Tiivistelmä
The objective of this thesis was to find out if foam coating could be applied to non-woven filtration media. The goal was to increase collection efficiency without significantly decreasing air permeability.
In the theoretical part, foams and their characteristics were the centre of attention. Coating in general and, of course, foam coating were also studied. The empirical part consisted of series of foaming experiments and pilot scale coating experiments. In the foaming experiments different coating fibres and foaming agents were tested.
Despite a persisting fibre flocculation problem, there were some promising results. Unfortunately the project ran out of funds before any commercially applicable results were achieved.
The appendices of this thesis include confidential information.
