Three Minimum Wet Thickness Regions Of Slot Die Coating

Three minimum wet thickness regions of slot die coating ... An experimental study was carried out to determine the minimum wet thickness of slot die coating for low-viscosity solutions. There exist three distinct coating regions (I, II, and III), depending on the physical properties of the coating fluid, die geometry, and flow conditions. Prediction of the Minimum Wet Thickness of Slot Coating at ... numerical predictions. The minimum wet thickness limitation of the slot coating at certain web speeds, zero bead vacuum, and well-controlled coating gaps was investigated. The minimum wet thickness of the experimental coating has been well correlated with the computational results at each low capillary number, and the Fundamentals of Slot Coating Process - AIMCAL

It is possible to define the flowing behaviour through the slot-die by adding the coating liquid density, the working width, the gap between the slot-die and substrate speed with the equation . In this equation m describes the mass flow, U w the substrate velocity, B the coating width, h the wet film thickness and p the density. Comparison of vertical and horizontal slot die coatings ... In the present study, experiments are carried out to examine the difference between vertical and horizontal slot die coatings. The minimum wet thicknesses as well as the photographic images of coating bead under different coating conditions are presented for each case.
