无碱玻璃配合料熔化过程中的物化反应和能量消耗——叶腊石与高岭土和石英砂组合之间的比较
Physicochemical Reactions and Energy Consumption of Alkali-Free Glass Batches During Melting ——Pyrophyllite Versus Kaolinite and Silica
摘要
Abstract
The batch-to-glass conversion process of alkali-free (E-glass) batches containing pyrophyllite without sand and kaolinite with sand was investigated. The physicochemical reactions occurred during the batch-to-glass conversion process from room temperature to 1 200 ℃ were analyzed using X-ray diffraction method. Energy consumption and energies associated with endothermic and exothermic reaction from room temperature to 1400 ℃ were determined by a simultaneous thermogravimetric-differential thermal analysis system. The results show that the energy consumed for E-glass made from pyrophyllite based batch is lower than that from the kaolinite based batch by 50 J/g. The energy involved in batch fusion into molten glass, plus keeping melt in form of highly random structure is very high, about 55％ to 56％ of the total energy consumed for the entire conversion process.关键词
