By measuring adsorption using a stagnation point reflectometer, it was shown that multilayers consisting of cationic polymers and dissolved and colloidal material released from wood fibres into process waters are formed on an anionic silica surface. The similarity of this experiment to the papermaking process was established.It was established using the ''JKR-method'' that this multilayer adsorption...
In the present report the following systems have been studied with the stagnation point adsorption reflectometer (SPAR). (a) Kinetics of the adsorption of cationic polyacrylamide (C-PAM) on silica and comparison with batch experiments of the same types of C-PAM and cellulosic fibres. (b) Deposition of silica particles onto C-PAM pre-covered silica surfaces in order to study the mechanism behind microparticle...
