Problems solved by technology

[0003] Tempered glass is usually used as two pieces of flat glass to form a vacuum glass. In the process of sealing the two pieces of tempered glass, long-wave infrared is usually used to heat the lead-free low-melting point glass powder to melt the lead-free low-melting point glass powder to seal the two pieces. However, due to the high absorption rate of long-wave infrared rays by glass, the surface temperature of tempered glass will reach the annealing temperature of tempered glass by this heating method, making tempered glass annealed into ordinary glass. In order to control tempered glass The surface temperature of the tempered glass is lower than the annealing temperature of the tempered glass, and the heating time of the lead-free low-melting point glass powder is about 12 hours. Too long heating time leads to low production efficiency of the vacuum glass

Embodiment Construction

[0026] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details.

[0027] It should be noted that flat glass becomes tempered glass or over-tempered glass after tempering or over-tempering. In essence, flat glass, tempered glass and over-tempering are the names of the same glass in different processing processes. Therefore, for the convenience of expression , In the following description of the present invention, the reference numerals of flat glass, tempered glass and tempered glass are the same.

[0028] figure 1 shows the processing flow of tempered vacuum glass according to the present invention, Figure 2 to Figure 5 The structures of the tempered vacuum glass according to the embodiments of the present invention are shown respectively.

Abstract

The invention provides a production method of toughened vacuum glass. The production method of the toughened vacuum glass comprises five steps of manufacturing a supporting point, performing excessive toughening treatment on plate glass, compounding, sealing and vacuumizing, wherein in the sealing step, the periphery of the gap between two pieces of excessively toughened glass which are mutually combined is coated with lead-free low-melting-point glass powder containing an infrared material for absorbing short wave, and the two pieces of excessively toughened glass are conveyed into an edge sealing furnace to be melted by a short wave infrared heating method so as to seal the gap between the two pieces of excessively toughened glass. According to the production method of the toughened vacuum glass, the heating time of the toughened vacuum glass in the edge sealing process can be shortened and the toughening strength of the toughened vacuum glass is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vacuum glass manufacturing, and more specifically, relates to a production method of tempered vacuum glass. Background technique [0002] Vacuum glass is to seal the surroundings of two pieces of flat glass, vacuumize the gap and seal the air hole. Because the two pieces of flat glass that make up the vacuum glass are very thin, in order to achieve the balance of the pressure inside and outside the flat glass, a support point is often added between the two pieces of flat glass to support the glass under the pressure of the external atmospheric pressure. Its working principle is the same as The thermal insulation principle of the vacuum flask is similar. [0003] Tempered glass is usually used as two pieces of flat glass to form a vacuum glass. In the process of sealing the two pieces of tempered glass, long-wave infrared is usually used to heat the lead-free low-melting point glass powder to melt the lea...
