Abstract
The present invention relates to a method for glass fusion. The method includes the following steps: laminating the glass; microwave processing the glass after the lamination processing; and welding the glass after the microwave processing. First, the glass is laminated to enhance the surface interface activity of the glass and promote the bonding between the glass interfaces; then the laminated glass is subjected to microwave treatment, the microwave penetrates into the glass, and the interaction between the microwave and the glass generates friction. It causes the temperature of the glass to rise, so that the inside and outside of the glass are heated and heated almost at the same time, forming a body heat source state, and the heating inside and outside the material is uniform; no additional pressure is required, and the glass interface will diffuse freely during the microwave treatment process, thus achieving tightness between the glasses. At the same time, the high temperature generated by the microwave can make the interface group of the glass group have a weak connection. After high temperature welding, the silicon-oxygen bond between the glasses can be promoted, and the tight connection of the glass sheets can be realized. Effect.
Description
technical field [0001] The invention relates to the field of glass manufacturing, in particular to a method for glass fusion. Background technique [0002] Glass is more and more widely used in daily life. With the increasing demand for the appearance and function of household appliances and decorations, and the maturity of related technologies, multi-layer glass structure products also emerge as the times require. [0003] The existing glass fusion methods are mainly adhesive bonding, laser-assisted fusion bonding or low-melting glass powder fusion bonding. For example, the welding methods mentioned in the patents CN108262679A and CN108381053A have high requirements on equipment and high cost; the flux distribution is uneven, and the seams are easy to fall off during the tempering process after welding, resulting in low product yield. SUMMARY OF THE INVENTION [0004] Based on this, it is necessary to provide a glass welding method with simple process, low cost, good wel...
