石膏基石蜡相变储能墙板的研究进展

摘要

Resource and energy consumption of buildings construction is large, building energy-saving should be implemented to improve energy efficiency. Energy can be stored by large heat fusion that phase change materials (PCM) release and absorb when phase change, and paraffin wax is safe, cheap PCM, having good chemical stability, large heat fusion and no super cooling, so it was choosed as PCM to be added to gypsum wallboards, which is low in production energy consumption, to get gypsum paraffin phase change energy storage wallboards. The domestic and foreign reaserch and development of PCM wallboards are introduced, and the preparation, packaging of paraffin composite used as PCM, manufacture process and related properties of PCM wallboards are reviewed.%建筑是资源和能源消耗大户,应实施建筑节能来提高能源利用效率.利用相变材料在相变过程中释放和吸收大量相变热可进行能量的存储,因石蜡是安全、无过冷、化学稳定性好、相变潜热较大且价廉的相变材料,将石蜡作为相变材料引入到生产能耗低的石膏墙板制作石膏基石蜡相变储能墙板具有重要意义.介绍了国内外相变储能墙板材料的研究现状,同时综述了石膏基石蜡相变储能墙板中石蜡相变材料的复配和封装、相变墙板的制作工艺及相关性能.
