DEVICES AND METHODS FOR PREPARING A SLURRY AND COATING A SUBSTRATE WITH A SLURRY

NºPublicación: US2021135227A1 06/05/2021

Solicitante:

AQORA LTD [IE]

KR_20210006918_A

Resumen de: US2021135227A1

Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.
