一般的导电膜材料是由水分散的石墨粉、并加入若干粘接剂水玻璃后形成的悬浮液。将这种悬浮液涂敷在彩色显象管的内表面,烘烤干燥后,就得到石墨导电膜。涂复方法有刷涂、喷涂、浸涂等。刷涂法可把悬浮液涂在需要涂复的地方,这是刷涂的优点。但是刷涂的量不好控制,在极端情况下多余的量会集存流走,有时又刷涂不上(涂出的膜厚薄不均匀)。但是近年来,为使导电膜具有适当的电
The general conductive film material is made of water-dispersed graphite powder, and after adding a number of adhesive water glass formed suspension. This suspension is applied to the inner surface of a color picture tube, and baked to obtain a graphite conductive film. Coating method brush coating, spraying, dip coating and so on. Brush coating can be coated in the need to Tufu place, which is the advantage of brushing. However, the amount of brushing is poorly controlled, and in extreme cases the excess can accumulate and sometimes can not be brushed (unevenness of the applied film thickness). However, in recent years, the conductive film has suitable electric power
