Embodiment Construction

[0011] figure 1 (a) and (b) are schematic diagrams of the structure of the glass-encapsulated getter. Put the stainless steel sheet or ring 4 and the getter block 3 assembly in the glass thin tube 1, seal it tightly in a vacuum state, seal the exhaust pipe 2, or directly put the getter block 3 into the glass tube 1, Carry out vacuum treatment and seal after filling with inert gas. of the present invention figure 2 Shown is a schematic diagram of the structure of the getter encapsulated by the metal material. Place the getter block 3 in the groove of the dish-shaped bowl 6 of the encapsulation container, cover the sealing sheet 5, fix the periphery by spot welding first, put it into the vacuum equipment for vacuum treatment, or fill it with inert gas to carry out Perimeter seal welded. The encapsulation process of the above two types of encapsulated getters is as follows: 1. Getters of corresponding sizes applied to different vacuum devices are prepared. 2. Select the enc...

Abstract

The present invention discloses an encapsulated getter belongs to the field of vacuum getter techonlogy, and is characterized by that metal sheet or ring and getter component are placed in glass thin-wall pipe and tightly encapsulated or the getter is placed in metal thin-wall container or glass thin-wall container, said container is evacuated or charged by inert gas, then sealed and stored. Said invention is applicable to various vacuum devices, said getter can be stored for a long period, and can provide convenience for next procedure.

Description

technical field [0001] The invention belongs to the technical scope of vacuum getters, and in particular relates to an encapsulated getter which can not be oxidized in a high-temperature atmospheric environment. Background technique [0002] Any vacuum device, especially high vacuum device, due to chronic air leakage or outgassing of materials, will cause the vacuum degree in the device to drop, and the performance of the device will deteriorate until the end of life. In order to prolong the lifetime, in addition to strict handling specifications during the vacuum processing process, it is necessary to place a getter inside the device. The getter is composed of active materials, and it is easy to oxidize and fail when exposed to the atmosphere for a long time, especially when exposed to a relatively high temperature atmosphere, the oxidation is very rapid. However, in the manufacturing process of some vacuum devices, some processes must be subjected to high-temperature trea...
