Title:
VACUUM HEAT INSULATION MATERIAL, METHOD FOR INSPECTING INTERNAL PRESSURE FAILURE OF VACUUM HEAT INSULATION MATERIAL AND METHOD FOR MANUFACTURING VACUUM HEAT INSULATION MATERIAL
Document Type and Number:
Japanese Patent JP2018100712
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material that can accurately measure internal pressure of a vacuum heat insulation material without installing a heat sink and complicating a configuration.SOLUTION: A vacuum heat insulation material includes: a core material; a testing layer disposed on the core material; and an exterior sheet for covering the core material and the testing layer so as to hermetically seal them, where the testing layer has a specific variation in coefficient of thermal conductivity.SELECTED DRAWING: Figure 2
