摘　　要：浮法玻璃制造需要经历1500℃以上的高温热工过程,由此会造成大量的CO_(2)排放。要实现碳达峰、碳中和的国家发展战略,玻璃工业需要寻求新的低碳能源。以浮法玻璃为研究对象,探究了不同熔制气氛下浮法玻璃中羟基的含量,并对玻璃中羟基的形成原因进行了研究分析。结果表明,玻璃熔制过程中,气氛中H_(2)O含量的增加,玻璃中溶解羟基的量也随之增加。由于熔化气氛的变化,玻璃结构中的羟基含量由279 g/m^(3)增加到了581 g/m^(3)。玻璃中四桥氧结构在玻璃网络中的含量,会随着羟基含量的增加而降低。随着玻璃结构中三桥氧和二桥氧结构的含量增加,可导致玻璃熔体的黏度略微降低。The high-temperature thermal process above 150℃is required in float glass manufacturing,which can cause significant carbon emissions.To achieve the national development strategy of carbon peak and carbon neutrality,the glass industry needs to seek new low-carbon energy sources.Taking float glass as the research object,the content of hydroxyl in float glass under different melting atmosphere was investigated,and the formation reason of hydroxyl in glass was analyzed.The results show that the amount of dissolved hydroxyl in glass increases with the increase of H_(2)O content in the simulated atmosphere during glass melting.The hydroxyl content in the glasses structure were increased from 279 g/m^(3)to 581 g/m^(3)by the changes of melting atmosphere.With the increasing of hydroxyl content in the glasses structure,the content of four bridge oxygen structure in[SiO4]in the glass network decreases.The increase in the content of three and two bridge oxygen structures in glass structures can lead to a slight decrease in the viscosity of the glass melt.
