<P>PROBLEM TO BE SOLVED: To provide a combination type heat retention material (heat insulation material) which is markedly suitable for temperature retention (heat insulation) of pipe, device or the like in a narrow space in which the pipe, device and the like are intricate, and additionally can exhibit high heat retention (heat insulation) effect despite its compactness according to the request and further can markedly reduce the generation of impurities such as dusts and gas, so called particles. <P>SOLUTION: The combination type heat retention material can be configured such that a plurality of planar heat retention materials having substantially the same rectangular shapes one another, in which the length ratio of a width edge to a length edge is approximately 1 to 2, on front and back surfaces are combined by connecting arbitrary edges of the planar heat retention materials to each other, rectangular shapes of the plurality of heat retention materials are the same or similar to one another and, when the rectangular shapes of the plurality of heat retention materials are similar to one another, the length ratios of corresponding length edge and width edge of a rectangle of large heat retention material to the length edge and width edge of a rectangle of small heat retention material are multiple of 1 to 2 in both. <P>COPYRIGHT: (C)2013,JPO&INPIT |
