Apparatus for taking up liquid, gas or gas-liquid mixture, e.g. pipe or reactor, with soil-repellant, self-cleaning and/or biocidal surface on liquid and/or gas contacting element to inhibit reduction of flow rates

摘要

In apparatus for taking up liquids, gases or gas-liquid mixtures, at least one element coming into contact with the liquids and/or gases has a soil-repellant, self-cleaning and/or biocidal surface (preferably in the form of a soil-repellant, self-cleaning and/or biocidal coating) : An independent claim is included for the preparation of the apparatus, by finishing (specifically coating) the contacting element with compound(s) (I) providing soil-repellant, self-cleaning and/or biocidal properties.
