The slit coating method is that the anti-reflection film has a four-layer structure, namely substrate/hard layer/medium refractive index layer/high refractive index layer/low refractive index layer, and the slit coating method is preferred. Huang Shanghong once studied the cavity design of the slit coating nozzle, discussed the role of each component of the slit coating nozzle, and pointed out that the structure of the distribution cavity should make the pressure distribution reasonable, reduce the vortex, and fit the slit. It is necessary to set up the auxiliary cavity, so that the residence time of the material in the coating nozzle is the same, and other key factors in the design and manufacture of the slit coating nozzle. Micro-gravure coating system and slit coating system are precision coating systems involving elastic fluid dynamics. They need to be coated in an environment with high requirements for coating cleanliness. Any dust and impurities are important for coating. As a result, it is necessary to build new factories in accordance with ISO cleanliness standards and strictly implement cleanliness rules and regulations.
