Rot evaluation in spruce logs and rot reflection into dimensions of chips for particleboards / Viktória Satinová ...[et all.]. -- Obr., tab. -- Lit. - Chips for particleboards (PBs) can be obtained from different tree species or other lignin-saccharide sources. In this work, the following factors are analysed: (1) the degree and type of fungal rot in the Norway spruce (Picea abies) logs using the drill-resistance device “Resistograph” and the acoustic devices “Sylvatest-Duo”, “Fakopp” and “Arbotom”, and (2) following the reflection of wood-rot into dimensions of chips prepared for PBs. Using the devices, milder damage of logs caused by the white-rot Dark honey fungus (Armillaria ostoyae) was not detectable, but on the contrary, more serious damage of logs with the brown-rot Red banded polypore fungus (Fomitopsis pinicola) was clearly detectable. Wood chips prepared from the rotten logs had smaller dimensions compared to chips from the sound logs. By the sieve analysis, using the mesh diameters from 80 mm to 0.125 mm, the total percentage fractions marked as 7, 4, 2, 1, 0.5, 0.25, 0.125 and 0 were 31.1% for chips from the sound logs, 41.89% for chips from logs attacked by white rot, and 71.13% for chips from log attacked by brown rot.
