The vacuum glass is a new generation of energy-saving and environment-friendly glass, and has obvious product performance advantages compared with commonly used glass products such as common single-layer toughened glass, double-layer hollow glass and the like. The composite material has the advantages of sound insulation performance, heat preservation performance and anti-condensation function, has high-efficiency energy-saving effect and environment pollution reduction effect in wide fields of buildings, refrigeration and heating electric appliances, traffic and the like, and has very large potential and application market.
The vacuum glass is essentially formed by packaging two pieces of common toughened glass through an airtight sealing material, wherein the airtight sealing mostly adopts low-temperature glass powder or flexible metal soft solder, a vacuum layer with the thickness of 0.3-0.4 mm is formed between the two pieces of glass through vacuum, metal supports are arranged between the two pieces of glass in an array manner to offset atmospheric pressure, and an air suction opening is reserved on one piece of glass so as to conveniently suck air from the vacuum layer to form vacuum. In the prior art, the low-temperature glass powder sealing technology for vacuum glass is less adopted due to the problems of overhigh temperature and reduced mechanical property of the vacuum glass, and the flexible metal soft solder sealing technology has the defects that the components of a sealing layer are complex because metal materials and glass are different from homogeneous materials and extra materials are required to be added into the sealing layer, so that the thermal expansion coefficients of all layers of the sealing material are not matched, great residual thermal stress can be generated in the sealing treatment process, and the mechanical strength of the vacuum glass can be influenced. In the vacuumizing process, an air pumping opening with the thickness ranging from a few millimeters to 1-2 millimeters is reserved in the prior art, or the vacuum degree of a vacuum layer of the vacuum glass is realized by vacuumizing through a glass tube or slowly exhausting the vacuum glass in a vacuum environment, and finally the air pumping opening is sealed off. The process is an important reason for the low production speed of the traditional vacuum glass, the extraction opening is too small, the conductance is very large during the extraction, the extraction speed is very small, the production period of the single piece of vacuum glass is very long, even the extraction time of one hour is calculated, and the process is not suitable for large-scale production. Meanwhile, after the vacuum degree of the vacuum layer is reduced to a certain value, the free path of gas molecules is large, the gas molecules are difficult to diffuse out from a small air suction opening, the vacuum degree far away from the air suction opening is greatly different from the vacuum degree near the air suction opening, and the vacuum degree of the vacuum layer cannot be reached, so that the product performance of the vacuum glass is greatly influenced. The reserved air extraction opening is obtained by mechanically drilling the common float glass before tempering, and microcracks inevitably occur at the edge of the air extraction opening, so that the air leakage risk is great in the later period.
