Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE LATEX DE HALUROS DE VINILO Y VINILIDENO Y COPOLIMEROS DE LOS MISMOS. CONSISTENTE EN VERIFICAR LA REACCION EN UN MEDIO ACUOSO QUE CONTIENE EL MONOMERO O MONOMEROS QUE SE VAN A POLIMERIZAR, UN CATALIZADOR QUE RINDE RADICALES LIBRES Y AL MENOS UN EMULGENTE. LA POLIMERIZACION TIENE LUGAR A TEMPERATURA COMPRENDIDA ENTRE 30 Y 70C, Y CUANDO FINALIZA SE BOMBEA EL LATEX EN UN DEPOSITO A VACIO JUNTO CON VAPOR PARA RECUPERAR EL MONOMERO QUE NO HAYA REACCIONADO. EL LATEX SEPARADO PASA A UNA ZONA DE COAGULACION, FORMANDOSE UNA MEZCLA DE AGLOMERADOS FRIABLES DE PARTICULAS POLIMERICAS EN UN SUERO, SEPARANDOSE ESTE EN UNNA ZONA DE FILTRACION Y FORMANDOSE UNA PASTA HUMEDA DE POLIMERO, QUE DESPUES DE PRESIONARLA SE DESMENUZA, PASANDOSE LAS PARTICULAS Y AGLOMERADOS FRIABLES DEL POLIMERO A UNA ZONA DE SECADO DONDE SE MUELEN Y SECAN POR MEDIO DE AIRE CALIENTE A PRESION. LA TEMPERATURA DEL AIRE EN LA ZONA DE SECADO ESTA COMPRENDIDA ENTRE 50 Y 80C Y LA PRESION ENTRE 0,17 Y 5,44ATMOSFERAS.
