Abstract

SE PROPORCIONA UN PROCESO PARA LA PREPARACION A TEMPERATURAS AMBIENTE DE UNA HOJA DE ESPUMA DE BASE DE POLIMERO EN LA QUE LA ESPUMA SE PRODUCE A PARTIR DE UN PRODUCTO DE REACCION CAPAZ DE CURARSE A TEMPERATURA AMBIENTE FORMADO POR LA REACCION DE UNA COMPOSICION REACTANTE QUE CONSTA DE UN PREPOLIMERO, TAL COMO UN POLIETER CORONADO DE ISOCIANATO, Y AGUA. EL PROCESO INCLUYE PROPORCIONAR UN SUBSTRATO CONTINUO (5); DEPOSITAR DICHO PRODUCTO DE REACCION SOBRE DICHO SUBSTRATO (5); COMPRIMIR DICHO PRODUCTO DE REACCION SOMETIENDO DICHO PRODUCTO A AL MENOS UNA COMPRESION DE UN GRADO PREDETERMINADO DESPUES DE QUE DICHO PRODUCTO DE REACCION SE HAYA CREMADO PERO ANTES DEL MOMENTO EN QUE DICHO PRODUCTO DE REACCION SE HAYA CURADO FINALMENTE; Y POR ULTIMO CURAR DICHO PRODUCTO DE REACCION. ADEMAS DEL PROCESO ANTERIOR TAMBIEN SE DESCRIBE UN APARATO PARA LA PRODUCCION DE LA ESPUMA MENCIONADA.
