Coating method employing ultrasonic waves. |
摘要 |
<p>A coating method by which the speed of coating can be improved remarkably regardless of the number of polar groups on the surface of a web and irrespective of the properties of material for the web. A coating solution flowing out of a liquid injector is applied to a web supported by a coating backup roller. A high frequency signal from a master oscillator is amplified and applied to a vibrator. Ultrasonic waves generated in the vibrator are guided by a horn to be radiated to the contact line between the coating solution and the web. With the invention it is possible to prevent a coating solution from being intermittently applied to a web, and it is also possible to increase the coating limit speed, for example, by 5 to 26%. In addition, lateral stair-stepped unevenness of thickness is not produced in the coating layer. <IMAGE></p> |
