| titleOfInvention | Phosphor processing method |
| abstract | (57) [Summary] [Objective] The object of the present invention is to simplify the process, and to treat the phosphor by removing impurities from the recovered phosphor to obtain a reprocessed phosphor with improved emission color purity and coatability. To provide a method. [Structure] In order to form a phosphor screen of a color picture tube, a method of treating a phosphor of an unexposed portion removed during development of a coated phosphor film uses a centrifuge for the phosphor of the unexposed portion. And collecting; and a step of dispersing the collected phosphor in pure water; a step of washing the phosphor dispersed in pure water with an alkaline aqueous solution; A step of draining; a step of washing this phosphor with pure water; a step of surface-treating the washed phosphor; a step of drying the surface-treated phosphor; a sieve of the dried phosphor with a mesh. Sizing to obtain a reworked phosphor. |
