Problems solved by technology

Generally, two pieces of glass are used in the manufacturing process, and a support is sandwiched between them. There is a metal air suction port on one of the glass, and vacuum equipment is used to evacuate from this port, and the vacuum glass needs to be well sealed in each step of the production process. At present, when producing vacuum glass, the pads placed on the general craft market are made of small black dots between two pieces of glass, and then vacuumized, but the black dots affect the appearance, etc.

Abstract

The invention discloses a vacuum glass production process. The vacuum glass production process comprises the following steps: (1) cutting glass; (2) edge grinding and cleaning are conducted; (3) aluminum alloy supporting strips are arranged; (4) coating a circle of closed low-melting-point glass powder; (5) micro-beads are arranged; step (6), laminating; (7) heating the laminated glass in the kettle at high pressure and high temperature, and vertically placing or flatly placing the glass on a bracket; (8) heating the high-pressure and high-temperature heating kettle to a glass powder melting point under normal pressure, and then pressurizing, preserving heat and pressure, reducing pressure, cooling and sealing edges; (9) vacuumizing and hot melting sealing are carried out; and (10) obtaining the vacuum glass. According to the invention, the cleanliness and integrity of the produced vacuum glass are ensured by using the dual design of the aluminum alloy supporting strips and the microbeads, and the aesthetic degree of the vacuum glass is also improved to a certain extent.

Description

technical field [0001] The invention relates to a vacuum glass production process, which belongs to the technical field of building door and window glass production. Background technique [0002] With the increasingly serious global energy and environmental problems, low-carbon environmental protection has gradually become the choice of countries all over the world, and it is also the future development direction of building energy conservation in my country. Doors and windows are the core of building energy consumption, and the application of energy-saving glass has become the key to reducing building energy consumption. There are many kinds of energy-saving glass, which can be roughly divided into insulating glass, coated glass and vacuum glass. Vacuum glass is a new type of glass deep-processing product, which is developed based on the principle of vacuum flask. The structure of vacuum glass is similar to insulating glass, the difference is that the gas in the cavity of ...
