Ag Zeolite Hydrogen Getter With Cryogenic Vacuum Space
Ag 400 silver molecular sieve is a new generation of high-efficiency hydrogen absorbing material used in the vacuum interlayer of high-vacuum multi-layer insulation containers. It can effectively adsorb the slowly released H2 of carbon steel, stainless steel, insulation materials, etc., so as to ensure that the interlayer always maintains super High vacuum.

IONEX TYPE AG 400 for The high-vacuum multi-layer insulation tank is mainly composed of the outer shell (carbon steel), inner tank (stainless steel), reflective material (aluminum foil), and insulation material (cellophane).
1.the adsorption capacity of PdO for H2 is about 8 times that of Ag400. In practical use, taking into account the influence of other factors, in order to ensure the same hydrogen adsorption performance, the recommended amount of Ag400 is 10-15 times that of PdO;
2.the adsorption capacity of Ag400 is higher than that of imported and domestic products;
3.Application of hydrogen getter in high-vacuum multi-layer insulation tank plays a key role in maintaining the vacuum degree for a long period. The maintenance of vacuum degree mainly depends on the characteristics and amount of the hydrogen getter, and whether it can work well.
Ag400 silver molecular sieve is a new generation of high-efficiency hydrogen absorbing material used in the vacuum interlayer of high-vacuum multi-layer insulation containers. It can effectively adsorb the slowly released H2 of carbon steel, stainless steel, insulation materials, etc., so as to ensure that the interlayer always keeps a super High vacuum. Ag400 silver molecular sieve adopts brand new small-crystal molecular sieve synthesis technology, fully crystalline molecular sieve carrier molding technology, and active silver ion loading and activation technology so that it has excellent mechanical strength, hydrogen absorption rate, and hydrogen absorption capacity at the same time.
Silver-Exchanged Zeolite Usage
Due to the different production processes and operations of each manufacturer, it is generally recommended that the dosage of Ag400 be 10-15 times that of palladium oxide, and there is no need to activate it before use;
Storage
In order to avoid damage to the glass bottle during transportation and storage, add foam packaging.
