Abstract

PROCEDIMIENTO PARA LA OBTENCION DE UNA PIEZA MOLDEADA FORMADA POR MATERIAL ESPUMADO DE POLIURETANO, ESPECIALMENTE UN ALMOHADON CON ZONAS DE DISTINTA DUREZA PARA ASIENTOS DE VEHICULOS. CONSISTE EN SOMETER EN UN MOLDE A UN PROCESO DE ESPUMACION UNA MEZCLA DE REACCION FORMADA POR UN COMPONENTE POLIOL QUE CONTIENE POLIETER CON UN MINIMO DE DOS GRUPOS HIDROXILO Y POR UN COMPONENTE POLIISOCIANATO QUE CONTIENE UNA MEZCLA DE DIFENILMETAN-DIISOCIANATOS Y POLIFENIL-POLIMETILEN-POLIISOCIANATOS OLIGOMEROS. DICHA MEZCLA DE REACCION SE PREPARA EN LOS CABEZALES MEZCLADORES, CON INDICES DIFERENTES SEGUN LAS DUREZAS DE COMPRESION DESEADAS EN CADA CASO Y LUEGO DESDE CADA CABEZAL SE ALIMENTAN LAS MEZCLAS PREPARADAS A LAS ZONAS RESPECTIVAS DEL CABEZAL.
