Method for making low-temperature adhesive plate vacuum glass and apparatus thereof

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: [0001] The invention relates to a method and equipment for making flat vacuum glass with a smooth outer surface, no vertebral tail, and no sealing plug. Background technique: [0002] It has been scientifically proven that the sound insulation and thermal insulation performance of flat vacuum glass is much higher than that of insulating glass, and it is the most ideal building energy-saving and environmental protection glass. The insulation volume of insulating glass is 24-27 decibels, the insulation volume of vacuum glass is 31-45 decibels; the heat transfer coefficient of insulating glass is 1.8-3.4WM-2K-1, and the heat transfer coefficient of vacuum glass is 0.7-0.9WM-2K -1 Energy saving is 35%--40% compared with insulating glass, and 55%--60% compared with single-layer glass, and the effect of sound insulation and energy saving is very significant; Promotional use. [0003] In the field of low-temperature bonded vacuum glass production, existing data r...

Problems solved by technology

The vacuum glass produced in this way leaves a rubber seal (or other materials) on the surface, which is not beautiful in appearance, and the deep processing of the product is difficult. clean, the vacuum degree is not guaranteed; the glass needs to be drilled, and the rubber stopper needs to be produced separately. There are many production links and the product cost is high.
