Abstract：This thesis adopts full factorial design of the DOE(design of experiment) to explore the effects of four soluble salt ions (Na+,Mg2+,Cl- and K+) on the deformation of desulfurized gypsum board in high moisture environment,and the effect of each ion was analyzed by DOE analysis method. The results indicate that K+,Mg2+ and Na+ are significant factors affecting the sagging deformation of the desulfurized gypsum board in high moisture environment,in which Mg2+ and Na+ ions greatly will increase their sagging deflection,while K+ has the obvious inhibitory action on the deformation of desulfurized gypsum board,which is represented in reducing the sagging deformation of desulfurized gypsum board caused by adding of Na+ and Mg2+ ions.
