Kemira is introducing KemFlite, a new concept to reduce paper and board machine problems that are caused by deposits due to the agglomeration of hydrophobic particles. These particles typically originate from wood pitch, stickies or binders in coated broke and have previously been difficult to detect and control. Under certain conditions the particles agglomerate to a larger size and eventually deposit on paper machine wet-end surfaces, wires, felts and dryer cans.
KemFlite is designed to manage the hydrophobic substances, particularly their size, before they form deposits. The concept combines Kemira’s deep papermaking process know-how, with its broad deposit control product portfolio and powerful new analysis and monitoring tools.
These tools include Kemira Flyto, a unique laboratory analysis to measure the particle size, quantity and hydrophobicity in samples taken from key points in the process, and Kemira AutoFlite, a new on-line device that continuously provides similar information.
Following a complete mill survey by Kemira’s application experts, a tailor-made deposit control program can be implemented to manage the hydrophobic substances found in the mill process waters and eliminate machine deposition. The KemFlite concept has been proven in numerous mill cases where it has improved machine runnability and reduced defects like holes, spots, specks and hickeys in the final paper or board product.
“KemFlite is a concept that pools together a range of Kemira products and our process know-how in a consolidated package, directly addressing the problems customers have with deposit control on paper machines,” explains Chris Lewis, Regional Applications Manager, Paper.
The result for papermakers is smoother operation, decreased downtime, better cost efficiency, reduced chemical consumption and improved finished paper and board quality.
