FIBRE PROCESSING WORLD PULPPAPER22 During the last decade paper producers have continually pushed more ash and alternative fibre sources to improve costs and satisfy market demands. These changes have caused sheets to be less robust than their low ash virgin fibre counterparts. In addition to the increase in chemistries used Cellulose NanoFibril CNF Technology has begun to be deployed for additional strength and modified sheet properties. CNF has been a talking point within the industry for many years however the FibreFine System now allows the papermaker to produce CNF pulp using known industry equipment. In addition to adding CNF internally at a stock chest we now have the ability to add CNF on the surface using the Hydra-Sizer Applicator. FIBREFINE SYSTEM The heart of the FibreFine System is GLVs DD6700 Disk Refiner. It was designed with high efficiency and optimum fibre development in mind. CNF production is optimised using proprietary plate design and GLVs Anti-Plate Clash System APCS. This results in the ability to provide optimum fibre development at the lowest energy while maintaining plate integrity. The DD6700 technology has the unique advantage of having 50 more capacity as compared to similar sized refiners. This allows installation of smaller refiners with less energy demand and less cost to maintain. This technology and operation is very Cellulose Nano Fibrils CNF is forced out of a narrow slot in the applicator and is applied as a full-width curtain onto the wet stock. These units come By David Cowles Global Business Manager-Nanotechnologies GLV USA Inc. FibreFine - The Newest Tool in the Papermakers Toolbox similar to products already in most paper mills and existing machinery can be adapted to produce CNF. FIBREFINE HYDRA-SIZER APPLICATOR The Hydra-Sizer technology features a special applicator that is positioned on the Fourdrinier with an adjustable structure and an additive supply system. A liquid dispersion of in two versions a linear model which applies CNF at a constant rate across the machine width and a profiling version which can vary the addition rate in a number of distinct zones across the machine. One of the key benefits of the Hydra-Sizer applicator is the near 100 retention of your CNF solution and being able to apply it on one side of the sheet for specific property modification. Figure 1.
