Abstract

"MEMBRANA DE FILTRAGEM MICROPOROSA E MéTODO PARA FABRICAçãO DA MESMA". A fase de inversão de membranas microporosas incluindo no mínimo duas regiões providas com diferentes tamanhos de poros, está caracterizada por duas membranas de folhas serem colocadas uma de costas para outra, de modo que as zonas de poros qualificadas sejam posicionadas internamente dentro da estrutura. Membranas exemplares de acordo com a presente invenção prove uma excelente estabilidade térmica e características de retenção. Métodos para fabricação e uso das estruturas de membranas reveladas são também providas de acordo com a presente invenção.
