The formation of the low latitude glass of described single low dead level adopts single stage method to form, and described single stage method refers to that the edge sealing of low latitude glass and high-temperature exhaust air finish simultaneously in high temperature edge sealing stove, and can carry out batch processing to low latitude glass.
Described single stage method further comprises the steps:
The solder of packing between two edge band frames with lower-glass, and described two glass consistencies from top to bottom are stacked together, leave the exhaust-duct between two glass, then send in the high temperature edge sealing stove; High temperature edge sealing stove heating made temperature rises to more than the melt temperature of solder in the stove, reach the 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; Stopped heating reduces furnace temperature to room temperature, and described solder welds together upper and lower glass is bubble-tight, thereby obtains needed convex surface tempering low latitude glass.
It is as follows that the single stage method of described two low dead level convex surface tempering low latitude glass forms step:
The solder of packing in the middle of two edge band frames with lower convex glass and middle sheet glass face of weld, and three glass consistencies from top to bottom are stacked together, leave in twos the exhaust-duct between the glass, then send in the high temperature edge sealing stove; High temperature edge sealing stove heating made temperature rises to more than the melt temperature of solder in the stove, reach the 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; Stopped heating, with stove cooling, 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 ℃, more preferably 260～320 ℃ or 320～470 ℃.
When the melt temperature of described solder is 320～470 ℃, the problem of annealing because welding temperature is too high for solving toughened glass, high temperature edge sealing stove can have basic heating system and local heating system, the basis heating system can adopt the mode of resistive heating such as nichrome wire, electrothermal tube, hot plate etc., with high temperature edge sealing furnace interior and glass heats to a basal temperature; The modes such as recycling resistive heating, infrared heating, LASER HEATING, Electromagnetic Heating, microwave heating are that local heating is carried out in the edge sealing position to the periphery of glass, reach the purpose that at short notice solder is heated to melting.
The scope of described basic Heating temperature is preferably 280～320 ℃, and the scope of edge sealing temperature is preferably 320～470 ℃.
Described high temperature edge sealing stove or the single-unit furnace of batch production, or the tunnel kiln of continous way production, preferred tunnel kiln.
Atmosphere or air in the described high temperature edge sealing stove, or the neutral atmospheres such as nitrogen, argon gas, preferred argon gas.
When the atmosphere in the high temperature edge sealing stove is neutral atmosphere, by transmission and the exchange of gas under the high temperature, can reduces moisture and oxygen content in the low dead level of low latitude glass, thereby further improve the performance of low latitude glass.
The mode of employing automatic edge sealing in high temperature edge sealing stove has been simplified technological process, has lowered production cost, has shortened the production cycle, has been improved production efficiency.
Because tempering and semi-tempered glass have higher intensity, so under identical shape and size, the convex surface of tempering or half tempered convex surface toughened glass bow is high can be less, tempering or half tempered convex surface toughened glass can be more flat.Owing to utilizing forming mould with upper and lower mould, glass clamp is relied on the moulding of exerting pressure between upper and lower mould, so convex surface toughened glass has more regular shape, and prevent 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, the temperature of glass edge is 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 guarantee to obtain tempering or half tempered low latitude glass.
In the described low dead level, when high large, the convex shape that can rely on glass self of less or convex surface bow and intensity opposing normal atmosphere, can not establish upholder when the planar dimension of upper and lower glass; When upper and lower glass can not rely on the convex shape of self and during intensity opposing normal atmosphere, the upholder of a small amount of necessity should be set, upholder is resisted normal atmosphere jointly with glass.
Described upper and lower glass is toughened glass, or semi-tempered glass, or low radiation toughened glass, or low radiation semi-tempered glass, or the combination of above any two or three kinds of glass.
The shape and size of described low latitude glass are being satisfied under the prerequisite of service requirements by the purposes decision of low latitude glass, and its shape is preferably square or circular.

The height of described edge band frame is preferably 0.1～10mm, 0.5～2mm more preferably, and width is preferably 0.2～5mm, more preferably 1～2mm.
When containing two or more edge band frame, described solder is in the centre of described edge band frame.Described edge band frame when the upper surface of the middle sheet glass of the convex surface toughened glass with two low dead levels, identical with described lower-glass, when the lower surface of described sheet glass, identical with described upper glass.
The edge band frame of described lower-glass is Duoed one than the edge band frame of described upper glass, be that described upper glass contains an edge band frame at least, described lower-glass contains two edge band frames at least, 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 labyrinth seal, described edge band frame is when the upper surface of the middle sheet glass of the convex surface toughened glass with two low dead levels, identical with described lower-glass, when the lower surface of described sheet 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 temperature is high, with upper lower-glass more reliably bonding is arranged, surface irregularity, have more firmly with solder and to be combined, thereby improve resistance to air loss and the reliability of low latitude glass.
