Wire-wound Rod Applicator

The wire-wound drawdown bar forms a quantitative wet film by rolling a metal rod wound with stainless steel wire on the substrate surface. The gap between the wires determines the coating thickness, which is used in laboratories to simulate the blade coating process, suitable for uniformity testing of inks and coatings, as well as paper coating preparation.
Selection
When selecting, consider the substrate flatness and width in relation to the length of the wire-wound rod. Choose the corresponding rod number based on the desired wet film thickness. For high-viscosity materials, select a rod with thicker wire specifications. Use stainless steel material for corrosive liquids. After the experiment, promptly clean the gaps between the wires with solvent to prevent clogging.

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.
