Method for preparing honeycomb ceramic oxygen permeation membrane through extrusion forming
The invention provides a method for preparing a honeycomb ceramic oxygen permeation membrane through extrusion forming. The preparation process comprises the following steps: preparing oxygen permeable membrane powder; preparing a pug blank; preparing a honeycomb ceramic oxygen permeation membrane; drying and shaping; and high-temperature sintering. On the basis of a honeycomb ceramic structure, the ceramic oxygen permeation membrane with the honeycomb structure is prepared by utilizing an extrusion forming method, the interior of the oxygen permeation membrane with the novel structure is honeycomb-shaped parallel channels, and the unit channels effectively guarantee the mechanical strength of the oxygen permeation membrane. In addition, the oxygen permeation membrane with the novel structure has the advantages of large membrane area per unit volume, easiness in sealing and the like. The method is simple in operation steps, high in production efficiency and beneficial to large-scale production and application.
本发明提供了一种挤压成型制备蜂窝陶瓷透氧膜的方法。制备过程包括以下步骤：透氧膜粉体制备；泥料胚体制备；蜂窝陶瓷透氧膜制备；干燥定型；高温烧结。本发明是在基于蜂窝陶瓷结构基础上，利用挤压成型方法制备得到具有蜂窝结构的陶瓷透氧膜，该新型结构透氧膜内部是蜂窝形状平行通道，这些单元通道有效保证了透氧膜的机械强度。另外，该新型结构透氧膜同时具有单位体积膜面积大、易密封等优点。本发明操作步骤简单、生产效率高，有利于实现大规模生产应用。
