Abstract
The invention discloses a method for manufacturing vacuum glass based on a novel edge sealing technique and a negative pressure kettle. An edge sealing material applied to the substrate glass is provided with clearances at intervals, the clearances are matched with the pores generated by semi-solidifying to greatly enhance the vacuumizing efficiency; and since more than three solvents with different gasification points are added into the edge sealing material, the solvents are volatilized stage by stage while the temperature gradually increases, so that the edge sealing material can form the honeycomb pores more easily in the semi-solidified state. Before edge sealing, the edge sealing material is solidified to achieve the porous semi-solidified state, and the effect can be detected at this time, thereby removing the unacceptable product in time. By using the edge sealing technique to produce the vacuum glass, the method saves the air nozzle slotting arrangement, vacuumizing, air nozzle fusion sealing and other long-time-consumption steps which can easily damage the product, and greatly enhances the yield and production efficiency of the vacuum glass. The vacuum glass manufactured by the technique has the advantages of higher product quality and higher vacuum degree.
