METHOD FOR MANUFACTURING FOAMED GLASS BY USING WASTE GLASS AND FOAMED GLASS MANUFACTURED THEREBY

摘要

The present invention provides a method for manufacturing foamed glass having a low density and uniform pore distribution by using waste glass through a simple process, which does not require prior processes such as melting or hydrolyzing glass. The method for manufacturing the foamed glass according to one embodiment of the present invention, comprises the steps of: preparing the waste glass; adding a pore-forming agent and an oxygen supply agent for forming pores through a chemical reaction with the waste glass, and crushing the waste glass to form crushed glass; forming a glass molded product by molding the crushed glass; and forming the foamed glass comprising pores by heat-treating the glass molded product.
