摘要
PURPOSE: An ultrafiltration membrane and a manufacturing method thereof are provided to improve permeability and mechanical strength, and to restrict loss of mechanical strength by forming an asymmetric surface layer.;CONSTITUTION: An ultrafiltration membrane includes an asymmetric surface layer which wherein a pore size is increased according to location within a membrane and a porous layer formed to a spherical particle type on the bottom of the surface layer. The porous layer is formed to a spherical particle type of 0.1~10 μm. The tensile strength of the ultrafiltration membrane is 37~45 N/m^2.;COPYRIGHT KIPO 2010
