The film coating machine can realize the uniform coating of luminous materials in the application of luminous film, so as to improve the brightness and spectral performance of luminous film. Luminous film is a thin film material commonly used in nighttime security signs and decorative materials, and its preparation process usually includes multiple process steps such as coating, drying, printing and compounding.
Membrane method
Membrane production methods mainly include wet film production and dry film production. In the preparation process of luminous film, commonly used film-making methods include spin coating method, spray coating method, roller coating method and printing method.
Among them, the spin-coating method is a commonly used dry film-making method, and the conventional steps involved are as follows: dissolve the luminous material in an organic solvent, and then apply it on a rotating substrate, and uniformly coat the liquid film on the substrate by centrifugal force On the surface, it is finally converted into a solid film by drying.
Application meaning
The coating machine can realize the uniform coating of the luminous film by controlling parameters such as coating speed, pressure and coating method, thereby improving the brightness and spectral performance of the luminous film. In the application of luminous film, the use of film coating machine can reduce the waste and loss of luminous materials, improve production efficiency and save costs. In addition, the film coating machine can also realize different coating methods and coating thicknesses, so as to meet the needs of different application fields.
