Description

Vacuum packaging machine for preparing non-evaporable low-temperature activated getter sheet

Technical Field

The application relates to the technical field of packaging equipment, in particular to a vacuum packaging machine for preparing a non-evaporable low-temperature activated getter sheet.

Background

Non-evaporable getters are made of getter materials with very high evaporation temperatures. Such getters do not need to be evaporable, but must be activated to provide getter properties. The activation is to make the getter have strong air suction capability through proper heating treatment. During activation, the gas emitted by the getter is either pumped by a vacuum pump or is sucked away by the evaporable getter. The activated non-evaporable getter can absorb a large amount of gas at the working temperature. Non-evaporable getters getter gases within tubes in the form of surface adsorption of the gas and diffusion of the gas into the interior of the getter. Commonly used getter materials for non-evaporable getters are: titanium, zirconium, tantalum, thorium, etc., of which the getter mainly based on zirconium is most used. After the production of the getter sheet is finished, the getter sheet needs to be packaged, the common packaging bag has poor sealing performance, and the purpose of long-term storage of the getter sheet is difficult to achieve.
