Equilibrium moisture model of ceramic green body during drying

Abstract

The drying stage of ceramic green body is crucial in the production process, and the equilibrium moisture content achieved by green body drying is very important for the green body firing stage. Based on the modified Oswin equilibrium moisture model, the influence of hot air temperature and relative humidity on the equilibrium moisture content of SiO2 and Al2O3 ceramic composite green body drying was studied through hot air drying experiments, and according to the experimental data, the equilibrium moisture content data was fitted by the least squares method to determine the equilibrium moisture content model.
