Abstract
In order to calculate the work of adhesions in a system comprises of soil/dispersing media/polymer interfaces, the authors calculated the surface tension of solids and discussed these calculating methods.
Surface tension of 12 liquids and their contact angles on paraffin wax, polyethylene and polystyrene were measured.
The dispersion component and polar component of surface tension of these liquids and solids were calculated by applying Fowkes' equation, extended Fowkes' equation (Owens and Wendt's equation) and Wu's equation. (Table-1, Table-7)
The Wu's equation proved to give the most reasonable surface tension component values for the samples chosen to discuss the detergency process.
