Embodiment Construction

[0026] See Figure 1 ~ Figure 4 , The present invention is a new process for the production of tempered vacuum glass, which is characterized by including the following process steps:

[0027] (1) Making a fulcrum: At least one flat glass surface is made to make a fulcrum 2, and the lead-free and cadmium-free high-temperature resistant glass glaze is uniformly dispersed and printed on the upper surface of the flat glass 7 below (see figure 1 , image 3 , Figure 4 ), forming a pivot 2.

[0028] (2) Curing: Dry the plate glass 7 that makes the pivot 2 naturally or send it into a drying oven for drying, (conventional process, natural drying for more than 1 hour, drying in a 120 ℃ oven for about 15 minutes) to form Design height and area pivot point 2.

[0029] (3) Tempering: Then it is sent to a continuous tempering furnace for tempering (conventional process) to make tempered glass 7 with fulcrum 2.

[0030] (4) Compounding and sealing: Place another piece of flat glass 4 drilled with ...

Abstract

The invention discloses a production process of toughened vacuum glass. The process is characterized by comprising the following process steps of: making a supporting point, namely making the supporting point on the surface of flat plate glass by a screen printing method; curing, namely airing naturally or drying so as to form the supporting point; manufacturing toughened glass with the supporting point; compounding and sealing; and vacuumizing and sealing an exhaust hole. The process has the advantages that: vacuum glass can be toughened or semi-toughened, so that the safety performance of a product is ensured and the application range of the product is expanded; the glass supporting point is processed in a screen printing mode, so that production efficiency is improved, automatic level is raised, the process can be applied to mass production and the thickness of a vacuum layer is convenient to adjust; due to the application of lead-free glass powder, an environmentally-friendly and nontoxic product is obtained and the low energy consumption and high efficiency of production are ensured by the low melting point of the lead-free glass powder; and due to the application of an evapotranspiration getter, the service life of the product is prolonged effectively and the transparency of glass is enhanced effectively.

Description

Technical field [0001] The invention relates to a processing method of tempered vacuum glass, which mainly improves the safety performance and service life of vacuum glass so as to be more widely used in the fields of construction, household appliances, locomotives, solar energy utilization and the like. Background technique [0002] The existing production methods of vacuum glass mainly include the following: [0003] 1. Sintering method. The vacuum glass is processed by the heating and cooling method of higher melting point glass powder. The middle fulcrum of the vacuum glass is additionally arranged manually or mechanically. The individual built-in getters are non-evaporable. Its main disadvantages are low production efficiency, high energy consumption, high lead content, low safety, low product qualification rate, relatively short product life, and inconvenient large-scale application and export of products. [0004] 2. Adopt the vacuum bag method, use film to support and seal ...
