Abstract
PARA EL TRATAMIENTO DE TIEMPO CORTO DE UNA COLADA DE PLASTICO CON UN MEDIO DE TRATAMIENTO LIQUIDO BAJO PRESION, SE DIVIDE LA COLADA DE PLASTICO EN CANTIDADES PARCIALES LIMITADAS, SE APLICAN EN CONTACTO LAS CANTIDADES PARCIALES INDIVIDUALES CON EL MEDIO DE TRATAMIENTO Y DENTRO DE UN TIEMPO DE TRATAMIENTO DE MENOS DE UN SEGUNDO, SIENDO REUNIFICADAS LAS DIFERENTES PARTES AL MENOS EN UNA OTRA CANTIDAD PARCIAL, A PARTIR DE LO CUAL SE SEPARA LA CANTIDAD DE MEZCLA GENERADA Y SE LIMPIAN CON OTRA CANTIDAD PARCIAL. EL PROCESO DE LA SEPARACION Y DE LA LIMPIEZA SE REPITE MULTIPLES VECES EN DISTANCIAS DE TIEMPO DE AL MENOS UN SEGUNDO HASTA LA FORMACION DE UNA MEZCLA INTIMA DE LA COLADA DE PLASTICO CON EL MEDIO DE TRATAMIENTO. CON ELLO SE RECUPERAN PLASTICOS DE TIPO TERMOPLASTICO CONSTITUIDOS ESPECIALMENTE DE FORMA REGULAR, POR EJEMPLO PLASTICOS IMIDA ALQUIL POLIMETACRIL, QUE SON TOLERABLE CON METACRILATO POLIMETIL.
