Study Findings from National Taipei University of Technology Broaden Understanding of Sustainable Energy (Thin-Film-Transistor Liquid-Crystal Display Waste Glass and Nano-SiO2 as Substitute Sources for Metakaolin-Based Geopolymer)
By a News Reporter-Staff News Editor at Energy Weekly News -- Researchers detail new data in Sustainable Energy. According to news reporting originating in Taipei, Taiwan, by VerticalNews journalists, research stated, "Thin-film-transistor liquid-crystal display (TFT-LCD) waste glass can be used as a raw material in the production of geopolymer because of its amorphous and also contains relatively large amounts of silicon and aluminum. The effects of nano-SiO2 (NS) addition levels (0%-3%) with 1% increments and the geopolymer replacement levels of TFT-LCD waste glass (0%-40%) with 10% increments were analyzed quantitatively."
The news reporters obtained a quote from the research from the National Taipei University of Technology, "The optimal geopolymer proportion was identified based on its mechanical characteristics and flexural strength. The geopolymer samples were also analyzed for changes in weight, and a thermogravimetric analyzer and 29 Si magic-angle spinning nuclear magnetic resonance to measure the short-range network ordering. The results of this study indicated that the TFT-LCD waste glass metakaolin (TWGM) geopolymer sample with 10% TFT-LCD waste glass and 1% NS exhibited greater strength and lower porosity than other samples. Understanding these characteristics is necessary to identify the mechanical strength, thermal stability, and the fundamental structure of a geopolymer system. Applying NS to a geopolymer enhances its compactness, improves its uniformity, and increases its strength."
According to the news reporters, the research concluded: "These results show that 10% TFT-LCD waste glass and 1% NS can be used as a partial substitute for metakaolin (MK) in geopolymer materials."
