Al_2O_3-SiO_2气凝胶隔热材料的研究进展
|
摘要
Al_2O_3-SiO_2气凝胶因具有低密度、高比表面积、低导热系数以及高温稳定性等优良性能,成为理想的轻质隔热材料,具有广泛的应用前景。主要介绍了Al_2O_3-SiO_2气凝胶隔热材料的制备方法、隔热机理及其发展趋势,指出了未来的研究方向。该研究对储罐隔热材料的研究及应用具有一定的指导意义。
Because of low density,high specific surface area,low thermal conductivity and high temperature stability,Al_2O_3-SiO_2 aerogel has become an ideal lightweight heat insulating material and has a wide range of applications.This paper mainly introduces the preparation methods,thermal insulation mechanism and development trend of Al_2O_3-SiO_2 aerogel insulation material,and points out the research directions in the future.The paper has guidance significance for the study and application of insulation materials of storage tanks.
