Abstract
PROCEDIMIENTO ECOLOGICO DE FABRICACION DE ESPUMAS DE POLIURETANO. ESTE PROCEDIMIENTO PERMITE INDEPENDIZAR EN LA FABRICACION DE LA ESPUMA DE POLIURETANO EL EFECTO DE LAS UREAS DEL EFECTO DEL ANHIDRIDO CARBONICO (COSI2 SC), MEDIANTE EL CONTROL DE LA ATMOSFERA EN EL INTERIOR DEL RECINTO O CAMARA DONDE SE HA DE PRODUCIR LA REACCION, SOMETIENDOSE DICHO RECINTO EN TODO MOMENTO A LA VIGILANCIA DE SU PRESION Y POR TANTO DEL MANTENIMIENTO DE UNA PRESION SELECCIONADA, LO QUE PERMITE CONTROLAR LA SALIDA DEL COSI2 SC EN LA MEZCLA Y POR TANTO EL ESPUMADO DEL POLIURETANO.ECOLOGICAL PROCEDURE FOR THE MANUFACTURE OF POLYURETHANE FOAMS. THIS PROCEDURE ALLOWS TO INDEPENDIZE IN THE MANUFACTURE OF POLYURETHANE FOAM THE EFFECT OF THE UREAS OF THE EFFECT OF CARBONIC ANHYDRIDE (COSI2 SC), THROUGH THE CONTROL OF THE ATMOSPHERE INSIDE THE ENCLOSURE OR ROOM WHERE THE REACTION HAS TO BE PRODUCED ENCLOSURE AT ALL TIMES TO THE MONITORING OF ITS PRESSURE AND THEREFORE MAINTAINING A SELECTED PRESSURE, WHICH ALLOWS TO CONTROL THE EXIT OF THE COSI2 SC IN THE MIXTURE AND THEREFORE THE FOAMING OF THE POLYURETHANE.
