Embodiment 1

[0023] The production method of the recombined bamboo sliced ​​veneer in this example is:

[0024] 1) Manufacture of bamboo strips: process bamboo into bamboo material, and then cut it into bamboo sections; cut the bamboo sections into bamboo pieces, and then put the bamboo pieces into the cooking pool for 4 hours, remove the bamboo green from the treated bamboo pieces, and the remaining Part of the bamboo strips are made into bamboo strips with a length of 1900mm, a width of 1.0mm, and a thickness of 6mm after being thickened and then rolled and combed; the bamboo strips are not allowed to have defects such as greening, yellowing, insect eyes, mildew, rotten strips, and tender strips;

[0025] 2) Carbonization and drying of bamboo strips: put the prepared bamboo strips into a carbonization tank, the carbonization temperature is 135°C, and the carbonization time is 3 hours; then dry the carbonized bamboo strips at a temperature of 80°C until the moisture content is about 10% ;...

Embodiment 2

[0035] The production method of the recombined bamboo sliced ​​veneer in this example is:

[0036] 1) Manufacture of bamboo strips: process bamboo into bamboo material, and then cut it into bamboo sections; cut the bamboo sections into bamboo pieces, then put the bamboo pieces into the cooking pool for 6 hours, remove the bamboo green from the treated bamboo pieces, and the remaining Part of the bamboo strips are made into bamboo strips with a length of 2530mm, a width of 1.5mm, and a thickness of 6mm after being thickened and then rolled and combed; the bamboo strips are not allowed to have defects such as green, yellow, insect eyes, mildew, rotten strips, and tender strips;

[0037] 2) Drying of bamboo strips: The bamboo strips after decompression are bundled into piles and stacked in a drying room for drying at a drying temperature of 65°C until the moisture content is 10%;

[0038] 3) Impregnation and drying of bamboo strips: immerse the dried bamboo strips in phenolic res...

Embodiment 3

[0047] The production method of the recombined bamboo sliced ​​veneer in this example is different from Example 1: the 3200mm long bamboo strips are made into 3200×100×100mm bamboo squares after dipping, hot pressing and other processes; the bamboo squares are pressurized and water injected , the impregnation pressure is 1.5MPa, and the time is 12h, so that the moisture content of the bamboo timber reaches more than 25%; then it is boiled and softened, the heating rate is controlled at 2°C / min, the temperature is 70°C, and the softening time is 72h; the obtained length is 3200mm , a width of 290mm, a thickness of 0.6mm carbonized recombined bamboo sliced ​​veneer products. The rest are the same as Example 1.

Abstract

The invention relates to a manufacturing method of a recombined bamboo sliced veneer and aims to provide a simple-production and low-cost manufacturing method of the combined bamboo sliced veneer. Adopting bamboo splits to substitute for bamboo chips saves bamboo planning capacity and greatly improves bamboo utilization rate. The manufacturing method includes steps of 1) manufacturing the bamboo splits; 2) drying or carbonizing the bamboo splits; 3) impregnating and drying the bamboo splits; 4) shaping and processing the bamboo splits; 5) punching square timber of the bamboo splits; 6) dipping and conditioning the square timber of the bamboo splits; 7) softening the square timber of the bamboo splits; 8) slicing the square timber of the bamboo splits; 9) post processing.

Description

technical field [0001] The invention relates to a method for manufacturing recombined bamboo sliced ​​veneer, which belongs to the field of wood-based panels and bamboo processing, and is mainly used for wood-based panels, furniture, interior decoration and the like. Background technique [0002] Bamboo is a good substitute for wood. In my country, where forest resources are scarce, bamboo processing has a broad space for development. At present, in the manufacturing industry of slicing thin bamboo and thin bamboo decorative materials, the bamboo used is generally taken according to the length of the bamboo board; when manufacturing rectangular bamboo pieces, the thickness is determined based on the small end of the bamboo blank. for processing. This traditional method of retrieving materials has a large amount of cutting and a low utilization rate of bamboo. Chinese patent document CN1227102C discloses "a kind of slicing thin bamboo and its production method", Chinese pat...
