Embodiment 1

[0025] Select the leftover wood of the rotary-cut plank with a thickness of 1.0-2.0 cm, and process the leftover material with high-temperature steam. The steam pressure is 1.5Mpa, and the temperature is 135-140° C. for 1.5 hours.

[0026] Dry the wood to reduce the moisture content of the wood to below 10%, so that the wood can better absorb the resin solution.

[0027] Dip the dried wood into the phenolic resin solution for 10 minutes, so that the wood can fully absorb the resin.

[0028] The drying temperature is controlled to be 55° C., and the impregnated wood is dried to make its moisture content 12-18%.

[0029] Bind the wood into a uniform handle with a length of 1.93 meters and a weight of 3-10Kg.

[0030] The handle is pressed into shape with a hydraulic press, and the pressure is 17-18Mpa.

[0031] The pressed semi-finished product is sent to the high-temperature curing equipment for consolidation and shaping, so that the phenolic adhesive is fully consolidated. ...

Embodiment 2

[0033] Select high-tech wood scraps with a thickness of 0.5-0.8 cm, and process them with high-temperature steam. The steam pressure is 1.5Mpa, and the temperature is 135-140°C. Treat for 3 hours, and disperse the glued scraps while they are hot.

[0034] Dry the wood to reduce the moisture content of the wood to below 10%, so that the wood can better absorb the resin solution.

[0035] Dip the dried wood into the phenolic resin solution for 7 minutes, so that the wood can fully absorb the resin.

[0036] The drying temperature is controlled to be 50°C, and the soaked wood is dried to make its moisture content 12-18%.

[0037] Bind the wood into a uniform handle with a length of 1.93 meters and a weight of 3-10Kg.

[0038] The handle is pressed into shape with a hydraulic press, and the pressure is 17-19Mpa.

[0039] Send the pressed semi-finished product to the high-temperature curing equipment for consolidation and shaping, so that the phenolic resin is fully consolidated....

Embodiment 3

[0041] With specific embodiment 1 through steam treatment, oven dry, dipping, the rotary cut plank leftover after gluing post-drying treatment, and specific embodiment 2 after steam treatment, oven dry, dipping, gluing post-drying treatment The technological wood leftovers are arranged alternately and bundled into uniform handles with a length of 1.93 meters and a weight of 3-10Kg. Use a hydraulic press to press the leftover handle into shape with a pressure of 17-18Mpa; consolidate the pressed semi-finished product at a high temperature of 150°C for 14 hours to obtain a finished recombined modular wood product. The wood pattern pattern of this module is more abundant.

Abstract

The invention discloses a method of recombined module wood production by using secondary processing wood such as peeling board or reconstituted decoration lumber scrap. The method includes the steps of: vapor treating at a high temperature or digesting in oxydol and caustic soda, drying, gumming, further drying after being gummed, trimming, compression moulding, consolidating at a high temperature and obtaining the recombined module wood; the density of the obtained wood reaches 0.8-1.2kg/cm<3>, and the obtained wood has unique texture, fine texture and superior performance, and no need for treatments of insect prevention, mold prevention, corrosion resistance and cracking prevention. The obtained wood can be directly applied to fields of flooring, furnishing, building, etc., and is characterized by cracking resistance, deformation resistance and so on. The method has simple procedure, makes good use of the waste and greatly saves the forest resource by producing module wood with the waste secondary processing wood, 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 recombined modular wood by using sub-processed wood such as veneer and veneer 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 resi...
