A method for manufacturing a tempered vacuumed glass, comprising: manufacturing of a support point (2), and, over-tempering treatment, compounding, sealing, and vacuuming of plate glasses (4 and 7), a total of five steps, among which, in the sealing step, a lead-free low-melting point glass powder containing a shortwave infrared-absorbing material is applied around a gap (3) between two sheets of over-tempered glasses (4 and 7) that are joined together, which are then introduced into an edge-sealing furnace to melt the lead-free low-melting point glass powder containing the shortwave infrared-absorbing material by means of employing a shortwave infrared for heating, thus sealing the gap (3) between the two sheets of over-tempered glasses (4 and 7) that are joined together. Employment of the method allows for a shortened time during which the tempered vacuumed glass is heated in the edge-sealing process, while ensuring the tempered strength of the glass. |
