Release film coating process and key characteristics (3)-film supplier
The relationship between coating and drying: the drying process and the coating process are independent and interrelated: the nature of the coating affects the design and operation of the drying process; the coating speed and the thickness of the coating determine the drying length; during the drying process The coating has a leveling process, so whether a coating machine can accurately use the best coating and drying process in the design process and balance the relationship between the two will ultimately affect the comprehensive technical performance of the coating machine. Current drying method: far-infrared radiation drying, thermal conductivity, hot drum drying, double-sided floating drying, conventional convection hot air drying, cycle hot air impact drying, drying process stage: transition phase: the part where the film temperature rises at the beginning of the drying process, and the coated coating enters In the drying box, the temperature of the film surface gradually drops due to the vaporization and heat absorption of the solvent or water, and there is a leveling process. Constant-speed drying stage: Several parts with the same temperature and speed. Deceleration drying stage: The temperature-decreasing part is a company specializing in the production of PET films with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply PET Motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
