Abstract: PURPOSE:To eliminate the problem of public pollution by fluorocarbon, which destroys ozone, and prevent the deformation of the appearance of an adiabatic wall due to the contraction of foams in low atmospheric temperature by a method wherein the specified range of non-amino series active hydrogen compound is added and blended as the constituent of hydroxide group while 1,1- dichloro-1-fluoroethane or 1,1-dichloro-2,2,2-trifluoroethane is employed as foaming agent. CONSTITUTION:An adiabatic wall 1 is constituted of an inner box 2, consisting of ABS resin, an outer box 3, consisting of an iron plate, and hard urethane foam 4, foamed integrally between the inner box 2 and the outer box 3. The hard urethane foam 4 is constituted of hydroxide group blended with 5-30% of non-amine series active hydrogen compound, catalyst, foam stabilizer, organic polyisocyanate and the foaming agent of 1,1-dichloro-1-fluoroethane or 1,1- dichloro-2,2,2-trifluoroethane while the adiabatic wall, formed integrally with the surface member such as the inner plate of synthetic resin and the like, can be formed.

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a hydrophobic dry-gel without using a solvent displacement process which is needed when a treatment for obtaining a hydrophobicity is applied by using a silylling agent, etc., and a solvent which does not react with the sililling agent when drying a silica wet-gel having water without shrinkage. SOLUTION: A low density dry-gel can be efficiently obtained by applying the treatment for obtaining the hydrophobicity to a wet-gel having water in a solution obtained by mixing a water soluble solvent, a water insoluble solvent and a sililling agent, and by omitting or simplifying the solvent displacement process, and further by drying the hydrophobic gel at a condition under the critical point.

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.
