: polyurethane, polystyrene resin, epoxy resin and other raw materials with high color retention pigment, can get dozens of different colors of spray powder. The spray powder, collision resistance and friction resistance, under the impact of 50 kg, rustproof aluminum plate deformation, aluminum coating without cracks, no lost layer intact, dilute acid and mortar.
