Aluminum solid panel is mainly used in some larger buildings such as hotels, subways, conference halls, and exhibition halls. Compared with aluminum-plastic panels, aluminum veneer has its own unique advantages to a certain extent.
As far as the reinforcement material of the aluminum plate is concerned, the aluminum veneer has a certain thickness, and as a metal material, it is not flammable by itself, and can basically meet the requirements of high-rise buildings for fire protection capabilities. The surface aluminum sheet of the aluminum composite panel material is thin, and it is flammable in fire. When the sandwiched polyethylene material burns, it will emit some toxic gases.
Second, from the perspective of the moldability of the two materials. The aluminum solid panel can be welded and is suitable for various building forms to easily reflect design creativity. There is no limit to multi-dimensional modeling. The bottom bracket is supported by metal materials, which can effectively increase the strength of building materials. Aluminum-plastic panels can guarantee the treatment of two-dimensional deformation, but the requirements for shapes such as circular arcs cannot be met.
From the point of view of its bending performance, the aluminum veneer is sprayed on the surface of the aluminum veneer with a rotating high-pressure gun. It is usually carried out after the material processing is completed. There is no direction. The spray thickness at the corners must be consistent with the surface of the aluminum veneer. The thickness is consistent. The surface of the aluminum-plastic panel is decorated by roll coating with PVDF fluorocarbon polymer resin. Roll coating technology is generally carried out in the production and molding of aluminum-plastic panels, proceeding in a certain direction, and the coating at the corners opens, which greatly reduces the performance.
Aluminum veneer generally chooses 2-3mm thick aluminum alloy plate with anti-rust function as the base material, while the aluminum-plastic plate material is 0.5mm thick aluminum plate on both sides, and the middle layer is 3-5mm plastic plate.
As a major choice of architectural decoration materials, aluminum veneer, compared with aluminum-plastic panels, enjoys a broad space for development due to its unique advantages. We like to divide aluminum veneer into curtain wall products. The aluminum veneer undergoes alkaline degreasing, alkaline etching, pickling, chromium and pure water treatment, and then spraying process. Aluminum veneer and aluminum composite panel are two types of typical products in aluminum alloy curtain wall materials. When choosing them, they should be selected according to the individual's specific ability, the specific needs of the building, and the environmental impact.
