1. Production aspect: Due to the coating process, some needle-like film shedding, also known as pinholes, may occur during production, which is inevitable in the sputtering coating process itself. In addition, due to the original coated sheet itself or the cleaning of the equipment, it is also possible for the film to fall off.
2. Film shedding during transportation: After the glass is unpacked, moved or cut, no padding materials are placed between the glass sheets as required or the padding is not uneven or sufficient, causing direct contact between the glasses. During handling or transportation, this leads to direct relative friction between the glass and the glass film surface, resulting in film shedding. This kind of film peeling is usually in the form of dots or clusters. You can feel or check for friction marks by hand or with inspection equipment.
3. Corrosive film peeling: During the cutting, stacking, construction, use or cleaning of the glass film surface, due to cross-construction or the use of incorrect methods, the glass film surface comes into contact with acids, alkalis or oxidizing substances, etc., causing the glass film surface to be contaminated and corroded, resulting in film peeling. This kind of film peeling usually leaves traces of corrosive substances on the peeling surface or at the site.
Precautions for glass installation by Suzhou tempered glass manufacturers
For instance, during the installation of glass, it must be kept at a certain distance from metal frames or other metal objects. It is strictly forbidden for the corners of the glass to directly touch the metal frame in any direction or for the reserved gap to be too small. It is even more unacceptable to place the glass directly on the metal frame as in the installation of ordinary white glass. Otherwise, due to the heat absorption effect of the coated glass, it will expand, which will inevitably lead to the breakage of the glass.
