发众所周知,电视显象管均有铝化屏,而铝化屏的质量在很大程度上是取决于铝膜的基底——有机膜的质量,因此有机膜涂复工艺十分重要。在所有的涂膜方法中,适于大工业生产的有两种:喷雾法和喷流浇注法,我们姑且都叫它们为喷涂法。喷雾法适用于屏面尺寸较大的玻壳,其优点是:涂膜均匀性好,一致性好,可以做到无废品,成品管的亮度高,本文仅就我们的生产情况,对这种涂膜方法作粗浅的介绍。
It is well-known that there are aluminum screens in TV picture tubes, and the quality of aluminum screens depends largely on the quality of organic film, which is the base of aluminum film. Therefore, the organic film coating process is very important. Among all the coating methods, two are suitable for large-scale industrial production: spray method and jet casting method, let’s call them spray method. Spray method is suitable for large glass screen size, its advantages are: coating uniformity, consistency, can be no waste, finished tube brightness is high, this article only on our production, for this Coating method for superficial introduction.
