Microwave Drying of Paper Documents
A new advanced microwave drying technology has been developed using a continuous dryer combined with an air cooler. Principle of the new technology consist in using microwave absorption filters made from special porous ceramics which act as both absorbent and transparent material for microwaves. Ceramic slabs reduce intensity of microwave radiation to such a extent which prevents overheating or...
متن کاملSelf-similar roughening of drying wet paper.
We studied the kinetic roughening dynamics of drying wet paper. The configurations of dry paper sheets are found to be self-similar, rater than self-affine. Accordingly, the paper roughening dynamics corresponds to the new class of anomalous kinetic roughening [J. J. Ramasco, J. M. López, and M. A. Rodríguez, Phys. Rev. Lett. 84, 2199 (2000)], characterized by the equal local and global roughne...
متن کاملHigh Resolution Optical Measurement Techniques in Paper Drying
In the scope of this paper, we present the application of three non-invasive optical measurement techniques for the investigation of paper drying process with a high spatial and temporal resolution. These techniques are based on digital image sequence processing with images acquired at different wavelengths ranging from visual to far infrared. Such spectral imaging techniques combine the potent...
متن کاملFundamentals of Paper Drying – Theory and Application from Industrial Perspective
No manufactured product plays a more significant role in every area of human activity than paper and paper products. Its importance in everyday life is obvious from its use in recording, storage and dissemination of information. Virtually all writing and printing is done on paper. It is the most widely used wrapping and packaging material, and is important for structural applications. The uses ...
متن کاملSolid insulation drying of 110 kV paper-oil instrument transformers
Influence of moisture on the instrument transformers’ paper-oil insulation and its further maintenance is described in this paper. Improved insulation drying method using vacuum and temperature regulation with definite regulation algorithm of parameters is proposed and analyzed by comparing it with conventional drying method.
