According to actual needs, relatively beautiful plank is selected, therefore high-strength plate can beautify the appearance of phase-transition heat-preserving material.Heat-insulating shield due to
Its thermal coefficient is low, therefore heat-insulating shield can cooperate with phase-change material layers, plays the role of mutually enhancing on heat insulation effect.
It is not the process of a mutation, so in phase-transition heat-preserving since the phase transition process of phase-change heat-preserving board is a lasting process
During the entire process of plate phase transformation, temperature of the heat-insulating shield close to the side of phase-change heat-preserving board substantially remains in phase transition temperature, and adiabatic
The temperature of side of the plate far from phase-change heat-preserving board is environment temperature.In this case, the work(of the decrease heat transfer of heat-insulating shield
It can be strengthened.
The phase-change heat-preserving board prepared through this embodiment can accurately adjust temperature, have the purposes extensively sent out very much.For example, phase
Temperature is that 5 DEG C of phase-change heat-preserving board is suitable for preparing medical cold chain transportation case, is stored in 2~8 DEG C of environment for needing
The storage and transport of drug.In another example the phase-change heat-preserving board that phase transition temperature is 28 DEG C is suitable for construction material external wall insulation, it can
