    • An adsorbent capable of adsorbing gas low in activity such as nitrogen is used, and a thermal insulator high in production efficiency and excellent in adiabatic performance is presented. A thermal insulator has an adsorbent, a core material, and an enveloping member. The adsorbent includes Li and solid matter of hardness of 5 or more. The gas adsorbing activity becomes very high, and for embodiment by evacuating to a certain degree of vacuum by using a vacuum pump, the remaining gas is adsorbed by the adsorbent of the invention to obtain a desired degree of vacuum, so that a thermal insulator of high production efficiency is obtained. Since the heat conductivity is decreased by adsorbing gas of low activity in the enveloping member, the adiabatic performance is enhanced.
    • 使用能够吸附氮等低活性的吸附剂,具有制造效率高,绝热性优异的绝热材料。 绝热体具有吸附剂,芯材料和包封部件。 吸附剂包括Li和硬度为5以上的固体物质。 气体吸附活性变得非常高,并且通过使用真空泵将其抽真空至一定程度的真空,通过本发明的吸附剂吸附剩余的气体以获得所需的真空度,从而使绝热体 获得高生产效率。 由于通过在包络构件中吸附低活性气体来降低导热性,所以绝热性能得以提高。

    • A jacket material into which a gas adsorbing device and core material are inserted is decompressed in a vacuum chamber, the opening is sealed, and then the jacket material is exposed to the atmosphere. In the atmospheric pressure, a pressure of about 1 atm which is equivalent to the pressure difference between the inside and outside is applied to the jacket material of the heat insulator. The jacket material is made of a plastic laminated film and is deformed by pressure. A protruding portion is plunged into a container to drill through holes, and a gas adsorbent in the container communicates with the inside of the jacket material. Thus, both during holding and in applying to the vacuum heat insulator, the gas adsorbent can be applied to the vacuum heat insulator without degradation, and the high degree of vacuum can be kept for a long time.
    • 将气体吸附装置和芯材插入其中的护套材料在真空室中减压,开口被密封,然后外套材料暴露于大气中。 在大气压下,对绝热体的护套材料施加约1atm的压力,该压力等于内外压差。 护套材料由塑料层压膜制成,并通过压力变形。 将突出部分插入容器中以钻孔,并且容器中的气体吸附剂与护套材料的内部连通。 因此,在保持和施加到真空绝热器的同时,气体吸附剂可以被施加到真空绝热体而不会降解,并且可以长时间保持高真空度。
