  • Publication number: 20200200317
    Abstract: A vacuum heat insulating material is provided with: a sheath material; and a core material that is sealed inside the sheath material in a hermetically sealed decompressed state. The sheath material includes a gas barrier layer containing a layered material. The sheath material is configured such that a product d×E of a thickness d (unit: mm) and a tensile modulus E (unit: Pa) of the sheath material is set to be less than or equal to 600 MPa·mm, the tensile modulus being measured with a dynamic viscoelasticity measuring device. Accordingly, it is possible to provide a vacuum heat insulating material capable of effectively preventing the brittleness of the sheath material including the gas barrier layer that contains the layered material.

A carbon dioxide adsorbent including at least a ZSM-5 zeolite including barium (Ba) or strontium (Sr) is characterized in that the ZSM-5 zeolite includes M-O-M bonds (M being Ba or Sr, and O being oxygen). The M-O-M bonds interact strongly with carbon dioxide, and thus carbon dioxide can be adsorbed effectively and in large volumes even under conditions having low carbon dioxide concentrations.

  • Patent number: 8942402
    Abstract: An acoustic speaker device (10) according to the present invention comprises at least two types of gas adsorption materials in a cabinet (12) thereof. A porous carbon material package member (14A), which is one of the gas adsorption materials, can adsorb or eliminate air in the cabinet (12) by a porous carbon material (41) during the operation of a speaker unit (13) so as to buffer compression or expansion of air in the cabinet (12). A sheet-like moisture adsorbing material (14B), which is the other of the gas adsorbing materials, is formed by dispersing copper ion-exchanged ZSM-5 zeolite (43) in a thermoplastic resin composition (44), and is stuck on at least a section of an inner wall of the cabinet (12). This configuration allows moisture in the cabinet (12) to be rapidly adsorbed.
