Abstract: PROBLEM TO BE SOLVED: To improve the recycle property of a vacuum heat insulator, and reduce the weight thereof by filling the powder carrying at least the oxidation inhibitor in a part of the powder formed by crashing the organic resin composition as a core material of a vacuum heat insulator in an inner bag material having a ventilating property. SOLUTION: The powder 4 of the crashed organic resin composition powder and the oxidation inhibitor 5 are mixed and agitated so as to manufacturing the powder 4 carrying the oxidation inhibitor 5. The predetermined a quantity of this powder 4 is filled in an inner bag material 3 having a ventilating property so as to manufacture a core material 2 for vacuum heat insulator 1. After performing the heating to the core material 2, the core material 2 is inserted with the gas adsorbent 6 into an outer material 7 made of the gas barrier type laminated film. Thereafter, evacuation is performed in a vacuum chamber provided with a thermal fusion device, and an end of the outer material 7 is sealed by thermal fusion so as to form a vacuum heat insulator 1. As an organic resin composition, the hard urethane foam as a foaming body of the urethane resin composition is especially desirable.

Abstract: PROBLEM TO BE SOLVED: To improve secular heat insulating performance by depressurizing and sealing the inside of an outer member including a room temperature activation type getter material and the like. SOLUTION: As a room temperature activation type getter material to absorb and eliminate at least nitrogen, oxygen, a water content and carbon dioxide, a combo getter including barium-lithium alloy is used for a gas absorbent 5. A predetermined amount of 'Toku-seal P(R)' 4 is filled into an inner bag member 3 having permeability so as to prepare the core 2 of this vacuum heat insulating body 1. In this case, after heat treatment is executed to the core 2 at about 150 deg.C for about 1 hour, the core 2 is inserted together with the gas absorbent 5 in a gas barrier film-made outer member 6. Vacuum exhaustion is performed by a vacuum chamber equipped with a thermal seal device, and the end part of the outer member 6 is sealed by thermal seal. At this time, exhaustion and depressurization are so performed that the initial internal pressure of the vacuum heat insulating body 1 is set to less than about 13 pascals.

Abstract: PROBLEM TO BE SOLVED: To provide a recycled material for a vacuum heat insulating body by collecting hard urethane foam waste from a selection device outlet, finely crushing the waste, and filling a ventilating inner bag material with it. SOLUTION: After waste is put in a crushing device so as to be roughly crushed, the crushed hard urethane foam waste is collected by means of a selection device. The collected waste is finely crushed by a friction type crusher so as to be turned into powder constituting a core material for a vacuum heat insulating body. Then, synthetic silica is mixed with the powder, and the mixture is stirred and charged in a ventilating inner bag material, and consequently, a core material for the vacuum heat insulating body is formed. The core material is dried at 120-180 deg.C, and then, inserted into a covering material formed of a gas-barrier film and shaped into a bag by heat sealing three sides of the gas-barrier film, and after the inside of the covering material is evacuated, the rest one side is sealed by heat sealing, and consequently, the vacuum heat insulating body is formed. In this way, hard urethane foam waste collected from the selection device outlet is finely crushed so as to be recycled as the core material for the vacuum heat insulating body.

SOLUTION: A tank 1 is arranged in a refrigerating chamber 8 while an ice making pan 6 is arranged in a freezing chamber 9 and water is supplied from the tank 1 to the ice making pan 6 through a water supply hose 2. The water supply hose 2 is coated with an anti-freeze heater 4 on the freezing chamber 9 side and both the anti-freeze heater 4 and the water supply hose 2 are coated with a vacuum heat insulating material 10. The vacuum heat insulating material 10 is made by inserting an inner bag material 12 filled with a ventilating core material 11 into an exterior material 14 made of a gas barrier film and then sealing the inside of the exterior material 14 by reducing the pressure. According to the structure, power consumption of the anti-freeze heater 4, and the like, can be reduced.

Abstract: PROBLEM TO BE SOLVED: To lighten a vacuum heat insulating body by depressurizing and sealing the inside of an outer member including a room temperature activation type getter material and the like. SOLUTION: As a room temperature activation type getter material to eliminate at least nitrogen, oxygen, a water content and carbon dioxide, a combo getter including barium-lithium alloy is used for a gas absorbent 6. Powder 4 formed of hard urethane foam powder prepared by being ground and 'a Toku-seal P(R)' 5 equivalent to about 3 wt.% in 2 weight parts of a core 2 are mixed with each other and agitated, and a predetermined amount is filled into an inner bag member 3 having permeability, thereby the core 2 of this vacuum heat insulating body 1 can be prepared. At its time, the 'Toku-seal P(R)' 5 is reacted as a supreplasticizer, therefore the powder 4 formed of the hard urethane foam powder can be formed into the best filling shape. After heat treatment is applied to the core 2 at about 150 deg.C for about 1 hour, the core 2 is inserted together with the gas absorbent 6 in a gas barrier film-made outer member 7. Vacuum exhaustion is performed by a vacuum chamber equipped with a thermal seal device, and the end part of the outer member 7 is sealed by thermal seal.

Abstract: PROBLEM TO BE SOLVED: To provide an excellent heat insulating body with a high degree of shape freedom by means of simple manufacturing equipment by covering a core material made of powder with a gas-barrier film and specifying an internal pressure to a specific value. SOLUTION: An organic resin composition or an inorganic composition is used for powder 2 constituting a core material 4 for a decompressed heat insulating body 1, and a gas-barrier film 5 container is filled with the powder 2, while the container is sealed after its internal pressure is reduced to 1-90 kPa. Therefore, the shape of the heat insulating body 1 can be maintained by an atmospheric pressure only because it is filled with the powder 2, so that neither use of a binder nor heat press molding is required. If the inner pressure of the heat insulating body 1 exceeds 90 kPa, the thickness of the heat insulating body 1 is increased/reduced, and its shape is hardly maintained, so that of the powder 2 distribution inside the heat insulating body 1 is deflected. On the other hand, for reducing the inner pressure below 1 kPa, a dedicated large-scale exhaust device is required and complication of the process management in a previous processing process such as drying power and in an exhaust process occurs.

Abstract: PROBLEM TO BE SOLVED: To improve heat insulating performance without increase in solid heat conductivity by mixing powder with a grain size within one specific range and powder with a grain size within another specific range together for using the mixture as a core material for a vacuum heat insulating material. SOLUTION: A vacuum heat insulating material 1 consists of a core material using powder with grain sizes showing volume frequency peaks at 100-400 μm and at 1-50 μm in a histogram representing a volume frequency to a grain size and a coating material covering the core material. Because these kinds of powder 4 is applied to the core material for the vacuum heat insulating material 1, a void in the powder is reduced and gas heat conductivity is reduced, while increase in conduction points between the powder is lowered and solid heat conductivity is not also increased, and consequently a heat insulating material with excellent heat insulating performance can be provided. As the grain sizes of the powder 4 are limited within a range of 100-400 μm and within a range of 1-50 μm, the vacuum heat insulating material 1 excellent in both of gas heat conductivity and solid heat conductivity can be provided.
