Method for producing foamed glass using hydrolysis of waste glass

摘要

The present invention relates to a method for producing foamed glass using hydrolysis of waste glass, the method for producing foamed glass of the present invention comprises the steps of hydrolyzing the waste glass powder, the waste glass powder hydrated by the hydrolysis reaction Adding a small amount of blowing agent, sintering and foaming the hydrated waste glass powder to which the blowing agent is added, and gradually cooling the foamed foamed glass to complete the foamed glass. According to the method for producing foamed glass according to the present invention, waste glass of various diseases such as plate glass, transparent bottle glass, brown bottle glass, green bottle glass, medicine bottle, pesticide bottle, etc. is used without hydrolysis reaction of glass without separate pretreatment separation process. Therefore, by manufacturing a low-density foamed glass with increased insulation, inorganic wastes containing glass components, including waste glass such as plate glass and bottle glass, can be recycled as lightweight insulation materials for construction and chemical processes at low cost.
