Abstract
Der erfindungsgemäße flexible Schüttgutbehälter ( FIBC ) ,bestehend aus einem textilen Gewebe aus hochfesten Kunststoffäden oder -bändchen ,zeigt dem Benutzer aus UV-Strahlungseinwirkung resultierende Materialschädigungen und damit den Zeitpunkt seiner aus Sicherheitsaspekten angeratenen Ausmusterung an.Das Anzeigen des aktuellen Materialschädigungszustandes wird dadurch erreicht, daß die Fäden oder Bändchen des Behältergewebes mehrschichtig aufgebaut sind, wobei auf einer die Innenseite des Schüttgutbehälters bildenden Trägerschicht mindestens eine äußere Funktionsschicht aufgebracht ist, die durch UV-Strahlungseinwirkung mit der Zeit photochemisch abbaut, wodurch der Verbund zur Trägerschicht sukzessive verloren geht und letztendlich die Trägerschicht freigelegt wird.Sind die Einzelschichten der Gewebefäden oder -bändchen unterschiedlich eingefärbt,wird der Schädigungszustand in Form eines Farbumschlages" visualisiert. The flexible bulk goods container (FIBC) according to the invention, consisting of a textile fabric made of high-strength plastic threads or tapes, shows the user material damage resulting from exposure to UV radiation and thus the point in time at which it is advised to retire from safety aspects. The display of the current material damage condition is achieved in that the threads or tapes of the container fabric are constructed in multiple layers, at least one outer functional layer being applied to a carrier layer forming the inside of the bulk material container, which degrades photochemically over time due to the action of UV radiation, as a result of which the bond to the carrier layer is gradually lost and ultimately exposes the carrier layer If the individual layers of the fabric threads or tapes are colored differently, the state of damage is in the form of a Color change "visualized.
