    Air Knife Coating Machine

    Overview Knowledge Standards Terms
    The air knife Coater adjusts the pressure of the flexible blade using compressed air to form a uniform coating on the substrate surface. It is used for the preparation of functional coatings on paper and films, achieving coatings of varying thickness through air pressure control.
    Selection
    When selecting, consider the substrate type and width, and match the coating speed range. Pay attention to the precision of air pressure adjustment and the blade material, and determine the equipment specifications based on the coating thickness requirements. Check airflow stability and maintenance convenience.

    How to Coat High-Viscosity Slurry – Parameter Setting Tips for Blade Coaters
    This article primarily discusses the parameter setting techniques for high-viscosity slurries on blade coaters. High-viscosity slurries exhibit characteristics such as shear thinning, so it is essential to leverage shear effects during coating to facilitate slurry spreading. After coating, the viscosity should recover quickly to prevent sagging.
    What are some cost-effective alternatives to roll-to-roll coaters for the early stages of flexible film R&D when the investment is too high?
    The investment in roll-to-roll coating machines is too high. What are some cost-effective alternatives for the early stages of flexible film research and development? Among blade coating, spin coating, and spray coating, which one would you choose?
