Do you really know how to clean the exterior glass of a building?

As a light-transmitting and wind-shielding material, glass is widely used in the construction industry. In the past, glass was mainly used for daylighting, but modern glass will be mainly used for decoration. Therefore, a large number of colored glass and special-shaped glass are used, which shows the important position of glass materials in the construction industry. However, if you still don't know how to clean the exterior glass of the building, do you still want the exterior glass?

Glass is made of quartz sand and alkali. After melting and cooling, the viscosity continuously increases to form a continuous three-dimensional network. Each cation in the structure is surrounded by oxygen ions with a certain coordination number. The cation has a large field strength, which is in an equilibrium state inside the glass, but is in a non-equilibrium state on the glass surface. It manifests as surface force, which makes the glass surface easy to interact with the surrounding medium. In addition, the surface of some glass is spongy with fine lines, and it is easy to adhere to dirt. In particular, the attached dirt invades the inside of the sponge, causing a chemical reaction to form dirt that is more difficult to remove.

Due to the surface force and surface activity displayed by the glass itself, it is easy to chemically react with the active groups of organisms and other organic substances. The surface causes corrosion, and the alkali resistance of the glass is very poor, and it is very susceptible to the corrosion of alkaline media. All of these have caused the glass to be easily contaminated. Especially the exterior glass on high-rise buildings has a lot of pollution media, strong sunlight, endless day and night trading and temperature changes, and the environment is very harsh.

Because glass is a brittle material, it is mostly embedded in a metal or wooden (or plastic, etc.) frame when used, and sealed with rubber or adhesive (such as putty) for waterproofing. Ordinary glass can be made into architectural glass of different colors after coating, and sometimes the color and pattern of ordinary glass can be changed by filming. All of the above contents should be taken into consideration when cleaning the exterior glass of the building.

Generally speaking, the glass surface is a non-polar hydrophobic surface. When cleaning the exterior wall cleaning company, the wetting of the surface should be considered first, and a well-wetting surfactant or organic solvent should be selected. Secondly, the water-repellent properties should be restored after washing. The use of some chemical components with strong water repellency and light transmission and brightening, so there is a kind of glazing cleaner product, which does not leave traces (such as film, spots, lines) on the glass surface after washing, and does not damage the glass itself and the frame. The technical requirements of glass cleaner for building exterior walls must be considered:

1. It has a good cleaning effect on the surface of the glass, leaving no traces, and no damage to the glass and the coating.

2. The functional glass cleaner should make the cleaned glass bright, water-repellent, and anti-fogging.

3. Cleaning the glass roof should effectively remove the deposited dust, and cleaning the vertical glass surface can wet and remove dirt in an instant.

4. The cleaning cost is low, the surrounding environment is not polluted, and the cleaning agent is harmless to the human body.
