Doctor Blading Overview
Doctor blading (also known as knife coating or blade coating) is a popular thin-film fabrication technique which involves either running a blade over the substrate or moving a substrate underneath the blade. There is a small gap that determines how much solution can get through. Here, the solution is effectively spread over the substrate.
The final thickness is a fraction of the gap between the substrate and the blade. The final thickness of the wet film will be influenced by the viscoelastic properties of the solution and the speed of coating.
Features of doctor blade/knife coating machine
1. Variable motor to precisely control the coating speed.
2. The cross-bar can be used to push the adjustable blade. There is no special requirement for the size of the adjustable scraper.
3. The waste collection box placed on the left edge of the vacuum chuck bed collects spare slurry to ensure the equipment itself and the surrounding area are clean.
4. The bottom intelligent vacuum heating chuck plate and digital display temperature control drying system can adapt to the development of science and technology of film formation under high temperature.
