Evaluation of the adhesion interaction of dispersed particles with cellulose fibers

Evaluation of the adhesion interaction of dispersed particles with cellulose fibers Theoretical analysis of the adhesion interaction of dispersed particles with cellulose fibers and of hydrodynamic conditions for detachment of the particles from the fiber surface was performed. The force of the adhesion interaction of the components with the fiber surface was calculated for particles of different configurations with known values of the Hamaker-van der Waals constant. The attraction force of spherical particles to a cellulose fiber wall is 300–400 times lower than that of flat particles. The velocity of flow around the fibers, required for detachment of flat dispersed particles from the fibers, is approximately 1000 times higher than that required for detachment of spherical particles. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

Theoretical analysis of the adhesion interaction of dispersed particles with cellulose fibers and of hydrodynamic conditions for detachment of the particles from the fiber surface was performed. The force of the adhesion interaction of the components with the fiber surface was calculated for particles of different configurations with known values of the Hamaker-van der Waals constant. The attraction force of spherical particles to a cellulose fiber wall is 300–400 times lower than that of flat particles. The velocity of flow around the fibers, required for detachment of flat dispersed particles from the fibers, is approximately 1000 times higher than that required for detachment of spherical particles.
