Winter 2008-2009 Newsletter AVAILABLE NOW: PAPERMAKING NANOTECHNOLOGY	John Penniman
The 1840 Fourdrinier process is reinforced by the 21st century revolutionary nanotechnology process. Dispersion of chemicals to nano-molecular dimensions achieves stock homogeneity, enabling a chemical efficiency increase of 1 to 2 orders of magnitude.  To ensure maximum efficiency, it is quantified by a sensor and adjusted to optimum via closed loop computer.  RESULT: Reduce chemical usage by 90-99% and chemical costs from $1,000,000/year, for example, to less than $100,000 Retention is maximized at the highest level of formation by closed loop control of the key process parameters.  RESULT: Closed loop computer control enables the highest possible level of quality Energy conservation is maximized by two means:  on-line control of surface tension at about one-third the usual value on the wet end, and azeotropic removal of water on the dry end to expedite the process, and continued use of surface tension to reduce the hydrogen bonding of water.  RESULT: Reduce energy usage by 40-60% As a result of these and other innovations, sustainability is superb SPECIAL NOTE: Papermaking nanotechnology is much more efficient than the conventional process, thereby enabling either re-builds or new machines to be constructed with about half the conventional machinery and equipment and about half the cost.   Respond to:  john-penniman@papermaking-chemistry.com Return to Home Page
