Embodiment 1

[0043] Example 1. A vacuum glass production process, the steps of which are as follows: First, put water-soluble inorganic salt glass liquid on one of the glasses to form a glass liquid pile, and coat the glass surface with the glass liquid pile along the periphery. Apply a closed strip of water-soluble inorganic salt glass fluid, and then set several anti-adhesion supports between the upper and lower sheets of glass. After the sheets are combined, they are placed in an exhaust furnace for curing. The heap is also solidified to form a glass support. After vacuuming, cooling, and sealing, the vacuum glass is obtained after finishing; the water-soluble inorganic salt glass liquid is an inorganic compound salt soluble in water or other liquid solvents, including silicate Types, phosphates or sulfates, also including water-soluble silicate glass liquid.

Embodiment 2

[0044] Example 2. A production process of vacuum glass, the steps are as follows:

[0045] (1) Put the cleaned and surface-treated glass on the countertop, and use the computer-controlled dispensing equipment to put the water-soluble inorganic salt glass liquid on the glass at multiple points at a time, forming glass liquid piles on the glass surface ; After repeated placement, the glass liquid piles are evenly distributed on the glass surface;

[0046] (2) Apply a closed strip of water-soluble inorganic salt glass fluid along the periphery of the glass on the glass surface where the glass fluid piles are placed with computer-controlled coating equipment, and set aside;

[0047] (3) Glue several glass anti-adhesion supports on another glass surface that is drilled with vent holes;

[0048] (4) Lamination; Align the glass bonded with some glass anti-adhesion supports and put it on the glass with glass liquid piles; put the non-evaporable getter into the hole of the vent hole;...

Embodiment 3

[0051] Example 3. The production process of the vacuum glass described in embodiment 2, in step (1), the dot pitch of the molten glass heap is 10mm, the height of the glass molten heap is 0.1mm, and the bottom surface diameter of the glass molten heap is 1mm; step (2 The water-soluble inorganic salt glass liquid edge sealing width described in ) is 2mm, and the height is 0.1mm; The exhaust temperature of the exhaust furnace chamber described in the step (6) is 260 ℃, and the holding time is 5 minutes; the step ( 6) The organic or inorganic sealant described in 6) is applied to the joint between the glass and the exhaust glass pipe.

Abstract

The invention relates to a production technique of vacuum glass. The production technique is characterized by comprising the following steps: a glass liquid point of water-soluble inorganic salt is placed on one of glass so as to form glass liquid stacking matters, a closed water-soluble inorganic salt glass liquid strip is coated along the periphery of the glass surface pointed with the glass liquid stacking matters, then a plurality of adhesion protective supports are arranged between an upper piece of glass and a lower piece of glass, after closed, the two pieces of glass are arranged in an exhaust furnace for curing, the glass liquid stacking matters are also cured to form a glass support while curing and sealing the edges, the glass support is vacuumized, temperature-reduced, sealed and finished and then the vacuum glass can be obtained; the glass liquid of the water-soluble inorganic salt belongs to inorganic compound salts which are dissolved in water or other liquid solvents, comprising silicates, phosphates or sulfates, and also comprises water-soluble silicate glass liquid. The technique can improve the quality of the produced vacuum glass, improves the production efficiency, greatly reduces the production cost, does not have environmental pollution and is beneficial to the promotion and use of the vacuum glass.

Description

technical field [0001] The invention relates to an industrial production method for making vacuum glass from water-soluble sealing and supporting materials. technical background [0002] The thermal insulation of transparent materials has always been one of the hot spots that modern technology needs to solve. Because in today's life, transparent insulation materials are inseparable from many fields such as construction, home appliances, transportation and renewable energy. The most ideal solution for transparent thermal insulation materials is to use glass with a vacuum layer. [0003] The production method of vacuum glass in the prior art is: place some supports between two glass plates, and seal the surroundings of the two glass plates with sealing materials; Empty the air between the two glass plates, so that the middle cavity is in a vacuum state; then seal the vent hole, which can be made into vacuum glass. [0004] Since the disclosure of CN 94192667.2, there have b...
