Abstract
본 발명은 컬러음극선관의 형광체 세정액 조성물에 관한 것으로, 스크린공정의 세정공정에서 초음파 진동을 이용하여 순수한 판넬내면의 스커트부에 미제거된 형광체를 제거시 순수의 세척력이 약하고 점도가 낮아 물이 튀겨 판넬의 형광면을 손상시키는 문제점을 해결하기 위하여, 순수한 적정량의 과산화수소와 소량의 암모니아수 및 0.2% PVA 용액을 첨가시켜 세척력을 강화시키고 점도를 높인 것이다.The present invention relates to a phosphor cleaning liquid composition of a color cathode ray tube, and when the phosphor is removed from the skirt portion of the inner panel of the pure panel using ultrasonic vibration in the cleaning process of the screen process, the cleaning power of the pure water is weak and the viscosity is low, so that water is splashed. In order to solve the problem of damaging the fluorescent surface of the panel, a pure appropriate amount of hydrogen peroxide, a small amount of ammonia and 0.2% PVA solution was added to enhance the cleaning power and increase the viscosity.
Description
본 발명은 컬러음극선관의 형광체 세정에 관한 것으로 보다 상세하게는, 판넬의 스커트(skirt)부의 형광체를 제거하는데 이용되는 형광체 세정액 조성물에 관한 것이다.The present invention relates to phosphor cleaning of a color cathode ray tube, and more particularly, to a phosphor cleaning liquid composition used to remove phosphors in a skirt portion of a panel.
컬러브라운과의 스크린공정에 있어서, R.G.B 형광체를 순차적으로 도포하고 나서 건조와 현상후 판넬내측면의 스커트부위에 미제거된 형광체를 세척하게 된다.In the screening process with color brown, R.G.B phosphors are applied in sequence, and then, after drying and developing, unremoved phosphors are washed on the skirt of the inner side of the panel.
이러한 미제거된 형광체의 세척은 초음파 진동을 이용하여 순수로 세척하게 된다.The washing of the unremoved phosphor is washed with pure water using ultrasonic vibration.
그러나 이러한 종래의 초음파 진동을 이용한 세척은 세척액으로 순수를 이용하므로 세척력이 낮아 형광체가 완전히 세척되지 않으며, 순수의 점성이 낮아 판넬 내면에 순수가 튀어들어가 판넬내면의 형광막을 손상시키는 경우가 종종 발생되었다.However, the conventional cleaning using ultrasonic vibration uses pure water as the cleaning liquid, and thus the phosphor is not completely washed because of low washing power, and the viscosity of the pure water is so low that the pure water splashes on the inner surface of the panel to damage the inner surface of the panel. .
본 발명은 이러한 종래 문제점을 감안하여 안출된 것으로, 판넬 스커트부의 미제거된 형광체를 초음파 진동으로 세정하되 형광체가 완전히 제거됨은 물론 판넬 내면에 튀어들지 않도록 충분한 점성을 갖는 컬러음극선관의 형광체 세정액 조성물의 제공을 그 기술적 과제로 한다.The present invention has been made in view of the above-mentioned conventional problems, and cleans the unremoved phosphor of the panel skirt portion by ultrasonic vibration, but the phosphor cleaning liquid composition of the color cathode ray tube having sufficient viscosity not only to be completely removed but also not to splash on the inner surface of the panel. Providing the technical problem.
상기한 기술적 과제를 해결하기 위하여 본 발명의 컬러음극선관의 형광체 세정액 조성물은 순수 60%, 과산화수소(H2O2) 30%, 암모니아수(NH4OH) 5% 그리고, 0.2% 폴리비닐알콜(PVA) 용액 5%로 이루어지는 것을 특징으로 한다.In order to solve the above technical problem, the phosphor cleaning liquid composition of the color cathode ray tube of the present invention is pure water 60%, hydrogen peroxide (H 2 O 2 ) 30%, ammonia water (NH 4 OH) 5% and 0.2% polyvinyl alcohol (PVA ) 5% solution.
이와 같이된 본 발명의 형광체 세정액 조성물은 종래와 같이 스크린공정에서 R.G.B 형광체 도포하고나서 건조 및 현상후 세정단계에서 초음파진동을 이용하여 판넬의 스커트부에 부착된 미제거 형광체를 세정하는 세정액으로 이용하게 된다.The phosphor cleaning liquid composition of the present invention as described above is applied to the RGB phosphor in the screening process as in the prior art, and then used as a cleaning liquid for cleaning the unremoved phosphor attached to the skirt portion of the panel using ultrasonic vibration in the cleaning and drying step after the development. do.
본 발명의 컬러음극선관의 형광체 세정액 조성물은 과산화수소(H2O2) 및 암모니아수(NH4OH)가 각각 적정량 첨가됨으로서 산화제로서의 기능하게 되어 세척력이 증가되어 순수만으로는 제거되지 않는 형광체도 동일한 조건하에서 완전하게 제거되게 된다.The phosphor cleaning liquid composition of the color cathode ray tube of the present invention functions as an oxidizing agent by adding an appropriate amount of hydrogen peroxide (H 2 O 2 ) and aqueous ammonia (NH 4 OH), respectively, so that the phosphor is not removed by pure water alone. Will be removed.
또한, 본 발명의 형광체 세정액조성물은 0.2%의 폴리비닐알콜(PVA)이 소량 첨가됨으로써 세정액조성물의 점도를 증가시키게 되는 것이다.In addition, the phosphor cleaning liquid composition of the present invention increases the viscosity of the cleaning liquid composition by adding a small amount of 0.2% polyvinyl alcohol (PVA).
따라서, 판넬의 스커트부위 세정시 세정액이 판넬내면의 형광체로 튀어들어가는 것이 방지된다.Therefore, the cleaning liquid is prevented from splashing into the phosphor on the inner surface of the panel when the skirt portion of the panel is cleaned.
이상에서 상세히 설명한 바와 같이 본 발명의 컬러음극선관의 형광체 세정액 조성물은 순수에 적정량의 과산화수소와 소량의 암모니아수를 첨가하여 형광체 세척력을 강화시키고, 소량의 폴리비닐알콜을 첨가하여 세정액의 점성을 증가시켜 튀김현상에 의해 판넬내면의 형광면 손상을 방지할 수 있는 장점을 갖는 유용한 발명이다.As described in detail above, the phosphor cleaning liquid composition of the color cathode ray tube of the present invention is added to the pure water by adding an appropriate amount of hydrogen peroxide and a small amount of ammonia water to enhance the cleaning power of the phosphor, and by adding a small amount of polyvinyl alcohol to increase the viscosity of the cleaning liquid to fry. It is a useful invention having the advantage of preventing damage to the fluorescent surface of the panel by the development.
본 발명은 형광체 도포후 건조 및 현상후 미제거된 형광체만을 완전히 제거할 수 있도록 한 형광체 세정액 조성물의 제공을 그 목적으로 한다.It is an object of the present invention to provide a phosphor cleaning liquid composition capable of completely removing only phosphors which have not been removed after drying and development after phosphor coating.
