TEMPERATURE MANAGEMENT MEMBER UNDER REDUCED-PRESSURE ATMOSPHERE, AND TEMPERATURE MANAGEMENT METHOD UNDER REDUCED-PRESSURE ATMOSPHERE

摘要

Under the reduced atmosphere for providing a kind of temperature management component, the discoloring temperature of difference heat discoloration layer can be minimized under atmospheric pressure atmosphere and in reduced atmosphere. Temperature management component has temperature sensing color changing layer (12) in reduced atmosphere Nei Let, it includes graininess or powdery hot-melt objects (22), the heating temperature of first fusion temperature is decolourized in the case where corresponding to reduced atmosphere to be detected, and in response to the hot melt, with difference melting temperature hot-melt object (22) heat discoloration layer (12) under atmospheric pressure atmosphere and 5 °C of reduced atmosphere at most.
