UPGRADE OF PREPARATION OF BATCH MIXED WITH CULLET IN MELTING ELECTROVACUUM GLASS

摘要

The industrial practice of producing electrovacuum glass with periodical changes in glass compositions is considered. To satisfy changing the requirements of the contemporary TV and electronic industries, glass factories have to adapt to periodic production of electrovacuum glass with different light transmission and to continuously refine glass quality. The solution of these problems is related to certain specifics of preparing mixtures of batch with cullet. The production of TV screens with two different transmission coefficients generates three varieties of cullet: dark-colored, light-colored, and intermediate cullet formed during a transition from dark electrovacuum glass to light glass and vice versa. To produce glass with a constant preset transmission coefficient, it is necessary to store different cullet varieties in different hoppers and to ensure their precise proportioning with batch components.
