Basic principles of laboratory coating machines

The laboratory Film Applicator is a device used to evenly coat a thin film on the surface of a substrate. Its working principle is based on the rheological properties and mechanical movement of the coating material. Film coating machines usually include coating heads, substrate transmission systems, coating control systems and other parts. The coating head makes the coating material evenly cover the surface of the substrate by controlling parameters such as nozzle spacing, coating speed and coating pressure.

Coating material selection

The choice of coating material is critical to the performance and application of fiber membranes. Commonly used coating materials include polymers, nanomaterials, functional additives, etc. Different coating materials have different properties and can be used to regulate the air permeability, mechanical strength, chemical stability, etc. of fiber membranes.
