Problems solved by technology

[0003] The first type of treatment method is not ideal because the bamboo still contains more sugar and cannot be wrapped or sealed completely, so the anti-mildew effect is not ideal; the second type of treatment method has a darker color because the mechanical properties of the bamboo are greatly damaged due to excessive temperature , the scope of application is not wide, which affects the scope of use of the product
Both of the above two treatment methods will produce irritating odor during the production process, and are difficult to handle, which will have a certain impact on the environment

Embodiment 1

[0050] Embodiment 1 of the present invention provides a kind of bamboo wood desugaring method, comprises the following steps:

[0051] (1) Bamboo pretreatment: After the bamboo is rolled, it is set aside;

[0052] (2) Desugar treatment: immerse the bamboo obtained in step (1) in water, add solid alkali, and treat for 1 hour.

[0053] In step (2), the solid base is magnesium oxide.

[0054] In step (2), the added amount of the solid alkali is 0.2% of the bamboo mass.

[0055] In step (2), the mass ratio of the bamboo to water is 1:4.

[0056]In step (2), the treatment temperature is 160°C.

[0057] In step (2), the treatment pressure is 0.6MPa.

[0058] Embodiment 1 of the present invention also provides an application of the method for desugaring bamboo as described above, which is used for desugaring bamboo to produce heavy bamboo boards and by-products suitable for outdoor use.

Embodiment 2

[0060] Embodiment 2 of the present invention provides a kind of bamboo wood desugaring method, comprises the following steps:

[0061] (1) Bamboo pretreatment: After the bamboo is rolled, it is set aside;

[0063] In step (2), the solid base is magnesium hydroxide.

[0064] In step (2), the added amount of the solid alkali is 0.2% of the bamboo mass.

[0065] In step (2), the mass ratio of the bamboo to water is 1:4.

[0066] In step (2), the treatment temperature is 160°C.

[0067] In step (2), the treatment pressure is 0.6MPa.

[0068] Embodiment 2 of the present invention also provides an application of the method for desugaring bamboo as described above, which is used for desugaring bamboo to produce heavy bamboo boards and by-products suitable for outdoor use.

Embodiment 3

[0070] Embodiment 3 of the present invention provides a kind of bamboo desugaring method, comprises the following steps:

[0071] (1) Bamboo pretreatment: After the bamboo is rolled, it is set aside;

[0072] (2) Desugar treatment: immerse the bamboo obtained in step (1) in water, add solid alkali, and treat for 1 hour.

[0073] In step (2), the solid base is magnesium carbonate.

[0074] In step (2), the added amount of the solid alkali is 0.2% of the bamboo mass.

[0075] In step (2), the mass ratio of the bamboo to water is 1:4.

[0076] In step (2), the treatment temperature is 160°C.

[0077] In step (2), the treatment pressure is 0.6 MPa.

[0078] Embodiment 3 of the present invention also provides an application of the method for desugaring bamboo as described above, which is used for desugaring bamboo to produce heavy bamboo boards and by-products suitable for outdoor use.

Abstract

The invention relates to the technical field of bamboo processing, more specifically, the present invention relates to a bamboo desugaring method and application thereof. The invention provides a method for desugaring bamboo, which adopts solid alkali catalyzed hydrothermal desugaring treatment, which can not only realize the dissolution and hydrolysis of sugar substances in bamboo, but also can ideally retain the mechanical properties of bamboo. Moreover, the color of the bamboo after desugaring treatment is lighter, and the applicable range is wider. By adopting the bamboo material desugaring method of the present invention to carry out the desugaring treatment on the bamboo material, the sugar in the bamboo material can be fully dissolved completely, thereby effectively improving the anticorrosion and anti-mold performance of the bamboo material. At the same time, the sugar removed during the desugaring process can be collected and utilized as a by-product, turning waste into treasure and increasing the added value of bamboo processing, and there is no irritating odor during the desugaring process, which can better solve the problem of traditional desugaring. The problems encountered in the sugar treatment method have the advantages of low cost and simple process.

Description

technical field [0001] The invention relates to the technical field of bamboo processing, more specifically, the present invention relates to a bamboo desugaring method and application thereof. Background technique [0002] At present, there are two types of bamboo anti-corrosion and anti-mildew treatment methods for the production of outdoor heavy bamboo boards in the market. The first type is bamboo decomposing light carbon series, that is, after bamboo decomposing and transparent, low-temperature carbonization removes part of the sugar , add adhesive or sealant, and apply anti-mildew liquid in the late stage of plate forming to achieve the effect of anti-corrosion and anti-mold; the second type is bamboo rolling high-temperature pyrolysis series, that is, after bamboo is rolled, it passes The dry and hot air treatment on the left and right can completely degrade the organic matter in the bamboo to achieve the effect of anti-corrosion and anti-mildew. [0003] The first t...
