    • It is an object of the present invention to present a method for producing an electron tube capable of preventing agglomeration of particles contained in coating material to be coated on an shadow mask to form an electron beam reflecting film, that causes settling of the particles on a shadow mask or clogging of the coating system, and fluctuations of pressure for supplying the coating material to a spray nozzle, that cause unstable quantity by weight of the coating material discharged from the nozzle and excessive coating, thereby preventing deterioration of the quality of images. An electron beam reflecting film of high surface coverage can be formed for the electron tube with a small quantity by weight of the coating material containing bismuth oxide particles which have an average particle diameter D50 of 0.6 nullm or less and a particle size distribution with the particles having a diameter between D40 and D60 accounting for at least 20% by volume of the total particles. This method supplies the coating material by oscillations of a piezoelectric element to the spray nozzle, or scans the nozzle just by slanting the nozzle at varying angles while keeping a head between the surface of the coating material in a coating material storage section and the nozzle center.
    • 本发明的目的是提供一种电子管的制造方法,该电子管能够防止涂布在荫罩上的涂层材料中所含的颗粒的聚集,形成电子束反射膜,导致颗粒沉降在 荫罩或涂布系统的堵塞,以及用于将涂料供给到喷嘴的压力波动,其导致从喷嘴排出的涂料的重量不均匀和过度涂布,从而防止图像质量的劣化。 对于电子管,可以形成少量的含有平均粒径D50为0.6μm以下的氧化铋粒子的涂布材料和与该粒子的粒径分布的电子束的电子束反射膜 D40和D60之间的直径占总颗粒体积的至少20体积%。 该方法通过压电元件的振荡向喷嘴提供涂层材料,或者通过以不同的角度倾斜喷嘴来扫描喷嘴,同时在涂料存储部分中的涂料的表面与喷嘴中心之间保持头部 。
