【摘要】 <正> 关于中空纤维反渗透膜的研制,国外已进入商品化生产阶段,并广泛应用于电子、电力、化工、医药、食品以及苦咸水和海水的淡化.在国内,天津纺织工学院、大连化学物理研究所对以DP-1和9021为原料的中空纤维反渗透膜已于1979年和1981年先后完成实验室阶段的研制。至于以CTA为原料的中空纤维膜的研制,国內尚未见有报道。我们以国产三醋酸纤维素(CTA)为原料,采用环丁砜等为增塑剂的半熔融纺丝法更多还原

【Abstract】 This paper describs the preparation of CTA hollow fibers RO membranes and finds out the optimum condition for production membranes through fixed the compositon of spinning mixture, in the meanwhile, changed the condition of spinning process.When the feed water was 3000 ppm NaCl solution, at pressure 15 kg/cm~2, 25℃, as a result, the flux of the membranes was 0.5 ml/cm~2·hr, the salt rejection was about 85％.更多还原
