Information

With the continuous improvement of the quality of life, insulating glass, as a high-performance glass product, has gradually gained a place in the glass market. Simply put, there is glass on both sides and an enclosed space in the middle filled with dry gas. This structure makes the traditional thickness measurement method inaccurate, so we usually choose a dedicated insulating glass thickness gauge for testing.

In modern society, it is easy to see insulating glass in libraries, exhibition halls, museums and other places. It often has excellent heat insulation and explosion-proof properties, can effectively refract light, has a strong sense of beauty and cleanliness, and is also a camouflage protection for indoor items and furniture. The light transmittance and explosion-proof performance of glass are often closely related to its thickness. Due to changes in physical factors such as external air pressure and temperature, the actual thickness of insulating glass will also change subtly. Therefore, it is very important to use an insulating glass thickness gauge. The insulating glass thickness gauge with high technical level can intelligently detect the thickness of insulating glass.

In theory, the principle of the insulating glass thickness gauge is: optical reflection, which can measure the thickness of one side of the insulating glass and read the dry gas inside the insulating glass thickness of. Compared with traditional glass measurement methods, this insulating glass thickness gauge can display data faster and with higher accuracy, which can be trusted by technicians. Its outstanding advantage is that the hollow glass thickness gauge can be used in occasions where ordinary measuring tools cannot or are difficult to operate.

The strength, stiffness and sealing performance of insulating glass are the main factors affecting the bearing performance of insulating glass, which are directly related to the thickness of the glass and the installation thickness of the interlayer. The thickness of insulating glass is usually measured with an insulating glass thickness gauge. 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 resist 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, the breaking strength of the original glass sheet is determined according to the glass strength design theory. In order to improve the bearing capacity of insulating glass, the surface bending and tensile stress of the glass must be reduced under the same load, which is related to the size of the original insulating glass plate and the thickness of the thermal insulation layer.

2. Bearing characteristics of insulating glass in the state where the insulating layer is damaged

In the case of an airtight hollow layer, the gas transfer function can transfer part of the external load to the other glass. However, if the gas layer leaks, the gas in the hollow layer will completely lose its function of transferring loads. Then, the load on the insulating glass is completely borne by the directly stressed glass plate. Obviously, the bearing capacity of insulating glass will be greatly reduced.

3. On-line detection method and device for hollow layer failure

After the sealing performance of the insulation layer fails, the load-bearing performance of the insulating glass changes. Therefore, it is recommended to apply a concentrated force in the center of the glass plate and observe the deformation of the inner and outer sheets of the insulating glass or the change of the thickness of the thermal insulation layer to determine whether the thermal insulation 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.
