Vacuum diffusion welding equipment for borosilicate glass with high light transmittance and use method of vacuum diffusion welding equipment

Abstract

The invention discloses vacuum diffusion welding equipment for high-light-transmittance borosilicate glass and a using method of the vacuum diffusion welding equipment. The vacuum diffusion welding equipment comprises a supporting bottom plate, a cleaning tank, a heating box and a cooling tank, and the top of the supporting bottom plate is provided with the cleaning tank, the heating box and the cooling tank. By adopting the welded glass structural part, the formed glass is a unified whole, cannot be split, is high in structural strength and sealing performance, plays a role in protecting the product structural design, has the same light transmittance as the glass before welding, can be used for special applications such as photocatalytic reaction, does not add materials such as welding flux and brazing filler metal in the forming process, and is low in production cost. Stainless steel is selected as a solder resist material, the surface and light transmission performance of the glass are not affected, a heating-pressurizing heat preservation-heating-pressure relief heat preservation-cooling process curve is adopted in the method, the main significance is to eliminate a glass welding seam interface, meanwhile, plastic deformation of the glass structure is reduced, and the heat preservation performance of the glass is improved. The light transmittance of the glass is improved.

Description

technical field [0001] The invention relates to the technical field of vacuum diffusion welding, in particular to vacuum diffusion welding equipment for high light-transmitting borosilicate glass and a method for using the same. Background technique [0002] Borosilicate glass is obtained by replacing part of the alkali metal oxides in ordinary glass with boron oxide, that is, high-boron and low-silicon borosilicate glass without alkali metal oxides, and a continuous flow microchannel with high light transmittance The reactor is made by splicing two or more pieces of glass with a reaction flow channel structure. The traditional method uses mechanical riveting and edge sealing, or bonding or brazing to realize the connection of the glass. Some of these methods need to add Solder, with low temperature and weak pressure-bearing capacity of the connection interface, will affect the light transmittance of the glass, negatively affect the application of photocatalytic reactions, o...

Problems solved by technology

Beneficial effects: the automatic hot air welding line not only reduces the labor intensity of the operator, but also has accurate welding, high efficiency, improves the accuracy and uniformity of welding, and avoids the contamination of the vacuum glass plate caused by too many manual operations", However, after the above-mentioned device is heated, it does not have a good accelerated cooling structure, which affects the work efficiency of the staff.
