Abstract

The invention discloses a vacuum glass laminating, stacking and edge-sealing method. The method comprises the following steps: 1) a lamination step; 2) a treatment step after lamination; 3) a stacking step: stacking vacuum glass semi-finished products after lamination on a bracket layer by layer, and arranging a parting strip at the bottom of each group of vacuum glass after lamination, wherein each parting strip is a hollow tube or angle or an inorganic strip or rope with good heat conduction and high temperature resistance; 4) a high-temperature edge-sealing step: heating to a low melting point in a furnace, melting glass powder, further cooling, and taking out of the furnace, wherein the heat insulation time in a high-temperature zone in the furnace is prolonged by 5-30min in comparison with a single layer when every one layer of the glass is increased on the bracket; and 5) a vacuum edge-sealing step. According to the method disclosed by the invention, multiple layers are stacked and edge-sealed, the multiple layers of glass are longitudinally arranged and separated by utilizing the parting strips, the production efficiency is simultaneously improved by 2-5 times by heating treatment, and the heating time is correspondingly prolonged when every one layer is increased, so that the production quality can be ensured, the production efficiency is greatly improved and the energy consumption is simultaneously increased by less than 20%.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a vacuum glass stacking and edge sealing method. Background technique [0002] In the past ten years, the demand for thermal insulation, energy saving and sound insulation of buildings has promoted the development of vacuum glass production technology. Most existing vacuum glass manufacturing methods are to support and isolate two layers of flat glass, seal the circumference to form a cavity, and obtain a vacuum cavity through steps such as sintering, vacuuming, and sealing. Due to the elimination of gas conduction and convection, vacuum glass has excellent heat insulation and sound insulation properties. It has become a subject of people's research while being widely used. At present, dozens of new utility and invention patents for vacuum glass have been disclosed in China. . [0003] In the edge banding process, the conventional vacuum glass edge banding is plac...
