A method for testing the sealing performance of insulating glass in service

Abstract

The invention discloses a method for on-line detection of the sealing performance of insulating glass in service, which includes the following process: when determining the airtightness and leakage state of the inspected insulating glass, the hollow glass bears the deformation amount W tightness and W leakage under a certain force, and the on-site detection is also performed. Measure the bearing deformation of the inspected insulating glass under force W, compare the values, and which end the value of the W measurement is close to indicates which state the inspected insulating glass is close to, so as to evaluate the sealing performance of the inspected insulating glass hollow layer. Wherein, the applied force is at the center of the inner or outer sheet of the insulating glass, and the bearing deformation is the glass deflection value. W density and W leakage are determined by theoretical calculation or laboratory simulation measurement. The method of the invention has low test cost, is easy to realize on-line detection, and can evaluate the service health status of the insulating glass.

Description

technical field [0001] The invention relates to a detection technology for the sealing performance of insulating glass in service, and specifically relates to a method and device for online detection of whether the sealing performance of insulating glass is invalid. It utilizes the change in the load-bearing deformation performance of the inner and outer sheets of the insulating glass before and after gas leakage in the hollow layer of the insulating glass. A concentrated load is applied to the center of the insulating glass panel, and the deformation of the inner and outer sheets of the insulating glass is observed, so as to evaluate the sealing performance of the hollow layer of the insulating glass. Background technique [0002] Over the past ten years, comfort and nature, environmental protection and energy conservation have gradually become the principles of international architecture in the new century, and building energy conservation has become a worldwide trend.

Problems solved by technology

However, with the increase of the service life of the insulating glass, the hollow gas layer sealing layer (heat insulation function layer) of the insulating glass tends to experience continuous decline in function and even gas leakage, which leads to the failure of the insulating glass

Moreover, once the sealing layer of the insulating glass leaks, the insulating glass will become the same as ordinary glass and lose its energy-saving effect completely.

In particular, the gas in the sealing functional layer of insulating glass also plays the role of transmitting external loads. After the sealing layer fails, the load-bearing performance of the glass will be significantly reduced, which will affect the safe use of energy-saving glass.

During the service process, insulating glass is subject to environmental corrosion and external force and the continuous aging of glass structural materials. The failure or degradation of the sealing function layer of energy-saving glass is inevitable. The number of insulating glass in doors, windows and curtain walls in my country is huge. If these failed hollow glass The continued use of glass will not only cause energy-saving buildings to lose their energy-saving effect, but also cause problems such as the potential risk of falling off.
