Problems solved by technology

Due to the small space in the vacuum layer of vacuum glass and the transparency of the glass, the protection and activation of the getter needs to be considered, so it is very difficult to place the getter in the vacuum layer
The traditional method of placing the getter in the vacuum glass is to first package the getter under vacuum, and then place it in the groove pre-opened on the glass. Af

Embodiment 1

[0073] Embodiment 1: see figure 1The tempered vacuum glass consists of upper glass 1 and lower glass 2. The two pieces of glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass. A piece of flat glass and a piece of low-emissivity glass of the same size, the low-emissivity glass is selected as the lower glass 2, a tapered through hole is drilled at the corner of the upper glass 1 as the air inlet 3, and a sealing groove 6 is opened on the periphery of the lower glass 2, and Carry out edging, chamfering, cleaning, and drying, and use the screen printing technology to print the sealing strip with tempered glass ink on the peripheral welding of the upper glass 1 and print the support 8 at the same time; secondly, send the two pieces of glass into the tempering furnace Air-cooled tempering is carried out under the same conditions to obtain tempered or semi-tempered glass; at the same time, high polymer 12 is prepared, and high polymer 12 is polyimide....

Embodiment 2

[0074] Example 2: see figure 2 The double-vacuum-layer tempered vacuum glass consists of upper glass 1, middle glass 9 and lower glass 2. Among the three pieces of glass, at least the upper and lower glasses are tempered glass or semi-tempered glass, and the lower glass 2 or \and the middle glass 9 are still low. Radiation glass, its production method is as follows: First, according to the shape and size of the vacuum glass to be produced, cut three pieces of flat glass of the required size, and drill a tapered through hole on the upper glass 1 and the middle glass 9 respectively to form the air inlet 3 , wherein the through hole on the upper glass 1 is larger than the through hole on the middle glass 9, and the metal round tubes with lower end flanges are prepared and inserted into the air outlet, and the outer sides of the lower part of the round tube are closely matched with the lower ends of the air outlet 3 respectively, and the circle The upper part of the pipe and the ...

Abstract

A microwave-welded flat tempered vacuum glass edge-sealed with sealing grooves and having a getter is characterized in that an upper glass and a lower glass are flat tempered glasses. A vacuumizing hole is arranged in the upper glass and a sealing cover is arranged on the vacuumizing hole. The getter is arranged in the vacuumizing hole. The upper glass is provided with a sealing bar and the lower glass is provided with the sealing groove. The upper glass and the lower glass are welded to each other in a microwave oven at a normal pressure through a low-temperature glass solder. The vacuumizing hole is automatically sealed in a vacuum oven through the seal cover and a metal solder. The getter is automatically activated during the sealing process. A vacuum layer, with a supporting object therein, is formed between the upper glass and the lower glass. The edge-sealing bar and the supporting object are composed of tempered glass printing ink and a high polymer. The high polymer is firstly prepared into a pre-polymer. The pre-polymer, after the glass being tempered, is manufactured on the glass or the tempered glass printing ink. The pre-polymer is solidified to form an elastomer at room temperature or a high temperature. The pre-polymer or the elastomer can automatically adapt with change of height of the vacuum layer. Volatile gas in the elastomer is exhausted from the elastomer at a high temperature and a high vacuum degree.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat tempered vacuum glass with a getter on the edge of a microwave welding sealing groove and a manufacturing method thereof. Background technique [0002] Vacuum glass is a new type of energy-saving glass. Vacuum glass can not only solve the "breathing" problem of insulating glass used in large quantities, but also has good heat and sound insulation performance, high wind pressure resistance, small thickness and long service life. advantage. Vacuum glass is generally composed of two to three pieces of glass, a cavity is formed between two adjacent pieces of glass, and an edge sealing structure is arranged around the glass, and the cavity is evacuated to form a vacuum layer. Vacuum glass can be divided into two types according to the way of forming the vacuum layer. One is the vacuum glass without exhaust port. The edge sealing of this vacuum glass is carried ou...
