The film coating machine can achieve effective and accurate coating in the application of nitrocellulose membrane, and prepare high-quality nitrocellulose film.
Membrane method
The film-making method generally includes the following steps:
Preparation materials: Mix nitrocellulose and solvent evenly to obtain a homogeneous nitrocellulose solution.
Adjust the coating head: select the appropriate coating head according to the needs, adjust the angle of the coating head, coating speed and other parameters.
Coating: The nitrocellulose solution is coated onto the substrate. During the coating process, the coating head should be kept horizontal, and the coating speed should be properly controlled to ensure uniform coating.
Drying: Place the coated substrate at an appropriate temperature to dry.
Nitrification degree test: Nitrification degree test is carried out on the dried nitrocellulose film to evaluate its performance.
The coating machine can adjust the thickness and uniformity of the film by controlling the coating speed and angle of the coating head, so as to prepare nitrocellulose films that meet different needs. The preparation of nitrocellulose film by a Film Applicator can obtain high-quality, high-reproducibility samples, and can improve production efficiency and reduce costs.
