<P>PROBLEM TO BE SOLVED: To provide a functional gel holding minute bubbles therein. <P>SOLUTION: A prescribed high-pressure gas is sent into a bottom portion of an airtight container 1 from a compressed gas source 2 with a valve of a pipeline 3 opened, with a valve of another pipeline 5 closed and with a valve of an exhaust pipe 6 opened, so that the gas in a gas phase region in the upper part of the airtight container 1 is discharged and the gas phase region is filled with the prescribed gas. Next, the valve of the exhaust pipe 6 is closed, so that the pressure in the gas phase region is made higher. When the pressure in the gas phase region becomes higher, the solubility of the gas also becomes higher and a large amount of the gas is dissolved in water. After this, the valve of the pipeline 5 is opened and the high-pressure water in which the prescribed gas is dissolved up to the saturation solubility under high pressure is supplied to the water packed in another container 4 in advance. As a result, the pressure of the supplied high-pressure water is released in the water in the container 4 and the dissolved gas becomes minute bubbles. Then, a gelling agent is added into the container 4 so that the water (the low-viscosity solution) including minute bubbles is made gelatification. <P>COPYRIGHT: (C)2012,JPO&INPIT |
