中国科学院沈阳分院和辽宁省石油化工局于1983年9月初在旅顺联合召开了聚砜酰胺(PSA)微孔滤膜技术鉴定会。与会专家和代表,通过听取技术报告,参观试验现场,实测产品性能,认真座谈讨论,一致通过了技术鉴定。聚砜酰胺微孔滤膜是中国科学院大连化学物理研究所和旅顺化工二厂经过两年多的联合攻关而取得的成果。它是以聚砜酰胺树脂为基材而制成的微孔过滤材料。过去,在制药、食品等工业上,一直沿用石棉滤板作滤材,效果虽然尚可,但近年来发现,该品能产生二次污 Shenyang Branch of Chinese Academy of Sciences and Liaoning Provincial Petrochemical Bureau in early September 1983 in Lushun jointly held the polysulfone amide (PSA) microporous membrane technology appraisal meeting. Experts and delegates attending the meeting passed the technical appraisal by listening to the technical report, visiting the test site, measuring the performance of the products, discussing and discussing them conscientiously. Polysulfone amide microporous membrane is the result of joint research conducted by Dalian Institute of Chemical Physics, Chinese Academy of Sciences and Lushun Chemical Plant after more than two years. It is made of polysulfone amide resin substrate for the porous filter material. In the past, pharmaceuticals, foodstuffs and other industries, has been using asbestos filter media, although the effect is acceptable, but in recent years found that the product can produce secondary pollution
