Embodiment 1

[0026] Select mulberry branches with a diameter of 3 to 80 mm, and use a crusher to radially crush them along the wood fiber direction. The radial dimension of the crushed mulberry branches is 3 to 5 mm. Bundle the broken mulberry branches into uniform handles with a length of 193-250 cm and a weight of 3-4 kg.

[0027] The bundled mulberry branches were put into boiling water and boiled for 2 hours to degrease; then carbonized with steam carbonization equipment, the steam pressure was 1.5kg, and the carbonization treatment time was 3 hours.

[0028] The carbonized mulberry branches are dried to make the water content less than 10%.

[0029] Dip the dried mulberry branches into phenolic glue for 15 minutes, so that the broken mulberry branches can fully absorb the glue.

[0030] The drying temperature is controlled to be 50° C., and the dipped mulberry branches are dried so that the moisture content thereof is 10% to 18%.

[0031] Put the dipped and dried raw materials into ...

Embodiment 2

[0034] Select the green sandalwood with a diameter of 3-200mm, and carry out radial crushing along the wood fiber direction with a crusher. The radial size of the broken green sandalwood is 3-5mm. Bundle the broken green sandalwood into a uniform handle with a length of 193cm and a weight of 3-4kg.

[0035] Put the bundled green sandalwood into boiling water for 3 hours to degrease; then use steam carbonization equipment for carbonization treatment, the steam pressure is 1.5kg, and the carbonization treatment time is 3.5 hours.

[0036] The carbonized green sandalwood is dried to make its moisture content less than 10%.

[0037] Immerse the dried cedarwood in phenolic glue for 20 minutes, so that the broken cedarwood can fully absorb the glue.

[0038] The drying temperature is controlled to be 50° C., and the dipped green sandalwood is dried to make its moisture content 10% to 18%.

[0039] Put the dipped and dried raw materials into a 2.5-meter-long rectangular mold and pr...

Abstract

The invention discloses a method for replacing log with second smallest fuelwood to produce module wood. After the steps of crushing, degradation, drying, dipping, drying, compression molding, curing, etc., the second smallest fuelwood is glued into the module wood or profile. The module wood made in the method has the advantages of keeping original fibrous tissue, texture and performance, having ultrahigh hardness, compressive strength, shock resistance, and anti-distortion capacity, eliminating the need for corrosion, insect and water prevention directly and being directly made into floors, furniture, building equipments, etc. In the method, the second smallest fuelwood such as small branches, small woods, etc., are utilized and processed to make the module wood so as to save resources and changes waste into valuables, thus being an ideal substitute of the log.

Description

technical field [0001] The invention relates to a production process of modular wood, in particular to a method for producing modular wood by using sub-small fuelwood instead of logs. Background technique [0002] At present, in the world, with the rapid development of furniture, flooring, paper and other industries, a large number of log resources are consumed, and forest resources are decreasing day by day, which not only causes great damage to forest resources, but also causes soil erosion, Environmental degradation and other issues. However, the market demand for furniture and flooring is still increasing. [0003] When using logs to produce modular wood, it is necessary to carry out a long period of aging treatment, degreasing, anti-corrosion and other pretreatments on the logs, and a lot of leftovers are produced during the processing. Most logs also have shortcomings such as cracking, deformation, water resistance, and light resistance. [0004] Chinese patent appl...
