Slot coating flows feasibility quality

Slot coating is commonly used in the manufacturing of adhesive and magnetic tapes, specialty papers, optical films and many other products. The coating liquid is pumped to a coating die in which an elongated chamber distributes it across the width of a narrow slot through which the flow rate per unit width at the slot exit is made uniform. 6 Bibliografia - DBD PUC RIO Capitulo 6.

The slot coating process in the production of polymer films has a wide range of applications. However, the process cannot be systemized. This study used the computational fluid dynamics software Polyflow to analyze the slot coating process and investigate the influence that the process parameters have... Effect of flow rate variation on the frequency response in… Slot coating, which is one of pre-metered coating processes, has been extensively studied for uniformly depositing coating liquids onto the web or substrate with a high speed [1,2]. As in other5. I. D. Gates, Slot coating flows: Feasibility, quality, PhD Thesis, Uni-versity of Minnesota (1999). Solution-Coating Technology for AMOLED | Fluid flow… Slot-Die Coating is the preferred commer-cial solution-coating technique for preparing thin uniform blanket layers, andFigure 4 (lower) shows a CFD simulation of a simple printing flow. The jet moves across a substrate with a surface-tension pattern that prevents overflow to neighboring print lanes.
