Frame-Type Wet Film Coater

The box-type wet film applicator uses a metal frame to scrape the coating onto the substrate surface, forming a wet film layer of a fixed thickness. The gap depth determines the coating thickness, making it suitable for simulating coating processes and quality control in laboratories. It is applicable in scenarios such as ink adhesion testing and paint hiding power evaluation.
Selection
When selecting, consider the compatibility between substrate flatness and the applicator gap, with stainless steel material ensuring wear resistance. The coating thickness range must cover testing requirements, and maintain a uniform speed during operation. Clean residual coatings to maintain precision, and regularly calibrate the gap size.

Application of Two-Step Method with Pre-Coating and Fine-Coating in Eliminating Bubble Defects for Dual-Blade Coater
The dual-blade coater employs a two-step method of pre-coating and precision coating to eliminate bubble defects during the coating process. In the pre-coating stage, high shear force is applied to break the bubbles in the slurry, causing them to rupture and rise to the surface. The precision coating stage then precisely controls the coating thickness, removing any remaining bubbles to form a uniform wet film.
Key Points for Controlling Coating Longitudinal Uniformity with Manual Rod Coater Constant Speed Dragging Techniques
This article discusses how to control the longitudinal uniformity of the coating by dragging at a constant speed when using a manual wire rod coater. A constant-speed drag is crucial, as it directly determines the consistency of the wet film thickness.

The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
