摘要
以生产线玻璃配方为研究对象,利用旋转式高温粘度计测定了E玻璃的高温粘度-温度曲线,研究了玻璃网络形成体(B2O3、SiO2、Al2O3)、网络中间体(TiO2、ZnO)和网络修饰体(CaO)对E玻璃高温粘度的影响。结果表明,在E玻璃中,B以[BO3]三角体的形式存在,Al3+以[AlO4]四面体形式,作为网络形成体存在;随B2O3含量的增加,熔体粘度逐渐降低;用0.5%SiO2替代0.5%B2O3,玻璃粘度有很大的上升;用0.5%Al2O3替代0.5%B2O3,玻璃粘度几乎没有变化;网络中间体TiO2、ZnO起降低熔体粘度的作用;网络修饰体CaO可以在一定程度上降低熔体粘度。
The high-temperature viscosity of E-glass was tested by rotating viscometer. The relationship between the high-temperature and its composition was researched. The changes of viscosity of glass melt with components （network former, intermediate former, and modified cation） were investigated. The results showed that B existed as [BO3] unit, and Al3＋ existed as [AlO4] unit. The viscosity decreased with the content of B2O3 increased. When 0.5%B2O3 was instead of 0.5%SiO2, the viscosity of melt increased to a great extent. But the viscosity was changeless with 0.5%Al2O3 instead of 0.5%B2O3. The intermediate formers （TiO2, ZnO） took effect of reducing the viscosity. The modified cation （CaO） could decrease the viscosity to a certain extent.
