Vacuum thermal-insulation material, and a device and method for assessing the degree of vacuum in the vacuum insulation material by using the frequency response method
摘要:
Disclosed herein is a vacuum insulation material, which includes a barrier film and a core, wherein a rigid body thinner than a reference thickness or a getter harder than a reference hardness is formed between the barrier film and the core, or the rigid body thinner than the reference thickness is formed on the getter formed between the barrier film and the core to ensure surface flatness and surface hardness of the vacuum insulation material.
