Abstract: [cze] [eng]
Chemická koroze dřeva je závažným problémem, který se často neprojevuje ihned po aplikaci např. ochranné látky. Chemickou korozi dřeva mohou způsobovat jak kyseliny tak zásady. Nebezpečí vzniká především ve střešních konstrukcích, které často bývají ošetřeny retardéry hoření. Chemical corrosion of wood is caused by acids, bases, and salts. Primary manifestations are changes color, next stage is defiberation of wood surface (into a few centimeters). It causes decrease of mechanical properties. Damaged structures (i.e. roof frame) are not capable enough to bear required loads and there is a threat of crash down. Improper use of preservatives on wood can induced process of corrosion what is apparent on some Czech monuments.
