Problems solved by technology

The disadvantages of this process are: 1. The inner diameter of the sealed glass tube cannot be too large, and only a slender glass tube can be used. The mechanical strength of this slender glass tube is relatively poor, and it is generally carried out at high temperature, so the operation is difficult; 2. After sealing, a section of glass tube similar to the opening of a thermos bottle needs to be left, which affects the appearance of the vacuum glass and the overall stress, reduces the yield, and also affects the service life of the vacuum glass

Embodiment Construction

[0026] The present invention will be further described in detail below through specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0027] A manufacturing method of vacuum glass, the steps are:

[0028] (1). Processing of top glass 1:

[0029] The upper part of the glass is machined with air extraction through holes whose upper part is open, and the number is 1-20. In this embodiment, there are 4 air extraction through holes, and the set positions are evenly distributed.

[0030] (2). Placement of vacuum glass:

[0031] Place the support 4 evenly on the upper surface of the lower glass, and then place the upper glass on the lower glass 5. The edge of the upper glass should be aligned with the edge of the lower glass, or slightly smaller than the lower glass to form a margin ; In the accompanying drawings of this embodiment, a circle of inclination angle 7 is made around the peripher...

Abstract

The invention relates to a method for manufacturing vacuum glass, which comprises the following steps: (1) processing the upper part of an upper piece of glass into an opened pumping through hole; (2) putting support objects on the upper plane of a lower piece of glass and placing the upper piece of glass on the lower piece of glass; (3) sealing vacuum glass edges and glass powder at the pumping through hole; (4) putting the sealed vacuum glass into a vacuum heating chamber for vacuumization at the vacuum degree of 10-10 Pa and steady heating at 300-500 DEG C for 10-60 minutes in a curve way; and (5) obtaining finished vacuum glass after the sealed vacuum glass is taken out of the furnace when temperature in the vacuum heating chamber slowly drops below 60 DEG C. The invention effectively overcomes the defects of the prior art, simplifies the process, improves the quality of appearance, reduces the manufacture cost of the vacuum glass, is a revolutionary innovation for vacuum glass manufacturing process and greatly promotes the development of the vacuum glass industry.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to a manufacturing method of vacuum glass. Background technique [0002] Vacuum glass is a kind of thermal insulation material, which is often used in doors and windows in the construction field. Its structure is generally that two pieces of glass are placed in parallel with a support installed between them, and the edges of the two pieces of glass are sealed with low-melting glass powder. The internal space formed by the vacuum glass requires a certain degree of vacuum (the negative pressure is about 10 -2 Pa), in order to achieve excellent and stable thermal insulation performance, a vacuuming step is required in the vacuum glass manufacturing process technology. At present, the vacuum treatment of vacuum glass basically follows the traditional process, that is, the vacuum is realized by connecting the exhaust pipe connecting the inner space of the vacuum glass to the vacuum system. ...
