Abstract
"PROCESSO PARA FORMAçãO DE MEMBRANA MICROPOROSA DE INVERSãO DE FASE DE MúLTIPLAS CAMADAS SEM SUPORTE E MEMBRANA MICROPOROSA OBTIDA". é feita a divulgação de uma membrana microporosa contínua de pelo menos duas camadas sem suporte. A membrana microporosa contínua de pelo menos duas camadas sem suporte pode incluir pelo menos duas camadas de tamanhos de poro de membrana diferentes ou os tamanhos de poro podem apresentar aproximadamente o mesmo tamanho de poro. Os equipamentos e processos para a fabricação de pelo menos uma membrana microporosa contínua de duas camadas sem suporte também são divulgados. Um processo representativo divulgado para formação de uma membrana microporosa de inversão de fase de camadas múltiplas, sem suporte, contínua, apresentando pelo menos duas camadas abrange os atos de: posicionamento operativo de pelo menos um mecanismo de aplicação de massa de enchimento, que possua pelo menos duas fendas para alimentação de massa de enchimento de polímero referente a uma superfície de revestimento em movimento contínuo; aplicação de massa de enchimento de polímero de cada uma das fendas de alimentação de massa de enchimento sobre a superfície de revestimento em movimento contínuo de forma a criar um revestimento de massa de enchimento de polímero de camada múltipla sobre a superfície de revestimento; submeter à camada múltipla de massa de enchimento a entrar em contato com um ambiente produtor de inversão de fase de forma a formar uma membrana microporosa de camada múltipla de inversão de fase úmida; e em seguida lavar e secar a membrana. Outros equipamentos e processos representativos também são divulgados.
