  • 현대사회에서 디스플레이 디바이스는 인류의 문명을 주도해 온 큰 산업기술의 하나이다. 20세기의 대부분에서는 브라운관이 그 기술의 한가운데 서 있었으나 1990년대 이후에는 평판 디스플레이가 그 기술 흐름을 주도해 나가기 시작했다.(중략)

  • Through alkaline hydrothermal activation processes, Na-A type zeolite was synthesized as a single phase withfunnel-glass waste from a television tube factory. The autoclaving was performed in a closed teflon vessel in therange of 80~95"C. The silica-rich solution as a starting material was hydrothermally synthesized with quartz in INNaOH by heating 350"C under the pressure of 1,500 atm. NaA102 was made from NaOH and Al(OH)3 by heating95"c for 2~3 hours and the molar ratios of it were Na20/A1203=1.4 and H20Ha20=8. The equi-dimensional Atype zeolite (1 ~2 U) was formed by the simple mixing of'the silica-rich solution, glass waste and NaA102 for I~3hours-heating at 80"C. The characterization of the reaction product shows Na-A as a single phase. The synthesizedzeolite has cube-dodecahedral form and Ca2+ ion exchange capacity of the Na-A was in the range of 215~220mequivalent/100 g.20mequivalent/100 g.

  • OA화시대의 도래로 인해 OA 기기가 보다 많이 도입되는 경향에 있다. 이러한 경향과 함께 CRT작업에 종사하는 작업자는 호조건하에서의 작업이 기대되고 있다. SRT(브라운관)작업은 눈의 피로의 원인이 되는 요소가 여러 가지 있으나 그 전부를 조명으로 해결할 수는 없으며 보다 피로가 적은 쾌적한 조명환경을 얻기위한 방법에 대해 생각해 보기로 한다.

Effect of Replacing Fine Aggregate by Cathode-Ray Tube(CRT) Waste Glass on Gamma-ray Shielding Properties of Cement Mortar Specimen (폐 브라운관(CRT) 유리의 잔골재 대체가 모르타르 시험체의 감마선 차폐에 미치는 영향)

  • In this study, the microstructure and gamma-ray shielding efficiency of CRT glass mortar specimen were evaluated with replacement ratio and material properties. The results show that as the replacement ratio of CRT waste glass increases, the volume of pores with diameters below 50 nm and above 400 nm is increased. Also, the half-value layer of CRT glass mortar decreased with the increasing of linear attenuation coefficient. In addition, compressive and flexural strength were reduced when CRT waste glass was replaced as the fine aggregate, but the mechanical performance of CRT mortar specimen could be obtained by substitution of the mineral admixture.

  • In recent years, various types of industrial wastes are rapidly increasing with the development of high-tech industries. Specially, high-density waste glass of CRT TV containing heavy metals are buried or disposed of due to reprocessing costs and environmental pollution problems. Thus, more basic research is needed to recycle waste such as CRT waste glass such. In this study, the fundamental properties and radiation shielding performance of mortar specimens substituted CRT waste glass as a fine aggregate were analyzed and their application to shielding materials was evaluated. According to the results, the bulk density of mortar specimen replaced with CRT waste glass was increased and the compressive strength and flexural strength were decreased. Meanwhile, the CRT waste glass substitute specimen containing a large amount of lead component showed a higher shielding performance than the general mortar specimen. Especially, the linear attenuation coefficient of CRT waste glass in $122KeV{\cdot}^{57}Co$ of the low energy field was 2.5 times higher than that of normal specimen.

  • TV 브라운관 유리와 컴퓨터 모니터용 유리를 생산하는 한국전기초자는 지난 99년 4월부터 최근까지 모터절전기 설치사업을 꾸준히 추진해왔다. 모터의 부하증감에 따른 전류와 전압의 위상차를 일치시킴으로써 모터의 회전수와 힘에 영향을 주지 않고도 정격주파수를 유지하면서 위상각을 제어하는 모터절전기 설치사업은 매달 전기료가 약 20억원에 이르는 이 공장에 $4.8\%$의 절전효과를 가져다주었다. 동력분야에서 이 정도의 절전효과가 발생하기는 쉽지 않은 일이기에 공장측은 앞으로도 지속적인 투자를 벌일 계획이다.

  • Theses days, the thickness of Brown tube becomes thinner since the display products are rapidly replaced by PDP, LCD etc. Accordingly, the shadow mask part also become flat. We propose the method of designing the surface with crown since the flat surface is fragile to vibration and shock.
