Application And Advantages Of Aluminum Profiles

Building doors and Windows on the market are mainly aluminum alloy doors and Windows and plastic steel doors and Windows and solid wood doors and Windows, aluminum wood composite doors and Windows. Among them, aluminum alloy doors and Windows account for more than 60% of the entire market, and the market is more widely used. Green consumption is becoming the dominant concept in the construction consumption market. Improving the energy saving and quality of doors and Windows is one of the important ways to improve building energy saving at present. Although the area of doors and Windows only accounts for about 1/5 of the outer protection area of the entire building, the energy consumption of doors and Windows accounts for 50% of the total energy consumption of the entire building. It is self-evident that the energy saving of doors and Windows is important to improve the energy saving of the whole building.
Electrostatic powder coating technology for building aluminum profiles is a surface treatment technology that has risen rapidly in recent years. It is characterized by no solvent, no pollution to the environment, powder recycling, easy to achieve automated production, easy to use, and the coating color is diverse, which can meet the requirements of different weather resistance. However, there are often some defects in the electrostatic powder spraying of aluminum profiles, which affect the appearance quality and performance of the products.
First, the application advantages of aluminum profiles in building doors and Windows
At present, the building doors and Windows on the market mainly include aluminum alloy doors and Windows, plastic steel doors and Windows, solid wood doors and Windows, aluminum wood composite doors and Windows. Among them, aluminum alloy doors and Windows account for more than 60% of the entire market, plastic steel doors and Windows account for about 30%, the market share of aluminum alloy doors and Windows is obvious, and the market application is more extensive. This puts forward higher requirements for the performance of aluminum alloy doors and Windows, and now many real estate companies are aware of the importance of the performance of doors and Windows, and ensure the overall performance of doors and Windows by specifying high-quality accessories such as aluminum profiles, glass, hardware, and rubber strips.
Second, the quality identification of aluminum alloy building profiles
At present, aluminum alloy profiles are more and more widely used in the building door and window curtain wall industry, and all kinds of aluminum profiles on the market are flooded with the market, which is mixed with good and bad quality, so that customers have a feeling of having no way to start in material selection. Therefore, it is very important to distinguish the advantages and disadvantages of aluminum profiles to ensure the quality of doors and Windows and the quality of the project. Here is a brief introduction
Third, the method of identifying the advantages and disadvantages of aluminum profiles:
1, check whether the wall thickness of the profile meets the requirements of the national standard GB8478, and the wall thickness of the profile that is not up to the standard affects the corrosion resistance and weather resistance.
2, check whether the raw and auxiliary materials used meet the requirements of national standards, non-standard raw and auxiliary materials affect the comprehensive performance of profiles.
3, check the smoothness of the profile, whether there is an obvious twist, the deviation is too large affect the assembly of doors and Windows curtain wall, and then reduce the sealing performance of doors and Windows curtain wall products.
4, detect the coating thickness of the surface treatment, etc., the film thickness should meet the film thickness requirements of GB8478 for various surface treatment methods.
5, the surface of the profile is not allowed to have cracks, burrs, bubbles, corrosion, the damage of the profile surface film layer, seriously reduce the corrosion resistance of the profile.
6, the surface of the profile is not allowed to have obvious scratches, pits, bruises, spots, peeling and other defects, otherwise affect the appearance of doors and Windows, curtain walls.
7, the same batch of profiles are not allowed to have different shades of two colors. See whether the color difference size is within the standard range, if the color difference is too large, it should not be used, otherwise it will affect the appearance and decorative effect.
8, whether the weatherability of the profile meets the requirements of GB5237, the weatherability of the profile is related to the service life of the profile.
