Conventionally, insulated tanks for keeping heat and cold have been used by filling the space between the double walls of the tank body with a double wall structure, and filling the space between the double walls with inorganic porous powder such as diatomaceous earth or perlite. It is known that the space is sealed and evacuated.

In this type of insulated tank, the radiation heat transfer in vacuum is suppressed by the powder filled in the space between the double walls, and the insulation is achieved very well. In addition, if the filling density is uneven, heat radiation will be concentrated in areas with low density, so there is a drawback that the heat retention of the tank as a whole will be significantly reduced.

For example, in conventional cold storage tanks for liquefied gas, pearlite powder is generally used as the powder, and its packing density is 0.1 liters/cyn5 to o, 2 liters/cm'. However, according to experiments conducted by the present inventors, the above packing density is still not sufficient, and is 0.65 to 0.9097c.
When the temperature is increased to m', radiant heat transfer almost disappears,
It was found that the insulation effect was dramatically improved.

However, in the past, there was no method suitable for industrial mass production to fill the space between the double walls of the double wall tank with powder at the high density described above, even if it was a laboratory method. Even if it is clear that increasing the packing density is sufficient, there is a problem in that it is difficult to achieve this goal.
