Abstract
PURPOSE: To manufacture a tubular permeable membrane having uniform physical properties in the direction of the tube length, by, in the manufacture of the tubular permeable membrane with ethylenevinyl alcohol copolymer, evaporating under a specific condition the solvent of the membrane-forming liq. having been applied through flow casting.
CONSTITUTION: Membrane-manufacturing liq., made by dissolving ethylenevinyl alcohol copolymer in a solvent composed of aliphatic alcohol such as methanol, glycerine and/or water, is applied on the inside surface of a suitable supporting tube such as glass tube, stainless steel tube. The solvent of membrane-manufacturing liq. having been flow-cast is evaporated and dried by blowing air from one end of the supporting tube at a linear velocity not lower than about 4m/sce. for 1W180sec., thereby forming a dense and thin skin layer on the membrane surface, so that a tubular permeable membrane of uniform physical properties is manufactured.
