Background

The vacuum glass sample wafer which is baked at high temperature and exhausted is subjected to long-time solarization test, and the thermal conductivity of part of the vacuum glass is found to be increased to a certain extent after measurement. This means that the life of the vacuum glass cannot be fully guaranteed by baking and exhausting at a high temperature, and a getter must be placed in the vacuum glass to improve and maintain the vacuum performance of the vacuum glass, thereby prolonging the life of the vacuum glass.

Getters are generally used in the field of vacuum technology to refer to a gas-absorbing material, and are a general term for a preparation or device for obtaining, maintaining, purifying, etc. gas molecules, and effectively absorbing certain gas (es). The main functions are as follows: the degree of vacuum of the vacuum space is increased for a short time and the desired vacuum is maintained for a long time.

In order to prevent the getter from being oxidized when the edge is sealed, the getter is required to be activated and encapsulated under a vacuum state, and the material of an encapsulating box is special metal sheet or glass. The getter used in the vertical vacuum glass production line is of an evaporable type, the solid powdered getter is made into a certain shape, such as a round cake shape, and the round powdered getter is embedded into a round metal groove for packaging after being formed, and is similar to a coin. The "encapsulated" getter does not oxidize and fail when the evacuated glass is "edge sealed" in the atmosphere. The sealed getter is put into the vacuum glass interlayer, after the vacuum pumping and the edge sealing are carried out, the sealing box is opened through unsealing to enable the getter to work, and the process is called as activation. The getter is activated by heating the edge-sealed glass at a temperature greater than 450 ℃ (adjusted according to the type of getter), and heating the glass requires energy, and also reduces the strength of the tempered glass for a longer time.
