Scraping polymer solution on the silicone mold is a new application case of the NBCHAO experimental coating machine. The thickness of the silicone mold is about one centimeter, and there are grooves of the same size on the mold. The polymer solution needs to be used The wire Bar Coater is scraped onto the silicone mold to scrape out a uniform liquid film. The use of a small coating machine can save manpower, realize automatic coating, and ensure the smoothness of the coating film.
Since the thickness of the silicone mold is relatively large, and the structure is composed of grooves, the scraping process should be gradually added according to the actual situation, so that each grid can be evenly coated with the polymer solution.
The following is a specific experiment demonstration video. Note that the laboratory coater must maintain an appropriate scraping speed during the scraping process.
The following is a diagram of the experimental scraping process.
