Prepustnost sistema les-premaz za vodno paro pri različnih premaznih sistemih

Mihevc, Vekoslav (author), Knehtl, Branko (author), Žepič, Robert (author)

Prispevek predstavlja raziskavo prepustnosti vzorcev lesa smreke/jelke za vodno paro. Vzorci so bili obdelani s petimi različnimi lazurnimi premaznimi sistemi. Za ugotavljanje vpliva staranja filma na prepustnost premaza smo uporabili test umetnega pospešenega staranja, za določevanje prepustnosti za vodno paro pa metodo s čašo (DIN 53122, DIN 52615). Med nestaranimi in staranimi vzorci smo ugotovili značilne razlike v prepustnosti filma premaza. Tudi med posameznimi tipi premazov obstajajo razlike v prepustnosti. Metoda je skupaj z merjenjem navlaževanja lesa med umetnim pospešenim staranjem uporabna za ocenjevanje zaščitne sposobnosti in kakovosti premaznih sistemov.

• Title: Water-vapour permeability of the wood-coating system of different surface coating system

Abstract

The article presents a research of water-vapour permeability of the spruce and fir specimens finished with five different exterior wood film-forming pigmented coating systems based on the Cup method. The samples have been weathered by an accelerated weathering device far over 500 hours. The results of the measurements of water-vapour permeability before and after ageing have shown a decrease in permeability of ali the samples tested. Some major differences in permeability between some types of coating systems have been found. The method, when used together with the water uptake measurement during accelerated weathering, enables qualitative correlations of the coating protection functions of different coating systems.
