Problems solved by technology

The impregnation process of this technology requires a high-pressure environment, followed by vacuuming, and the impregnation process is complicated. The composite material is subjected to high-temperature heat treatment in the mold (hot press equipment), and the materials between the two processes need to be loaded and unloaded repeatedly. The process technology has high requirements on equipment, the effect of hot pressing treatment is uneven, the size (especially thickness) of the material that can be processed has certain limitations, the production efficiency is low, the depth of impregnation is small, and the degree of heat treatment is shallow

Embodiment 1

[0050] Taking the bamboo flat timber as an example, firstly control the moisture content of the bamboo flat timber in the range of 2-5% by drying treatment, and the thickness of the bamboo flat timber is 22mm; then inject the alkyl biphenyl type heat transfer oil into the container, and Heat to 100°C and keep warm; then stack the flat bamboo materials, fix them with steel belts so that the vascular bundles of the profiles are parallel to the direction of the oil hot steam, and impregnate in this way, so that the surface of the heat transfer oil is higher than the end surface of the recombined bamboo, so that the recombined bamboo The bamboo profile is submerged and kept for 10 hours; finally, take out the bamboo flat material and let it stand for 10 minutes. After the oil attached to the surface is automatically absorbed into the profile, it is then placed in an environment with a temperature of 30°C and a relative humidity of 60% for cooling. The obtained modified bamboo flat ...

Embodiment 2

[0052] Taking the recombined bamboo profile as an example, first mix the bamboo silk and the thermosetting phenolic adhesive by dipping, the solid content of the adhesive is 45%, and the sizing amount is 25% of the mass of the bamboo silk; then the mixed bamboo silk is dried The moisture content is 25-30%, and after cold pressing and heat curing, it becomes a profile with a thickness of 20mm; then inject alkyl naphthalene heat transfer oil into the container, and heat it to 300°C to keep it warm; then stack the recombined bamboo profiles, and use steel Fix the vascular bundle of the profile parallel to the direction of the oil hot steam, and impregnate in this way, make the surface of the heat transfer oil higher than the end surface of the restructured bamboo, immerse the recombined bamboo profile, and keep it for 1 hour; finally, take out the recombined bamboo profile and let it stand for 2 minutes. After the oil attached to the surface is automatically sucked into the inside...

Embodiment 3

[0054] Take the bamboo flat timber as an example, firstly control the moisture content of the bamboo flat timber in the range of 12-17% by drying treatment, and the thickness of the bamboo flat timber is 22mm; then inject the alkyl biphenyl type heat transfer oil into the container, and Heat to 200°C and keep warm; then stack the flat bamboo materials, fix them with steel belts so that the vascular bundles of the profiles are parallel to the direction of the oil hot steam, and impregnate in this way, so that the surface of the heat transfer oil is higher than the end surface of the recombined bamboo, so that the recombined bamboo The bamboo profile is submerged and kept for 5 hours; finally, take out the bamboo flat material and let it stand for 6 minutes. After the oil attached to the surface is automatically absorbed into the profile, it is then placed in an environment with a temperature of 30°C and a relative humidity of 60% for cooling. The obtained modified bamboo flat pr...

Abstract

The invention discloses an oil-heating and dipping treatment technology for bamboo wood. The technology comprises the steps of drying, oil dipping treatment process, automatic oil suction and the like. The maximum treatment thickness of flattened bamboo wood, recombined bamboo wood, laminated bamboo wood, reconsolidated bamboo wood, bamboo skins or bamboo filament materials is 40 mm. The technology has the characteristics of being simple, high in working efficiency, low in equipment investment and uniform in treatment effect. The bamboo wood made through the technology has the optimal mechanical property, dimensional stability, corrosion resistance and mildew resistance.

Description

technical field [0001] The invention relates to a heat treatment and dipping treatment method of bamboo, in particular to a heat treatment and dipping treatment method using oil as a medium. Background technique [0002] my country is a big bamboo country with a large output of bamboo and a long history of planting and using bamboo. Bamboo has the advantages of good toughness and high strength. In the home improvement building materials market, it is made into flattened bamboo and recombined bamboo materials, which are widely used in the processing and production of indoor and outdoor flooring and furniture. However, bamboo contains a large amount of sugar, protein, and rich content, so it is very vulnerable to the infringement and corrosion of bamboo rot fungi; the existence of lignin, hemicellulose and cellulose makes the dimensional stability of the recombined bamboo material poor; the above problems Both put forward a severe test for the durability and stability of bamb...
