Abstract

CERAS DE POLIETILENO MICRONIZADAS CON UN TAMAÑO DE PARTICULAS MEDIO ENTRE 1 A 30 MICRAS SON APROPIADAS COMO DISOLVENTES PARA EL DESPEGADO DE SUPERFICIES DE GRANULADOS DE ADHESION. LAS CERAS DE POLIETILENO MICRONIZADAS DESARROLLAN SU ACTIVIDAD SIEMPRE EN UNA CANTIDAD MENOR DE 0,01 A 2% EN PESO CON RESPECTO AL GRANULADO. PARTICULARMENTE Y PREFERENTEMENTE SE EMPLEAN CERAS DE POLIETILENO MICRONIZADAS QUE SE PRODUCEN A TRAVES DEL PULVERIZADO DE CERAS DE POLIETILENO FUNDIDAS CON GASES EN UNA TOBERA CON DOS MATERIAS.
