摘要
分析了多孔含湿物料干燥过程中体积收缩产生的原因,实验研究了三种典型多孔物料体积收缩特性,讨论了多孔物料毛细孔半径、固体间架强度和外部干燥条件等对体积收缩率的影响。
In this paper,elementary mechanism and experimental results are analysed onthe volume shrin kage characteristics of the wet porous eapillary materials during drying process. Atthe same time, the influence is discussed of mean pore radius and solid matrix strength of the wetporous material,as well as the temperature and velocity of hot air on the volume shrinkage rate onthe basis of the experimental results.
