Problems solved by technology

However, this technology needs to heat up slowly in stages. When cooling, it needs to be cooled to a certain temperature in the treatment tank before it can be taken out, so as to ensure that the material will not crack or deform during the oil bath process. The processing time is longer, so the production efficie...

Embodiment 1

[0058] Take the restructuring bamboo profile as an example. First, the bamboo silk is mixed with the thermosetting phenolic adhesive, the solid content of the adhesive is 30%, and the sizing amount is 10% of the quality of the bamboo silk; then the mixed bamboo silk is dried To the moisture content of 2-5%, after cold pressing and curing, into a 22mm thick profile; then inject the alkyl biphenyl type heat transfer oil into the container and heat it to 100°C for heat preservation; then stack the reconstituted bamboo profiles and use The steel belt is fixed so that the vascular bundle of the profile is parallel to the direction of the oil and steam, so that the heat transfer oil surface is higher than the end face of the reconstituted bamboo, so that the reconstituted bamboo profile is immersed and kept for 10 hours; finally, the reconstituted bamboo profile is taken out and left for 10 minutes After the oil on the surface is automatically sucked into the profile, it is placed in ...

Embodiment 2

[0060] Take the restructuring bamboo profile as an example. First, the bamboo silk is mixed with the thermosetting phenolic adhesive by dipping. The solid content of the adhesive is 45%, and the sizing amount is 25% of the quality of the bamboo silk; then the mixed bamboo silk is dried To the moisture content of 25-30%, after cold pressing and curing to form a profile with a thickness of 20mm; then inject the alkyl naphthalene type heat transfer oil into the container and heat it to 300°C for heat preservation; then stack the reconstituted bamboo profiles and use steel The belt is fixed so that the vascular bundle of the profile is parallel to the direction of the oil and steam, so that the heat transfer oil surface is higher than the end surface of the reconstituted bamboo, so that the reconstituted bamboo profile is immersed and kept for 1 hour; finally, the reconstituted bamboo profile is taken out and left for 2 minutes. After the oil on the surface is automatically sucked i...

Embodiment 3

[0062] Take the restructuring bamboo profile as an example. First, the bamboo silk is mixed with the thermosetting melamine adhesive by dipping. The solid content of the adhesive is 35%, and the sizing amount is 20% of the quality of the bamboo silk; then the mixed bamboo silk is dried To the moisture content of 12-17%, after cold pressing and heating to form a 30mm thick profile; then the vegetable oil is heated to 180℃; then the reconstituted bamboo profile is stacked and fixed with a steel belt so that the vascular bundle of the profile is parallel to the direction of the oil and steam , In this form, make the surface of the heat transfer oil higher than the end surface of the reconstituted bamboo, so that the reconstituted bamboo profile is immersed and kept for 5h; finally, the reconstituted bamboo profile is taken out and rested for 6 minutes, and the oil on the surface is automatically sucked into the interior of the profile and then placed in temperature Cool naturally i...

Abstract

The invention discloses a preparing method of a recombined bamboo sectional bar. The preparing method comprises the steps such as sizing treatment, drying, cold pressing, oil immersion processing and automatic oil sucking. The preparing method has the beneficial effects that the work efficiency is high, the equipment input is less, and the processing effect is even. The prepared recombined bamboo sectional bar is good in mechanical performance, size stability, corrosion resistance and mould resistance.

Description

Technical field [0001] The invention relates to a method for preparing a reorganized bamboo profile improved by reorganization, heat treatment and immersion treatment processes, and belongs to bamboo product production technology. Background technique [0002] my country is a big country of bamboo, with a large output of bamboo and a long history of bamboo utilization. Bamboo has the advantages of good toughness and high strength. It is made into reconstituted bamboo materials in the market and is widely used as raw materials for indoor floors, outdoor floors and furniture. However, bamboo contains a large amount of sugar and protein, and is rich in content, so it is extremely vulnerable to damage and corrosion by bamboo-rot fungi; the presence of lignin, hemicellulose and cellulose makes the dimensional stability of the recombinant bamboo material poor; The reorganization process requires a large amount of adhesives, which brings about the problem of large formaldehyde emission...
