Quadrilateral Coater

The quadrilateral Coater controls the coating thickness through an adjustable quadrilateral groove, evenly applying the liquid onto the substrate surface. It is used in laboratories to simulate the blade coating process and test the leveling and hiding power of coatings. It is suitable for the preparation and quality control of coatings on materials such as inks and paper.
Selection
Select the applicator size based on the substrate thickness; use wider gap models for high-viscosity coatings. Stainless steel offers corrosion resistance, while carbon steel is suitable for routine use. Verify scale accuracy and ensure flatness with a leveling plate. Consider ease of cleaning and storage protection requirements.

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.
