摘要
对硅酸盐平板玻璃进行恒温恒湿培养,采用原子吸收分光光度计法测定了玻璃的MgO和Na2O的析出量,采用荧光X-射线分光计法测定了玻璃风化后的表面成分。研究结果表明:该玻璃的总析碱性能随恒温恒湿处理的温度、湿度和时间的增加呈增加趋势,Na2O的析出量对温度敏感,MgO的析出对Na2O的析出有抑制效应。
By keeping the flat silicate glass at thermostat and humidistat,the amount of MgO and Na2O dissolved out from glass surface was determined by atomic absorption spectrometer, and the remained MgO and Na2O on the glass surface was measured by fluorescent X - ray spectrometer. Dissolubility of both MgO and Na2O increases with increasing temperature, relative humidity and soaking time, and the amount of soluble Na2O depends acutely on temperature, MgO depresses Na2O dissolution.
