- ⁇ ⁇ ⁇ Glass wool laminate is used for the core material.
- the jacket material a jacket material in which three sides of a laminate film composed of a nylon film layer, an aluminum foil layer, and a polyethylene layer are heat-sealed is used. A core material and a gas adsorption device are inserted into the jacket material, and evacuation is performed to 10 Pa in a vacuum chamber. Thereafter, the remaining one side of the jacket material is heat sealed to produce a heat insulator.
- the gas adsorption device is manufactured in a glove box filled with an inert gas, and is stored in a gas barrier laminate bag until use. Since the laminate bag is opened immediately before application to the heat insulator, the contact time with air is about 5 minutes until vacuuming is performed.
- the size of the heat insulator is assumed to be 900 mm long, 300 mm wide, and 5 mm thick.
- the thermal conductivity measurement is performed using an auto lambda manufactured by Eihiro Seiki.
- storing for 200 days at 80 ° C. is considered to correspond to about 4 years of storage at room temperature.

Even when there is an air contact before applying to the heat insulator, the alumina ceramic porous body can delay the arrival of air. For this reason, the gas adsorption device which suppressed consumption of the copper ion exchange ZSM-5 type zeolite 5 can be obtained. This is an effect of making the internal pressure of the heat insulator formed by reducing the pressure inside the jacket material to be a higher vacuum.

Even when there is air contact before applying to the heat insulator, the non-woven film made of polyethylene can delay the arrival of air. For this reason, the gas adsorption device which suppressed consumption of the copper ion exchange ZSM-5 type zeolite 5 can be obtained. This is an effect of making the internal pressure of the heat insulator formed by reducing the pressure inside the jacket material to be a higher vacuum.

For this reason, the gas adsorption device which suppressed consumption of the copper ion exchange ZSM-5 type zeolite 5 can be obtained. This is an effect of making the internal pressure of the heat insulator formed by reducing the pressure inside the jacket material to be a higher vacuum.

- a polyethylene non-woven film is installed so as to cover the opening of the container. In this way, a gas adsorption device is produced.
- the appearance is smooth and good. This is because the gas adsorbing device can be thinned because a polyethylene non-woven film is used as a material having a lower gas barrier property than the jacket material. As a result, it is possible to reduce the thickness of the heat insulator and to improve the appearance.
- the initial thermal conductivity and the thermal conductivity after the elapse of 200 days are 0.0030 W / mK and 0.0030 W / mK, respectively, which are lower than those of Comparative Example 1 and Comparative Example 2 and exhibit excellent heat insulation performance.
