Method for preparing large-size foamed ceramic from solid waste
The invention discloses a method for preparing large-size foamed ceramic from solid waste, and belongs to the technical field of new building materials. The method comprises the following steps: adding water into a mixed material of metal tailings, urban construction waste, river sludge, bentonite and a foaming optimizer, and carrying out wet ball milling to obtain slurry; carrying out filter pressing, vacuum pugging and extrusion molding on the slurry to prepare a hollow honeycomb-shaped green body; drying the green body; and putting the mixture into refractory castable kiln furniture for high-temperature sintering to obtain the foamed ceramic. The preparation method is simple and has the advantages of low investment and low energy consumption; the industrial solid waste tailings are used as the main raw material, and the urban construction waste and the river sludge are used as auxiliary materials, so that the solid waste utilization rate can reach 90% or above.
本发明公开了一种利用固废制备大尺寸发泡陶瓷的方法，属于建筑新材料技术领域。该方法为向金属尾砂、城市建筑垃圾、河道淤泥、膨润土和发泡优化剂的混合物料中加入水，湿法球磨得到浆料；将浆料进行压滤、真空练泥、挤出成型，制得中空蜂窝状坯体；坯体烘干；放入耐火浇注料窑具内高温烧结，得到发泡陶瓷。该制备方法简单，具有低投资低能耗的优点；且以工业固废尾砂为主要原料，辅以城市建筑垃圾和河道淤泥，固废利用率可达到90％以上。
