The formation of the low latitude glass of described single low dead level adopts one-step method to form, and described one-step method refers to that the edge sealing of low latitude glass and high-temperature exhaust air complete in high temperature edge sealing stove simultaneously, and can carry out batch process to low latitude glass.
Described one-step method further comprises the steps:
To between two edge band frames of lower-glass, pack solder into, and described two glass consistencies from top to bottom are stacked together, between two glass, leave exhaust passage, then send in high temperature edge sealing stove; High temperature edge sealing stove heating is made in stove more than temperature rises to the melt temperature of solder, to reach edge sealing temperature; Solder is melted into liquid, and under the effect of glass self gravitation, upper and lower edge band frame is entrenched togather mutually; Stop heating, reduce furnace temperature to room temperature, described solder welds together bubble-tight upper and lower glass, thereby obtains needed convex surface tempering low latitude glass.
It is as follows that the one-step method of described two low dead level convex surface tempering low latitude glass forms step:
To in the middle of two edge band frames of lower convex glass and middle plate glass solder side, pack solder into, and three glass consistencies from top to bottom are stacked together, between glass, leave between two exhaust passage, then send in high temperature edge sealing stove; High temperature edge sealing stove heating is made in stove more than temperature rises to the melt temperature of solder, to reach edge sealing temperature; Solder is melted into liquid, and under the effect of glass self gravitation, upper and lower edge band frame is entrenched togather mutually; Stop heating, lower the temperature with stove, solder hermetic welds together three blocks of glass, opens fire door and obtains required convex surface tempering low latitude glass.
Described edge sealing temperature is preferably 180～480 DEG C, more preferably 260～320 DEG C or 320～470 DEG C.
In the time that the melt temperature of described solder is 320～470 DEG C, the problem of annealing because welding temperature is too high for solving safety glass, high temperature edge sealing stove can have basic heating system and local heating system, basis heating system can adopt the mode of resistance heated as heating wire, electrothermal tube, electric hot plate etc., by high temperature edge sealing furnace interior and glass heats to basal temperature; The modes such as recycling resistance heated, infrared heating, LASER HEATING, Electromagnetic Heating, heating using microwave are that local heat is carried out in edge sealing position to the periphery of glass, reach the object that at short notice solder is heated to melting.

Because utilization has the mould of upper and lower mould, glass clamp relied between upper and lower mould to the moulding of exerting pressure, so convex surface safety glass has more regular shape, and prevent the distortion in toughening process, so edge sealing is simpler, sealing property and intensity are also higher. Because high temperature edge sealing stove and accessory has basic heating system and local heating system, can make the temperature of glass edge be rapidly heated to welding temperature, and tempering or semi-tempered glass are under lower basal temperature, in the long period and higher local temperature, in shorter time, phenomenon can not occur significantly to anneal, so can ensure to obtain tempering or half tempered low latitude glass.

In the time containing two or more edge band frame, described solder is in the centre of described edge band frame. Described edge band frame in the time thering is the upper surface of middle plate glass of convex surface safety glass of two low dead levels, identical with described lower-glass, in the time of the lower surface of described plate glass, identical with described upper glass.
Many one than the edge band frame of described upper glass of the edge band frame of described lower-glass, be that described upper glass at least contains an edge band frame, described lower-glass at least contains two edge band frames, the edge band frame of described upper glass is inserted in the middle of the edge band frame of described lower-glass, on described, the edge band frame of lower-glass is entrenched togather mutually, low dead level is carried out to labyrinth sealing, described edge band frame is in the time having the upper surface of middle plate glass of convex surface safety glass of two low dead levels, identical with described lower-glass, in the time of the lower surface of described plate glass, identical with described upper glass.
The introducing of edge band frame not only can limit solder and dissolve and randomly flow, make edge sealing neatly good-looking afterwards, and play good supporting role, make solder keep certain thickness, reinforced seal effect, the more important thing is that its heating-up temperature is high, have bonding more reliably with upper lower-glass, rough surface, have more firmly and be combined with solder, thereby improve air-tightness and the reliability of low latitude glass.
