Usage method:
1. Place the coater on a completely flat test surface and adjust the clearance required by the scraper to twice the thickness of the required wet film.
2. In the front section of the coated knife, a small amount of test samples are poured between the end plates, and the instrument is moved on the surface at a slow and uniform speed of about 1-2 cm per second until the liquid has been fully coated and/or any remaining liquid has been removed from the end of the coated path.
3. The exact ratio of wet film thickness to any clearance of the coated knife depends on the material used, the viscosity and texture of the liquid, the pressure applied on the coated knife, the speed of the coated film and the geometric shape of the edge of the coated film.
4. The actual wet film should be measured by a wet film thickness gauge, and the gap should be adjusted until the required wet film thickness is reached.
Maintenance and maintenance:
1. Clean the instrument with appropriate solvents immediately after each use.
2. Both ends of the scraper move in the groove. The groove must be kept free of sample material at all times.
3. Differential heads may occasionally need to be repositioned. To correct wear or dislocation, components must be lowered or raised, which can be achieved by loosening (and removing) two hidden fixed screws on each differentiator.
