在试验室利用赤泥、水泥、粉煤灰、粘结剂等为原材料,经配比混合、成型发泡、烧结等工艺制备发泡陶瓷保温材料。研究烧结温度对材料性能的影响;利用SEM电镜观察试样的微观形貌,并进行机理分析。试验室试验结果表明,在本试验条件下的最佳烧结温度为1120℃,试样抗折强度为0.41MPa、抗压强度1.15MPa,密度达到479kg/m3。 Red mud, cement, fly ash, binder and other raw materials are used in the laboratory to prepare foamed ceramic thermal insulation materials through the processes of mixing, forming, foaming and sintering. The effect of sintering temperature on the material properties was investigated. The microstructure of the samples was observed by SEM and the mechanism was analyzed. Laboratory test results show that the optimum sintering temperature under this test condition is 1120 ℃, the sample flexural strength is 0.41MPa, the compressive strength is 1.15MPa and the density is 479kg / m3.
