ã€China Aluminum Industry Network】 For the decoration of the owners, not only the quality of the decoration required but also requires beauty. Today, most windows are made of aluminum alloy doors and windows, but after prolonged wind and sun exposure, aluminum alloy doors and windows are prone to rust. This requires the decoration owner to carefully choose aluminum doors and windows. If you want to choose a good quality aluminum doors and windows, we must know the working principle of aluminum doors and windows and the reasons for rust.
The doors and windows of the building not only have the function of ventilation, light and rain, but also are the important facades of the building, embodying the style of the building and the architect's personality. Since the iron doors and windows were “laid offâ€, aluminum doors and windows were favored by consumers because of their good strength, light weight and difficulty in “rustingâ€.
Recently, however, the problem of “rusting†of aluminum doors and windows has caused both architects and owners a big headache. A beautifully built building has even begun to “rust†and even affect the appearance of buildings, even without aluminum doors and windows. The reason for the “rusting†of aluminum doors and windows is very complex and is generally considered to be related to the aluminum protective film. About 80% of the aluminum profiles on the market today are produced by anodizing a protective film, an oxide film. The thickness and firmness of the oxide film are the key to aluminum wear and corrosion resistance.
Regular, reputable professional manufacturer, the aluminum oxide film requirements are very high, oxide film thickness, hardness, firmness than the national standard requirements are even more stringent for many years by the consumer's welcome and trust. However, due to the need of vicious price competition, many manufacturers have done a lot of hands and feet on the oxide film, especially many aluminum manufacturers in Huangshi, Hubei Province, the thickness of the oxide film is far from the national standard requirements, and some even do not oxidize Membrane; At the same time, due to the use of poor raw materials, resulting in oxide film hardness is too low, the firmness is poor, easy to fall off.
For our province, coastal cities such as Yantai, Qingdao, and Rizhao have high salt and high humidity because of the high humidity in the air. If the decoration owner chooses doors and windows with poor purity of aluminum, the aluminum oxide film will fall off or the oxide film will be insufficient. Rusty. Therefore, to remind everyone to do a good job in the purchase of aluminum doors and windows do a good job, to learn about aluminum doors and windows of knowledge, or ask a professional person to accompany the purchase.
