【摘要】：脫硫石膏煅燒處理工藝的好壞直接關(guān)系到脫硫石膏的性能和應(yīng)用。以煅燒溫度、煅燒時(shí)間、交互作用為主要因素,設(shè)計(jì)3因素3水平正交試驗(yàn),研究各因素對(duì)脫硫石膏抗壓、抗折強(qiáng)度的影響。結(jié)果表明:當(dāng)煅燒溫度達(dá)到350℃時(shí),抗壓、抗折強(qiáng)度顯著提高;煅燒時(shí)間為3h時(shí),抗壓、抗折強(qiáng)度達(dá)到最大值,絕干狀態(tài)下抗壓、抗折強(qiáng)度分別達(dá)到20.60MPa、6.90MPa,吸水飽和狀態(tài)下抗壓、抗折強(qiáng)度分別達(dá)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，
