Uniformity Correction for Fluid Coating Head
发布日期 2008
Slot coating is a widely used commercial process for applying one or more thin layers to a substrate such as paper, fabric, film or other material. In many cases, a highly uniform thickness is required, where a coating head that has been corrected for use with a Newtonian fluid may not produce a uniform coating when used with non-Newtonian fluids.
With a multiphysics calculation involving the simultaneous solution of fluid dynamic and thermal diffusion equations within a fluid coating die, we have demonstrated the correction of a cross-web flow nonuniformity with a counterbalancing temperature nonuniformity.
