Les origines de DuBois dans l’industrie papetière remontent à plus de 60 ans dans le domaine du nettoyage des machines à papier. Nous continuons à développer de nouvelles technologies chaque année afin de demeurer l’un des principaux fournisseurs de technologies de nettoyage pour les machines à papier.

DuBois dispose d’une gamme complète de nettoyants pour installations de machine à papier et de nettoyants de surface pour les usines de papier.

System Cleaning Solutions

Effective paper machine boilouts and system cleaning are vital to minimizing downtime and defects. The products and procedures used in system cleaning are critical to success, which DuBois understands. Prior to conducting a system cleaning, your DuBois representative will inspect and survey the system to determine the nature and degree of any deposition to ensure the correct program, products, and concentrations are used to effectively address and remove the deposition.
DuBois Chemicals offers a range of advanced system cleaning solutions tailored to meet the needs of paper mills. Our offerings include the Bubble-Ups® process, uniquely developed by DuBois, which uses internal foam cleaning to address critical deposit control areas such as approach piping and headboxes, reducing chemical use and time compared to traditional boilouts. We also offer patented oxidizing cleaners for removing thick deposits and biofilm from coaters, paper machine, starch, and dye systems, all with a non-corrosive safety profile.

Machine Surface Cleaning Solutions

Maintaining clean surfaces of papermaking equipment is critical to operating a machine without defects and breaks. The wet end of a paper machine is prone to scale, biological slimes, process additives, and fiber buildup, while the dryer section can accumulate a buildup of grease, oils, and paper dust, creating flammability hazards. Coaters and size presses must also be clean to avoid sheet defects and breaks.
DuBois will work closely with your employees to ensure the proper procedures and training are established for safe and efficient foam/gel cleaning. We can even provide equipment tailored to your cleaning needs. Our cleaning technologies include gel-based solutions that provide extended contact time, making them more economical and effective than other methods. We also offer foaming cleaners designed to tackle difficult soils like greases and oils, with formulas that cling to surfaces for prolonged cleaning such as dryer sections, size presses, floors, and walkways.
