Preparation method of mullite porous microfiltration membrane support ceramic
The invention relates to the technical field of comprehensive utilization of environment-friendly solid wastes, and discloses a preparation method of mullite porous microfiltration membrane support ceramic, and the mullite porous microfiltration membrane support ceramic is prepared according to the following raw material formula: 5-15 parts of Al2O3 powder; 60 to 75 parts of high-alumina fly ash; 10 to 20 parts of a co-sintering type composite pore-forming agent; 0.5 to 5 parts of polyvinyl alcohol; and 12.5 to 120 parts of purified water. The preparation method comprises the following steps: adding the raw materials according to the ratio into a ball milling tank, drying after ball milling to obtain powder, granulating and sieving the powder, taking the powder for dry pressing molding to prepare a green body, drying, and sintering in a high-temperature electric furnace to obtain the mullite porous microfiltration membrane support ceramic. The sintering temperature is reduced by more than 300 DEG C compared with that of aluminum oxide ceramic, the use amount of aluminum oxide can be reduced by 80%, and the production cost is greatly reduced.
本发明涉及环保固废综合利用技术领域，且公开了一种莫来石多孔微滤膜支撑体陶瓷制备方法，按照下述原料配方配比莫来石多孔微滤膜支撑体陶瓷的原料，该原料配方为：Al2O3粉料、5‑15份；高铝粉煤灰、60‑75份；助烧结型复合造孔剂、10‑20份；聚乙烯醇、0.5‑5份；纯化水、12.5‑120份；将上述配比的原料加入球磨罐内，球磨之后干燥得到粉料，对该粉料进行造粒，过筛，取粉体用于干压成型，制成生坯，干燥之后置于高温电炉中烧结，得到莫来石多孔微滤膜支撑体陶瓷。本发明的烧结温度比氧化铝陶瓷降低了300℃以上，氧化铝用量可减少80％，极大降低了生产成本。
