The doors and windows of the building not only have the function of ventilation, ventilation, rain and rain, but also the more important facade of the building, reflecting the style of the building and publicizing the personality of the architect. Since the iron doors and windows have been " laid off", aluminum doors and windows have been favored by consumers because of their strength, light weight and not easy to "rust".
But recently, the "rusting" problem of aluminum doors and windows has caused great headaches for architects and owners. A beautiful building that has not yet entered the aluminum doors and windows has begun to "rust" and even affect the appearance of the building. The reason for the "rusting" of aluminum doors and windows is very complicated and is generally considered to be related to the protective film of aluminum. At present, about 80% of the aluminum profiles on the market are formed by anodizing to form a protective film - an oxide film. The thickness and firmness of the oxide film are the key to wear resistance and corrosion resistance of aluminum.
Regular and reputable professional manufacturers have high requirements for the oxide film of aluminum profiles. The thickness, hardness and firmness of the oxide film are stricter than those required by the national standard. They have been welcomed and trusted by consumers for many years. However, many manufacturers have done a lot of work on the oxide film due to the need of vicious price competition, especially many aluminum manufacturers in the Huangshi area of ​​Hubei. The thickness of the oxide film is far from the national standard, and some even do not oxidize. At the same time, due to the use of poor raw materials, the hardness of the oxide film is too low, the firmness is poor, and it is easy to fall off.
For our province, Yantai, Qingdao, Rizhao and other coastal cities, due to high air humidity and high salt content, if the decoration owner chooses the doors and windows with poor purity of aluminum, the aluminum oxide film is detached or the oxide film is not enough. Rusty. Therefore, remind everyone to do a good job in the purchase of aluminum doors and windows, do a good understanding of the aluminum door and window related knowledge, or ask a professional person to accompany the purchase.
