Rustproof aluminum sheets

Last Updated: 2022-12-24

In terms of alloy composition, there are usually several kinds of rustproof aluminum sheets:

High purity rustproof aluminum sheet (made by rolling high specular aluminum sheet with 99.9 content)

Pure rustproof aluminum sheet (the composition is basically rolled from mirror aluminum sheet)

Alloy rustproof aluminum sheet (composed of aluminum and auxiliary alloys, usually aluminum-copper, aluminum-manganese, aluminum-base, aluminum-magnesium, etc.materialRust-proof aluminum sheet (rust-proof aluminum mirror aluminum sheet coated with thin rust-proof aluminum sheet for special purposes)

Rust-proof aluminum sheet is made of mirror aluminum sheet or aluminum alloy material through pressure processing to obtain a rectangular cross section, uniform thickness of rectangular material. The rustproof aluminum sheet used in buildings includes single-layer rustproof aluminum sheet, composite rustproof aluminum sheet and other materials. In recent years, single-layer rustproof aluminum sheet is more commonly used in rustproof aluminum sheet.

Rust-proof aluminum sheet is also a form, simply said to be made of rust-proof aluminum sheet instead of glass, rust-proof aluminum sheet is more used for wall protection and daylighting walls. Foreign rust – proof aluminum sheet has been selected single-layer rust – proof aluminum sheet. Single layer rustproof aluminum sheet is generally pure rustproof aluminum sheet. The thickness of rustproof aluminum sheet is 3mm, and the rustproof aluminum sheet is strengthened to strengthen the rustproof aluminum sheet surface strength. On the back of rustproof aluminum sheet, reinforcement reinforcement must be installed. Reinforcement reinforcement is made of thick aluminum belt. The rustproof aluminum sheet back why to install reinforcement, is in the case of positive and negative external pressure, rustproof aluminum sheet will not sag, two will not bulge, so as to avoid the rustproof aluminum sheet 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 sheet 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 sheet 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 sheet deformation, aluminum coating without cracks, no lost layer intact, dilute acid and mortar.
