The disposal of cathode ray tube (CRT) generates large quantities of leaded glass waste. The encapsulation of glass from the funnel portion of CRT in cement clinker was investigated. Samples of cement raw material containing 0 (control), 0.1, 0.2, 0.3, 0.4, or 0.5 wt% of CRT funnel glass ground to less than 75 μm were heated to 1480 °C in an electric furnace for 1.5 h at a heating rate of 5 °C/min to produce cement clinker. The Pb encapsulation and chemical composition of the clinkers were analysed using X-ray techniques and atomic absorption spectroscopy (AAS). The maximum PbO encapsulation occurred in mixtures containing 0.1 wt% funnel glass.
阴极射线管（CRT）的处理会产生大量含铅玻璃废物。研究了将 CRT 漏斗部分的玻璃封装在水泥熟料中的情况。将含有 0（对照）、0.1、0.2、0.3、0.4 或 0.5wt% CRT 漏斗玻璃（研磨至小于 75μm）的水泥原料样品以 5°C/min 的升温速率加热至 1480°C 在电炉中加热 1.5 小时以生产水泥熟料。使用 X 射线技术和原子吸收光谱法（AAS）分析了 Pb 的封装和熟料的化学成分。在含有 0.1wt%漏斗玻璃的混合物中发生了最大量的 PbO 封装。
