一种复合管式膜烧结模具
本技术涉及材料的烧结装置,特别涉及一种复合管式膜烧结模具。
技术介绍
复合管式膜是一种新型的分离膜,通过在多孔管式膜基材上涂覆不同材质的表面有机膜层制得,多孔管式膜起支撑作用,分离效果主要由表面有机膜层决定,复合管式膜同时具备高通量和高过滤精度的优点。公开号为CN102008899B的中国专利技术专利中提到了一种管式膜烧结模具,该模具由空心无缝钢管和小直径实心无缝管管体构成,小直径实心无缝管管体插入空心无缝钢管中间形成一个圆环,聚合物混合粉料填充到圆环中压紧经烧结后形成多孔管式膜支撑体,该模具的缺点在于不能直接制备复合管式膜,只能得到多孔管式膜支撑体,要制备复合管式膜,还需要另外在多孔管式膜支撑体上涂覆一层有机膜层,不仅耗时长,而且有机膜层的均一性也不是很理想。
