1. a kind of tablet toughened vacuum glass, including upper glass and lower glass, it is characterised in that:

  • The upper glass and the weldering of lower glassThere is edge band frame on the periphery of junction, and the edge band frame is that melting temperature is imprinted on institute for 550-750 DEG C of cryogenic glass powderThe fin for being formed on glass and lower glass and being raised in glass surface is stated, it is molten in the high temperature action lower sealing edge bar frame softening of annealing furnaceMelt together with glassy bond, carry out tempering processing immediately, obtain the upper and lower tempered glass with edge band frame;

    The upper glassThe edge band frame of glass and lower glass is mutually entrenched togather, and labyrinth sealing is carried out to the vacuum layer of the vacuum glass;

    It is describedIt is 430~450 DEG C of low temperature glass solder to have melting temperature between edge band frame, and the periphery of the upper glass and lower glass passes throughThe edge band frame and low temperature glass solder being entrenched togather weld together in vacuum sealing side furnace;

    The edge band frame can limitRandom flowing after low temperature glass solder processed fusing, make edge sealing neatly good-looking, and plays good supporting role, makes low temperatureThe certain thickness of glass solder holding, strengthen sealing effect;

    The vacuum of a closing is formed between the upper glass and lower glassLayer, there is the supporter in lattice arrangement in the vacuum layer.
