Abstract
The invention relates to a glass welding method. The method comprises the following steps: carrying out laminating treatment on glass; carrying out microwave treatment on the laminated glass; and carrying out welding treatment on the glass subjected to microwave treatment. Firstly, laminating is performed on the glass to enhance the surface interface activity of the glass and promote the combination between glass interfaces; microwave treatment is conducted on the attached glass, microwaves penetrate into the glass, the temperature of the glass is increased through friction generated by the interaction of the microwaves and the glass, the interior and the exterior of the glass are almost heated at the same time, a body heat source state is formed, and the interior and the exterior of the material are heated uniformly and consistently; extra pressurization is not needed, and the glass interface can be freely diffused in the microwave treatment process, so that the effects of tight attachment and no bubble between the glass are realized; and meanwhile, the high temperature generated by the microwaves can enable the interface group of the glass group to have weak connection, and after high-temperature welding, silicon-oxygen bond combination between the glass is promoted, so that the effect of tight connection of the glass plates can be realized.
Description
technical field [0001] The invention relates to the field of glass manufacturing, in particular to a glass fusing method. Background technique [0002] Glass is used more and more widely in daily life. With the improvement of people's demand for the appearance and function of household appliances and decorations, and the maturity of related technologies, multi-layer glass structure products have also emerged as the times require. [0003] The existing glass welding methods are mainly glue bonding, laser-assisted welding or low-melting point glass frit welding. For example, the welding method mentioned in patents CN108262679A and CN108381053A has high requirements on equipment and high cost; the flux is not evenly distributed, and the seam after welding is easy to fall off during the tempering process, resulting in a low product yield. Contents of the invention [0004] Based on this, it is necessary to address the above-mentioned problems and provide a glass welding metho...
