Abstract

Se describen un procedimiento y un dispositivo para la producción en contínuo de espuma en bloque mediante espumación de una mezcla reactiva depoliuretano que contiene dióxido de carbono disuelto a presión, eliminándose la presión de la mezclareactiva en el recorrido a través de una zona de aliviode presión en forma de rendija, impidiéndose una obturación de la rendija mediante el movimiento relativo entre sí de las superficies delimitadoras de larendija.
