Porous ceramic prepared from mine solid waste and method
The invention provides a porous ceramic prepared from mine solid waste and a method for preparing the porous ceramic by using the mine solid waste, aiming at the problems that the porous ceramic prepared by an organic foam impregnation method is relatively low in porosity, non-uniform in bubble distribution and arrangement size, relatively thin in slurry adhesion thickness and the like. The porous ceramic is prepared by sintering a mixture of ceramic raw materials and additives, the ceramic raw materials comprise iron tailings and waste rock, and the additives comprise a binder, a rheological agent, a dispersing agent, a defoaming agent and a matrix modifier. The porous ceramic material provided by the invention is high in porosity and uniform in pore distribution and arrangement size, and open pores and closed pores can be switched along with temperature; according to the method, pore blockage can be effectively prevented while the adhesion thickness of the slurry is increased, and various properties of the porous ceramic are enhanced.
本发明是针对于有机泡沫浸渍法制备的多孔陶瓷孔隙率较低，气泡分布排列大小不均匀，浆料附着厚度较薄等问题，提供了一种利用矿山固废制备多孔陶瓷及方法。本发明的多孔陶瓷，由陶瓷原料和添加剂的混合物经烧结制得，陶瓷原料包括铁尾矿、废石，添加剂包括粘结剂、流变剂、分散剂、消泡剂、基体改性剂。本发明所提供的多孔瓷材料的孔隙率高，孔分布排列大小均匀，开孔和闭孔可随温度进行转换；该方法在提高浆料附着厚度的同时能更有效的防止发生孔隙堵塞，增强多孔陶瓷的各方面性能。
