Abstract
The present disclosure provides a liquid membrane conveying apparatus for preparing a porous membrane includes a transmission unit and a carrier unit. The carrier unit conveys a liquid membrane into a gelling solution by the entrainment of the transmission unit. The carrier unit includes a first carrier and a second carrier. The first carrier and the second carrier respectively contact with opposite edges of the liquid membrane along a conveying direction of the liquid membrane. The consistency of the pores on the two surfaces of the porous membrane is improved by using the liquid membrane conveying apparatus.
