preparation example Construction

[0038] The upper and lower glasses are prepared from flat glass, and the preparation method further includes: preparing the flat glass into a convex glass by using a mold in a bending furnace through the gravity of the glass itself or an external pressure.

[0039] The preparation method further comprises:

[0040] The first step is to cut two pieces of flat glass of the required size according to the shape and size of the convex vacuum glass to be produced, and perform edge grinding, chamfering, cleaning and drying;

[0041] In the second step, put the processed two pieces of flat glass into the forming mold, put them into the hot bending furnace, raise the temperature to the softening temperature of the glass, rely on the gravity of the glass itself or the external pressure to make the glass downward to form a convex surface, and then put it into the furnace. When the temperature is lowered to room temperature, the upper and lower glasses in the shape of convex glass are obt...

Embodiment 1

[0137] Embodiment 1: see figure 1 , the vacuum glass is composed of an upper convex glass 1 and a lower convex glass 2, both of which have edge banding strips, the periphery of the two glasses is welded together by low-temperature glass solder 3, and the middle is a vacuum layer. The production method is as follows: First, cut two pieces of flat glass of the required size according to the shape and size of the vacuum glass to be produced, then grind and chamfer the edges, after cleaning and drying, apply low-temperature glass powder paste on the two pieces of glass by printing technology. Printed edge banding frame, wherein the upper glass has one edge banding frame, the lower glass has two edge banding frames, the size of the upper glass edge banding frame is between the two edge banding frames of the lower glass, the upper and lower glass After the glass is combined, the edge sealing strip frame of the upper glass can be fitted between the two edge sealing strip frames of th...

Embodiment 2

[0140] Example 2: see figure 1 , the two pieces of glass are tempered glass or semi-tempered glass, one of which is still low-emissivity glass, and there are edge-sealed frames on the two pieces of glass. The production method is as follows: First, cut the required size according to the shape and size of the vacuum glass to be produced. A piece of flat glass and a piece of low-emissivity glass are edged, chamfered, cleaned and dried, and the low-temperature glass powder paste is printed on the two pieces of glass by screen printing technology to form an edge band frame. The upper glass has a There are two edge-seal frames and lower glass edge-seal frames, the size of the upper glass edge-seal frame is between the two edge-seal frames of the lower glass, after the upper and lower glass are combined, the edge seal frame of the upper glass can Fitted between the two edge-sealed frames of the lower glass; secondly, put the two pieces of glass into the mold, place them in a hot ben...

Abstract

The invention provides convex vacuum glass, comprising upper glass and lower glass, wherein edge banding frames are respectively arranged at the peripheries of welding surfaces of the upper glass and the lower glass, the periphery of the upper glass and the periphery of the lower glass are welded together by virtue of low temperature welding flux, the low temperature welding flux is low temperature glass welding flux, a closed vacuum layer is formed between the upper glass and the lower glass, the upper glass and the lower glass are convex glasses, and convex surfaces of the upper glass and the lower glass face the outside. The manufacturing method of the vacuum glass provided by the invention is simple in process, and the manufactured vacuum glass and tempered vacuum glass can overcome the defects in the prior art, can effectively guarantee air tightness and are enhanced in transparency, strength and heat insulation and sound insulation performances and also can lighten light pollution of a glass curtain wall.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a vacuum glass and a manufacturing method thereof. Background technique [0002] Vacuum glass is a new type of energy-saving product. It is mainly used in doors and windows of buildings, automobiles and ships, as well as in agricultural greenhouses, refrigerators, warming cabinets and refrigerators. It is an excellent thermal insulation, heat insulation and sound insulation material. Its thermal insulation, sound insulation performance, anti-frost and condensation performance, and wind pressure resistance are much better than single-layer flat glass and various insulating glass. In the existing vacuum glass, two parallel glass plates are sealed and welded to form a space in the middle, and the space is evacuated to form a vacuum layer. Since the two parallel glass plates of the vacuum glass will be pressed together under the action of atmospheric pressure, in order to e...
