Silicon carbide ceramic membrane and preparation method and application thereof
The invention discloses a silicon carbide ceramic membrane and a preparation method and application thereof and the silicon carbide ceramic membrane. The silicon carbide ceramic membrane comprises a support body and a membrane layer connected with the support body, wherein the support body comprises the following raw materials in parts by weight: 85-92 parts of silicon carbide, 6-10 parts of a pore forming agent, 8-15 parts of a firing binding agent and 3-8 parts of a forming aid, the film layer is prepared from the following raw materials in parts by weight: 70 to 90 parts of emery, 10 to 30parts of a firing binding agent, 10 to 20 parts of a pore forming agent, 38 to 50 parts of water, 0 to 0.3 part of a dispersing agent and 0 to 0.3 part of a suspending agent, wherein the sintering binding agent comprises the following components in parts by weight: 76-96 parts of Zhangcun soil, 5-16 parts of dolomite and 3-16 parts of glass fiber powder. The sintering temperature of the support body is reduced by changing a formula system of the support, and the sintering temperature of the support body and the film layer is controlled within the same temperature interval, so that the film layer and the support body are sintered at one time, and the original twice sintering of the support body and the film layer is replaced.
本发明公开了一种碳化硅质陶瓷膜及其制备方法和应用，碳化硅质陶瓷膜，包括支撑体以及与支撑体连接的膜层；所述支撑体，按重量份数计，包括以下原料：碳化硅85～92份；造孔剂6～10份；烧成结合剂8～15份；成型助剂3～8份；所述膜层，按重量份数计，包括以下原料：刚玉砂70～90份、烧成结合剂10～30份、造孔剂10～20份、水38～50份、分散剂0～0.3份、悬浮剂0～0.3份；其中：烧成结合剂，按重量份数计，包括:章村土76‑96份，白云石5‑16份，玻纤粉3‑16份。通过改变支撑的配方体系降低支撑体烧成温度，将支撑体与膜层烧成温度控制在相同温度区间内，实现膜层与支撑体一次烧成，代替原有支撑体和膜层两次烧成。
