AI Technical Summary
During the preparation of existing ultra-white glass, it is difficult to effectively remove air bubbles in the glass, resulting in the impact of the transparency and optical properties of the glass.
Ultra-white glass preparation methods using specific raw material ratios include quartz sand, sodium carbonate, boronite, magnesium sand, calcined alumina, potassium oxide, zinc oxide and phosphorus pentoxide, and through process steps such as kiln melting, vacuum debubbing, calendering molding and annealing treatment, combined with strontium chloride, calcium fluoride, barium nitrate and zirconium oxide as clarification decolorizers, synergistically to remove bubbles.
The high transparency and excellent optical properties of ultra-white glass are achieved, which improves the chemical stability, mechanical strength and compressive strength of the glass, while reducing the thermal expansion coefficient and melting temperature of the glass.
