Abstract: PROBLEM TO BE SOLVED: To solve a problem wherein a binder disperses over the whole glass fiber in a vacuum heat insulating material, solid heat conductivity increases in a core material where the inside of a fiber molded body is also uniformly bound, and the heat insulating performance of the vacuum heat insulating material degrades. SOLUTION: Concentration of the binder varies in the thickness direction of the core material of the vacuum heat insulating material. A part having small binder concentration is disposed, thereby reducing solid heat conductivity and improving the heat insulating performance. Further, the part having small binder concentration has a small exhaust resistance, so that degree of vacuum at an exhaust time can be easily decreased and the productivity of the vacuum heat insulating material is improved.

Abstract: PROBLEM TO BE SOLVED: To improve insulation efficiency or productivity of an insulated box body which can be used for a refrigerator, an insulation unit, a cold insulation unit, or the like. SOLUTION: A vacuum heat insulation material having a sheet core metal of an inorganic fiber assorted structure is used for an insulated box body, which is excellent to suppress deterioration with age of heat insulating efficiency and in productivity. A shape working of the core material can easily be done, the vacuum insulation material, suitable to a required heat insulation part, can easily be manufactured so as to apply to the insulated box body. Thereby the coverage of the vacuum insulation material for the insulated box body can be increased further improving the heat insulation properties of the insulated box body.

Abstract: PROBLEM TO BE SOLVED: To easily deform a vacuum heat insulating body into a form along a volume body to be insulated by providing grooves penetrating the end parts of one face or two faces of a core material, in the vacuum heat insulating body constituted of a core material made of powder material solidified into a flat plate, and an outer covering material made of plastic laminate having aluminum. SOLUTION: In a core material 1, for example, condesed silica powder and calcium silicate powder are mixed together, to form a powder compact compressively molded into a rectangular powder molding body. A plurality of grooves 2 are provided so as to penetrate the end parts of the one face of the core material 1 in parallel. Meanwhile, this vacuum heat insulating body 3 is formed so that the core material 1 is dried in a hot air drying furnace, and after inserting it into an outer covering material 4 made of an aluminum deposited laminate film of which the three sides are heat-fused, remaining one side is heat-fused and simultaneously released in the atmosphere. Stress due to atmospheric compression is concentrated to the grooves 2 of the core material 1, and the vacuum heat insulating body 3 is easily deformed in the direction of burying the spaces formed by the grooves 2. Hereby the cylindrical vacuum heat insulating body 3 can be formed simply and quickly.

Abstract: PURPOSE: To keep the performance of a vacuum heat insulator over a long period in the vacuum heat insulator formed of a facing material, a core material and an adsorbent which is usable as a heat insulating material for refrigerator by using, as the adsorbent, a one having at least a non-evaporation type getter material. CONSTITUTION: This vacuum heat insulator 1 is manufactured by filling a core material 2 consisting of a hard urethane foam of open cell structure and a getter material 3 consisting of an alloy containing barium and lithium into a facing material 4 consisting of a metal-plastic laminated film followed by sealing under reduced pressure. The surface of the getter material 3 is preferably covered with a moisture adsorbent, and a powdery one is used as the adsorbent. Since the getter material 3 is of non-evaporation type, it need not be evaporated in vacuum atmosphere, and the handling at ordinary temperature is facilitated. Thus, it can be applied to the vacuum heat insulator 1 using plastic material as the facing material, and the heat insulating performance can be kept at high level.

Abstract: PURPOSE:To provide a high orientation rate and improve insulation performance by forming hard urethane foam of continuous bubble structure via a double conveyor, removing a skin from the foam and slicing the foam in the same direction as the travel of the double conveyor for use as a core material. CONSTITUTION:A vessel 3 is filled with a hard urethane foam core material 2 having continuous bubble structure, a barrier material 5 and an adsorbing agent 6. Then, the vessel 3 is sealed with a cover material 4, thereby forming a vacuum insulation pack 1. In this case, the hard urethane foam core material 2 is made by removing the skin layer 14 of hard urethane foam 13 of continuous bubble structure manufactured with a double conveyor and slicing a product 15 so obtained in the same direction A as the travel of the double conveyor. As a result of slicing the product 15 in the same direction, an orientation rate is improved, thereby enabling heat conduction to be lowered.
