Embodiment 1

[0024] A method for manufacturing curved vacuum glass, the steps are:

[0025] ⑴Cut and clean the flat glass;

[0026] ⑵Put the flat glass sheet into the heating furnace for hot bending, and the hot bending is made on a mold with deflection. The time and temperature are the same as the existing single glass hot bending process. The curvature of the two sheets of vacuum glass remains basically the same;

[0027] (3) Print the adhesive on the inner surface of the hot-bent glass, and then place the support 3;

[0028] (4) Combine the glass with the support placed, and add packing sealing material 4 to the edge between the two pieces of glass for edge sealing;

[0029] ⑸Put the combined glass into the heating furnace for heating, and then vacuumize;

[0030] ⑹ After the filler sealing material on the edge of the glass is melted and sealed and the vacuum meets the requirements, seal the suction port and cool to obtain a curved vacuum glass.

[0031] Because the sealing edge of ...

Embodiment 2

[0039] Its difference with embodiment 1 is:

[0040] Two pieces of curved glass purchased with substantially the same degree of curvature are used to manufacture curved vacuum glass instead of the curved glass produced in steps (1) and (2) of the embodiment, and the others are the same as in embodiment 1.

Abstract

The invention relates to a manufacturing method of bent vacuum glass. The method comprises the steps such as that: supports are arranged for supporting the bent glass; two glass pieces are closed; a filling material is adopted as a sealing material for sealing; vacuum pumping is carried out; an air pumping port is sealed. The method provided by the invention is innovative in that: an upper glass piece and a lower glass piece are hot-bent in a heating furnace; hot-bending is carried out on a mold with a certain deflection; the bending degrees of the two glass pieces forming the bent vacuum glass are kept similar; an adhesive is uniformly printed on the opposing inner surfaces of the two bent glass pieces; the supports are then arranged; and edge sealing and vacuum pumping are carried out, such that the bent vacuum glass is manufactured. The bent vacuum glass has a simple integral structure. The manufacturing process is reasonable. With the invention, a vacancy in glass industries is filled, and supports are provided for the developments of glass industries.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to a method for manufacturing curved vacuum glass. Background technique [0002] The sound insulation, heat insulation and thermal insulation properties of vacuum glass are much better than ordinary glass or interlayer glass, and its application prospect is very broad. The existing vacuum glass is to manually bond evenly distributed and spaced solid support columns on the flat glass. The edge sealing material generally uses glass powder with a low melting point, and the flat vacuum glass is obtained after heating and vacuumizing. With the development of science and technology and the expansion of the scope of application of vacuum glass, vacuum glass with a certain deflection, that is, curved glass, is used in more and more occasions. However, no technical reports on curved vacuum glass have been found so far. Contents of the invention [0003] The object of the present invention is t...
