Embodiment 1

[0035] Cut 30m3 wood into wood with a length of 100cm and a thickness of 2cm; then immerse it in a 20% lime water solution and boil it for 5 hours, then rinse it in clean water, and then immerse it in a 1‰ hydrogen peroxide solution. Boil for 5 hours, then rinse it in clean water; then adjust the temperature in the conventional steam drying kiln to 72°C, and spray water vapor into the conventional steam drying kiln to make it saturated, and then put the degreased wood into the conventional steam drying kiln. The steam drying kiln fully absorbs water. After 25 hours, the masson pine wood absorbs water to a saturated state, then stops spraying water vapor, adjusts the temperature in the conventional steam drying kiln to 65℃, stuffs the kiln for 12 hours, and then opens the vent to exhaust air. The temperature in the conventional steam drying kiln was gradually increased to 82°C, and the dehydration was carried out for 3 hours; this was repeated twice, and then the moisture content...

Embodiment 2

[0039] 30m3 of masson pine wood latewood is cut and sawed into wood with a length of 200cm, a width of 15cm, and a thickness of 5cm; then it is immersed in a 20% lime aqueous solution and boiled for 6 hours, then rinsed in clean water, and then immersed in The concentration of 1‰ hydrogen peroxide solution is continuously boiled for 6 hours, and then rinsed in clean water; then the temperature in the conventional steam drying kiln is adjusted to 76℃, and steam is sprayed into the conventional steam drying kiln to make it saturated. Put the defatted masson pine wood into a conventional steam drying kiln to fully absorb water. After 28 hours, the masson pine wood absorbs water to a saturated state, then stop spraying water vapor, adjust the temperature in the conventional steam drying kiln to 68℃, and keep the kiln for 14 hours. Then open the vent to exhaust the air, and gradually increase the temperature in the conventional steam drying kiln to 85°C for 4.5 hours of dewatering; r...

Embodiment 3

[0043] Cut 30m3 wood into wood with a length of 300cm and a thickness of 6cm; then immerse it in a 20% lime aqueous solution and boil it for 6 hours, then rinse it in clean water, and then immerse it in a 1‰ hydrogen peroxide solution. Boil for 6 hours, then rinse it in clean water; then adjust the temperature in the conventional steam drying kiln to 78℃, and spray steam into the conventional steam drying kiln to make it saturated, and then put the degreased wood Enter the conventional steam drying kiln to fully absorb water. After 30 hours, the wood will absorb water to a saturated state, then stop spraying water vapor, adjust the temperature in the conventional steam drying kiln at 70°C, stuff the kiln for 15 hours, and then open the vent to exhaust air. The temperature in the conventional steam drying kiln is gradually increased to 87℃, and the dehydration is carried out for 5 hours; this is repeated 4 times, and then the moisture content of the wood is checked until the mois...

Abstract

The invention discloses a production method of charred compound wood, belonging to the technical field of processing of forest products. The charred compound wood is produced by three working stages of common solid wood processing, homogeneous charred wood processing and charred compound solid wood processing. The production method has the beneficial effects that common solid wood and homogeneous charred wood have basically same characteristics by adopting common solid wood and homogeneous charred wood which are processed in the same batch as raw materials, and thus the rejection ratio of the charred compound solid wood product is greatly reduced. The charred compound wood is particularly suitable for an outer wall of a wooden house so that the clear color of log on the indoor wall space can be kept, the chemical preservation is replaced and the anti-corrosion property of the outdoor wall space is greatly improved. The charred compound wood can be produced by adopting masson pine wood as a raw material, and thus the application field of the masson pine wood is greatly enlarged, the economical value is increased, valuable timbers and tree species can be replaced, and the contribution is made for maintaining natural forest resources and protecting the nature environment.

Description

Technical field [0001] The invention belongs to the technical field of forestry product processing, in particular to a production method of carbonized composite wood that uses homogenous carbonized wood and conventional solid wood as raw materials to be processed into composite wood. Background technique [0002] As non-renewable resources are depleted and the environment is overwhelmed, my country’s resources and environment are facing a very severe test. To ensure the long-term sustainable development of the national economy, renewable resources should be fully utilized. [0003] Fast-growing forest wood is a recyclable engineering material. The use of my country’s rich fast-growing forest wood resources to develop environmentally friendly and recyclable wood has great social significance for energy conservation and emission reduction, and the construction of a resource-saving and environment-friendly economic cycle system. . [0004] Since my country has already begun to implement...
