Casting silicon carbide-mullite porous ceramic filter based on direct-writing forming 3D printing and preparation method
The invention provides a silicon carbide-mullite porous ceramic filter for casting based on direct-writing forming 3D printing and a preparation method, and the method comprises the following steps: uniformly mixing waste silicon carbide refractory material fine powder, alumina micro powder, silica powder, a catalyst, a dispersant, an inorganic binder and water to prepare slurry, and removing gas in the slurry under a vacuum condition to obtain the silicon carbide-mullite porous ceramic filter for casting. A silicon carbide-mullite porous ceramic filter green body is obtained through direct-writing forming 3D printing, drying and baking, and then the silicon carbide-mullite porous ceramic filter is prepared through calcination under the carbon burying condition. The method is simple in process and low in cost, and resource utilization of the industrial solid waste is realized. The prepared silicon carbide-mullite porous ceramic filter has the advantages of controllable pore structure, high porosity, high mechanical strength, stable high-temperature performance and the like.
本发明提供了一种基于直写成形3D打印的铸造用碳化硅‑莫来石多孔陶瓷过滤器及制备方法，该方法为：将废弃碳化硅耐火材料细粉、氧化铝微粉、硅微粉、催化剂、分散剂、无机粘结剂和水混均匀，制得浆体，并真空条件下将去除浆料中的气体，采用直写成形3D打印并经干燥、烘烤后得到碳化硅‑莫来石多孔陶瓷过滤器坯体，再在埋碳条件下煅烧制得碳化硅‑莫来石多孔陶瓷过滤器。本发明工艺简单，成本低廉，并实现了工业固废资源化利用。所制备的碳化硅‑莫来石多孔陶瓷过滤器具有孔隙结构可控、孔隙率高、机械强度高且高温性能稳定等优点。
