众所周知,显像管玻璃中含有钡、锶、锆、镉等稀有金属,管颈和锥体部分由防止伦琴射线穿过的铅玻璃制成,如果将废旧显像管整体熔炼,则熔炼后的玻璃只能用来制造啤酒瓶。德国柏林高等技术学校专家发明一种筛选显像管玻璃装置。大功率激光器输出脉冲宽度为1微秒的激光,大小为0.5毫米的玻璃颗粒会在激光照射下瞬间汽化,变成为等离子体。分光计对等离子体辉光进行分析,查明玻璃中含有20多种
As we all know, the CRT glass contains barium, strontium, zirconium, cadmium and other rare metals, neck and cone parts by preventing the roentgen rays through the lead glass made, if the overall picture of the scrap tube melting, the smelting glass can only be used To make beer bottles. Berlin, Germany, higher technical school experts invented a screening kinescope glass device. High-power laser output laser pulse width of 1 microsecond, the size of 0.5 mm glass particles in the laser irradiation instantaneous evaporation, into a plasma. Spectrometer on the plasma glow analysis to identify the glass contains more than 20 kinds
