Title:
HEAT INSULATION STRUCTURE AND HEAT INSULATION STRUCTURE HAVING HUMIDIFIER
Document Type and Number:
Japanese Patent JP2022060684
Kind Code:
A
Abstract:
To provide a heat insulation structure which can hold heat insulation performance at a high temperature of 150°C to 260°C without generating gas which causes an erroneous operation of a gas detector.SOLUTION: A heat insulation structure 11 has a porous polytetrafluoroethylene resin foaming molding having a shape corresponding to a shape of a heat insulation object, the porosity of the porous polytetrafluoroethylene resin foaming molding is equal to or higher than 60% and lower than 80%, a thickness is equal to or thicker than 6 mm, and equal to or thinner than 100 mm. An average grain diameter of pores of the porous polytetrafluoroethylene resin foaming molding is equal to or larger than 80 μm, and equal to or smaller than 120 μm.SELECTED DRAWING: Figure 1
