STUDY OF TEMPERATURE REGIMES FOR THE FORMATION OF THE CELLULAR STRUCTURE OF FOAM GLASS

The aim of this work was to study the physicochemical processes occurring in the raw material mixture during thermal treatment and the kinetics of its foaming, with the ultimate goal of optimizing the technological parameters for foam glass production. The primary objective was to investigate the influence of temperature-time foaming regimes on the formation of the material's structure. The experimental charge consisted of highly dispersed float glass powder and anthracite. It was determined that the formation of an optimal porous structure is achieved at a temperature of 850 °C with a holding time of 20 minutes. The obtained samples exhibited a bulk density of 0.20 g/cm³, meeting the requirements for thermal insulation foam glass. The results obtained can be utilized for further improvement of foam glass production technology through the comprehensive utilization of cullet, slags, iron ore processing waste, and high-silica rocks.
