提供DuraMem®和PuraMem® 有机溶剂纳滤(OSN)膜
我们现在可以提供DuraMem®和PuraMem®膜,这是我们化学耐药膜产品系列的有价值的补充。 由Evonik制造的Duramem®和Puramem®聚合物膜是有机溶剂纳滤(OSN)的市场***。
有机溶剂纳滤,即通过半透膜分离溶解在有机溶剂中的分子,在过去十年中已经获得了很大的发展。 OSN与常规分离过程的优点包括较低的能量需求,节约昂贵的原料和系统稳健性。
DuraMem®在大多数极性和极性非质子溶剂(丙酮,四氢呋喃,二甲基甲酰胺,异丙醇,乙腈,*****,乙酸乙酯等)中具有长期稳定性,而PuraMem®系列在非极性烃类溶剂(甲苯,庚烷, 己烷,*****,甲基 - 异丁基酮,乙酸乙酯等)保持稳定。
技术规格
DuraMem®和PuraMem®系列都有平板格式以及螺旋缠绕元件。 有关这些膜及其应用的更多信息,请联系膜工艺专家:北京品超思瑞
DuraMem® and PuraMem® membranes are now available as a valuable addition to our Chemically Resistant Membranes product line. Duramem® and Puramem® polymeric membranes, made by Evonik, are market leaders for Organic Solvent Nanofiltration (OSN).
Organic Solvent Nanofiltration, i.e. separation of molecules dissolved in organic solvents through a semipermeable membrane, has gained great traction over the last decade. Advantages of OSN over conventional separation processes include lower energy requirements, conservation of expensive materials, and system robustness.
DuraMem® offers long term stability in most polar and polar aprotic solvents (acetone, tetrahydrofuran, dimethylformamide, isopropanol, acetonitrile, methylethylketone, ethyl acetate, and more), while PuraMem® series is stable in apolar hydrocarbon-type solvents (toluene, heptane, hexane, methylethylketone, methyl-isobutylketone, ethyl acetate, and more).
