Surface deposits such as oil, iron fines or other impurities discourage adhesion and consequently the functional layer applied to the metal surface is irregular and easily removable under mechanical pressure. As a result, this functional layer cannot adequately fulfil its purpose. In preparing for the surface refinement process, an ultra clean base strip or base part surface is essential.
CMI Chemline’s cleaning solutions ensure that the functional layer (coating, painting or others) adhere properly and thus are able to provide their best performance in service.
The modular multi-stage system means that lines can be built to customers’ specific line parameters and requirements.
For Strip Degreasing or Cleaning Lines, CMI Chemline’s multi-stage system combines alkaline spray cleaning, brush cleaning, electrolytic cleaning and a final rinse section including a brush machine and dryer. It is designed to remove almost 100% of surface contaminants before further processing. Vertical spray degreasing and vertical electrolytic degreasing allow for a long effective treatment time within a short facility length, offering space-saving cleaning sections or plants.
CMI Chemline uses low current density cleaning, guaranteeing the same excellent cleaning performance achieved with high current density, but with considerably lower energy consumption. The specific flow path of the cleaning agent through the vertical process tank avoids the formation of gas bubbles and minimises foam production. Our multi-stage cascade rinse and the continuous regulation and automation of the bath concentrations not only provide excellent flushing, but combine reduced waste water requirements and fresh water consumption. CMI Chemline degreasing lines also use a closed exhaust treatment system across the line for reduced emissions.
