Film Sample Preparation Device

The film applicator uses a blade to evenly spread liquid samples on a substrate at a constant speed, forming a uniform wet film to simulate the film-forming process of coatings, inks, and other materials. Its function is to prepare standard-thickness coating film samples in the laboratory, which are used for performance tests such as the hiding power of coatings and the printability of inks.
Selection
Select the coating gap range based on the viscosity of the sample to be tested, determine the coating width according to the substrate size, and consider the corrosion resistance of the material. Match the accuracy level required by standard specifications, and select the model and specifications based on the film thickness requirements of conventional experiments.

The importance of maintaining a constant speed when using a wet film applicator for coating.
When using a wet film applicator, maintaining a constant speed during the scraping process is crucial for coating uniformity. The scraping speed directly affects the wet film thickness, and fluctuations in speed can lead to defects such as streaks and uneven thickness, compromising the repeatability and accuracy of experimental results.
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.
