Embodiment 1
[0015] After treating the wood with Cu-8C organic solvent preservatives with concentrations of 0.5% and 1.0% respectively, the A-type wooden window frame was made. The test results showed that:
[0016] (1) Anti-mold performance measured according to GB / T 18261-2000: when the agent concentration is 0.5wt%, the average mold damage value (D) is 0.11, the control effect (E) is 96.77%, the color-changing bacteria damage value (D) is 0.00, and the control effect is 0.00. Effectiveness 100%;
[0017] (2) Antiseptic properties measured according to LY / T 1283-2011: the toxicity limit for Coriolus versicolor is 1.4~2.0kg / m 3 , the toxicity limit to the yellow spore fungus is 1.5~1.8kg / m 3 , the anti-corrosion effect is very good;
[0018] (3) According to GB / T 18260-2000, the anti-termite performance is measured: when the concentration of the agent against termites is 1.0%, the degree of moth is 1.0%, the weight loss rate of treated wood is 2.5%, and the termite mortality rate is 97....
Embodiment 2
[0024] The wood was treated with ASDB flame retardant preservative with a concentration of 10% to make B-type wooden window frames. After testing, the results showed that:
[0025] (1) Flame retardant properties measured according to GB / T 2406.2-2009
[0026]
[0027] (2) According to LY / T 1283-2011, the anticorrosion performance was measured: the average loss rate of Poria decumbens was 0.45%, the average loss rate of Coriolus versicolor was 0.23%, and their toxicity limits were all below 1.0%;
[0028] (3) Insect-proof performance measured according to GB / T 18260-2000: against domestic termites, when the pesticide concentration is 1.0%, the failure rate of the treated wood is 3.8%, and the termite mortality rate is as high as 95.9%.
Embodiment 3
[0030] The C-shaped window frame made of high-temperature heat-treated modified wood has undergone functional tests, and the results show that:
[0031] (1) Measured according to GB / T 4739-1995: After treatment, the "brightness" of wood generally decreases, the "chromaticity index" increases, and the "color difference" increases;
[0032] (2) Measured according to GB / T 1933-2009: the density of treated wood generally decreases;
[0033] (3) Measured according to GB / T 1931-2009: the equilibrium moisture content is between 5.7 and 6.6%;
[0034] (4) Dimensional stability measured according to GB / T 1932-2009, GB / T 1934.1-2009, GB / T 1934.2-2009: After treatment, the hygroscopicity of wood is reduced by 5.8%, the water absorption is reduced by 22.5%, and the wet swelling is reduced by 54.0% %, relatively speaking, the dimensional stability is greatly improved;
[0035] (5) Measured according to GB / T 1939-2009: the average compressive strength of wood after treatment increases by ...
