Molten glass vacuum refining: O-I Glass PackagingRecent Research Landscape
Entrained gas bubbles and foam from submerged combustion melting create structural defects in glass containers, requiring specialized low-pressure refining to ensure optical clarity.
What technical problems is O-I Glass Packaging addressing in Molten glass vacuum refining?
Submerged combustion bubble entrapment
(16)evidences
Submerged combustion melting produces highly foamy molten glass with over 20% gas volume that must be eliminated to prevent structural defects in containers.
Residual gas volume measurement
(17)evidences
Small gas seeds and bubbles remain suspended in the molten glass stream due to insufficient buoyancy or ineffective chemical fining during high-speed production.
