Abstract

Fine particles of glass cullet (fines) arising during glass recycling cannot presently be recycled into glass manufacture due to the potential for bubble formation and foaming. Consolidation of glass fines into briquettes could enable their re-introduction into furnaces, reducing waste and glass melting energies. Properties of briquetted cullet fines and briquette melting behaviour in soda-lime-silica glass batches are presented. Morphology and density of glass fines and briquettes; and briquette mass and mechanical properties as functions of time after formation were analyzed. Compressive strength increases linearly with time after briquette formation. With slight batch modifications to maintain the same final glass composition, up to 15 wt % briquettes were successfully added to a representative container glass batch and melted. Results confirm that briquette batch additions can provide equivalent final glass composition, optical absorption characteristics and redox to briquette-free batches, supporting their industrial uptake.

废玻璃碎粒压块，用于节能玻璃制造

在玻璃回收过程中产生的玻璃碎粒(细粒)由于可能形成气泡和起泡，目前不能再回收到玻璃制造中。将玻璃细粒固化成压块可以使它们重新进入熔炉，减少浪费和玻璃熔化能量。介绍了球团碎粒的性质和在钠-石灰-硅玻璃中球团的熔化行为。玻璃微粒和压块的形态和密度;分析了成型后型煤的质量和力学性能随时间的变化规律。成型后抗压强度随时间线性增加。通过轻微的批次修改以保持相同的最终玻璃成分，将高达15 wt %的压块成功添加到具有代表性的容器玻璃批次中并熔化。结果证实，批量添加型煤可以提供与无型煤批次相同的最终玻璃成分、光学吸收特性和氧化还原，支持其工业应用。

期刊介绍： The Journal of the Society of Glass Technology was published between 1917 and 1959. There were four or six issues per year depending on economic circumstances of the Society and the country. Each issue contains Proceedings, Transactions, Abstracts, News and Reviews, and Advertisements, all thesesections were numbered separately. The bound volumes collected these pages into separate sections, dropping the adverts. There is a list of Council members and Officers of the Society and earlier volumes also had lists of personal and company members. JSGT was divided into Part A Glass Technology and Part B Physics and Chemistry of Glasses in 1960.
