Embodiment 1
[0020] A processing method for high-strength wood, step A, according to parts by mass, dry 100kg of wood (the density of wood is 0.35 / cm 3 , thickness is 5cm) fixed in the reaction kettle, 500kg of water, make the water completely submerge the wood, heat the water to boiling, add 50kg of sodium hydroxide, 40kg of sodium metabisulfite and 10kg of calcium hydroxide after 5 minutes to continue the boiling reaction 10h; after the reaction is completed, drain the liquid, add 500kg of water again, boil for 20 min, repeat twice and then take out the wood.
[0021] Step B. Put the wood in a hot press, control the temperature at 110-105° C., press at 6 MPa, and press for 18 hours to obtain a high-strength wood.
[0022] Step C, after the wood is processed into the required shape, anticorrosion treatment is carried out by the brushing method.
[0023] The sample number is QW-1.
Embodiment 2
[0025] A kind of processing method of high-strength wood, step A, according to mass parts, 125kg wood after drying (the density of wood is 0.42 / cm 3 , the thickness is 10cm) fixed in the reaction kettle, 750kg of water, make the water completely submerge the wood, heat the water to boiling, add 75kg of sodium hydroxide, 50kg of sodium metabisulfite and 12kg of calcium hydroxide after 8min and continue to boil for 12h ; After completing the reaction, drain the liquid, re-add 750°C of water, boil for 25 minutes, and take out the wood after repeating twice.
[0026] Step B. Put the wood in a hot press, control the temperature at 120-125° C., press at 7.5 MPa, and press for 15 hours to obtain a high-strength wood.
[0027] Step C, after the wood is processed into the required shape, anticorrosion treatment is carried out by diffusion method.
[0028] The sample number is QW-2.
Embodiment 3
[0030] A processing method for high-strength wood, step A, according to parts by mass, dry 150kg of wood (the density of wood is 0.45 / cm 3 , the thickness is 12cm) fixed in the reaction kettle, 1000kg of water, make the water completely submerge the wood, heat the water to boiling, add 100kg of sodium hydroxide, 60kg of sodium metabisulfite and 15kg of calcium hydroxide after 10min and continue to boil for 14h After completing the reaction, drain the liquid, add 1000kg of water again, boil for 30min, and take out the wood after repeating twice.
[0031] Step B. Put the wood in a hot press, control the temperature at 125-130° C., press at 9 MPa, and heat press for 12 hours to obtain a high-strength wood.
[0032] Step C, after processing the wood into the desired shape, carry out anti-corrosion treatment with hot and cold bath method.
[0033] The sample number is QW-3.
