Is the thermal stress in the glass curtain wall really the cause of glass breakage?
[China Glass Network] Thermal stress is an important cause of glass curtain wall breakage. There are many reasons for the heating of the glass curtain wall, but the main heat source is sunlight. When the sunlight shines on the surface of the glass curtain wall, the glass will be thermally expanded. If the glass is evenly heated, the glass edge and the central portion of the glass will expand evenly at the same time, but if the edge is And the inside of the glass is unevenly heated, and tensile stress is generated inside the glass. When there are cracks or micro cracks on the edge of the glass, these defects are easily affected by thermal stress. As the temperature difference increases, the thermal stress causes the crack to gradually increase. Big causes the glass to break. The solution is to first finish the edge of the glass, using fine-edged or polished edges to reduce the presence of micro-cracks; secondly, to temper the glass to enhance the glass's ability to resist temperature changes; the third is in the glass During processing, handling, and installation, the glass must be properly protected. Be careful not to collide and rub the edge of the glass with other hard objects. Strictly follow the operating procedures, especially during the installation process. If the frame is not suitable (too small or distorted) Deformation), be sure not to pinch the corners of the glass with pliers, be sure to correct the frame to fit the size of the glass.
