Description
Technical field
The present invention relates to heat insulating construction, especially relate to a kind of fine vacuum low-temperature multilayer heat insulating structure and its processing method.
Background technology
The storage tank being generally used for storing cryogenic liquid is that multilayer insulant is wrapped on container inner liner, through bonding, bundle
Prick outer gallbladder in rear enclosure to form.Multilayer insulant is typically made up of with sept radiation shield.Radiation shield can be selected for the materials such as aluminum, copper
Matter, such as aluminium foil or aluminium plating terylene film, and sept selects the low temperature such as all-glass paper, chemical fiber paper, plant fiber paper exhausted
Hot paper.
Chinese patent cn101058209 discloses a kind of low-temperature thermal insulation paper for cryogenic liquid storage-transport vessel and supporting pipeline
Vacuum multiplayer insulation, low-temperature thermal insulation paper is combined with 0.006～0.007mm aluminium foil, then by the material being combined
Material is wrapped on inner bag cylinder, through bonding, tie up fixing after be inserted in outer gallbladder, airtight after be evacuated down to 10-4pa ；Described low temperature
