Doctor-Blade (or Wire-Bar) Coating
Such Syringe Pump can be used for adding a solvent at various
concentrations. By using multiple syringe pumps, you can add
an ingredient in a certain weight ratio to a mixed solution.
Similar to the Horizontal-dipping Process, the blended organic
solution is introduced into the space between the barrier and
the substrate by such pumps' capillary action. The Doctor-Blade
is transported horizontally at a given constant velocity, a thin
solution layer is then spread and formed evenly on the
substrate.
