Caitu carried through on the part of accelerated aging test coating adhesion, can be found was a significant positive relationship between the surface roughness of the ivory color coated paper, coating adhesion and aging properties of the substrate, ie, the higher the roughness, T Bend value decreased less. This is because the roughness of the substrate surface, the greater the surface area, the bonding area between the coating and the substrate so that the greater the mechanical adhesion between them greater, and therefore an appropriate increase in the surface roughness of the substrate can improve the timeliness of color-coated coating adhesion properties. The new color-coated roll coater coating machine is the key equipment painted roll coating process Which is better, a higher yield using two sets of multi-color coating unit fine coater to shorten the replacement of paint and coating roller causing downtime time. Has developed a new coating machine: Features a double-coated fine coater head, that arrangement color coated paper quoted the head of the next two painted, coated with hydraulic drive roller replacement color coated paper, approximately two seconds to complete the color change, it small footprint; single slide coating machine, which eliminates the gap between the rolls of multiple errors piled higher than the traditional type slide coating machine precision coating, the coating thickness can implement the best control in large numbers saving coatings. Some roll coater also added Dr. knife used in the production of high quality color coated.
