Abstract
The occurrence of charges on solid surfaces and the properties of electrical double layer were explained first, and some kinetic aspects on polymer additives in the wet-end were described.<BR>Under turbulent flow conditions the adsorption of polymers on fibers and fillers is very rapid occuring in less than 1 second. The adsorbed polymers will reconform to a less expanded configuration which attains equilibrium state within 2-3 minutes. The reconformation process influences the flocculation efficiency of the adsorbed polymer. When the flocs are destroyed by the turbulence, the retained polymers can transfer between fibers and fillers, and the polymer chains can also be cleaved. The penetration of adsorbed polymers into fiber pores occurs very slowly.<BR>It is possible that both the retention and the formation can be improved simultaneously, though the two are usually antinomic phenomena. But most of them are dependent on an ability of engineers at the paper mills.
