本发明叙述了对于阴极射线管所使用的消气剂的组份,更具体的是蒸散型清气剂的组份。 在一般电子管的生产中,在管的内壁沉积着一层钡的消气剂薄膜,以便吸收管内在抽真空之后仍然残留的残余气体,并使管子在长期使用中保持所需的真空状态。当消气剂材料被蒸散而获得消气剂薄膜时,这些材料向着管子内壁蒸发,这时要求它的蒸气不沉积在管子中不希望被附着的部位上,例如电视显象管中的萤光屏和电子枪等部位。
The present invention describes the components of the getter used in the cathode ray tube, and more specifically the components of the evaporative-type getter. In conventional tube production, a barium getter film is deposited on the inner wall of the tube to absorb residual gas remaining in the tube after evacuation and to maintain the tube in the desired vacuum for long-term use. When the getter material is evaporated to obtain the getter film, the material evaporates toward the inner wall of the tube, requiring that its vapor not be deposited on the tube where it is not intended to be attached, such as a phosphor screen in a television picture tube and Guns and other parts.
