在电视显象管的生产中,为了使电子束轰击荧光屏而激发出来的光线能得到充分而有效的利用,需在荧光体表面蒸镀上平整的铝层,使光线向一方向反射,从而提高了显象管亮度。但由于荧光粉层表面凸凹不平,故蒸铝前应先涂复有机成膜材料,以形成一平整而光洁的表面,蒸铝后再将这层有机膜加热分解,这样所得到的铝层具有镜面状态,反射光线的效率高,
In the production of television picture tube, in order to make the electron beam bombard the fluorescent screen and the light can be fully and effectively utilized, the surface of the fluorescent material needs to be deposited on a flat aluminum layer to reflect the light in one direction to improve The picture tube brightness. However, since the surface of the phosphor layer is uneven, the organic film-forming material should be coated before the aluminum is evaporated to form a smooth and smooth surface. The aluminum layer is heated and decomposed after the aluminum is evaporated, so that the obtained aluminum layer has Mirror state, reflecting the high efficiency of light,
