Course content
The basic terms of surface and colloid chemistry as surface tension and energy, specifical surface and degree of dispersity, 3D molecular and hypermolecular space nets - gels and fibrous nets. Surface processes at two-phase interfaces - Gibb`s adsorption isotherme. The main groups of substances influencing hyper-molecular behaviour - tenzides, polyelectrolytes, hydrophilic celulosic materials. Surface processes at three-phase interfaces - Young`s eq., adhesion work, wettability assesment of surfaces, characterization of surfaces according to Zisman, Fowkes-Goog and van Oss. Capillary processes - capillary elevation and depresion, cappilary phenomenons in wetted and non-wetted capillaries, Laplace`s eq. Capillary phenomennons as vapour tension of liquids in capillary - Kelvin`s eq. The processes in interfaces of dispersion systems - the theory of stability of dispersion systems. Intermolecular bonds in interfaces and 3D space nets - van derWaal`s and hydration forces. Kinetic of processes in dispersion systems. Practical hyper- and supra-molecular processes - gluening, theory of adhesion, paper hygroscopicity. Transport processes in porous materials - penetration, diffusion, capilary flow, impregnation. Rheology of liquid dispersion systems - basic types of flow curves, explanation and control this behaviour, coatings colours, anomalic temperature flow behaviour. Technologic aspects of papermaking systems - paper sizing, retention,rheosedimentation.
