How to avoid corrosion and prolong life of aluminum veneer curtain wall

　　铝单板作为近年来我国大力发展的一种新型环保建筑材料，具有耐酸碱、耐腐蚀、耐紫外线、使用寿命长等优点，广泛应用于室内外墙装饰。其中，铝单板作为幕墙安装在外墙上，经历各种天气，如何延长aluminum veneer curtain wallThe service life?

1. During the construction process, the aluminum veneer profile is not used for necessary maintenance with maintenance tape. During the construction process, this abnormal corrosion appearance should be avoided due to the transfer forming the corner bump/bump coating of the profile. In the process of aluminum curtain wall construction, the maintenance of aluminum veneer curtain wall profile is very important. In the manufacturing process, care must be taken to avoid bumps/bumps on the surface coating of the profile. Before manufacturing the aluminum ceiling product device, the adhesive tape must be maintained around the outer frame. After installation on the wall, stop trampling. When scaffolding needs to be placed, wooden boards and other materials should be used to maintain the curtain wall frame.

2. The corrosion direction of curtain wall with abnormal corrosion appearance is long-term water seepage. Wet parts, so the construction process of aluminum veneer curtain wall requires waterproof and moisture-proof methods. Generally, the gap between the aluminum veneer curtain wall frame and the wall hole should be soundproof and moisture-proof, non-corrosive materials, such as polyurethane PH foam filling materials to avoid treatment; if cement mortar is selected for filling, Waterproof mortar should be selected, and sea sand is prohibited from being used as waterproof mortar.

3. Regarding abnormal corrosion, we advocate that the wall construction mortar should not use sea sand as much as possible. If the area really needs to be used, we advocate referring to the sand GBT14684-2001 for construction, cleaning with water, reducing the chloride ion to ≤ 0,06% or less, and carrying out anti-corrosion treatment on the aluminum veneer profile and wall opening of the curtain wall during the construction process. Generally speaking, if the anti-collision and waterproof method is used, it can play an anti-corrosion effect. Changing the asphalt is also a feasible method.

4. When the fluorocarbon aluminum veneer is delivered, the profile should be cleaned, the maintenance film paper should be torn off, and the cement and lime mortar attached to the appearance of the profile during wall construction should be removed. Dust is usually cleaned with a neutral detergent, or the attached dust is removed with a fiber brush. Sandpaper and steel wire ball brushes must not be used for polishing.
