从实验室批量生产过程到连续生产过程的放大可能导致膜形态和性能的意外变化。为了了解加工对醋酸纤维素过滤膜的结构和性能的影响，采用实验室规模的医生刀片和工业/生产规模的槽型压铸生产膜。由于铸造方法的不同，形貌也有所不同。然而，牛白蛋白血清和脂肪酶的过滤性能没有显著差异。(C) 2017 Wiley期刊公司
Scaling up from a laboratory batch process to a continuous manufacturing process can result in unexpected changes in membrane morphology and performance. To understand how processing effects the structure and performance of cellulose acetate filtration membranes, membranes were produced using laboratory-scale doctor blade and industrial/production-scale slot die casting. Differences in morphology were seen because of the different casting method. However, filtration performance using bovine albumin serum and lipase showed no significant differences.
