| Abstract: |
| In order to improve the quality of metal cans film, the effect of different roller coating process parameters on the performance of external coating of metal cans was studied. The influences of roller coating process parameters on coating properties were discussed， including the viscosity of coatings, the spacing between feeding roller and coating roller, the spindle speed and roller speed (tip speed ratio), and the optimal ranges of roller coating process parameters were obtained. The experimental results showed that the process parameter of viscosity of coatings, feeding roller and coating roller spacing, spindle speed and roller speed (tip speed ratio) had influence on the film adhesion grade, hardness, heat resistance of the metal cans film. The good comprehensive performance film could be gain when the viscosity of coatings was 85 s, Feeding roller and coating roller spacing was -4 μm, spindle speed and roller speed (tip speed ratio) was 2∶1. |
