| Abstract: |
| Experimental study was carried out to explore the preparation of fire insulation ceramic facades material prepared by iron tailings and waste rock. ICP-AES analysis, chemical analysis, X-ray diffraction analysis, TG-DSC thermal analysis and radio activity detection of iron tailings and waste rock were detected. And then the relationship between material properties and the preparation of ratio of raw materials, raw material grinding fineness, foaming agent, particle size of foaming agent, firing system were studied. The results show: It was technology feasible for preparing building facades fire insulation ceramic materials qualified with radioactive iron tailings and waste rock. Suitable materials ratio of iron tailings is 40 to 55% and feldspar amount is 45 to 60%. The amount of blowing agent is mixed with 0.5%.The raw material grinding fineness control is 7.45μm (D50) around; The foaming agent grinding fineness is 0.037mm.The sintering temperature is 1160℃ and the sintering time is 60min. The dry density of prepared material was 350kg / m3. Water absorption was 0.48%. The thermal conductivity was 0.09W/(m ? K). The compressive strength was 4.20MPa, Flexural strength was 1.46MPa. Fire-proof level was A. |
