Silicic acid-Boric acid complexes as wood preservatives
2001 - IRG/WP 01-30273
A silicic acid monomer aqueous solution (SAMS) or colloidal silicic acid solution (CSAS) was combined with various metal compounds or boric acid. Agents where SAMS or CSAS was combined with boric acid gave good protection against decay caused by the brown-rot fungus Fomitopsis palustris, the treated wood (Cryptomera japonica D. Don) specimens after the leaching test maintained a high resistance to...
Influence of Acetylation on Fire Resistance of Beech Plywood
2006 - IRG/WP 06-40326
Influence of acetylation on fire resistance was studied in beech plywood. Beech layers were acetylated in a reactor with acetic anhydride at 120ºC for varying durations. Plywoods were made from the acetylated layers and directly exposed to burning flame from their edges for 60s according to ISO 11925-3. Ignition and glowing time were measured in samples. Results were analyzed statistically based ...
