Problems solved by technology

The porous structure of wood itself has the effect of absorbing the peculiar smell and formaldehyde in the air, but the processing technology of the most widely used particleboard and fiberboard often needs to destroy the porous structure of wood. With the destruction of the porous structure and "trialdehyde "With the application of glue, the chip wood-based panels not only cannot absorb formaldehyde but will release formaldehyde in the adhesive

Embodiment 1

[0031] Preparation of single-layer structure tea fragrance board (the processing unit of single-layer structure tea fragrance board is a unified specification, without the distinction of surface layer and core layer)

[0032] 1) Material selection: select the tea stalks left over from the processing of Wuyishan Oolong tea leaves as processing raw materials;

[0033] 2) Material processing: In order to retain the complete porous structure of wood, the tea stems left over from oolong tea processing are cut off instead of crushed, so as to be processed into processing units with a diameter of 1-3mm and a length of 20-35mm;

[0034] 3) peeling: the processing unit is peeled, so that the bark content of the processing unit is controlled below 10% (mass content);

[0035] 4) Drying treatment: use heat conduction oil (or hot air or flue gas) as the heat source, and dry hot air generated after heat exchange as the medium, adjust the medium temperature to 145°C, and control the moistur...

[0047] Preparation of multi-layer structure tea fragrance board

[0048] 1) Material selection: select the tea stems from the matcha processing residue as processing raw materials;

[0049] 2) Material processing: In order to retain the complete porous wood structure of the wood, the tea stems left over from the matcha processing are cut off instead of crushed, so as to be processed into a surface processing unit and a core processing unit, wherein the surface processing unit has a diameter of 0.5 -2mm, the length is 15-30mm, the diameter of the core layer processing unit is 3-5mm, and the length is 30-50mm;

[0050] 3) peeling: the surface layer processing unit of step 2) is peeled, so that the bark content of the surface layer processing unit is controlled below 10% (mass content); (the materials used for the surface layer processing unit and the core layer processing unit are consistent, only different specifications)

[0051] 4) Drying: use heat conduction oil (hot air o...

Embodiment 3

[0063] Preparation of single-layer structure tea fragrance board

[0064] 1) material selection: select the remaining tea tree pruning branches of Jinguanyin Oolong tea garden as processing raw materials;

[0065] 2) Material treatment: In order to preserve the complete porous structure of the wood, the pruned branches of tea trees remaining in the Jinguanyin Oolong tea garden are cut off and cut instead of crushed, so that they are processed into specifications with a diameter of 1-3mm and a length of 20-35mm processing unit;

[0066] 3) peeling: the processing unit is peeled, so that the bark content of the processing unit is controlled below 10% (mass content);

[0067] 4) Drying treatment: use heat conduction oil (or hot air or flue gas) as the heat source, and dry hot air generated after heat exchange as the medium, adjust the medium temperature to 145°C, and control the moisture content of the processing unit at 3 %;

[0068] 5) sizing: forming a mixture of the proces...

Abstract

The invention discloses a preparation method of a direct-pressure slow-release tea fragrance environmental protection art board that releases and absorbs odor molecules, comprising: 1) material selection: selecting tea tree wood materials as processing raw materials; 2) raw material processing: cutting tea tree wood materials or cut into processing units; 3) peeling: the processing unit in step 2) is subjected to peeling treatment, so that the bark content of the processing unit is controlled below 10%; 4) drying: the processing after step 3) is processed The unit is dried; 5) glue sizing: mix the processing unit after step 4) with the E0 grade environmental protection glue, and the mass ratio of the E0 grade environmental protection glue to the processing unit is 3-4%; 6) along the core: to step 5 ) process the processing unit after processing along the core so that it is controlled in the same arrangement direction; 7) billet assembly: pave and shape the processing unit after processing the core in step 6) and age to obtain a tea slab; 7) The pre-pressing treatment, hot-pressing treatment and cooling treatment are performed on the treated tea slab base to make a tea slab.

Description

technical field [0001] The invention belongs to the field of wood-based panel manufacturing, and in particular relates to a direct-pressed tea tree wood material, a method for preparing a direct-pressed slow-release tea-flavored environmental art board (hereinafter referred to as "tea-flavored board") capable of releasing and absorbing odor molecules. Background technique [0002] Tea tree is a kind of leaf economic crop, and a large amount of waste tea tree wood materials are often treated as garbage in the production and processing of tea. In addition, there are 45 million mu of tea gardens in my country, and there are about 500,000 tons of discarded tea tree pruning branches every year. The above-mentioned tea tree wood materials are mostly used for burning, which is a great waste of resources, and burning not only pollutes the atmosphere, but also causes soil compaction. Tea has a history of 5,000 years in my country and is rich in healthy ingredients. Tea tree wood mat...
