Key FeaturesExperimental Doctor Blade Automatic Small Testing Coating Machine
Imported Servo Motor:
Ensures speed control and stable pressure for optimal coating effect.
Collaboration:
Developed in partnership with multinational enterprises and research institutions.
Coating Head Design:
Quick 90-degree opening for easy cleaning of the scraper after experiments.
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 set the initial gap on the film applicator?
Place the applicator on a completely flat test surface, then adjust the squeegee so that the gap is set to twice the size of the target wet film thickness.
What is the recommended speed for pouring the test sample?
You should pour a small amount of the liquid sample in front of the applicator at a slow and steady rate of approximately 1 to 2 cm per second.
When should I stop moving the applicator?
Continue moving the instrument across the surface until all the liquid is fully applied, or any excess liquid is cleared from the end of the coating path.
Why does the wet film thickness not match the coater gap exactly?
The exact ratio between the wet film thickness and the applicator's gap is not fixed; it depends heavily on the viscosity, texture, and specific characteristics of the liquid material being used.
How can I ensure the applied wet film meets my required thickness?
You should measure the actual applied wet film using a dedicated thickness gauge, and then adjust the applicator's gap accordingly to achieve your desired precision.
