日本三菱重工业公司和日本碍子公司正在共同开发用于分离冷凝性气体的陶瓷膜.这种膜是在厚约1毫米的多孔性基质表面涂覆厚10微米超微细孔薄膜而构成的,它与传统的高分子功能膜相比,具有渗透速度和选择性高、不会被各种溶剂膨润的特点,预期将有广泛用途,可用于溶剂回收装置等机械设备、共沸点混合物的分离,乙醇的回收和食品工业等方面。这两家公司共同开发的陶瓷膜分离功能的机制(以分离空气中的水份为例说明),大致
Japan’s Mitsubishi Heavy Industries, Ltd. and Japan’s Adolescents are jointly developing a ceramic membrane for the separation of condensable gases. This membrane is formed on a porous substrate with a thickness of about 1 mm and coated with a 10 μm thick microporous film, Compared with the traditional polymer functional membrane, it has the characteristics of high permeation rate and high selectivity and can not be swollen by various solvents. It is expected to be used for a wide range of applications such as solvent recovery equipment and other mechanical equipment, separation of azeotropic mixture, ethanol Recycling and food industry and so on. The mechanism by which the two companies jointly developed the ceramic membrane separation function (taking the moisture in the air as an example) as an example
