Abstract

본 발명은 브라운관(1)의 펀넬(2)과 판넬(3)을 봉착하는 프리트 글라스의 처리방법에 관한 것으로, 종래의 액상의 프리트 글라스가 건조과정에서 탈락되어 상기 펀넬 네크부(6) 또는 전자총으로 떨어져 브라운관(1)의 기능을 열화시키는 문제점을 해소하기 위하여 브라운관(1)의 펀넬실부(5)에 가결정의 프리트 글라스(7)를 위치시킨 후 상기 프리트 글라스(7)위에 브라운관(1)의 판넬(3)을 위치시켜 그래도 상기 브라운관(1)을 소결로에 투입가열하여 봉착시킴으로써 상기 프리트 글라스(7)의 탈락에 의한 분진 우려가 해소되어 브라운관(1)의 내압 특성이 향상됨과 더불어 환경오염을 방지하는 효과가 있다.The present invention relates to a method for treating frit glass for sealing the funnel (2) and the panel (3) of the CRT (1), the conventional liquid frit glass is eliminated in the drying process, the funnel neck portion 6 or the electron gun In order to solve the problem of deteriorating the function of the cathode ray tube 1, the frit glass 7 of provisional crystals is placed on the funnel seal portion 5 of the cathode ray tube 1, and then By placing the panel 3 and sealing the brown tube 1 by heating it in a sintering furnace, the possibility of dust caused by falling off of the frit glass 7 is eliminated, and the pressure resistance characteristics of the brown tube 1 are improved and environmental pollution is caused. It is effective to prevent.
