Example Embodiment

[0053] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood, however, that elements, structures and characteristics described in one embodiment may be beneficially incorporated into other embodiments without further recitation.

[0054] refer to figure 1 , the vacuum glass preparation process of the present invention includes the original sheet opening step S1, edging step S2, opening step S3, cleaning step S4, adhesive layer coating step S5, lamination step S6, sealing step S7, degassing step S8 And the exhaust pipe closing step S9.

[0055] In the original sheet opening step S1, the glass original sheet is opened into a first glass 10 and a second glass 20 according to the size requirements. The original glass sheet can be commonly used glass, such as float glass, wire glass, coated glass, colored glass and the like. The opening tool is preferably an automatic cu...

Abstract

The invention relates to a process for preparing vacuum glass, and the process comprises the following steps of: carrying out open-mediated process on raw pieces, polishing edges, opening a hole, cleaning, coating an adhesive layer, combining the pieces, sealing, degassing and closing an exhaust pipe, wherein the step of sealing is carried out in a continuous reheating furnace at the temperature of 350-500 DEG C; and the degassing step is carried out in a vacuum furnace at the temperature of 200-320 DEG C. After the process for preparing the vacuum glass, the production continuity of vacuum glass products can be guaranteed, the manufacturing time of the vacuum glass can be shortened, the production efficiency is greatly improved, the production cost is reduced, and a firm foundation is laid for mass production of the vacuum glass products.

Description

technical field [0001] The invention relates to a glass preparation process, in particular to a vacuum glass preparation process. Background technique [0002] Vacuum glass uses the principle of a vacuum flask to seal the surroundings of two pieces of flat glass, opens air holes on the glass surface for vacuuming, and then seals the air holes to form vacuum glass. At present, the method of making vacuum glass is as follows: First, place the fine supports on the glass regularly, then put another glass of similar size with an air suction port on it, apply glass solder around the glass, and place it in a high-temperature vacuum furnace. Inside, the high-temperature sealing around the glass and heating and degassing treatment are carried out. While heating, the vacuum furnace always maintains the vacuum degree that the product needs to achieve. Finally, the temperature is lowered, and the suction port on the glass surface is melted and sealed by infrared and laser heating. [0...
