摘要:
A method of disassembling a waste refrigerator having foam resin used as insulator, comprising the steps of cutting off the insulated cabinet body of the refrigerator into pieces of specified size and shape, pressingly passing the pieces between a pair of compression rolls disposed opposite to each other to peel off and separate incompressible platy matters accumulated on at least one surface of the pieces so as to provide the foam resin, and pressingly passing the foam resin (301) between the pair of compression rolls (331, 332) disposed opposite to each other to leak out and collect the foam gas contained in the foam resin, whereby the foam gas in the insulator can be collected in the state of high density by using a small-sized equipment at a low cost.

A method for producing a part by molding with an embedded 2D barcode defined in the surface of the part and the embedded 2D barcode subsequently being readable using a light source and a camera, the method including providing a mold with an array of individual areas of optical anisotropic surface structures, where at least a number of the individual optical anisotropic structures forms a two-dimensional barcode or data matrix; making a replica of the mold, the replica including the array having the property that the directional reflection coefficient of the individual areas of optical anisotropic surface structures is depending on the illumination angle and detection angle in a way that is not rotational symmetric around the axis normal to the surface of the replica, the array being readable by illumination and detection of reflection intensity of the illumination source under a non-normal angle to the surface of the replica.
摘要:
A method for disassembling a discarded refrigerator that uses a foamed resin as a heat insulator according to the present invention includes the processes of cutting and separating a heat-insulating housing of a refrigerator into pieces having a predetermined size and shape; obtaining the foamed resin by passing the pieces between a pair of compression rollers arranged so as to oppose each other and compressing the pieces, thereby peeling off and separating an incompressible plate-like object layered at least on one surface of the pieces; and collecting a foaming gas by passing the foamed resin (301) between a pair of compression rollers (331, 332) arranged so as to oppose each other and compressing the foamed resin, thereby allowing the foaming gas in the foamed resin to leak out. This makes it possible to collect a foaming gas in a heat insulator while maintaining a high concentration with small equipment at low cost.

摘要:
The present invention relates to a method for manufacturing a low density inorganic powder insulator having a low density molded structure using expanded perlite without a binder and a mold machine for manufacturing the same, and more particularly, to a technology of uniformly dispersing perlite particles having a shape of irregular fragments of glass using expanded perlite to form a framework among synthetic silica to improve molding strength even at a low density, thereby reducing thermal conductivity (conduction and convection blocking) due to a low density and an increase in a specific surface area. Further, the present invention relates to a method for manufacturing a low density inorganic powder insulator having a molded structure using economical expanded perlite having excellent physical properties by compression-molding a clad sheet material using a mold machine having a porous plate and a filter so as to remove pressure and air, which are generated during compression due to the use of the clad sheet material having low specific gravity and a large specific surface area, from a molded product or manufacturing the clad sheet material into a compressed clad sheet using a compression roller, and a mold machine for manufacturing the same.
