Abstract

EN LA PRODUCCION DE ESPUMA POLIMERICA ALMACENADA EN BLOQUE, LOS REACTANTES DE ESPUMA SON SUMINISTRADOS A UN RECIPIENTE (1), LA MEZCLA DE ESPUMA DE REACCION PASA SOBRE UNA ABERTURA DE DESAGUE (2) DESDE EL RECIPIENTE Y A LO LARGO DE UNA PLACA DE DESCENSO INCLINADA HACIA ABAJO (3) HASTA UN TRANSPORTADOR (4), SE APLICAN DOS CAPAS DE REVESTIMIENTO SEPARADAS, PRINCIPALMENTE UNA PELICULA DE PLASTICO FLACCIDA INFERIOR (26) Y UNA HOJA DE PAPEL RELATIVAMENTE RIGIDA SUPERIOR (22), SOBRE LA MEZCLA DE ESPUMA DE REACCION CERCA DE LA ABERTURA DE DESAGUE (36) SE COLOCA UNA MANTA (40) PONDERADA POR UNAS PLACAS DE FLOTACION LIBRE (46) SOBRE LAS CAPAS DE REVESTIMIENTO EN LA ZONA DE EXPANSION DE LA ESPUMA PARA PRESIONAR LIGERAMENTE LA ESPUMA HACIA ABAJO. LA PELICULA DE PLASTICO SEPARADA Y LA HOJA DE PAPEL SE OBTIENEN A BASE DE DESLAMINAR UNA HOJA COMPUESTA (21) Y SON SUMINISTRADAS A LA SUPERFICIE DE ESPUMA EN UNA CONDICION SUSTANCIALMENTE SIN TENSION MEDIANTE UN MECANISMO DE DESPEGUE (22) QUE SEPARA LA HOJA COMPUESTA DE UN RODILLO DE SUMINISTRO. SE CONSIGUE UN MAYOR AHORRO COMO RESULTADO DE LAS CARACTERISTICAS MEJORADAS EN LA PARTE SUPERIOR DEL BLOQUE DE ESPUMA PRODUCIDO.
