Blade material, edge profile, thickness and stiffness all affect coating quality. Learn how to choose the right paper coating blade for your coating line.
In the earliest coating doctor blade coating machines, the blade was attached to the lower lip plate of the material reservoir, and pressure was applied by the
The vibration frequency of the coating machine is monitored and adjusted to improve the surface properties of the coated paper. The doctor blade coating
A PCB Pizotronics Model 309A accelerometer was used to coating doctor blade vibration. This accelerometer has a diameter of approximately 5.84 mm, a height of
The coating unit on a multi-wire paperboard machine consists of: a curved doctor blade on the first coater and a straight beveled coating blade (straight
Examining the coating blade model for paper coating reveals that the inclined surface of the blade can cover two large clusters of densely packed flocculates
Coating Blades Substrates Blade coating technology is suitable for substrates of various materials, such as paper, plastic, metal and glass. Nevertheless,
Regular Inspection Conduct regular inspections on coating blades, including checking the wear condition of the coating blade edge, the gap between the blade
Uneven Coating Uneven blade pressure, poor fluidity of coating liquid, severe blade wear and other factors prevent the coating liquid from being evenly
Coating Blades Pressure Appropriate blade pressure ensures close contact between the coating blade and the coated surface, efficiently removing excess coating
