    Abstract: A method is provided for decision support in regulating an adhesive coating applied to Yankee dryers. Online sensors are configured to continuously measure stock characteristics, and additional sensors provide actual stock flow rate and machine speed. A controller predicts potential natural coating application from a fibrous sheet generated from the stock to the Yankee dryer surface, substantially in real time, based on the measured characteristics and sensed actual machine values. An output signal may be provided to a display unit, wherein an optimal adhesive coating feed rate may be determined and displayed for operator decision support. The controller may in an automatic mode be configured to regulate the adhesive coating feed rate based on a comparison of one or more determined optimal values associated with respective actual values. The method may include identifying fiber source changes in real time, and predicting a natural coating potential based partly on predetermined correlations.

    Abstract: An anti-corrosion composition containing at least one fatty acid ester, at least one glycol, at least one ethylene oxide/propylene oxide (EO/PO) alkoxylate, at least one polyethylene glycol ester, and at least one modified lecithin is provided. An anti-corrosion composition also is provided which contains at least one fatty acid ester, at least one glycol, at least one sorbate, and at least one modified lecithin. A method of preparing an anti-corrosion composition is also provided. At least one modified lecithin can be blended with at least one fatty acid ester, at least one glycol, at least one EO/PO alkoxylate, or at least one polyethylene glycol ester, or any combination thereof. A method of inhibiting corrosion of a metal surface including applying an anti-corrosion composition to the metal surface in an amount effective to inhibit corrosion of the metal surface is further provided.
