Adjustable Blade Coater

The adjustable blade Coater controls the coating thickness by adjusting the gap between the blade and the substrate, forming a uniform wet film through the blade coating action. It is used in laboratories to simulate coating processes, test the leveling, hiding power, and other properties of coatings, and is suitable for ink and paper surface treatment testing.
Selection
When selecting, consider the substrate thickness range and coating precision requirements, match the corrosion resistance of the blade material, check the repeat positioning stability of the adjustment mechanism, confirm that the coating width is compatible with the sample size, and balance cleaning convenience with accessory completeness.

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.
Derivation and Validation of the Quantitative Relationship between Wire Diameter and Wet Film Thickness in Wire Wound Coating Bars
This paper investigates the relationship between the wire diameter in a wire-wound rod coater and the wet film thickness. Theoretically, under ideal conditions, the wet film thickness is approximately half of the wire diameter.
Actual Coating Thickness Deviation of Stainless Steel Wire Rod Coaters at Different Slurry Solid Contents
This article analyzes the actual coating thickness deviation of stainless steel wire rod coaters under different slurry solid contents. The study finds that the solid content of the slurry affects its viscosity and flowability, leading to deviations in the actual coating thickness from the theoretical value.
Coating film preparation techniques: comparison between wire-wound applicators and wet film preparators
This article compares two commonly used tools in laboratory coating film preparation: the wire rod coater and the wet film applicator.
The laboratory coating machine easily coats various aqueous and oily slurries.
The laboratory film applicator is a precision instrument used to prepare uniform coatings on substrates, primarily operating on the principle of a blade or wire-wound rod. It allows adjustment of parameters such as speed and pressure to control coating 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.

This article primarily compares the technical differences between wire-wound and extrusion coating rods. Although they are interchangeable in most scenarios, there are subtle variations in liquid loading capacity due to their distinct groove principles.
