Key FeaturesExperimental Doctor Blade Automatic Small Testing Coating Machine
How to Use
1. Place the applicator on a perfectly flat test surface. Adjust the squeegee so that the required gap is twice the amount of wet film thickness required.
2. In front of the applicator, pour a small amount of test sample onto the end plate at a slow, even rate of about 1-2 cm per second.
3. Move the instrument over the surface until all of the liquid has been applied and or any remaining liquid has been removed from the end of the coating path.
4. The exact ratio of wet film thickness to any coater gap depends on the material used, the viscosity and texture of the liquid.
5. The actual wet film to be applied should be adjusted to your desired thickness using a thickness gauge to adjust the gap.
Frequently Asked Questions
How do I adjust the gap on the wet film applicator?
You should adjust the squeegee so that the gap size is set to twice the target wet film thickness. Use a thickness gauge to verify and fine-tune the gap for your specific application requirements.
Why must the applicator be used on a flat surface?
A perfectly flat test surface is essential to ensure uniform contact across the path, preventing uneven film distribution and guaranteeing accurate thickness measurements.
What is the recommended speed for pouring and coating?
The test sample should be poured onto the end plate and the instrument moved over the surface at a slow, even rate of approximately 1-2 cm per second.
Why does the wet film thickness not exactly match the coater gap?
The final wet film thickness depends on several physical factors of the sample liquid, including its viscosity, texture, and the specific material properties of the coating.
How do I ensure a clean coating path after application?
Continue moving the instrument smoothly across the surface until all liquid has been fully applied and any remaining excess liquid is cleared from the end of the coating path.
