Embodiment 1

[0067] Choose 1.0-1.5mm thick rotary-cut technical wood scraps, place them in an autoclave, and feed them with high-temperature steam for 1-1.5 hours. The steam pressure is 3Mpa, and the temperature is 135-140°C.

[0068] After leaving the kettle, shake it while it is hot, and let it stand for 1 to 7 days to reduce the moisture content of the veneer to below 20%, so that the wood can absorb glue better.

[0069] On the chain sizing equipment, apply glue to the veneer, use phenolic resin solution, and soak the glue for 1 minute, so that the veneer can fully absorb the glue.

[0070] Hang the veneer after dipping on the conveyor frame, and drain the excess glue on the veneer.

[0071] Dry at a temperature of 55°C to make the moisture content 10-20%.

[0072] Bundle the veneer into a uniform handle with a length of 1.93 meters and a weight of 3-10Kg.

[0073] Put the handle in the balance health room for 3 to 15 days. The temperature in the balanced health care room is control...

Embodiment 2

[0077] Choose miscellaneous wood poles with a diameter of 3-8cm, put some miscellaneous wood poles into the planing equipment, and plan them into thin wood chips with a thickness of 0.5-1.5mm.

[0078] Cook with 2% hydrogen peroxide for 1.5 hours.

[0079] Treat it with high-temperature steam for 2.5 hours, the steam pressure is 2Mpa, and the temperature is 115-125°C.

[0080] It is dipped on the chain sizing equipment, using phenolic resin solution, and the dipping time is 1 minute, so that the veneer can fully absorb the glue.

[0081] Put the dipped veneer into the frame and drain off the excess glue. The time for draining the glue is 0.5-2 hours.

[0082] After gluing, dry at a temperature of 50°C, and dry the veneer after gluing to make the water content 10-20%.

[0083] Place the dried veneer in a balanced health care room for 3 to 15 days. The temperature in the balanced health care room is controlled at 30°C and the humidity is controlled at 65%, so that the moisture...

Embodiment 3

[0087] Choose 1.0-1.5mm thick rotary-cut technical wood scraps, place them in an autoclave, and feed them with high-temperature steam for 1-1.5 hours. The steam pressure is 3Mpa, and the temperature is 135-140°C.

[0088] After leaving the kettle, the original adhesive of the technological wood will fail, and the veneer will be shaken off while it is hot.

[0089] Weave thin wood chips into rope with a rope braiding machine.

[0090] It is dipped on the chain sizing equipment, using phenolic resin solution, and the dipping time is 1 minute, so that the veneer rope can fully absorb glue.

[0091] Drain the excess glue on the thin wood rope after dipping, and the time for draining the glue is 0.5 to 2 hours.

[0092] After gluing, dry at a temperature of 58° C., and dry the veneer after gluing to make the water content 10-20%.

[0093] Place the dried veneer ropes in a balanced health care room for 3 to 15 days. The temperature in the balance health care room is controlled at ...

Abstract

The invention relates to a method for producing high-density recombined wood, which is used for manufacturing plates and recombined module timber by the following steps of planning, processing by high-temperature steam, drying, dipping glue, draining glue, drying after draining glue, tidying or weaving, balancing for nourishing, pressing to shape, solidifying at a high temperature and the like. The density of the high-density recombined wood can reach 0.7-1.2kg / cm<3>; the high-density recombined wood has the characteristics of peculiar texture, fine grain, excellent performance, small possibility of cracking and deforming and the like, does not need to prevent insects, prevent mildew, prevent corrosion, prevent from cracking and the like, and can be directly used for the fields of floor, furniture, building and the like. The method disclosed by the invention has simple working procedures, and abandoned secondarily secondary small fuel wood and secondary small wood are utilized to produce plates and module wood, thereby changing waste materials into things of value, and greatly saving forest resource. The wood is an ideal log substitute.

Description

technical field [0001] The invention relates to a production process of recombined wood boards and recombined wood modular materials, which uses fast-growing wood, small-diameter wood, fuel wood, and secondary processed wood as raw materials, especially a method of using thin wood chips to replace logs to produce reorganized wood boards and Method for recombining timber modular materials. Background technique [0002] Overexploitation of resources, environmental pollution, and climate warming have become indisputable facts. With the rapid development of furniture, flooring, and papermaking 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. Destruction has also caused problems such as soil erosion and environmental degradation. However, the market demand for furniture and flooring is still increasing. [0003] When using logs to produce boards, the utilization rate...
