Abstract

La présente invention concerne de manière générale les dispositifs d’absorption ou de rétention de liquide et plus particulièrement les dispositifs de rétention d’eau pour le contrôle des inondations ou lors de fuites d’eau importantes. Il a été découvert, de manière surprenante, qu’il est possible d’évaluer de manière très précise la quantité spécifique de polymère superabsorbant qu’il est nécessaire d’utiliser dans un article absorbant afin d’optimiser ses propriétés. L’invention est caractérisée en ce que le ratio (volume (en litres) d’absorption d’eau de ville (robinet) de la masse totale du polymère superabsorbant présent dans l’article absorbant) divisé par (volume final de l’article absorbant (en litre(s)) est compris entre 2,5 et 4,5, de préférence entre 3 et 4. Les articles absorbants selon l’invention permettent à l'humidité de pénétrer à l'intérieur de façon extrêmement rapide et, une fois gorgés d’eau, présentent une forme homogène idéale pour former des barrières de confinement, des murs, des digues parfaitement imperméables. Ils se présentent sous la forme de sacs légers, dans un état compact de petit volume, de sorte qu’ils puissent être facilement transportés, stockés et mis en place.
