    • Green glass content of mixed color glass cullet is selectively decolorized by using copper oxide and is used as an input component in a conventional glass production process. To determine how much copper oxide to add, the weight percent of green glass in the provided glass cullet supply is determined and an effective amount of copper oxide to, at least partially, decolorize the green glass is determined wherein an effective amount is determined using a non-linear inverse prediction model between the weight percent of green glass or chromium and/or iron content and the copper oxide. The amount of copper oxide is thus non-linearly adjusted for increasing levels of green glass in the glass batch. To compensate for the darkening of the glass by the additional copper oxide, the redox of the glass may be made slightly less reducing as the amount of chrome and copper is increased.
    • 混合彩色玻璃碎玻璃的绿色玻璃含量通过使用氧化铜选择性脱色,并且在常规玻璃制造方法中用作输入组分。 为了确定添加多少氧化铜,确定所提供的玻璃碎片供应中的绿色玻璃的重量百分比,并且确定至少部分地使绿色玻璃脱色的有效量的氧化铜,其中使用 绿色玻璃或铬和/或铁含量的重量百分比与氧化铜之间的非线性反演预测模型。 因此,为了提高玻璃批次中的绿色玻璃的水平,氧化铜的量被非线性调节。 为了通过附加的氧化铜来补偿玻璃的变暗,随着铬和铜的量的增加,玻璃的氧化还原可以略微减少。
