The truss of aluminum, aluminum, ultra-thin light box, eight prism exhibition equipment quality difference, the use of sunlight, air, water and influence, cause the deformation of aluminum, will even cause the glass breaks off phenomenon. Its characteristics are as follows:
1, aluminum truss, eight prism, chemical composition of aluminum containing ultra-thin light box does not meet the standard. SHS truss to add a lot of mixed aluminum, aluminum eight prism aluminum scrap, can greatly reduce the price of the truss, but may lead to unqualified eight prism, exhibition equipment construction aluminum profile of chemical composition, seriously endanger the safety of the engineering construction.
2, truss and eight prism film thickness does not meet the standard. Standard building frame exhibition equipment ultra-thin light box aluminum oxide film thickness should be not less than 10 microns. The thickness is not enough, the surface of the truss is easy to rust and corrosion. Some sample names, eight prism and truss products production license, certificate of aluminum, the thickness of the oxide film is only 2.4 microns, and some even have no oxide film. According to expert estimates, each reduced the thickness of the oxide film of 1 microns per ton of personal data can reduce the cost of power consumption 150 yuan.
3, inferior aluminium reduced a lot of closure time, reduces the loss of chemical reagents, truss price and eight prism panels cost is reduced, but the corrosion resistance of the materials in the exhibition equipment, greatly reduced.
4, try to reduce the wall thickness of truss section. 90 series of aluminum profiles, eight prism according to national standards for the ultra-thin light boxes, aluminum wall thickness minimum of not less than 1.4 mm, in some products in Guangdong only 0.6 to 0.7 mm. 46 series gantry bombing, hidden frame using the national exhibition equipment standard aluminum wall thickness minimum of not less than 1.62 mm, check, some products in Guangdong only 0.97 mm to 1.18 mm.
