Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE UNA ESPUMA DE RESINA TERMOPLASTICA EMPLEANDO UN MEDIO ACUOSO.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE TRATA UN COMPUESTO DE RESINA CON EL MEDIO ACUOSO PARA HACER QUE DICHO MEDIO ACUOSO SE ADHIERA AL COMPUESTO DE RESINA Y SEA RETENIDO POR EL MISMO; SEGUNDA, SE AMASA EN ESTADO FUNDIDO EL COMPUESTO DE RESINA, TRATADO CON EL MEDIO ACUOSO, BAJO UNA PRESION ELEVADA TAL QUE SE INHIBA LA EVAPORACION DEL MEDIO ACUOSO; Y POR ULTIMO, SE LIBERA LA COMPOSICION DE RESINA AMASADA DEL ESTADO DE PRESION A QUE HA SIDO SOMETIDA, PARA OBTENER LA ESPUMA CORRESPONDIENTE. DICHA RESINA ESTA FORMADA POR PARTICULAS AGLOMERADAS POROSAS, SELECCIONADAS ENTRE RESINAS OLEFINICAS, RESINAS DIENICAS, RESINAS VINILICAS, RESINAS ACRILICAS, RESINAS ESTIRENICAS, RESINAS POLIAMIDICAS Y RESINAS DE POLIESTER.
