摘要
PURPOSE: A flow prevention device of low viscosity is provided to prevent the phenomenon of solution from flowing according to the lower end portion of the nozzle lip when coating the low viscosity solution by forming a stepped portion on the lower surface of the nozzle rib corresponding to the lower surface of the division nozzle shim of a slit die in an upward direction. CONSTITUTION: A flow prevention device of low viscosity comprises more than one partition member(222a,222b) and a pair of slit members. More than one division nozzle is equipped to the division nozzle shim(222). The division nozzle shim is provided within a first rib(220a) and a second rib provided by facing to each other. A pair of slit material is provided to the lower part of the first rib and the second rib, and covers more than one material. More than one lower surface of a division material, and a pair of lower surface slit material respectively have more than one projection unit formed in an upward direction. The slit die comprises the first rib, the second rib, the solution supplying unit, a chamber(226), and the division nozzle shim.
