Production method for preparing high-added-value microporous ceramic from coal gangue
The invention discloses a production method for preparing high-added-value microporous ceramic from coal gangue in the industry of comprehensive utilization of industrial solid wastes. The method comprises the following steps of: separating high-silicon and high-aluminum raw materials by adopting a selective crushing process, adding a cross-linking agent, a dispersing agent, an initiator and water to form slurry, mixing a foaming agent-polyurethane AB two-component prepolymer with the slurry, and carrying out ball milling, foaming, gelling, drying, sintering and the like to obtain the microporous ceramic. The microporous ceramic has the characteristics of high apparent porosity, high compression strength, stable performance and the like. The microporous ceramic prepared by the method has the advantages of oxidation resistance, high temperature resistance, good adsorption performance and the like, and is wide in application and high in market value.
本发明公开了工业固体废物综合利用行业一种利用煤矸石制备高附加值微孔陶瓷的生产方法，该方法采用选择性破碎工艺分选出高硅、铝原料，并加入交联剂、分散剂、引发剂和水形成浆料，采用发泡剂‑聚氨酯AB双组份预聚体，将其与上述浆料混合，经过球磨、发泡、凝胶、干燥、烧结等，制备微孔陶瓷，该微孔陶瓷具有显气孔率高、压缩强度大、性能稳定等特性。该方法制备的微孔陶瓷具有抗氧化、耐高温、吸附性能好等优点，应用广泛，市场价值高。
