Preparation of Feed Glass Materials for Producing a Foamed Borosilicate Glass Body from Waste LCD Panel

In this article, the foamed body of glass was manufactured from the waste borosilicate glass produced by wet pulverization process without additional pretreatment which can be used as a recycling method for waste LCD panel glass. Each 100 g of pulverized waste borosilicate glass with the size of less than 270 mesh were mixed with 0.3 weight fraction of carbon and 1.5 weight fraction of Na2CO3, Na2SO4 and CaCO3 and let them foamed for 20 minutes at 950. to manufacture the foamed body having the density of less than 0.3 g/cm(3). Additionally, adding SiO2 or H3BO3 to the mixture enabled the foamed body to have efficient formation of open pores which showed the possibility for producing the foamed body with new functionalities such as sound absorption.
