Development of Bulk Lightweight Spherosilicate Material Technology Based on Sublimation of Expanded Polystyrene Granules

Abstract

The paper discusses the technology for producing bulk lightweight spherosilicate materials as an alternative to expanded vermiculite-based thermal insulation products. The technology is based on the idea of using granulated expanded polystyrene to create a core of silicate spheres coated with special liquid glass-based mixture and treated with carbon dioxide in the process of forming polystyrene-silicate mineralized granules to ensure quick hardening thereof. The paper also reviews a device and operation of the special equipment developed by the authors, such as a mixer for producing polystyrene-silicate mineralized granules and electric drum furnace for roasting spheres and subliming expanded polystyrene granules.
