Vacuum insulating material, refrigerator using vacuum insulating material.
摘要
<p>A vacuum insulating material which minimizes the possibility of absorption of moisture or gas components by its core material during storage in the manufacturing process, improves manufacturing efficiency, and maintains and enhances heat insulation performance. A vacuum insulating material comprises: a core material (21) as an inorganic fiber aggregate; an absorbent (22) which absorbs core material gas components; and an envelope (24) with a gas barrier property which encases the core material. The absorbent (22) is contained in a housing area (21a) made by slitting the core material (21) obliquely with respect to its surface or thickness and the opening of the housing area (21a) is narrowed by overlapping.
