The Container is mainly composed of outer shell, inner vessel, neck, multi-layer heat insulation and canister etc.
1.The outer shell and inner vessel are made of the aluminum alloy plate featuring light weight, high cryogenic strength and corrosion resistance.
2.The neck tube is made of glass fiber reinforced plastics featuring high mechanical strength and low heat conductivity.
3.The multi-layer insulation is composed of the reflecting screen of aluminum foils with high reflectivity and insulation material with low conductivity and low gas-passing speed to reduce heat radiation.
4.The jacket between the outer shell and inner vessel is high vacuum to prevent thermal convection. Moreover, an adsorbent with a high adsorbing capacity at the cryogenic temperature is used to ensure the long-term stable and reliable performance of container.
