coater

Principle and application

The equipment drives the slurry through the rotation of the coating roller, adjusts the slurry transfer amount by adjusting the blade gap, and transfers the slurry to the substrate by the rotation of the back roller or the coating roller, controls the thickness of the coating layer to meet the weight requirements according to the process requirements, at the same time, the solvent in the slurry laid on the substrate is removed by drying and heating, and the solid matter is well bonded to the substrate.
