Abstract
The invention relates to a method for producing vacuum slab glass that has a smooth surface and has no vertebrate tail and sealing plug and an equipment thereof. One piece of glass is cut into two pieces, then a support is arranged between the two pieces of glass, a bonding agent is coated on the four sides of the glass and one notch is left without coating the bonding agent and is used as vacuum passage of later step, the two pieces of glass are placed into a vacuum box after the bonding process is finished; the inside of the vacuum box is provided with a heating device and a glue-filling machine; also a vacuum pipe is arranged on the vacuum box, then the heating device is started to heat the glass, and a vacuum valve is started to vacuumize, then the glue-filling machine is started to seal the passage, finally the vacuum box is cooled and the pressure is relived to obttain the finished vacuum glass. Compared with the other vacuum glass which has vertebrate tail protuberance on the surface and is sealed by rubber plugs, the vacuum glass production process reduces the production procedure; also the product is more beautiful as the product has no projection or sealing rubber plug; the production line is short, which needs less investment, consumes less energy and reduces the manufacturing cost.
Description
Technical field:
The present invention relates to a kind of outside surface is the making method and the equipment thereof of slick, no vertebra tail, no sealing plug planar vacuum glass.
Background technology:
Sound insulation, the heat-insulating property of science proof planar vacuum glass are higher than double glazing far away, are optimal building energy conservation environmental protection glass.The sound-damping qualities of double glazing is the 24-27 decibel, and the sound-damping qualities of vacuum glass is the 31-45 decibel; The heat transfer coefficient 1.8-3.4WM-2K-1 of double glazing, the heat transfer coefficient of vacuum glass be 0.7-0.9WM-2K-1 than the energy-conservation 35%--40% of double glazing, than the energy-conservation 55%--60% of single-glass, sound insulation, energy-saving effect highly significant; Yet because the vacuum glass manufacturing process is very complicated, cost is higher, and very difficult big area is promoted the use of.
At low temperature adhesion vacuum glass production field, existing data report low temperature adhesion planar vacuum glass is to stop up aspirating hole with rubber plug, and its manufacturing process is: 1 glass cutting--2 make a call to a taper aspirating hole for wherein a glass--3 make sealing aspirating hole rubber plugs--4 arrange upholder and seal gum all around at a slice glass in addition--5 two blocks of glass close sheet--6 close sheet after the glass silica gel bag of packing into----it is 10 procedures such as finished product vacuum glass that 10 pressure releases that 8 vacuumize--9 install sealing rubber plug--are taken out to 7 prepackage rubber plugs.The vacuum glass of Zhi Zuoing stays next rubber to seal (or other materials) on the surface like this, and appearance is not attractive in appearance, product deep layer processing difficulties, and this seals aging easily the gas leak; Can not fully heat to glass when producing in the silica gel bag, gas is difficult to emptying, and vacuum tightness does not guarantee; Need produce rubber plug in addition to glass drilling, needs, production link is many, the product cost height.
