Understanding of glass curtain wall cleaning

Glass is a very familiar building decoration material, and it adds brilliance to the building with its unique charm. Glass curtain wall is a kind of enclosure structure installed on the outside of the main structure of the building, hanging like a curtain on the outer eaves of the building to become a new type of wall It is mostly used for exterior wall decoration of high-end properties. Its structure and craftsmanship are complicated, and the cleaning profession is difficult and professional. It should be completed by a high-level and high-quality aerial work team.

      In cities, it is inevitable that heavy dust is often hung on the glass curtain wall. Especially in a windy and sandy day, after this kind of weather, the glass curtain wall is often unbearably dirty. Today, I will introduce the cleaning method of the glass curtain wall, so that everyone who has a glass curtain wall can have a reference.

　　 Glass curtain wall cleaning method

　　(1) Wash with solvent. Use solvents such as xylene, toluene, inorganic alcohol or ether to remove grease and glazing materials before cleaning and rinsing. Be careful not to use too strong solvents to avoid damage to the sealant of the fixed glass.

　　(2) Clean and rinse normally. The glass should be washed, rinsed and dried frequently, especially during the construction period, should use soft, clean, dust-free cloth and neutral soap, paint detergent or slightly acidic cleaning solvent. After washing, rinse with clean water immediately, and then wipe off the remaining water with a clean squeegee. Because fingerprints, oil stains, stains, dust, scum, sealant residues, scratches, and any surface scratches on coated glass are more conspicuous than on ordinary glass, we are managing and cleaning the coating Be extra careful when glazing. Therefore, the coated glass may require frequent cleaning during the entire project, and interlayer plates should always be used between the coated glass window panels.

　　(3) Surface damage. Contaminated by concrete, the alkali-containing or fluorine-containing substances sometimes released from concrete or building masonry during storms may stain or corrode the glass. The concrete structure in front of the window arch should be designed so that the dripping water will not drip. Onto the glass. When manufacturing precast slabs and other concrete wall materials, they should be fully mixed to make them uniform hydrates and fully solidified. The surface treatment of concrete (acidification sandblasting, rock drilling, grouting, waterproofing materials, etc.) should be carried out It is finished before installing the glass, and the broken pieces should be removed.

       Exterior wall cleaning operation method 　　

1. Hanging board at high place (rope method): Workers use the hanging board (rope) to slide down to the designated position for construction operations. This construction method has the characteristics of convenience, flexibility, and high safety factor. At the same time, it occupies less resources, which can minimize the impact on the daily work and life of the owner.

2. Hanging basket method: erecting a hanging basket on the top of the building to transport workers to a designated location for construction operations. This construction method has lower cleaning efficiency and higher cost.

3. High-altitude spider truck: Use platform equipment such as spider trucks and lift trucks to transport workers to designated locations for construction operations. This construction method has relatively large limitations, and is generally suitable for difficult projects below 36 meters. Because of the high cost, it is rarely used.

4. Track window cleaner: Some high-rise buildings are reserved for track window cleaner. This construction method is the same as the hanging basket method, but it is easy to move.

5. Indoor double-sided wiping method: some glass exterior windows are cleaned with double-sided magnetic glass squeegee. This method can be operated indoors, but the efficiency is low and the reliability is poor. It is used more in the south. Due to the strength of the magnetic force, it has almost no effect on the hollow double-layer glass.
