摘要
硅藻土是一种多孔矿物材料,具有储量丰富、价格低廉、吸附能力强等优点,是相变储能材料(Phase change material:PCM)的优良载体。当前,发展高性能硅藻土基PCM的关键是提高其相变潜热和导热系数,对比了硅藻土基PCM通过不同的改性技术提高相变材料负载量的方法、综述了硅藻土基PCM热物性,尤其是通过强化导热提高储放热效率的研究进展,最后指出了硅藻土基PCM在应用研究方面的研究现状,对未来研究方向进行了展望。
As a kind of porous clay mineral material,diatomite has some advantages like rich reserves,low cost,and high specific surface area,which can be used as an excellent carrier of phase change material(PCM).Recent work on high-efficiency diatomite PCM is to improve its latent heat and thermal conductivity.This review represented recent research progress on the specific surface area modification and thermal conductivity enhancement modification of diatomite PCM and analyzed the thermal properties of diatomite with different types and contents of PCMs.In addition,some problems of diatomite PCM application were described,and the future research directions were prospected.
