Ceramic components e.g. roofing tile, photocatalytic surface coating testing method, involves applying dye on testing area, where color and/or light absorption and/or fluorescence of area are detected

摘要

The method involves applying a living microorganism on a testing area of a photocatalytic surface coating of a ceramic component using a microorganism application device (30a). Dye is applied on the area and formed such that viability of the organisms to the color and/or light absorption and/or fluorescence of the dye is readable. The color and/or light absorption and/or fluorescence of the area are detected. The dye is selected from a group of chlorophyll, 4'-6-Diamidino-2-phenylindole, acridinorange, calcoflourwhite, methylene blue, methyl orange and indigo carmine. An independent claim is also included for a device for non-destructive testing of a photocatalytic surface coating of ceramic components such as roofing tile.
