With the development of construction, automobile, decoration, furniture, information industry technology and other industries and the improvement of people’s requirements for living space environment, functional processing products such as safety glass and energy-saving insulating glass have been widely used. Due to the lack of publicity, many people think that vacuum glass and medium vacuum glass are the same thing, but this is not the case.
In terms of structural composition, vacuum glass and insulating glass are still very different. First of all, the gap between the two pieces of vacuum glass is a vacuum layer, which can be simply understood as no gas, while the gap between the two pieces of insulating glass is dry air or inert gas. This difference also causes the gap of vacuum glass to be only 0.1-0.2mm, while the minimum gap of insulating glass is 6mm, so the thinnest vacuum glass can be 6mm, and the thinnest insulating glass needs to be 12mm. The surrounding of vacuum glass is sealed with metal solder or low melting point glass, while the hollow glass is sealed with organic glue.
The following steps can help you quickly identify vacuum glass:
- When the glass is closely observed, evenly distributed tiny dot supports can be seen between the two pieces of glass;
2. There is an air outlet and a protective cap at the corner of the glass (except for the flat seal);
3. The four sides are sealed with solidified metal solder or low melting point glass; the glass thickness is about 6mm-8mm.
