Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA RECUPERACION DE SUSTANCIAS SINTETICAS COMPACTAS O POROSAS, LAS CUALES CONSISTEN TOTAL O PARCIALMENTE EN SUSTANCIAS SINTETICAS DE POLIURETANOS, POR LO QUE EL PROCEDIMIENTO SE CARACTERIZA PORQUE SE PREPARAN LAS MATERIAS SINTETICAS PARA UNA MEZCLA DE REACCION, CON UN INDICE DE HIDROXILO BAJO, QUE PUEDEN SER TRATADAS DE NUEVO DE LA FORMA HABITUAL EN NUEVOS PRODUCTOS TERMINALES, EN EL QUE LAS SUSTANCIAS SINTETICAS O BIEN, A) SON HIDRATADAS CON AGENTES HIDRATANTES ADECUADOS Y REDUCIDAS A UN GEL FLUIDO; O B) DISUELTAS Y/O DESCOMPUESTAS EN LOS HIDROXIPOLIMEROS ADECUADOS; Y C) EL INDICE HIDROXILO ES AJUSTADO AL VALOR DESEADO; D) DADO EL CASO, LA MEZCLA DE REACCION DE A), B) Y C) SE TRANSFORMA EN UN PREPOLIMERO DE URETANO, E) LAS MEZCLAS DE REACCION INDIVIDUALES DE A) HASTA C) SON PROCESADAS DE NUEVO EN UN PRODUCTO DE POLIURETANO, O CON AYUDA DE OTROS SISTEMAS ENDURECEDORES ADECUADOS, EN UNA SUSTANCIA SINTETICA. EL PRESENTE PROCEDIMIENTO PERMITE LA ADICION SELECCIONADA DE SUSTANCIAS SINTETICAS DISUELTAS O HIDRATADAS, LACAS, COLORANTES, RESINAS SINTETICAS, ELASTOMEROS, ASI COMO FIBRAS, LAMINAS DE METAL, SUSTANCIAS DE RELLENO, PIGMENTOS Y SUSTANCIAS AUXILIARES SIMILARES, COMO MATERIALES IGNIFUGOS, INHIBIDORES DE LA OXIDACION.
