制作场致发光屏的主要工艺是将混在粘性电解质中的场致发光粉作成厚度均匀的薄层。目前采用的涂敷方法,如喷雾法,沉淀法,离心法等等,都无法保证涂层在重量,厚度,仔密性等方面有满意的重复性。近年来,电泳涂敷法得到了广泛的应用。其优点是:能涂敷形状复杂的工件,在涂层参数有良好的重复性前提下,有可能使生产过程自动化。 The main process of making electroluminescent screen is to make the electroluminescent powder mixed in the viscous electrolyte into a thin layer with uniform thickness. Currently used coating methods, such as spray method, precipitation method, centrifugation, etc., can not guarantee the coating weight, thickness, density and other aspects of satisfactory repeatability. In recent years, electrophoretic coating has been widely used. The advantage is that it is possible to apply complex shaped workpieces, possibly automating the production process with good repeatability of the coating parameters.
