Le composé 146, souvent simplement désigné par "146", est un matériau historique dans le domaine du traitement de l'eau et de l'environnement. Ce polyuréthane hautement spécialisé, initialement développé par USFilter/Rex, est réputé pour sa remarquable résistance à l'usure, à l'abrasion et aux produits chimiques couramment rencontrés dans les applications industrielles difficiles. Bien que la formulation spécifique reste un secret commercial jalousement gardé, ses propriétés en ont fait le matériau de choix pour une large gamme de composants utilisés dans le traitement de l'eau et le traitement des eaux usées.
Une application clé du composé 146 réside dans les **inserts de dents de pignons**. Ces inserts, fabriqués à la fois par USFilter/Rex et Link-Belt, sont conçus pour remplacer les dents d'origine des pignons utilisés dans les systèmes de convoyage de matériaux abrasifs. Dans le traitement de l'eau, ces systèmes sont essentiels pour déplacer les solides tels que les boues, les graviers et autres déchets.
Voici pourquoi le composé 146 excelle dans ce rôle exigeant :
Durabilité exceptionnelle : Le polyuréthane haute performance présente une résistance à l'usure exceptionnelle, ce qui signifie que les inserts durent beaucoup plus longtemps que les dents traditionnelles en acier ou en fonte. Cela se traduit par une réduction des temps d'arrêt de maintenance et des coûts d'exploitation réduits.
Compatibilité chimique : Le composé 146 est imperméable aux produits chimiques corrosifs généralement présents dans les milieux des eaux usées, notamment les acides, les bases et les agents oxydants. Cela garantit que les inserts conservent leur intégrité et leur fonctionnalité même lorsqu'ils sont exposés à des conditions difficiles.
Réduction du bruit : Les propriétés élastomères du polyuréthane contribuent à un fonctionnement plus silencieux par rapport aux dents métalliques, réduisant ainsi la pollution sonore dans l'installation.
Maintenance réduite : La durabilité accrue et la résistance chimique des inserts en composé 146 réduisent le besoin de remplacements fréquents, contribuant à un fonctionnement plus efficace et rentable.
Avantages environnementaux : Grâce à la durée de vie plus longue des inserts en composé 146, la quantité de déchets générés par les dents usées est considérablement réduite. Cela s'aligne sur les objectifs de durabilité environnementale de nombreuses installations de traitement de l'eau.
Bien que le composé 146 soit une pierre angulaire du traitement de l'eau et de l'environnement depuis des décennies, son héritage continue d'évoluer. De nouvelles formulations sont en cours de développement, optimisant les propriétés pour des applications spécifiques et améliorant encore les performances. Alors que l'industrie continue de rechercher des solutions pour un traitement des eaux usées efficace et durable, le composé 146 reste un outil essentiel dans l'arsenal des ingénieurs et des opérateurs environnementaux.
