Prismatic Bird-Type Applicator

The prismatic bird-type applicator forms a fixed gap with the substrate through a triangular prism scraper, creating a uniform wet film during coating. It is used in laboratories to simulate the coating process and test properties such as paint leveling and hiding power. It is suitable for quality control in the ink and paint industries.
Selection
Select the blade gap according to the substrate thickness, determine the coating speed based on the sample viscosity, and choose the blade specification in accordance with the testing standards. Pay attention to the chemical compatibility between the blade material and the sample, and ensure the blade edge is free from defects. The ambient temperature and humidity must meet the testing 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.
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.
Application of Wire Bar Coater in the Preparation of Coating, Ink, and Printing Samples
A wire-wound rod coater is a laboratory tool used for preparing uniform wet film coatings on flat substrates, widely applied in the production of samples in the coatings, inks, and printing industries.
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.
The difference between a wire-wound rod coater and an extrusion coating rod
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.
