Abstract

"PROCESSO PARA FORMAR UMA MEMBRANA MICROPOROSA E MEMBRANA MICROPOROSA COM MúLTIPLAS ZONAS E SEM SUPORTE". é revelada uma membrana microporosa, contínua, sem suporte e com pelo menos duas zonas. A membrana microporosa, contínua, sem suporte e com pelo menos duas zonas pode incluir pelo menos duas zonas com tamanhos de poro diferentes, ou os tamanhos de poro podem ser aproximadamente os mesmos. Também são revelados aparelhos e processos para fabricar membrana microporosa, contínua, sem suporte e com pelo menos duas zonas. Um processo de representação revelado para formar uma membrana microporosa, de inversão de fase, com múltiplas zonas, sem suporte e contínua, possuindo pelo menos duas zonas, tal processo compreendendo os seguintes atos: posicionar operacionalmente pelo menos um aparelho de aplicação de dopagem possuindo pelo menos duas ranhuras para abastecimento de dopagem, em relação a uma superfície de revestimento continuamente em movimento; aplicar dopagens de polímero vindas de cada uma das ranhuras para abastecimento de dopagem sobre a superfície de revestimento continuamente em movimento, de modo a criar um revestimento de dopagem de polímero de múltiplas camadas sobre a superfície de revestimento; e submeter o revestimento de dopagem de múltiplas camadas ao contato com um ambiente de produção de inversão de fase, de modo a formar uma membrana microporosa de inversão de fase, com múltiplas zonas e úmida. Outros aparelhos e processos de representação também são revelados.
