First implementation of Valmet's OptiFlo headbox with Aqua layering technology
"Valmet's new OptiFlo headbox with Aqua layering technology opens us new possibilities to develop our process and product. We have already seen the potential of the technology on how strength properties can be improved. Unlike with conventional technologies, a rapid starch feeding response can be measured when starch is fed through Aqua layer; in both cases 15% compression strength (RCT) improvement is achieved, but needed amount of starch is almost 30% lower with Aqua technology. Even in chemically challenging process conditions, the technology enables great results," Jin Doo Kim, Vice President, Dong Il Paper.
"Dong Il Paper Group is a forerunner in adopting new technologies, and they have been actively involved in developing new solutions for the paper industry with us. We are delighted to see Dong Il Paper realize the benefits of the new Aqua layering technology as the first in the industry," Hannu T. Pietilä, Area President, Asia Pacific, says.
Information about OptiFlo headbox with new Aqua layering technology
Valmet's new OptiFlo headbox with innovative Aqua layering technology makes it possible to produce a two-layer sheet with very good layer coverage using only one headbox and forming unit. The Aqua layering technology is developed for the most challenging stratified solutions where layer purity is a key feature. It produces a perfect, disturbance free purely layered structure that boosts strength properties.
In containerboard grades, this type of layering provides further possibilities to adjust the quality and strength properties. It enables the use of different furnish qualities, cheaper raw materials and functional additives between layers while giving flexibility to develop improved end products.
