Colour stability of chemically modified oak wood - nanoiron and ammonia treatment

Popis výsledku v původním jazyce

Wood colour and its stability are very important aesthetic aspects of interior-used wood products such as furniture or flooring. Most temperate wood species are characterized by pale inconspicuous colour patterns. These, however can be modified by processes like steaming, heating or ammonia treatment to mimic appearance of tropical wood species (MIKLEČIĆ et al. 2012, TOLVAJ et al. 2012, FEHÉR et al. 2014). Particularly disposed to discolouration in contact with iron and moisture are wood species rich in tannin-like compounds. In these conditions, strongly coloured tannin-iron complexes are produced. Same extractives cause wood darkening if this is exposed to ammonia (FARMER 1967). The current demanded dark surfaces typical for subfossil oak obtaining its colour by contamination with soil iron can be met by targeted impregnation of oak wood with water solutions containing iron particles.
