Arabius模型是针对六种商业玻璃的加工温度范围内的玻璃粘度开发的：低膨胀硼硅酸盐玻璃、E玻璃、玻璃纤维棉、电视面板玻璃、容器玻璃和浮法玻璃。局部模型（对于六种玻璃类型中的每一种）和全局模型（对于商业玻璃的组成区域，即，这六种玻璃类型合在一起）。该模型基于先前在900°C和1550°C之间的温度范围内用旋转轴粘度计获得的粘度数据;粘度从IPas变化到750 Pas。一阶模型被应用到相关的Arrhenius系数的15个组分的质量分数：SiO2，TiO 2，ZrO 2，Al 2 O3，Fe 2 O3，B2 O3，MgO，CaO，SrO，BaO，PbO，ZnO，Li 2 O，Na 2 O，和K2 O。全局模型的R2为0.98，六个局部模型的R2范围为0.97 ~ 0.99.建议将该模型用于含42 - 84质量% SiO2的玻璃，以估算1100°C-1550°C温度范围和5 - 400 Pas粘度范围内熔体的粘度或恒定粘度下的温度。
Arrhenius models were developed for glass viscosity within the processing temperature range for six types of commercial glasses: low-expansion-borosilicate glasses, E glasses, fiberglass wool, TV panel glasses, container glasses, and float glasses. Both local models (for each of the six glass types) and a global model (for the composition region of commercial glasses, i.e., the six glass types taken together) are presented. The models are based on viscosity data previously obtained with rotating spindle viscometers within the temperature range between 900°C and 1550°C; the viscosity varied from 1 Pas to 750 Pas. First-order models were applied to relate Arrhenius coefficients to the mass fractions of 15 components: SiO2, TiO2, ZrO2, Al2O3, Fe2O3, B2O3, MgO, CaO, SrO, BaO, PbO, ZnO, Li2O, Na2O, and K2O. The R 2 is 0.98 for the global model and ranges from 0.97 to 0.99 for the six local models. The models are recommended for glasses containing 42 to 84 mass% SiO2 to estimate viscosities or temperatures at a constant viscosity for melts within both the temperature range from 1100°C to 1550°C and viscosity range from 5 to 400 Pas.
