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 کاملThe Drying Kinetics of Protective Coatings Used on Sand Molds
Ł. Jamrozowicz, J. Zych, J. Kolczyk, AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland Investigation results of the drying rate of the selected protective coatings (water and alcohol) are presented in the article. Coating drying rate was determined for the first and second layers. The coating was applied to moulding sand cores. The rate of drying coatings ...
متن کاملModeling Drying of Aqueous Pressure Sensitive Adhesive Coatings
Water-based pressure sensitive adhesives are typically latex suspensions and are often coated onto silicone-coated paper prior to being contacted with the face stock. It is necessary to control drying conditions to achieve low residual moisture in the PSA without formation of defects, and mathematical models can be effective tools to determine appropriate drying conditions. We will present two ...
متن کاملBio-Based Coatings for Paper Applications
The barrier resistance and wettability of papers are commonly controlled by the application of petroleum-based derivatives such as polyethylene, waxes and/or fluorderivatives as coating. While surface hydrophobicity is improved by employing these polymers, they have become disfavored due to limitations in fossil-oil resources, poor recyclability, and environmental concerns on generated waste wi...
