Method for sintering porous ceramic by doping waste incineration fly ash into waste ceramic
The invention belongs to the technical field of harmless treatment of solid waste and waste incineration fly ash, and particularly discloses a method for sintering porous ceramic by doping waste incineration fly ash with waste ceramic. The method comprises the following steps: using waste ceramic powder, cement, clay, feldspar and fly ash as raw materials, adding foaming slurry, stirring, curing,and sintering to obtain the porous ceramic material. The porous ceramic product prepared by sintering is low in leaching toxicity; curing of heavy metals is realized, meanwhile, the thermal conductivity coefficient at normal temperature is low, the volume density is low, the porosity is high, the volume change after burning is small, the compressive strength is high, at the same time, the method has the characteristics of low cost, simple process and capability of realizing comprehensive utilization of resources, the problem of environmental pollution caused by waste ceramics and waste incineration fly ash is solved, secondary utilization of wastes is also realized, and the economic value is created.
本发明属于固体废弃物和垃圾焚烧飞灰无害化处理技术领域，具体公开了一种废弃陶瓷掺杂垃圾焚烧飞灰烧结多孔陶瓷的方法，以废弃陶瓷粉、水泥、黏土、长石和飞灰为原料，加入发泡浆液搅拌固化，通过烧结制得多孔陶瓷材料。所烧结制得的多孔陶瓷产品浸出毒性低，实现了重金属的固化，同时常温导热系数低、体积密度低、气孔率高、烧后体积变化小、耐压强度高，同时本发明具有成本低、工艺简单、能实现资源综合利用的特点，不仅解决了废弃陶瓷和垃圾焚烧飞灰的环境污染问题，还实现了废弃物的二次利用，创造了经济价值。
