[China Glass Net] The main factors affecting the bearing performance of insulating glass are the strength of insulating glass, the rigidity of insulating glass and the sealing performance of hollow glass hollow layer. 1. Strength and stiffness of insulating glass The strength of the insulating glass refers to the ability of the insulating glass to resist the external load, and the rigidity refers to the ability of the insulating glass to bear deformation. Obviously, after the glass material is given, such as ordinary flat glass or tempered glass, the breaking strength of the original glass sheet is determined according to the glass strength design theory. Therefore, in order to improve the bearing capacity of the insulating glass, it is necessary to make the glass surface bending stress smaller under the same load, which is different from the original size of the insulating glass (length, width, aspect ratio and thickness of each original sheet). The thickness of the hollow layer is related to the load capacity of the insulating glass directly under the external load. 2. Bearing characteristics of insulating glass in the failure state of hollow layer In the case of a hollow gas seal, the gas transfer can transfer a portion of the external load to the other glass. However, when the gas layer leaks, the hollow layer gas completely loses the role of transmitting the load. At this point, the load on the insulating glass is completely borne by the piece of glass that is directly stressed. Obviously, the load capacity of the insulating glass at this time will be significantly reduced. 3. Influence of ambient temperature and pressure difference on bearing performance of insulating glass Even if it is not affected by external loads, due to the difference between the production environment of the insulating glass and the use environment, it will cause the expansion or contraction of the hollow glass hollow gas, which directly causes deformation and additional stress of the two original glass sheets. The two pieces of glass are rubbed against each other and even cause the glass to rupture. In summary, the bearing capacity of the insulating glass depends on the strength of the glass sheet, the rigidity and the sealing property of the hollow layer. Under uniform load, the forces on the outer and inner sides of the insulating glass are different. The outer glass is stressed, the back force is small, and the smaller the size, the more obvious. When the side length of the insulating glass is greater than 150 times of the thickness, the force of the double-sided glass tends to be close, and the hollow glass gas leakage deformation, the hollow glass bearing deformation performance The change is evident by applying a concentrated load to the insulating glass. Measuring the deflection of the inner and outer sheets or the thickness of the hollow layer can identify whether the hollow gas layer is well sealed. The test and on-site test results prove that the method and the detecting device can conveniently, quickly and reliably detect the sealing performance of the insulating glass.
