Mechanical shear forces, cellulose

Cotton cellulose is susceptible to degradation by mechanical shear forces supplied by either a Wiley mill or a Norton ball mill. Mechanoradicals are produced in the interim. [Pg.278]

Stock composition, kinetics of adsorption and hydrodynamic shear dictate the point at which a cationic polymer is added to a papermaking furnish in order to induce flocculation. Flocculation of cellulose fibers in turbulent flow proceeds very rapidly and is completed in less than two seconds.120-123 Flocks form due to charge interactions through a patch-type or a bridging-type mechanism. However, these flocks will be sensitive to shear force and deflocculation and reflocculation might occur. [Pg.681]
