Method for preparing porous material from sulfur-containing solid waste and method for curing sulfur
The invention relates to a method for preparing a porous material from sulfur-containing solid waste and curing sulfur. The porous material is prepared from 70.0 to 90.0 weight percent of sulfur-containing solid waste, 1.0 to 5.0 weight percent of feldspar, 5.0 to 15.0 weight percent of dolomite, 2.0 to 20.0 weight percent of silica, 0 to 2.0 weight percent of foaming agent and 0 to 3.0 weight percent of fluorite powder. According to the invention, sulfur is synergistically fixed through a porous material pore-glass phase-crystal phase multi-scale structure, the curing rate of sulfur is greater than or equal to 85%, and the porous material can be used in the fields of buildings, pipeline equipment, sound insulation, composite heat insulation systems and the like, can also be used as an environmental material for curing sulfur-containing solid wastes (medium-high sulfur coal gangue, waste incineration fly ash and the like), and has a wide application prospect. And harmless treatment and resource utilization of the sulfur-containing solid waste are realized.
本发明涉及一种含硫固废制备多孔材料及固化硫的方法，所述的多孔材料由含硫固废70.0～90.0wt％、长石1.0～5.0wt％、白云石5.0～15.0wt％、硅石2.0～20.0wt％、发泡剂0～2.0wt％、萤石粉0～3.0wt％制备而成。本发明通过多孔材料气孔‑玻璃相‑晶相多尺度结构协同固硫，实现硫的固化率≥85％，该型多孔材料可用于建筑、管道设备、隔音和复合隔热系统等领域，也可以作为环境材料固化含硫固体废弃物(中高硫煤矸石、垃圾焚烧飞灰等)，实现含硫固废的无害化处置协同资源化利用。
