Abstract
A method for producing thermo-insulating elements wherein porous, powdery insulating material is thermally degassed and poured into an evacuated casing. Getter material is mixed with insulating material to form a mixture. The mixture is then thermally degassed. The degassed mixture is poured into an evacuated casing, which is then sealed. The getter material may comprise powdery or pellet-shaped molecular sieve, a zeolitic material, or a metal alloy. The method may be performed by degassing the mixture in a vacuum drier, and feeding the mixture in continuous vacuum into a permanently evacuated container.
Claims9
A method for producing thermo-insulating elements wherein porous, powdery insulating material is thermally degassed and poured into an evacuated casing, the method comprising:
- mixing getter material to the insulating material to form a mixture;
- thermally degassing the mixture;
- and
- introducing the pre-degassed mixture into a pre-evacuated casing, thereafter sealing said evacuated casing.
