5th step, loads brazing metal in the bleeding point of above-mentioned double glazing, and sends in vacuum oven; Described vacuum sole is vacuumized, limit heating, be evacuated to below 0.1Pa, be warming up to more than the temperature of fusion of brazing metal, brazing metal is fused into liquid, and liquid retention is between the sealed strip of lower-glass, the sealed strip of upper glass also floods in a liquid, and liquid is by bleeding point self-sealing; Stop heating, with stove cooling, brazing metal solidifies and realizes airtight sealing to bleeding point afterwards, opens vacuum oven, takes out convex surface vacuum glass;
6th step, puts into seal gum and protective casing in the bleeding point of convex surface vacuum glass, at the place suitable for reading Paste Product trade mark of protective casing.
8. the preparation method of convex surface vacuum glass according to claim 7, is characterized in that described edge sealing stove once heats one to several piece convex surface vacuum glass.
9. the preparation method of convex surface vacuum glass according to claim 7, is characterized in that described edge sealing stove and accessory has basic heating system and hot spot system.
10. the preparation method of convex surface vacuum glass according to claim 9, it is characterized in that described basic heating system adopts one or several of Hot-blast Heating, resistive heating, Infrared Heating and far-infrared heating, described hot spot system adopts microwave heating or Infrared Heating mode.
