摘　　要：采用红外光谱法和动态热机械分析(DMA)法研究了羟基含量对全氧燃烧浮法玻璃结构弛豫的影响。在540℃以上发现了类似于金属玻璃的α弛豫现象。通过Arrhenius方程拟合得出,气氛比(H_2O与CO_2气体体积比)为2∶1的全氧燃烧浮法玻璃、气氛比为1∶1的全氧燃烧浮法玻璃和空气助燃浮法玻璃的激活能分别为4.74eV、5.82eV和7.50eV。由组态熵模型拟合的全氧燃烧浮法玻璃的组态熵值高于空气助燃浮法玻璃,且气氛比为2∶1的全氧燃烧浮法玻璃的组态熵值高于气氛比为1∶1的全氧燃烧浮法玻璃,说明全氧燃烧浮法玻璃的内部结构相比空气助燃浮法玻璃更加无序,而增加全氧燃烧熔窑内的水含量使全氧燃烧浮法玻璃的内部结构更无序,这也印证了羟基含量会对全氧燃烧浮法玻璃的结构弛豫造成一定的影响。The present work investigated the influence of hydroxyl content on structural relaxation in oxy-fuel combustion float glass by means of infrared spectroscopy and dynamic mechanical analysis（DMA）.Anα-relaxation similar to metallic glass at above540 ℃ was observed in the oxy-fuel combustion float glass.The apparent activation energy（obtained by fitting Arrhenius equation）values for oxy-fuel combustion float glass with 2∶1 atmosphere ratio（H2O/CO2 gas volume ratio）,oxy-fuel combustion float glass with 1∶1 atmosphere ratio and air-fuel combustion float glass are 4.74 eV,5.82 eV and 7.50 eV,respectively.Meanwhile,the configurational entropy（obtained by fitting the configurational entropy loss law）values of oxy-fuel combustion float glass are higher than that of air-fuel combustion float glass,in which atmosphere ratio of 2∶1 corresponds to a greater configurational entropy compared to atmosphere ratio of 1∶1.This connoted the more disordered internal structure of oxy-fuel combustion float glass compared to air-fuel combustion float glass,as well as the disordering effect of the water vapor in the furnace onto the internal structure of oxy-fuel combustion float glass,and thereby confirming that the hydroxyl content exerts a certain influence on structural relaxation of the oxy-fuel combustion float glass.
