METHOD FOR DECREASING BUBBLE LIFETIME ON A GLASS MELT SURFACE

A method of reducing bubble lifetime on the free surface of a volume of molten glass contained within or flowing through a vessel including a free volume above the free surface, thereby minimizing re-entrainment of the bubbles back into the volume of molten glass and reducing the occurrence of blist...

Zusammenfassung:A method of reducing bubble lifetime on the free surface of a volume of molten glass contained within or flowing through a vessel including a free volume above the free surface, thereby minimizing re-entrainment of the bubbles back into the volume of molten glass and reducing the occurrence of blisters in finished glass products. The method includes vaporizing a volatile material, entraining the vapor in a carrier gas to form an enrichment gas, and flowing the enrichment gas into the free volume to increase a concentration of the volatile material at the surface of the molten glass in the vessel. 一种减少在被包含在包括处于一定体积的熔融玻璃的自由表面上方的自由体积的容器内或从中流过的所述熔融玻璃的所述自由表面上的气泡寿命的方法,从而将气泡重新夹带回到所述熔融玻璃的所述体积中并减少在成品玻璃中发生起泡。所述方法包括蒸发挥发性物质,将蒸气夹带在载气中以形成富集气体,以及使所述富集气体流入所述自由体积以增加在所述容器中的所述熔融玻璃的所述表面处的所述挥发性物质的浓度。
