Preparation method of attapulgite clay-based porous ceramic support body
The invention relates to a preparation method of an attapulgite clay-based porous ceramic support body, which comprises the following steps: by using attapulgite clay mineral powder and aluminum oxidepowder as raw materials, adding water, an adhesive, a pore forming agent and an assistant, and performing stirring, aging, extruding, sintering and the like processes to prepare the attapulgite clay-based porous ceramic support body. The three-point bending strength of the support prepared by the support prepared by the method is 20-35 MPa, the porosity is 32%-40%, the average pore size is 1.5-2.5 [mu]m, and the pure water flux is 1550-2150 L/m<2>*h*Mpa. The preparation method has the advantages of low raw material cost and low sintering temperature, and provides a new way for solving the problem of high cost of support preparation.
本发明涉及一种凹凸棒石粘土基多孔陶瓷支撑体的制备方法：以凹凸棒石粘土矿粉与氧化铝粉末为原料，加入水、粘结剂、造孔剂、助剂，经搅拌、陈化、挤出、烧结等工艺制备出凹凸棒石粘土基多孔陶瓷支撑体，本发明得到的支撑体制备出的支撑体三点抗弯曲强度为20~35MPa，孔隙率为32%~40%，平均孔径为1.5μm~2.5μm，纯水通量为1550~2150 L·m‑2·h‑1·Mpa‑1。本发明原料成本低，烧结温度低，为解决支撑体制备高成本的问题提供了一条新途径。
