在降低废料和玻璃熔化能的情况下，研究了有代表性的容器玻璃批次在添加和不添加15wt%废碎细颗粒压块的情况下的熔化行为。采用差热分析-热重分析-质谱法研究了碳酸盐原料在熔融过程中的分解和反应。基于Ginstling‐Brounstein和Arrhenius方程，计算了两批典型容器玻璃在0%和15%型煤添加情况下的分解动力学。用X射线衍射仪（XRD）测定了各批次二氧化硅反应的高温相变和组分。型煤的添加通过降低碳酸盐分解活化能来加速分解反应和硅酸盐反应动力学。结果表明，在较低的温度下，添加蜂窝煤后，该批次中的硅砂会熔化。通过熔融后试样截面的宏观观察，研究了不同温度下的批量熔融过程和高温下玻璃液顶部的型煤熔化过程。本研究的结果支持了在容器玻璃批次中添加型煤在提高熔融速率和降低批次反应和分解温度方面的积极作用。
The melting behavior of representative container glass batch with and without the addition of 15wt% briquettes produced from waste cullet fine particles was investigated in the context of reducing both waste and glass melting energies. Carbonate raw material decomposition and reactions during melting were studied by DTA‐TGA‐MS. The decomposition kinetics of two batches, representing typical container glass batches with 0% and 15% briquette additions, were calculated by transformation degree based on the Ginstling‐Brounstein and Arrhenius equations. High temperature phase transitions and fractions of silica reaction in each batch were obtained from X‐ray diffractometry (XRD). The briquette additions accelerated the decomposition reactions and the silicate reaction kinetics by decreasing the activation energy for carbonate decomposition. Silica sand in the batch was shown to melt at lower temperatures with the addition of briquettes. Batch melting processes at different temperatures and briquette melting on top of the molten glass at high temperatures were investigated by macroscopic investigations of sample cross sections postmelting. The positive effects of briquette additions to container glass batches, in terms of increased melting rate and reduced batch reaction and decomposition temperatures, are supported by the results of this study.
