Abstract

UN PROCESO DE POLIMERIZACION EN DONDE SE POLIMERIZAN MONOMEROS EN LIQUIDO DILUYENTE PARA PRODUCIR UN LIMO LIQUIDO QUE CONTIENE PARTICULAS DE POLIMEROS NORMALMENTE SOLIDOS, ABRIENDO PERIODICAMENTE UNA PUERTA DE TOMA DE PRODUCTO PARA PERMITIR LA CARGA DE LIMO LIQUIDO PARA QUE FLUYA DENTRO DE UNA ZONA CONFINADA Y ALARGADA QUE INCLUYE UNA LINEA CALENTADORA Y ENTONCES DENTRO DE UNA CAMARA DE FOGUEADO EN DONDE LOS COMPONENTES MAS LIGEROS SE SEPARAN DEL POLIMERO. EL PROCESO SE CARACTERIZA PARTICULARMENTE POR EL HECHO DE QUE LA ZONA ALARGADA CONFINADA ESTA CONSTRUIDA DE TAL MODO QUE EL TIEMPO DE FLUJO DE LA CARGA DE LIMO EN EL CALENTADOR ES IGUAL A AL MENOS ALREDEDOR DE 25 POR CIENTO DEL TIEMPO ENTRE EL TIEMPO DE CIERRE DE LA VALVULA DE ESTABLECIMIENTO Y LA SIGUIENTE OPERTURA DE LA VALVULA DE ESTABLECIMIENTO.
