Embodiment Construction

[0016] Material selection: according to the volume, the bark whose volume is in the form of a solid is prepared separately according to the size of 3×3mm-400×400mm. Small particles can be placed in a concentrated manner, blocks can be placed to avoid weight accumulation, and scattered to keep the blocks from breaking shall prevail.

[0017] Softening treatment: put the selected massive bark in 10% sodium carbonate or other alkaline solutions for cooking, the cooking temperature is 80-120°C, and the cooking time is generally about 1.5 hours.

[0018] The water content of the bark after softening treatment is relatively high, and it should be dried to a water content of 8-10% before being transferred to collage. The drying method can be natural ventilation drying or hot air drying at around 40-80°C.

[0019] Material selection and cutting: Cut the part of the bark with a volume of 20×20mm-400×400mm in contact with the spliced ​​base plate to make it smooth.

Abstract

The technological process of producing composite plate of spliced bark includes the following steps: sorting bark material, softening, cold pressing of bark and spliced board or hot splicing and curing, ageing, mechanical forming and trimming, sanding, dedusting, etc. During the production process, 10 % concentration alkali solution is added to speed the softening of bark, and eliminate partial starch and saccharide for preventing moth, and the ageing step can moisten bark mutually and volatile partial water. The composite plate of spliced bark made with waste bark as main material has certain strength, tight combination, low cost, natural bark grains and other advantages.

Description

technical field [0001] The invention relates to a production process of a composite board, in particular to a composite process of bark and board. Background technique [0002] The patent application whose publication number is CN1309033 discloses a method for making the surface of decorations with birch bark. The method first carries out shaping and cutting of birch bark, puts it into boiling water for 2.5-3.5 hours, and then dries it. After the stamping process is formed, the collage is glued on the surface of the decoration. The birch bark technology is only applicable to this tree species, and cannot process all types of bark, which has limitations. The boiling water softening method has an effect on birch bark with a thinner thickness, but cannot be applied to other thicker bark softening or the effect is not good. It belongs to the surface paving material, and its application range and form are single. [0003] The patent application whose publication number is CN12...
