The influence of heat treatment on granularity of sand wood dust

Očkajová, Alena, 1961- The influence of heat treatment on granularity of sand wood dust / Alena Očkajová, Martin Kučerka, Adrián Banski. -- The paper deals with the granular analysis of the sand dust of heat-treated wood from red meranti, depending on the treatment temperature of 160 °C, 180 °C, 200 °C and 220 °C. The proportion of dust fractions with a particle size ≤ 0.08 mm was determined by sieving. The percentage shares of these fractions are similar for natural wood 84.17 % and temperature of treatment at 160 °C (87.18 %), 180 °C (86.23 %) and 200 °C (80.79 %). A significantly lower proportion of dust fractions with a particle size ≤ 0.08 mm occurred at a temperature of 220 °C, only 74.48 %. We assume that the main factor that caused the decrease of the dust fraction with a particle size ≤ 0.08 mm at 220 °C is the reduction of wood density
