cze Vliv tří komponent z éterických olejů na mechanické vlastnosti lignocelulózových materiálů Tato práce je zaměřena na vliv tří komponent z éterických olejů (eukalyptol, limonen, ocimene) na pevnostní vlastnosti lignocelulózových materiálů před a po expozici. Tyto komponenty, s jejich mikrobicidními účinky a jejich hydrofobním charakterem, by mohly sloužit jako ochrana archivních materiálů na bázi celulózy. lignocelulózový materiál+ esenciální oleje; index pevnosti v tahu; mechanické vlastnosti
eng The Influence of Three Components of Essential Oils on the Mechanical Properties of the Lignocellulose Materials An unsuitable storage of books can cause microbiological attack. The biological attack can be caused by bacteria or fungi. The next type of degradation reaction is hydrolysis, which is supported mainly by increased content of water in books. In this case is degraded the whole cellulose structure. This work is focused on the influence of three components of essential oils (eucalyptol, limonene, ocimene) on strength properties of lignocellulose materials. These components, with their microbicidal effects and their hydrophobic character, could serve as protection of archive materials on cellulosic base. For testing were used cellulosic and lignocellulosic materials, common used in paper industry (coniferous sulphate pulp, deciduous sulphate pulp, sulphite pulp, groundwood, pulp for the production of handmade paper and sample of historical paper). Lignocellulose materials were exposed to saturated vapours of essential oils for 30 and 300 days. The results proved that the mechanical properties didn’t change significantly even after 300 days of exposure. lignocellulose materials; essential oils; tensile index; mechanical properties
