The effect of preliminary two-stage mixing on the lumpiness of bialkaline glass mixture for electric insulating glass

Lump formation in a double-alkali glass batch for insulating glass during storage in the cold has been investigated. Technological modes of two-stage preliminary mixing of sand with water and alkali-containing components in the preparation of the charge are proposed. The effect of water temperature and pre-mixing modes on charge lump formation has been studied. Technological recommendations are given for optimizing the mode of preliminary two-stage mixing of the charge. Tab. 1, ill. 1, bibliography: 3 titles.
