Bar Film Coating Machine

The rod Coater forms a uniform wet film by rolling a metal rod over the substrate to spread the coating. It is used in laboratories to simulate the coating process, testing properties such as leveling and hiding power of coatings, and is suitable for quality control in industries like inks and paper.
Selection
When selecting, consider the compatibility between the substrate type and size with the rod diameter. Choose metering rods of different wire diameters based on coating thickness requirements. Pay attention to the wear resistance and straightness of the rod material. The operation method should align with laboratory practices, and the accompanying substrate fixation device should ensure flatness.

Effect of Different Coating Speeds on Film Thickness Consistency in an Adjustable Film Applicator
This paper studies the influence of coating speed of an adjustable film applicator on film thickness uniformity. In the experiment, the coating blade gap was fixed at 100 μm, and a resin solution with a viscosity of 200 mPa·s was used to prepare films at five speeds ranging from 10 to 80 mm/s, followed by thickness measurements.
Discussion on the Relationship Between Speed Gradient and Film Thickness in Spin-Coating Film Formation
Spin coating is a common technique that uses centrifugal force to evenly spread droplets across a substrate to form a thin film. The film thickness is influenced by multiple factors, among which the gradient of spin speed and time is a key parameter. This study, based on fluid mechanics principles and experimental validation, analyzes the quantitative effect of the spin speed gradient on film thickness.
Friction coefficient meter adjusts the control of film slip agent addition.
This article introduces how to use a coefficient of friction meter to adjust the amount of slip agent added in film production.
Film Coating Machine vs. Spray Gun: The Impact of Different Coating Methods on Coating Performance Evaluation
This article compares two laboratory film preparation methods: the film applicator and the spray gun. The film applicator can produce coatings with uniform thickness and high reproducibility through blade coating, making it suitable for precise formulation studies. The spray gun simulates actual spraying, but the film thickness uniformity is poorer, and the surface may be rougher.
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.
Laboratory Coating Machine - A Scientific Tool for Preparing Precise Coatings
The laboratory film coater is a specialized device that prepares uniform coatings on substrates through mechanical means, primarily categorized into types such as blade coaters, wire bar coaters, and spin coaters. This equipment consists of precision components including a coating platform, a blade assembly, a transmission system, and a control system, allowing for precise control over coating thickness.
