Embodiment 1

[0027] A method for prolonging the service life of wood, comprising the steps of:

[0028] (1) Cutting cleaning treatment:

[0029] Cut the wood first, and then wash the cut wood with water for later use;

[0030] (2) Steam explosion treatment:

[0031] Put the wood treated in step (1) into the steam explosion tank for steam explosion treatment. Firstly, water vapor with a temperature of 103°C is introduced into the steam explosion tank, and the pressure in the steam explosion tank is increased to 0.38MPa. After heat preservation and pressure treatment for 12 minutes, quickly unload the steam explosion tank to normal temperature and pressure, and finally take out the wood and let it cool down to room temperature for later use;

[0032] (3) Primary modification treatment:

[0033] Immerse the wood treated in step (2) into the modified treatment solution A, heat to keep the temperature of the modified treatment solution A at 38°C, take out the wood after ultrasonic vibration ...

Embodiment 2

[0045] A method for prolonging the service life of wood, comprising the steps of:

[0046] (1) Cutting cleaning treatment:

[0047] Cut the wood first, and then wash the cut wood with water for later use;

[0048] (2) Steam explosion treatment:

[0049] Put the wood treated in step (1) into the steam explosion tank for steam explosion treatment. First, put water vapor at a temperature of 105°C into the steam explosion tank, and increase the pressure in the steam explosion tank to 0.40MPa. After heat preservation and pressure holding treatment for 13 minutes, quickly unload the steam explosion tank to normal temperature and pressure, and finally take out the wood and let it cool down to room temperature for later use;

[0050] (3) Primary modification treatment:

[0051] Immerse the wood treated in step (2) into the modified treatment solution A, heat to keep the temperature of the modified treatment solution A at 40°C, take out the wood after ultrasonic vibration treatment ...

Embodiment 3

[0063] A method for prolonging the service life of wood, comprising the steps of:

[0064] (1) Cutting cleaning treatment:

[0065] Cut the wood first, and then wash the cut wood with water for later use;

[0066] (2) Steam explosion treatment:

[0067] Put the wood treated in step (1) into the steam explosion tank for steam explosion treatment. Firstly, water vapor with a temperature of 106°C is introduced into the steam explosion tank, and the pressure in the steam explosion tank is increased to 0.42MPa. After heat preservation and pressure holding treatment for 14 minutes, quickly unload the steam explosion tank to normal temperature and pressure, and finally take out the wood and let it cool down to room temperature for later use;

[0068] (3) Primary modification treatment:

[0069] Immerse the wood treated in step (2) into the modified treatment solution A, heat to keep the temperature of the modified treatment solution A at 42°C, take out the wood after ultrasonic vi...

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a method for prolonging the service life of wood. Background technique [0002] Funan County, affiliated to Fuyang City, Anhui Province, is an early inland development area, located in the northwest of Anhui Province, on the north bank of the junction of the upper and middle reaches of the Huaihe River. Funan County is known as "Famous Specialty Products County" and "Natural Resource Bank". It is a major grain production county in the country, the hometown of willow weaving in China, and the only agricultural (forestry) circular economy demonstration pilot county in the country. Funan is the national willow weaving county. Township, willow products are sold abroad. [0003] Wood is one of the common raw materials in willow products. It is widely used, renewable and has mature processing methods. However, because wood is an ordinary natural wood fiber structu...
