膜法制备富氧空气,近年来取得迅速进展。富氧空气可用于气喘病及呼吸系统障碍的患者。但更主要用于富氧燃烧。目前,最广泛应用的富膜材料是硅橡胶。可以用嵌段、接技及交联等化学方法,改进硅橡胶的性能。讨论了聚(4-甲基戌烯-1),聚(乙烯基三甲基硅烷)、聚苯醚、聚富马酸二脂及聚(1-三甲基硅烷1-丙炔)等聚合物,作为富氧膜材料使用的可能性。最后评论了分离氧、氮的新的膜过程。
Production of oxygen-enriched air by membrane is a rapidly developingtechnology.There are two primary applications of oxygen-enriched air,firstfor home use by asthmatics and others who have lung diseases.However,the large market for oxygen-enriched air is
