Problems solved by technology

The bamboo board removes the hardest bamboo green on the bamboo, and at the same time, the surface layer of the formed material is opposite to the original surface layer of the original bamboo, so the surface layer of the bamboo board is relatively hard. The internal stress of the plate is large, and the formed material will be deformed due to the internal stress after a long time, which needs to be improved

Embodiment 1

[0043] Embodiment 1: a kind of manufacture method of bamboo fiber bamboo board, comprises the following steps:

[0044] (1) Preprocessing:

[0045] a. Arranging the original bamboo into trunks, branches and leaves for subsequent use;

[0046] b. Bamboo stems are classified according to the size of the tube diameter and the thickness of the bamboo belly, and then sawn into sections, and cut into 2-6 arc-shaped bamboo slices, with a width of 1-15cm;

[0047] c. Remove dead, worm and necrotic parts of branches and leaves, and break the normal growing parts into bamboo silk powder;

[0048] (2) Indirect heating with steam or hot air or high-frequency electric wave or microwave treatment for heat treatment of bamboo chips and bamboo silk powder:

[0049] Carbonize the arc-shaped bamboo slices and bamboo silk powder at 80°C-200°C and 1.5-3.5MPa carbonization pressure for 2-4 hours or cook at 80°C-200°C under normal pressure for 2-4 hours;

[0050] (3) Remov...

Embodiment 2

[0057] Embodiment 2: According to the needs of customers, the bamboo boards made in Embodiment 1 are made into bamboo floors, outdoor floors, and bamboo decorative boards of various specifications.

Abstract

The invention discloses a manufacturing method for a bamboo fiber bamboo board. The manufacturing method is characterized in that bamboo green is not required to be removed, and is only slightly sanded, and bamboo tubes are split, thermally treated and flattened, so that an original surface layer of bamboo is a surface layer of a formed material, the surface layer strength of the bamboo board is strengthened, and the original performance of the bamboo is fully utilized to improve original ecological features; and in addition, a bamboo chip is fully crushed to form a reticular fiber connecting shape, and internal stress release slots are formed in a bamboo inner skin surface and a bamboo green surface, so that a scientific channel is provided for the release of internal stress of the formed material in a using process, and the stability of the formed material during use is ensured.

Description

technical field [0001] The invention relates to a method for processing bamboo into a high-strength bamboo board. technical background [0002] Traditional bamboo flooring is made by cutting, opening small pieces and then bonding and pressing. The utilization rate of bamboo flooring is less than 60%. Also Chinese patent application 200610021013.2 discloses a "processing method of carbonized high-density bamboo", which processes bamboo into bamboo slices, removes the green layer and dead yellow layer, and splits the bamboo slices into bamboo threads or grinds them into vertically and horizontally connected large pieces. Bamboo shreds, put the bamboo shreds or bamboo shreds in a carbonization tank, under the pressure of 2~3MPa, 100~300℃, thermally decompose and carbonize for 2-3 hours, soak the pyrolytic carbonized bamboo shreds or bamboo shreds Glue, and then the soaked bamboo strips or bamboo strips are cured in the mold after high pressure to form a material. The bamboo b...
