Paper has been around for centuries. Over the years, the various things we use it for have remained fairly constant, but the way we make it has changed dramatically.
Manufacturing paper in the 21st century is a hi-tech, large-scale process which involves sophisticated machinery and equally complex chemistry. Environmental considerations are also now very much to the fore, both in terms of promoting more sustainable forestry and making the actual production more eco-efficient.
AkzoNobel’s Pulp and Paper Chemicals business, Eka Chemicals, has been developing products with a superior ecological profile for many years. One of the latest is the Compozil Fx concept, which uses the latest Eka nanoparticle silica and polymer innovations. The key benefits of this retention technology – designed for fine paper machines – include improved machine stability and drainage control, while more filler can be used to reduce both raw material costs and energy usage because of faster drying.
Another major advantage is increased machine speed and productivity. This was highlighted during 2008 when Compozil Fx helped to create a new world record in China. A customer who operates a coated fine paper machine – running at a paper width of 9.8 meters – reached the fastest-ever production speed of 1,770 meters per minute.
