【摘要】：脱硫石膏煅烧处理工艺的好坏直接关系到脱硫石膏的性能和应用。以煅烧温度、煅烧时间、交互作用为主要因素,设计3因素3水平正交试验,研究各因素对脱硫石膏抗压、抗折强度的影响。结果表明:当煅烧温度达到350℃时,抗压、抗折强度显著提高;煅烧时间为3h时,抗压、抗折强度达到最大值,绝干状态下抗压、抗折强度分别达到20.60MPa、6.90MPa,吸水饱和状态下抗压、抗折强度分别达到9.97MPa、3.55 MPa。
[Abstract]:The calcination process of desulphurized gypsum is directly related to the performance and application of desulphurized gypsum. Taking calcination temperature, calcination time and interaction as the main factors, three factors and three horizontal orthogonal tests are designed to study the pressure resistance of each factor to desulphurized gypsum. The results show that when the calcination temperature reaches 350 鈩，
