Double-edged preparer

The double-blade preparator cuts samples with parallel upper and lower blades to form thin films of standard thickness. It is used for preparing films of coatings, inks, and other samples, and works in conjunction with a thickness gauge to detect coating uniformity. During operation, the blade spacing is adjusted to control the film thickness, making it suitable for laboratory quality control and product development.
Selection
When selecting, consider matching the sample viscosity with the blade gap width—choose wider gaps for high viscosity. Determine the preparation area according to testing standards, with the 100μm specification commonly used for routine inspections. Metal blades are more durable than plastic ones, and those with adjustment mechanisms facilitate better thickness control. Pay attention to the flatness of the substrate and the parallelism of the blade, and clean regularly to prevent residue buildup from affecting results.

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.
