Information

The strength, stiffness and sealing performance of insulating glass are the main factors affecting the bearing performance of insulating glass. This is directly related to the thickness of the glass and the installed thickness of the spacer layer. The thickness of insulating glass is usually measured with an Insulating Glass Thickness Gauge. First briefly introduce the hardness, bearing capacity, test method and installation of insulating glass.

1. Strength and stiffness of insulating glass

Strength refers to the ability of glass to resist external loads, and stiffness refers to the ability of glass to withstand deformation. Under the action of external load, the load directly distributed to each piece of glass determines the bearing capacity of insulating glass. Given the glass material, according to the glass strength design theory, the breaking strength of the original glass plate is determined. To improve the bearing capacity of insulating glass, it is necessary to reduce the surface bending and tensile stress of the glass under the same load. This is related to the size of the original insulating glass sheet and the thickness of the insulating layer.

2. Bearing characteristics of insulating glass in the state of failure of the hollow layer

In the case of a gas seal in the hollow layer, the gas transfer function can transfer part of the external load to another piece of glass. However, if the gas layer leaks, the gas in the hollow layer will completely lose the function of transferring the load. Then the load on the insulating glass is completely borne by the directly stressed glass sheet. Obviously, the bearing capacity of insulating glass will be significantly reduced.

3. Method and device for on-line detection of hollow layer failure

After the sealing performance of the insulating layer fails, the load-bearing performance of the insulating glass changes. Therefore, a method of applying a concentrated force in the center of the glass plate and observing the deformation of the inner and outer sheets of the insulating glass or the change of the thickness of the hollow layer is proposed to identify whether the hollow layer is sealed. In order to detect the sealing performance of the insulating glass layer online, the detection device mainly includes a force application device, an insulating glass deformation observation device and a glass thickness gauge.

By applying a concentrated force to one side of the insulating glass during use, record the deflection value of the center of the inner and outer sheets of the insulating glass or the thickness of the hollow layer, which can be observed by a displacement sensor The deformation of the insulating glass is measured, and the thickness of the hollow layer is measured by an insulating glass thickness gauge.
