Comparison of fire resistance, hardness and corrosion resistance between aluminum veneer and aluminum plastic sheet.

Aluminum plastic composite panels, referred to as aluminum plastic panels, were introduced into the domestic decorative material market in the early 1990s. And after the test of time, the shortcomings of aluminum-plastic panels are gradually found by decoration companies and owners, although there are still someA part of the market space, but at present, it is basically replaced by new materials such as aluminum veneer curtain wall. The main reason is that the fire resistance of aluminum veneer is better than that of aluminum plastic panel, including the rigidity and corrosion resistance of the panel surface. By comparison, the decorative products of aluminum panel curtain wall win out with absolute performance advantages.

When the aluminum-plastic composite board was just launched, the traditional porcelain plate wall decoration was eclipsed by its rich color and light weight. Although the production technology is still improving, because of the structural characteristics of the material itself, it is bound to be unable to meet the decoration needs of many places. First of all, the structure of the aluminum-plastic panel is generally divided into 2-3 layers, the middle layer is PE plastic, and the surface is compounded with a layer of super Thin aluminum plate, but because the aluminum panel is too thin, the hardness is still a big pain point, and the middle layer is plastic material after all. After 3-5 years of use, the corrosion resistance of the aluminum plate can not be compared with that of the pure aluminum plate. Because the wall decoration plate is mostly used in outdoor walls, billboards and other places, no matter how good the plastic can not withstand the wind and sun, the years of high and low temperature difference. In terms of fire performance, according to the provisions of GB / T 11748-2008, the fire protection level of aluminum-plastic sheet is required to be above grade B before it can be put on the market. The so-called grade B fire prevention refers to the materials with certain flame retardancy and no open fire. However, the thick smoke produced by the aluminum plastic plate is also an extremely unsafe poisonous gas when it comes to high temperature.

The key point is that the aluminum veneer curtain wall recommended in this paper can be said to be an upgraded version of the aluminum-plastic panel, which solves the shortcomings of various materials mentioned above, regardless of the structure and rigidity of the panel surface, natural climate corrosion resistance, and fire resistance. Moreover, it not only solves the above shortcomings. In terms of panel color and modeling structure, aluminum veneer is more extensive than aluminum-plastic panel. It is no longer a simple flat modeling, and any color you like can be modulated. Because of the excellent plasticity of aluminum sheet, the bending process of aluminum sheet will not directly fracture like that of aluminum-plastic plate, and aluminum plate building materials have high recycling value. In terms of fire performance, aluminum veneer is A2 based fireproof material, resistant to 600 ℃ high temperature, and does not smoke.

According to the CAD design drawings and effect drawings provided by the manufacturer, we can customize various artistic shapes according to the requirements, such as flat curtain wall, bending corner, hollow carving, lettering, arc, etc., which can be customized according to the wall modeling. In terms of baking paint color, we can also carry out fluorocarbon or powder paint color modulation according to the preferences of decoration companies and owners. Like the modern effect, can be seven color paint, color mix and match. Like retro effect, the board can be imitated wood grain stone grain, so that the board has a variety of wood or marble texture.

The various performance advantages of the above metal decorative building materials are also one of the reasons why the price of aluminum veneer is higher than that of aluminum plastic panel. With the attention and pursuit of beautiful personality of architectural decoration, safety, environmental protection and durability, many national infrastructure projects are mainly made of aluminum plate decoration materials. There are also many investors who have demand for the above problems and are not poor in money This kind of new material gives the building decoration company and the design company great play space.
