Round bamboo grading method

Abstract

The invention provides a round bamboo grading method. The round bamboo grading method comprises the steps that the diameter at the breast height and the basic density of a plurality of round bamboo samples are measured; and according to the diameter at the breast height and the basic density of the multiple round bamboo samples, a K-mean cluster analysis algorithm is adopted, and diameter stage grading and density grading are carried out on round bamboos. According to the round bamboo grading method, the diameter stage grading and density grading are carried out on the round bamboos, the processing scheme and purposes of the round bamboos are determined according to different diameter grade sizes and densities, the round bamboos low in density and small in diameter grade can be used for manufacturing non-structural materials for floors, furniture, decoration and the like, and the round bamboos high in strength can be used for manufacturing structural materials for bridges and building components. The round bamboos with the same density stage are selected as raw materials for manufacturing a plate or structural wood, the designability and even performance of the materials can be achieved, and the round bamboo products stable in quality are researched and developed. Meanwhile, the reasonable machining scheme is determined according to the different diameter stages, the moso bamboo using rate is improved by 5%, and the maximum round bamboo application value is achieved.

Description

technical field [0001] The invention relates to the field of bamboo applications, in particular to a method for grading round bamboo. Background technique [0002] my country is the center of the origin of bamboo in the world, ranking first in the world in terms of bamboo species, area, stock volume, and annual harvesting volume, and the output of moso bamboo accounts for more than 2 / 3 of my country's total bamboo output. Bamboo has a strong ability to regenerate, and can complete high growth within 2-4 months, and the bamboo can be used sustainably in one-time afforestation. Round bamboo has high strength, good toughness, and high hardness. Wood is widely used in construction, home furnishing and other fields. [0003] Today, with the rapid development of the bamboo industry, bamboo strip-laminated lumber, bamboo laminated lumber, and recombined bamboo are produced by using round bamboo units of different sizes. However, the distribution of moso bamboo in China is widespr...
