Embodiment Construction

[0023] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0024] A method for manufacturing stress uniform vacuum glass, the steps of the preparation method are:

[0025] (1). Set bonding points on the substrate glass:

[0026] Put a piece of glass as the substrate glass on the workbench, and set the bonding points uniformly on the plane. The bonding points can be arranged by a bushing mold or a silk screen. The spacing of the bonding points is 15-50mm. The diameter is 0.2-2mm, the height is 0.05-1mm, and it is in the form of dots or other shapes. The adhesive used for this bonding point is a glass adhesive commonly used in this industry.

[0027] (2). Bonding low melting point glass powder and solid support:

[0028] Stick low-melting point glass powder on the bonding point set on the substrate ...

Abstract

The invention relates to a fabricating method of vacuum glass with uniform stress, which comprises the following steps: firstly, arranging bonding points on substrate glass; secondly, bonding low melting glass powder and solid support; thirdly, combining sheet and arranging a seal edge; fourthly, heating the sheet in a heating furnace; and fifthly, vacuumizing and sealing so that the vacuum glass can be obtained. The invention has simple process, convenient operation, low cost, high yield and high production efficiency, reduces the breakage rate to be less than 10 percent and is easy to realize the industrial massive production. The fabricated vacuum glass has uniform and consistent stress, good quality, high strength and long service life, is the creative development on the fabricating process of the vacuum glass, and has great promotion function on the development of the vacuum glass industry.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to a method for manufacturing vacuum glass with uniform stress. 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. There are following shortcoming in the manufacturing method of existing vacuum glass: 1. adopt artificially to bond uniformly distributed, spaced solid support column on flat glass, this solid support adopts metal nail, ball and glass nail, ball etc., and its stability is difficult Guaranteed, the bonding efficiency is low, time-consuming, and labor costs are too high; 2. Because the flatness of the two pieces of glass is difficult to keep consistent, the support effect of the solid support is poor, and the support stress of the glass is uneven, especially in vacuum glass. After vacuuming, local stress will b...
