摘要:

采用X射线衍射法研究了两种分别以叶腊石为主要原料但不含石英砂和以高岭土与石英砂为主要原料的无碱玻璃配合料从室温到1 200 ℃的物化反应。采用差热-热重同步分析仪研究了这两种配合料从室温到1 400 ℃的能量消耗以及吸放热反应。结果表明:以叶腊石为主要原料的无碱玻璃配合料比以高岭土为主要原料的配合料在熔化过程中少消耗的能量为50 J/g;将配合料由固态转变成玻璃态,以及保持这种随机的不规则玻璃态所需的能量很高,约占总能耗的55%~56%。

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 1 400 ℃ 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.
