黏土矿物具有孔隙结构突出,吸附性能和导热性能良好等特性,将其作为相变材料的载体能够有效抑制相变材料的相变泄露,改善相变材料的热物性,拓宽相变材料的应用领域。然而,原始黏土矿物对相变材料的吸附能力仍较弱,形成的黏土矿物基定形复合相变材料的储热性能还有待提高。综述了改性黏土矿物基定形复合相变材料储热性能的研究进展,展望了黏土矿物基定形复合相变材料储热性能的发展前景。
Clay minerals have outstanding pore structure,good adsorption performance and good thermal conductivity.Using them as a carrier of phase change materials can effectively inhibit the phase change leakage of the materials,and improve the thermal properties of the materials,and broaden their application fields.However,the adsorption capacity of the original clay minerals to phase change materials is still weak,and the heat storage performance of the formed clay mineral-based forming composite phase change materials needs to be improved.The research progress of the heat storage performance of modified clay mineral-based forming composite phase change materials was reviewed,and prospected the development prospects of the heat storage performance of the materials.
