Embodiment 1

[0046] Embodiment 1: see figure 1 , The convex vacuum glass is composed of an upper glass 1 and a lower glass 2, the peripheries of the two pieces of glass are welded together by low-temperature glass solder 4, and the middle is a vacuum layer. The production method is as follows: First, cut two pieces of flat glass of the required size according to the shape and size of the vacuum glass to be produced, drill a through hole at the corner of the upper and lower glass to form a mounting hole 3, and grind and chamfer the upper and lower glass and cleaning and drying, utilize mechanical spraying technology to prepare sealing strips 5 and 6 at the peripheral welding place of the upper and lower glass and the periphery of the installation hole 3, and prepare the support 7 on the upper and lower glass with a dispenser; The mold is placed in a hot bending furnace, heated to the softening temperature of the glass at 550-750°C, relying on the gravity of the glass itself to make the glass ...

Embodiment 2

[0047] Example 2: see figure 2 , the convex vacuum glass is composed of upper glass 1 and lower glass 2. The two pieces of glass are tempered glass or semi-tempered glass, one of which is still low-emissivity glass. The production method is as follows: First, cut the required vacuum glass according to the shape and size A piece of flat glass and a piece of low-emissivity glass, i.e. Low-E glass, remove the film at the welding part of the low-emissivity glass, drill a through hole at the corner of the upper and lower glass to form the installation hole 3, and grind the upper and lower glass, Chamfering, cleaning, and drying, and printing sealing strips on the peripheral welding of the upper and lower glasses and the periphery of the installation hole 3; secondly, put the two pieces of glass into two forming molds respectively, and the forming mold has an upper mold And the lower mold (that is, the male mold and the female mold), the glass is sandwiched between the upper mold a...

Abstract

The invention relates to metal-welded convex vacuum glass with sealing strips and a mounting hole. The glass comprises upper glass and lower glass, and is characterized in comprising mounting holes. The upper glass and the lower glass are convex glass. At least one sealing strip is provided at the periphery of the upper glass and at the periphery of the mounting hole. At least two sealing strips are provided at the periphery of the lower glass and at the periphery of the mounting hole on the lower glass. The sealing strips of the upper glass are inserted in between the sealing strips of the lower glass. The peripheries of the upper and lower glass are welded together by using a low-temperature glass solder under normal pressure in a vacuum furnace. The mounting hole is also automatically sealed by using a metal solder. The vacuum glass and the preparation method thereof have simple process. The prepared vacuum glass and tempered vacuum glass are beneficial for mounting and application. Air-tightness of the vacuum glass can be effectively ensured. Strength, thermal insulation performance and sound insulation performance of the glass can be enhanced.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a convex vacuum glass with a metal welded sealing strip and a mounting hole and a manufacturing method thereof. [0002] Background technique [0003] 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 air extraction port. The edge sealing of this vacuum glass is carried ou...
