以聚甲基丙烯酸树酯作为溶质的油溶性有机膜,由于它在提高屏幕发光亮度上有显著的成效,因此国内有些生产黑白显象管的工厂已用它取代了以硝化棉为溶质的有机膜,但是由于硝化棉的来源广泛,使用硝化棉有机膜的工艺较成熟,烤胶温度较低,特别是涂膜成品率一般还可达到85％以上,因此目前还有不少的厂仍使用硝化棉有机膜。为此我们想简单地谈谈硝化棉有机膜在黑白显象管中的使用情况。 Oil-soluble organic film with polymethacrylate as a solute, because of its significant effect in improving the brightness of the screen, so some of the domestic production of black and white CRT factory has replaced it with nitrocellulose as a solute organic However, due to the wide range of sources of nitrocellulose, the process of using nitrocellulose organic film is relatively mature, the baking temperature is low, especially the coating yield is generally more than 85%, so there are still many factories still using Nitrocellulose organic film. To this end, we would like to briefly talk about the use of nitrocellulose organic film in black and white picture tube.
