The processing of
architectural aluminum profiles can be divided into raw aluminum and cooked aluminum. Raw aluminum is less than 98% aluminum, which is brittle and hard in nature and can only be foundry products. And ripe aluminum is more than 98% aluminum, its nature is soft, can be rolled or rolled many kinds of utensils. So what are the characteristics of poor architectural aluminum profiles:
1. Unqualified chemical composition. The cost of architectural aluminum profiles doped with a large amount of miscellaneous aluminum and waste aluminum will be greatly reduced, but it will lead to unqualified chemical composition of architectural aluminum profiles. Serious will also endanger the safety of the construction project.
2. The processing of inferior architectural aluminum profiles will greatly reduce the sealing time, reduce the loss of chemical reagents, and reduce the cost, but the corrosion resistance of architectural aluminum profiles is also greatly reduced.
3. Thin thickness of oxide film. If the thickness is not enough, the surface of architectural aluminum profiles is prone to rust and corrosion. According to experts' estimates, every 1um reduction in oxide film thickness can reduce the power consumption cost per ton of architectural aluminum profiles. Unqualified architectural aluminum profiles will cause deformation of architectural aluminum profiles, and even cause glass breakage and falling off when used because of the influence of air, rain and sunlight.
