Abstract

PROCEDIMIENTO PARA CORTAR POLIMEROS DE ETILENO EN ESTADO FUNDIDO. CONSISTE EN EXTRUIR UN POLIMERO TERMOPLASTICO FUNDIDO A TRAVES DE UNO O MAS ORIFICIOS, SUMERGIDOS EN AGUA, Y CORTAR LA HEBRA EXTRUIDA A MEDIDA QUE SE SOLIDIFICA, AÑADIENDO AL AGUA UN AGENTE TENSOACTIVO SELECCIONADO ENTRE EL GRUPO DE LOS NO IONICOS Y ANIONICOS EN PROPORCION 1/1.000 PPM, ELEVANDO LA TEMPERATURA EN 10GC DE LOS AGLOMERADOS DE POLIMERO DE ETILENO QUE TIENE UNA TEMPERATURA DE AGLOMERACION DE 50GC A 60GC Y PRESENTANDO DICHO AGENTE TENSOACTIVO UN BALANCE HIDROFILO/LIPOFILO (BHL) COMPRENDIDO ENTRE 10 Y 45, APROXIMADAMENTE.
