Example Embodiment

[0042] Example 1:

[0043] Such as figure 2 As shown, a tempered vacuum glass includes an upper glass 1, a lower glass 2 and a support 6 arranged between the two. The support 6 is a mesh support (such as image 3 ), the size of the mesh support is smaller than the size of the upper and lower glass 3cm, the upper and lower glass are sealed with PVB material 3, and an exhaust groove 5 is set on one side to hollow the two pieces of glass to form a vacuum cavity, The outer side of the PVB material 3 is further sealed with tin 4, the width of the tin is preferably 0.3 cm, and the width of the PVB material is preferably 2 cm.

[0044] The production method of the above-mentioned tempered vacuum glass is:

[0045] 1) Cut two pieces of glass of the required size according to the shape and size of the tempered vacuum glass to be produced, and perform edge grinding, chamfering, cleaning and drying treatments;

[0046] 2) Place a net-like support between the upper and lower glass, and leave a s...

[0058] Example 3

[0059] A tempered vacuum glass, including upper, middle, and lower glasses and dot-shaped raised substances arranged in an array between two glasses (such as Figure 4 ). Its overall size is less than the size of the upper and lower glass 2cm. The corresponding side of the upper, middle and lower glass is sealed with PVB material, and an exhaust groove is set on this side. The width of the PVB material is 2cm, and the other sides Use low-temperature solder to print the frame.

[0060] The production method of the above-mentioned tempered vacuum glass is:

[0061] 1) Cut two pieces of glass of the required size according to the shape and size of the tempered vacuum glass to be produced, and perform edge grinding, chamfering, cleaning and drying treatments;

[0062] 2) Print dot-shaped bumps arranged in an array in the middle of the upper, middle and lower glass, leaving a space of 2cm around the glass;

[0063] 3) For the upper, middle and lower glass, one side is co...

Abstract

The invention relates to tempered vacuum glass and a production method thereof, wherein the tempered vacuum glass includes upper glass, lower glass and a support object therebetween. The support object is smaller than the upper glass and the lower glass. The upper glass and the lower glass are sealed with an edge sealing material to form a vacuum chamber between the upper glass and the lower glass, wherein at least one edge of the edge sealing material is prepared from PVB. The tempered vacuum glass has following advantages: (1) the tempered vacuum glass is simple in structure, is simplified in process, is low in production cost, is improved in vacuumizing efficiency, and is easy to achieve a high vacuum degree in the vacuum chamber; (2) the support object is easy to arranged and is not liable to fall-off, so that the glass is free from cracking at supporting positions; (3) the tempered vacuum glass is improved in edge sealing quality since the PVB is used as the edge sealing material and a secondary edge sealing material and a secondary edge sealing process are employed on the basis of the PVB, so that the vacuum degree of the vacuum chamber can be maintained durably; (4) the tempered vacuum glass is lower than 200 DEG C in vacuumizing temperature, so that problems of reduction of residual stress and reduction of strength of the tempered vacuum glass due to glass annealing can be avoided, thereby improving quality, service life and safe performance of the tempered vacuum glass.

Description

technical field [0001] The invention relates to the technical field of vacuum glass processing, in particular to a tempered vacuum glass and a production method thereof. Background technique [0002] Existing vacuum glass is generally composed of two pieces of flat glass and a vacuum layer in the middle. Since there is no heat and sound transmission of gas, and the inner surface of the glass can have a transparent low-heat radiation film, the vacuum glass has good insulation properties. Heat and sound insulation effect, is the best performing energy-saving glass. [0003] The existing vacuum glass has the following disadvantages: [0004] (1) The structure is complex and the process is cumbersome: glass drilling, production and welding of suction glass tubes, placement of supports and getters, coating of low-temperature glass solder on the periphery, sealing of the periphery by heating, heating, vacuuming and exhausting and sealing and pumping Air port, air extraction port...
