Title:
ポリマー膜における、およびポリマー膜に関連する改良
Document Type and Number:
Japanese Patent JP6831051
Kind Code:
B2
Abstract:
Disclosed is a method and apparatus for manufacturing a continuous web of polymeric membrane and for continuous downstream processing of said web. The apparatus 10 comprises: a casting station 20 for casting the continuous web M; a carrier 24 for carrying the web downstream; a membrane drier 30 downstream of the carrier, for drying the web; and a brushing station 40 downstream of the drier for brushing the web. Said drier is located immediately downstream of the carrier, and upstream of said brushing station. The apparatus 10 further includes an additional drying station 50 downstream of the brushing station 40. Brushing after drying retains more surfactant in the membrane which is useful for certain applications. In addition, initial drying eliminates virtually all solvents from the membrane, but leaves some non-solvent (e.g. water) within it, which in turn fixes the surfactant on the nitrocellulose fibers, which improves significantly the consistency and reproducibility of the membrane.
