Abstract

PROCEDIMIENTO PARA LA FABRICACION DE MEMBRANAS POROSAS DE FIBRAS HUECAS PARA LA SEPARACION DE PLASMAS. SE MEZCLA UN 10-30 POR 100 EN PESO DE UN POLIMERO FUSIBLE Y UN 70-90 POR 100 EN PESO DE UN LIQUIDO INERTE FRENTE AL POLIMERO, FORMANDO UN SISTEMA BINARIO QUE EN EL ESTADO DE AGREGACION LIQUIDO PRESENTA UN MARGEN DE MISCIBILIDAD COMPLETA Y UN INTERVALO DE AUSENCIA DE MISCIBILIDAD. SE EXTRUYE A TRAVES DE UNA BOQUILLA DE FIBRAS HUECAS A UNA TEMPERATURA SUPERIOR A LA DE SEPARACION DE COMPONENTES DE LA MEZCLA EN UN TUBO DE HILATURA. LA FIBRA, BAJO UNA ESCASA TENSION, SE RETIRA DESDE EL TUBO DE HILATURA, Y LA ESTRUCTURA FORMADA DE FIBRAS HUECAS, DESPUES DE LA CONSOLIDACION, SE LAVA CON UN DISOLVENTE.
