Abstract:
Refrigerators containing vacuum insulation material which has glass fiber assembly as the core material and rigid urethane foam are pulverized separately from refrigerators not containing vacuum insulation material, and the waste thermal insulation materials discharged from these types of refrigerators are stored in different recovery towers for waste thermal insulation materials. In an inorganic material content adjusting process, appropriate amounts are fed from the respective recovery towers into a mixer so as to prepare mixed waste materials whose inorganic material content has been adjusted. In the subsequent waste material processing process, the mixed waste materials with an adjusted percentage of inorganic material content are subjected to an appropriate powdering operation, and the resulting powder is sealed into a packaging member under a reduced pressure so as to obtain vacuum insulation material.

Vacuum heat insulator comprising a laminated core made of a plurality of sheets of inorganic fibers having 10 mu m or smaller in diameter and a certain composition including SiO2 as a main component, Al2O3, CaO, and MgO, a gas barrier enveloping member, and an absorbent. The vacuum heat insulator is characterized by having at least one groove formed therein after fabrication of the vacuum heat insulator. Further, the vacuum heat insulator is characterized by using inorganic fiber core of which a peak of distribution in fiber diameter lies between 1 mu m or smaller and 0.1 mu m or larger, and not containing binding material for binding the fiber material. Electronic apparatuses of the present invention use the vacuum heat insulator. With use of the vacuum heat insulator, electronic and electric apparatuses superior in energy saving and not to present uncomfortable feeling to the user can be provided.

Abstract:
A method for recycling thermal insulating materials including a vacuum thermal insulating material and a hard urethane foam, which comprises a step of separately crushing a refrigerator equipped with a vacuum thermal insulating material using a glass fiber assembly as a core material and a hard urethane foam and a refrigerator having no vacuum thermal insulating material, a step of storing the resulting respective waste insulating materials in different waste insulating material recovering towers, an inorganic material content adjustment step of supplying respective appropriate amounts of respective waste insulating materials to a mixer from respective recovering towers, to prepare a mixed waste material having an inorganic material content suitably adjusted, and a waste material processing step of subjecting the mixed waste material to a suitable pulverization treatment and sealing the resultant material with a covering material under a reduced pressure, to thereby produce a vacuum thermal insulating material; a recycled article produced by the method; and a refrigerator which allows the application of the method. The method can be employed for maintaining the quality of a mixed waste material at a constant level and thus reusing it as a high quality material.
