Abstract:
PURPOSE: A manufacturing method of a foamed glass panel using coal refuse and a foamed glass panel manufactured by the method are provided to prevent environmental contamination due to coal tailing. CONSTITUTION: A manufacturing method of foamed glass panel using coal refuse comprises the following steps: forming a foaming agent which includes a glass raw material, diatomaceous earth, and part of coal tailing(S110); and heat-treating the mixture(S130). 50-100 weight percent of the coal tailing is contained in the foaming agent. The glass raw material is manufactured by using the coal tailing glass as a main component. The coal tailing glass comprises 5-70 weight% of coal tailing, 5-30 weight% of soda ash(sodium carbonate),5-20 weight% of calcium carbonate, 0-10 weight% of magnesium sulfate, 5-15 weight% of silica, and 10-80 weight% of glass frit. The coal tailing is coal-preparation refuse and the coal preparation refuse is general coal preparation pumice or shell coal preparation pumice.
