Análise de eficiência da membrana de vidro reciclado pelo processo de sinterização produzida no câmpus Ponta Grossa da UTFPR, em diferentes sistemas químicos

Abstract

The followingworkaims for demonstrating in which chemical systems the recycled glass membrane, made at Ponta Grossa campus of UTFPR, can be applied, motivated by a search of options of recycling of the glass, where it is useful in the laboratory. For that, a suitable filtration device that fits the membrane was developed as well as some modifications in a previous method were carried out, in order to observe possible improvements in its selectivity. After reproducing the procedures, it was necessary to develop a device capable of holding the membrane, which has 1.8 cm of diameter and 0.2 cm of thickness, by using easy-to-get, low cost materials, being easily reproducible at any place. After process adaptation, tests were performed to characterize the membranes, including their density, water absorption capability also flow rate tests for each membrane type, where the non sinterable phasesize was varied for selecting the size of formed pores. Once finished the tests, it was possible to perform a filtration using a coffee powder particulated system, showing it is possible to do a mixture separation process with efficiency.
