尾矿制备相变材料研究进展
Research Progress on Tailings-based Composite Phase Change Materials
摘要
Abstract
Mining industry produces a large amount of tailings annually in China.Currently,the treatment of tailings mainly includes mine backfill and valuable metal recovery.Which is difficult to realize the full utilization of tailings.The tailings contain quartz,feldspar,carbonate,silicate,and clay minerals,bestows them with good stability,a large specific area and rich pore structure.Solid-liquid phase change materials(solid-liquid PCMs)exhibit significant latent heat.However,they are prone to leakage during solid-liquid phase transition process.Utilizing tailings as carriers to load solid-liquid PCMs not only addresses the issue of leakage but also provides a valorization method for the resource utilization of tailings and reduces the burden on the ecological environment.Aiming at the resource utilization of tailings,this paper reviewed the types and physicochemical properties of tailings,the encapsulation,and preparation of tailings-based phase change materials,thermal property enhancement,and practical applications.Finally,the shortcomings of the current preparation of phase change materials from tailings and the outlook for future research were described.This information can serve as a useful reference for researchers and help advance the progress of utilizing tailings as a resource for phase change heat storage.关键词
