Otimização das variáveis na produção de membrana de vidro reciclado pelo processo de sinterização com posterior caracterização

Abstract

This study aims the production and characterization of recycled glass membranes, followed by the analysis of the used variables and their efficiency. The membrane production is made from the compaction of glass powder and sodium chloride, followed by the sintering, which should happen at temperatures below the glass melting. The mix was pressed in three different pressures, generating samples that were sintered in an oven also in three different temperatures. To form the pores, the samples were boiled in water, removing the salt and creating empty spaces on the membranes. After the production, the characterization was made, observing better results on the membranes sintered at 700ºC and compacted at higher pressures.
