A coating machine plays an important role in the surface coating production process, catering to a variety of materials including films and paper. Its primary function is to meticulously apply a layer of adhesive, coating, or ink that possesses specific functional properties onto a substrate in roll form. All this is followed by a drying phase, ensuring the applied material sets properly, before the substrate is re-rolled for subsequent use.

Corona treater utilizes a high-voltage electric field to atomize the coating material into ultra-fine particles. This advanced dispersion technique facilitates a uniform and even application across the substrate's surface, improving adhesion strength. The result is a product surface that resists common issues such as glue leakage or the occurrence of uneven coating, ensuring a flawless finish.

• Characteristics of the Coating Material
  Different coatings have different properties, such as viscosity, specific gravity, surface tension, etc., all of which will affect the coating effect of the corona treatment machine.
• Processing Conditions
  The processing conditions affect the choice of corona treater, including the characteristics of the substrate material, coating speed, and thickness requirements.
• Experience and Testing
  Using experience and testing is also an important means of selecting the appropriate power for a corona treater. Generally, it is necessary to conduct trials and adjustments in production practice to determine the optimal power of the corona treater based on actual conditions.
