Abstract

Det er beskrevet en fremgangsmåte for behandling av et porøst materiale Innbefattende dannelse av et trykk- différensial over materialet og behandle høytrykkssiden ved en suspensjon, dispersjon eller aerosol av væskedråper. Dråpene trenger inn i minst noen av porene, hvor behandlingsbetlngelsene er slik at de aerodynamiske kreftene inne i porene overskrider overflatespenningskreftene som opprettholder dråpenes integritet. Dråpene spres derved og danner et overflatebelegg inne i porene.A method of treating a porous material is disclosed, including forming a pressure differential over the material and treating the high pressure side by a suspension, dispersion or aerosol of liquid droplets. The droplets penetrate at least some of the pores, where the treatment conditions are such that the aerodynamic forces inside the pores exceed the surface tension forces which maintain the integrity of the droplets. The droplets are thereby dispersed to form a surface coating within the pores.
