Method for preparing gradient density microcrystal foaming ceramic by utilizing industrial solid waste
The invention relates to the technical field of foamed ceramic preparation, in particular to a method for preparing gradient density microcrystal foamed ceramic by using industrial solid waste, which comprises the following steps: by using aluminum-silicon industrial solid waste as a main raw material, adding 3-15% of refractory brick waste as a foam stabilizer and 2-10% of a composite pore-forming agent composed of electrolytic manganese residue, graphite tailings and silicon carbide micro powder; the preparation method comprises the following steps: mixing the raw materials by dry ball milling to prepare uniform powder, filling the powder into a refractory mold, and carrying out high-temperature heating, partitioned temperature control foaming, cooling and cutting to prepare the microcrystal foamed ceramic with gradient density change. According to the method for synergistically preparing the gradient-density microcrystal foamed ceramic by utilizing various solid wastes, one-time sintering of the multi-density composite microcrystal foamed ceramic is realized, and high-added-value utilization of various industrial solid wastes is promoted.
本发明涉及发泡陶瓷制备技术领域，具体涉及一种利用工业固体废弃物制备梯级密度微晶发泡陶瓷的方法，铝硅质工业固体废弃物为主要原料，添加3～15％耐火砖废料作为稳泡剂，2～10％由电解锰渣、石墨尾矿、碳化硅微粉构成的复合造孔剂，0.1～0.5％三乙醇胺，经干法球磨混合制成均匀的粉料，将粉料装填在耐火模具内，经高温加热、分区控温发泡、冷却切割，制备出密度梯级变化的微晶发泡陶瓷。这种利用多种固体废弃物协同制备梯级密度微晶发泡陶瓷的方法，既实现了多密度复合微晶发泡陶瓷的一次烧成，又促进了多种工业固体废弃物的高附加值利用。
