Aluminum is divided into raw aluminum and cooked aluminum. Raw aluminum is less than 98% aluminum, which is relatively brittle and hard, and can only be found in sand casting products; cooked aluminum is more than 98% aluminum, soft in nature, and can be rolled or punched for various utensils. Hangzhou Hongcheng Precision Machinery Co., Ltd. is a professional manufacturer of aluminum foundry and aluminum die-casting, capable of producing high-quality products. Let's talk about the identification of inferior aluminum profiles.
1. Unqualified chemical composition
The cost of aluminum profiles doped with a large amount of miscellaneous aluminum and waste aluminum in the product will be greatly reduced, but it will lead to substandard chemical composition of architectural aluminum profiles, which will seriously endanger the safety of construction projects.
2. Reduced closing time
Inferior-quality aluminum profiles greatly reduce the sealing time, reduce the loss of chemical reagents, and reduce the cost, but the corrosion resistance of the profiles is also greatly reduced.
3. Thin oxide film thickness
The national standard stipulates that the oxide film thickness of architectural aluminum profiles should not be less than 10um (microns). If the thickness is not enough, the surface of the aluminum profile is easily rust and corrode. Some aluminum profiles without production name, factory address, production license, and certificate of conformity in the random inspection have an oxide film thickness of only 2 to 4um, and some even have no oxide film. According to expert estimates, every reduction in the thickness of the oxide film by 1um can reduce the cost of electricity consumption by more than 150 yuan per ton of profiles.
4. Unqualified chemical composition
Aluminum profiles mixed with a large amount of miscellaneous aluminum and waste aluminum can greatly reduce the cost, but it will lead to unqualified chemical composition of architectural aluminum profiles and seriously endanger the safety of construction projects.
Unqualified aluminum profiles will be deformed due to the influence of air, rain, etc. during use. Inferior aluminum profiles are not only tofu slag projects, but also endanger our safety. Therefore, we must find a reliable one. factory. Electronic Controller Accessories-Bottom Cover-300T
