Pourquoi certains sacs\/cartouches filtrantes n\u00e9cessitent-ils un traitement hydrofuge et ol\u00e9ofuge\u00a0?<\/b><\/p>\n
Nous recevons toujours des questions de la part des utilisateurs finaux des d\u00e9poussi\u00e9reurs, leur demandant pourquoi les sacs\/cartouches filtrantes doivent subir un traitement de finition hydrofuge et ol\u00e9ofuge.<\/span><\/p>\n La r\u00e9ponse est que, dans certaines conditions de filtration, ce traitement am\u00e9liorera les performances et prolongera la dur\u00e9e de vie des sacs\/cartouches filtrantes \u00e0 poussi\u00e8re.<\/span><\/p>\n De mani\u00e8re g\u00e9n\u00e9rale, nous consid\u00e9rons que la situation suivante facilite le d\u00e9sembuage\u00a0:<\/span><\/p>\n Lorsque le d\u00e9poussi\u00e9reur fonctionne \u00e0 une temp\u00e9rature inf\u00e9rieure au point de ros\u00e9e, et que les sacs\/cartouches filtrantes ne sont malheureusement pas hydrofuges et ol\u00e9ofuges, la poussi\u00e8re se m\u00e9lange \u00e0 la ros\u00e9e et se colle \u00e0 leur surface, ce qui les obstrue et augmente fortement la r\u00e9sistance dans les filtres. La capacit\u00e9 de filtration diminue alors et la consommation d’\u00e9nergie augmente sensiblement, ce qui r\u00e9duit consid\u00e9rablement la dur\u00e9e de vie des \u00e9l\u00e9ments filtrants.<\/span><\/p>\n De plus, d\u00e8s lors qu’il existe des mati\u00e8res acides dans l’air poussi\u00e9reux qui p\u00e9n\u00e8tre dans les b\u00e2timents de filtration (<\/span>bo\u00eetier de

sacs\/cartouches filtrantes ne sont pas hydrofuges et ol\u00e9ofuges, qui se bouchent tr\u00e8s facilement, \u00e9galement lorsque la ros\u00e9e acide est absorb\u00e9e par les mat\u00e9riaux filtrants, ce qui acc\u00e9l\u00e9rera la d\u00e9g\u00e9n\u00e9rescence des mat\u00e9riaux filtrants et r\u00e9duira la dur\u00e9e de vie des \u00e9l\u00e9ments
