Abstract
It is an object of this invention to obtain a high-accuracy foamed product with high productivity. To achieve this object, a method of storing a material into which a gas saturates, before the material is foamed in a metal foam, while maintaining the gas saturated state is disclosed. This method stores a material into which a gas saturates at a predetermined ambient pressure and predetermined ambient temperature, thereby preventing escape of the gas from the material into which the gas saturates.

A method of storing a material into which a gas saturates, before the material is foamed in a metal foam, while maintaining a gas saturated state,
- wherein the material into which the gas saturates is stored at a predetermined ambient pressure and predetermined ambient temperature, thereby preventing escape of the gas from the material into which the gas saturates.
A method of storing a material into which a gas saturates, wherein a gas is allowed to saturate into a resin material at a saturation pressure P (MPa) of not less than 4 (MPa) and a temperature T (°C.), and, letting m (−0.05<m<0.2) be a coefficient determined by a material type and a gas saturation time, the material is stored in an ambient defined by a pressure p (MPa) represented by
- p=P(0.02P+m)
- and a temperature t represented by
- 0.1875T−10<t<0.5T−10
- where 20° C.≦T≦60° C.
- and represented by
- 0.1875T−10<t≦20° C.
- where T>60° C.
A method of storing a material into which a gas saturates, wherein 0.1 to 1.5 wt % of supercritical carbon dioxide are allowed to saturate into a pelletized solid resin material, and the solid resin material is stored at a temperature lower than a gas temperature when the carbon dioxide saturates, and at a high gas density.
A method of storing a material into which a gas saturates, wherein 0.1 to 1.5 wt % of supercritical carbon dioxide at a gas density of 0.08 to 0.2 g/cm2 are allowed to saturate into a pelletized solid resin material, and the solid resin material is stored at a gas density of 0.7 to 1.0 g/cm2.
