Method for preparing high-performance insulating brick from solid waste sludge
The invention discloses a method for preparing a high-performance insulating brick from solid waste sludge. The method comprises the following specific steps: (1) mixing coal gangue, iron tailings, shale and boron magnesium sludge, adding the formed mixture into solid waste sludge, and carrying out uniform stirring to obtain mixed sludge; (2) partially dehydrating the mixed sludge, adding a fluxing agent and a pore-forming agent, carrying out uniform mixing, and putting the formed mixture into a hydraulic forming machine to prepare a green brick; and (3) drying the green brick, and firing the green brick in a kiln to obtain the insulating brick. According to the preparation method provided by the invention, the pore-forming agent is added to prepare the insulating brick, so the problems of low activity and difficult forming of solid waste raw materials such as sludge are solved, the additional value of a sludge-based sintered brick is improved, and the application range of the sludge-based sintered brick is widened. The insulating brick prepared by the preparation method provided by the invention also has excellent heat-insulating property and compression resistance, and the sludge is used for making the brick, so pollution is eliminated, resources are saved, an urban environment is protected, the reutilization of the waste is effectively realized, and good economic benefits can be brought.
本发明公开了一种利用固废淤泥制备高性能保温砖制备的方法，具体步骤为：(1)将煤矸石、铁尾矿、页岩和硼镁泥混合后加入至固废淤泥中搅拌均匀后制得混合淤泥；(2)将混合淤泥部分脱水后加入助熔剂和成孔剂，混合均匀后放入液压成型机中制成砖坯；(3)将砖坯烘干后放入炉窑中烧制即可制得所述保温砖。本发明所提供的制备方法以外加成孔剂制作保温砖，克服了淤泥等固体废弃物原料活性低、成型困难的难题，为淤泥基烧结砖提高附加值，拓宽其应用范围。本发明所提供的制备方法制得的保温砖还具有优异的保温性能和抗压性能，利用淤泥制砖，不仅消除污染，还节约了资源，保护了城市环境，有效地实现废物再次利用，能够带来良好的经济效益。
