Description

technical field [0001] The invention relates to the field of non-metallic mineral materials, in particular to a phase-change heat storage calcium silicate board, a raw material and a preparation method and application thereof. Background technique [0002] Phase change energy storage is a new type of energy storage technology that has emerged in recent years and can improve energy utilization efficiency, save energy and improve the environment. Phase change materials will absorb or release a large amount of latent heat when the phase change occurs, and can adjust and control the temperature of the surrounding environment of the working source. It has the characteristics of approximately constant temperature during the phase change process, high energy storage density, and good thermal stability. Applied in the field of construction, it can adjust the comfort of the building's indoor environment, improve the function of building materials, and reduce building energy consumpti...
