A kind of arc split bamboo chip and preparation method thereof

Abstract

The invention discloses split arc bamboo chips and a manufacturing method thereof. Bamboo wood of a large diameter serves as a raw material, a bamboo strip with a bamboo outer layer and tabasheer is obtained after the procedures of cutting, outer section removal, bamboo tube splitting and inner section removal, the outer arc radius of the bamboo strip is measured through a radius measuring instrument, the radius of an arc cutter is calculated according to the radius of an outer arc of the bamboo strip and the thickness of the bamboo chips, the arc cutter is selected according to a calculation result, the bamboo strip is chopped into the bamboo chips with arc sections and a uniform radial thickness in the longitudinal direction, wherein the bamboo chips are parallel to the outer surface of the bamboo strip, then hot press is conducted on the arc bamboo chips, and the bamboo chips are flattened and milled to be provided with rectangular sections. According to the split arc bamboo chips, the bamboo outer layers are reserved on parts of the bamboo chips, the bamboo chips can be used for producing bamboo ply wood of bamboo laminated wood and the like with the bamboo chips serving as basic materials, processing amount can be reduced, energy consumption is saved, and the utilization rate of the bamboo can be improved. The split arc bamboo chips also can be used for producing the bamboo laminated wood with the bamboo outer layers. The surfaces of produced plates are smooth, the thickness is uniform, deformation is small, natural and attractive appearance of the bamboo outer layers is maintained, and a good decorative effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of bamboo wood-based panel production, and in particular relates to an arc-shaped split bamboo chip and a preparation method thereof. Background technique [0002] my country is rich in bamboo resources, and the bamboo forest area, bamboo species and economic utilization level rank first in the world, and it is known as the "Kingdom of Bamboo". There are about 100 genera and more than 1,200 species of bamboo in the world. In my country, there are 39 genera and more than 500 species. Among them, 16 genera and more than 200 species have been cultivated and utilized because of their high economic and ecological value. Bamboo is a natural fast-growing material that has a similar texture to wood, and my country is rich in bamboo resources. Rational development and utilization of bamboo building materials can alleviate the contradiction between domestic timber supply and demand, and has very important economic, so...
