Product Introduction 
The Continuous coating tester uses a comma blade coating method. A precision wedge adjustment mechanism sets the gap between the blade and the substrate, achieving precise control of wet film thickness. The process flow is: substrate unwinding (magnetic powder tension control) → slurry coating → automatic web guiding → rewinding. The adjustable slurry trough design requires only a small amount of coating material per experiment, with a wider application range. The PLC control system and 7-inch touchscreen allow parameter setting, process monitoring, and data management. Tension is freely adjustable, and the drying unit is customer-supplied. This equipment accurately simulates continuous coating processes in actual production, providing a reliable experimental platform for formulation development and process parameter optimization.

Main Technical Specifications

FAQ 
1. What substrates and coatings are suitable for the continuous coating tester?
It is suitable for flexible webs such as paper, films (PET, PP, etc.), aluminum foil, copper foil, non-woven fabrics, and various water-based, solvent-based coatings, adhesives, battery slurries, and functional coating materials. Specific applicability can be verified through rheological testing of the coating fluid.

2. What are the advantages and applications of comma blade coating?
The comma blade controls the gap between the blade and substrate via a precision wedge mechanism with an accuracy of 1 μm. It is ideal for uniform coating of medium to high-viscosity slurries with precise wet film thickness control, particularly suitable for laboratory coating of adhesive tapes, battery electrodes, and functional films.

3. Why is the drying unit customer-supplied?
The equipment is the coating unit main body. The drying unit must be configured according to the user's process requirements (e.g., hot air oven, infrared drying, UV curing). Customers can select suitable drying equipment to connect with the coater based on their own drying conditions and process needs.

4. How should the tension control be set?
Tension is freely adjustable from 1-80 N via the 7-inch touchscreen. Unwinding uses a magnetic powder tension controller, and rewinding uses automatic tension control. Appropriate tension should be set based on substrate material, thickness, and width to avoid stretching deformation or wrinkling.

5. How does the automatic web guiding function ensure neat rewinding?
The instrument is equipped with an automatic web guiding system at rewind, with a guiding error ≤2 mm and rewinding accuracy ±0.5 mm. A photoelectric sensor detects the substrate edge position in real time and automatically adjusts the rewinding position to ensure a neat roll edge.

6. Can the coating width be customized?
The standard effective maximum coating width is 650 mm and is adjustable. For wider or narrower coating width requirements, our company can customize the guide roller width and coating width according to customer needs.
