Production method and production system of silicon carbide honeycomb ceramic material
The production method comprises the following steps that S1, silicon carbide raw material particles are put into a ball mill, absolute ethyl alcohol is added for wet grinding, a product is filtered and dried, silicon carbide powder is obtained, the silicon carbide powder is filtered and screened, and it is guaranteed that the diameter of the silicon carbide powder ranges from 1 micrometer to 2 micrometers; s2, the silicon carbide powder is added into a mixing machine, a sintering aid, a dispersing agent and a forming medium are added into the mixing machine, a honeycomb blank with parallel pore channels is prepared and dried, and the addition amount of the silicon carbide powder accounts for 60-75 wt% of the total powder; the sintering aid comprises alumina powder and yttrium oxide powder, the addition amount of the alumina powder is 2-5wt% of the total powder, and the addition amount of the yttrium oxide powder is 5-10wt% of the total powder; and S3, removing organic matters from the honeycomb green body obtained in the step S2 in a heat treatment manner, wherein the heating temperature is 600-700 DEG C. The prepared silicon carbide honeycomb ceramic material is high in efficiency and good in automobile exhaust treatment effect.
本发明公开了一种碳化硅蜂窝陶瓷材料生产方法及其生产系统包括以下步骤：S1:通过碳化硅原料颗粒投入球磨机中，加入无水乙醇进行湿磨，过滤产物并干燥，得到碳化硅粉末，并对碳化硅粉末过滤筛分，保证碳化硅粉末直径为1μ‑2μm；S2:碳化硅粉末加入至混合机中，并向混合机中加入助烧剂，分散剂和成型介质，制备具有平行孔道的蜂窝坯体并干燥，碳化硅粉末添加量为总粉体的60‑75wt％；所述助烧剂为氧化铝粉和氧化钇粉体，氧化铝粉添加量为总粉体的2‑5wt％，氧化钇粉添加量为总粉体的5‑10wt％；S3：将通过热处理的方式对S2中得到的蜂窝坯体进行有机物排除，加热温度为600‑700摄氏度。本发明本发明制备的碳化硅蜂窝陶瓷材料效率高，且汽车尾气处理效果好。
