Fluorocarbon aluminum plate is a new type of environmentally friendly building material. The surface of a good curtain wall aluminum plate is generally pre-treated with chromium and then treated with fluorocarbon spraying. Polyvinylidene fluoride resin (KANAR500). It is generally divided into two coatings. Three coatings or four coatings. Fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain. Salt spray and various air pollutants, excellent cold and heat resistance, can resist strong ultraviolet radiation, can remain non-fading for a long time. No powder, long service life.
First of all, friendly reminder:
1. When choosing and purchasing aluminum veneer manufacturers' products, give priority to brand-qualified products.
2. Generally speaking, qualified aluminum veneer manufacturers are usually strong, with strong follow-up research and development capabilities and professional design departments.
3. There are many domestic sales outlets and strong product market competitiveness. At the same time, manufacturers provide a variety of complete product promotional materials. Product certificates. Quality certificates. As well as installation instructions, and guaranteed after-sales service.
So, how to better prevent the curtain wall aluminum plate from being corroded?
1. During the equipment construction process, the repair tape of the aluminum veneer profile was not left; during the construction process, the angles and angles of the profile were impacted and broken during the construction process. Therefore, the maintenance of fluorocarbon curtain wall aluminum profiles is particularly important during the construction process of this abnormal corrosion phenomenon. During all operations during the manufacturing process, care should be taken to avoid the surface coating of the profile. Before installing the prefabricated aluminum ceiling product, the external frame needs to be closed for maintenance. Self-adhesive paper should be installed on the wall to prevent people from stepping on the wall. When scaffolding is required, wood and other materials should be used to maintain the curtain wall frame.
2. The corroded part of the curtain wall with an abnormal corrosion appearance is a long-term water seepage part. Therefore, the curtain wall aluminum plate must be waterproof and moisture-proof during construction. In general, the spacing between the curtain wall aluminum plate frame and the wall hole should be selected. Sound insulation materials should be avoided. Moisture-proof and non-corrosive materials such as PH polyurethane foam filler ester foam filler. If cement mortar is used to fill the gap, waterproof mortar should be used, and sea sand should not be used for waterproof mortar.
3. For abnormal corrosion, it is recommended not to use sea sand in the wall construction mortar as much as possible. If this area needs to be used, it is recommended to refer to the construction sand of gbt14684-2001, rinse with water, reduce the chloride ion to below 0.06%, and perform anti-corrosion treatment on the aluminum veneer profiles and positions of the curtain wall during construction. If anti-collision and waterproofing measures are taken to achieve the anti-corrosion effect, the wall opening will generally be exposed, and replacing the asphalt is also a more feasible method.
4. When delivering the construction, clean the profile, remove the maintenance film, and remove the cement lime mortar attached to the surface of the profile during wall construction. Usually, a neutral detergent is used to clean dust and dirt. A fiber brush can also be used to remove attached dust. Grinding with sandpaper or steel ball brush is not allowed.
