Method for producing porous ceramic by using ceramic filter plate waste
The invention relates to the technical field of ceramic reproduction, in particular to a method for producing porous ceramic by using ceramic filter plate waste. S1.1, after the recycled scrapped ceramic filter plate is cleaned up with an acidic cleaning solution, the ceramic filter plate is put into a crusher to be crushed into ceramic powder; s1.2, the ceramic powder, the soil powder, the coal ash powder, the boric acid and the CMC are put into a ball mill according to the proportion of (50-60): (20-30): (10-20): (2-5): (1-2); s1.3, uniformly mixing 6-10 parts by weight of a plant fiber pore-forming agent and 10-20 parts by weight of a reinforcing phase into the sieved powder; s1.4, adding CMC (Carboxymethyl Cellulose) and water into the uniformly stirred powder, and granulating; s1.5, adding the granulation powder into a mold, and pressing to form a primary blank; s1.6, the primary blank is fed into a curing room at the temperature of 40-60 DEG C to be cured; and S1.7, putting the cured primary blank into a sintering furnace for sintering at 1300-1400 DEG C to obtain the porous ceramic product. Through APTES modified alpha-alumina nanoparticles, the dispersity of the nanoparticles in a ceramic matrix is optimized, and the compressive strength and impact toughness of the porous ceramic are effectively improved.
本发明涉及陶瓷再生产技术领域，具体地说，涉及一种利用陶瓷过滤板报废品生产多孔陶瓷的方法。S1.1、将回收的报废陶瓷过滤板用酸性清洗液清洗干净后，投入破碎机里破碎成陶瓷粉料；S1.2、将陶瓷粉料、土粉、煤灰粉、硼酸和CMC以50～60:20～30:10～20:2～5:1～2的比例投入球磨机；S1.3、将6‑10重量份的植物纤维成孔剂和10‑20重量份的增强相一起均匀混入已过筛的粉料中；S1.4、将搅拌均匀的粉料加入CMC和水进行造粒；S1.5、将造粒粉加入模具中压制成型初坯；S1.6、将初坯送入40‑60℃的养护房养护；S1.7、将养护完成的初坯放入烧结炉1300‑1400℃烧结，即得到多孔陶瓷制品。通过APTES改性的α‑氧化铝纳米粒子不仅优化了纳米粒子在陶瓷基体中的分散性，有效提升多孔陶瓷的抗压强度和冲击韧性。
