Study of Recycling Processes of Mixed Waste Glass to Obtain Expanded Glass when Using Glycerol Blowing Agent

Abstract
Recycling features of mixed waste glass to obtain a promising heat-insulating material, expanded glass, are considered. The effective glycerol blowing agent was selected, compositions of initial batch mixtures and research methods were developed. The thermal destruction of the blowing agent during the expension of foam-glass mixtures was experimentally proven and analyzed. The effect of liquid glass in pore-forming mixtures on the thermal degradation of glycerol is described. Main stages of sintering, softening, and foaming of the foam-glass mixture were studied with photo accompaniment in comparison with the initial glass powder without additives. To confirm the experimental results, a theoretical calculation of the temperatures required to achieve the limits of glass viscosity was carried out.
