Abstract

본 발명 칼라브라운관 도포공정에서 회수된 형광체를 분산하는 분산공정과, 열 알카리로 세척하는 공정과, 수산화 칼슘 등으로 표면처리하는 공정과, 안료 부착공정 및 탈수 건조 공정을 포함하고, 상기 안료 부착공정시 안료에 분산제를 혼입시켜 행함을 특징으로 하는 칼라브라운관의 형광면 도포용 형광체 처리방법로 되어 있으며, 상기 분산제로서 플루로닉 또는 타몰을 정미 형광체 대비 0.002∼0.05 중량% 사용하는 것으로 되어 있다. 또, 본 발명은 회수된 형광체 처리시 사용되는 안료의 조합시 분산제를 혼입시켜 조합 안료 조합방법을 제공하고 있으며, 상기 분산제로서 트윈을 정비 형광체 대비 0. 005∼0. 05중량% 사용하는 것으로 되어 있다. 이러한 본 발명과 같은 방법으로 안료를 조합하고 안료를 부착시킬 경우에는 신품 형광체에 가까운 특성을 가진 재가공 형광체를 생산할 수 있으며, 작업시 반응용기의 오염을 줄이고 안료의 부산성을 향상시키며, 작업시간을 단축시킬 수 있는 이점이 있다.The pigment adhesion process includes the dispersion process of dispersing the fluorescent substance recovered by the color-brown tube application process of this invention, the process of washing with thermal alkali, the surface treatment with calcium hydroxide, etc., the pigment adhesion process, and the dehydration drying process. It is a phosphor treatment method for coating the fluorescent surface of a color-brown tube characterized by mixing a dispersing agent into a pigment. In addition, the present invention provides a method for combining pigments by incorporating a dispersant in the combination of the pigments used in the treatment of the recovered phosphor, and Tween is used as the dispersant in the range of 0.05 to 0. 0. It is supposed to use 05% by weight. When the pigments are combined and attached to the pigments in the same manner as in the present invention, it is possible to produce reprocessed phosphors having characteristics close to new phosphors, to reduce contamination of the reaction vessel during operation, to improve the by-products of the pigments, and to improve the working time. There is an advantage that can be shortened.
