摘要

Thermal condensation of glucose-diammonium phosphate in wood at 160 and 190pC will protect wood against fire and decay in one treatment using an aqueous system. For fire protection, treatments at 160 or 190pC led to low flammability as evidenced by fire-tube tests. For nonleached wood, weight losses were 1.9, 2.0, and 2.0% with chemical retentions of 56.7, 44.7, and 64.7%, respectively, for 2-, 4-, and 6-h heating; and for leached wood, weight losses of 5.1, 3.8, and 1.5% with chemical retentions of 24.5, 24.1, and 45.6%, respectively, for 2-, 4-, and 6-h heating compared with 18.8% weight loss for diammonium phosphate-treated wood with chemical retention of 19.4%. The control had 84.4% weight loss. For decay protection, heat treatment at 190pC for 30 min after 2-wk water leaching also prevents degradation by brown and white rot fungi. Weight loss by Gloeophyllum trabeum (Gt) was 0.4% with 19.5% chemical retention, and weight loss by Trametes versicolor (Tv) was 1.5% with 17.8% chemical retention. The control had 30.6 and 36.8% weight losses by Gt and Tv, respectively.
