Abstract

본 발명은 칼라브라운관 제작시 현상공정에 회수되는 형광체에 포함되는 각종 이물질을 용이하게 제거하여 재사용할수 있도록 하며, 형광체 입자간에 발생되는 응집현상을 방지하여 형광막의 균일한 도포가 이루어지도록 하기 위한 것으로, 칼라브라운관 도포공정에서 제거되는 미노광부분의 형광체를 회수하여 순수에 분산하는 형광체 분산공정과, 상기 분산되는 형광체에 알카리를 주입하여 가열하는 열알카리 세척공정과, 상기 세척되는 형광체에 수산화칼슘으로 표면처리하는 표면처리공정과, 상기 표면처리되는 형광체에 안료를 부착하는 안료부착공정으로 구성됨을 특징으로 하는 회수형광체 재가공법이다.The present invention is to facilitate the removal and reuse of various foreign matter contained in the phosphor recovered in the development process during the production of color CRT, and to prevent the coagulation phenomenon generated between the phosphor particles to uniform coating of the fluorescent film, Phosphor dispersion step of recovering the fluorescent substance of the unexposed part removed in the color-brown tube coating process and dispersing it in pure water, thermal alkali washing process to inject alkali into the dispersed phosphor and heating it, and surface treatment with calcium hydroxide And a pigment attaching step of attaching a pigment to the phosphor to be surface-treated.
