通过对龙竹、甜龙竹、黄竹和油勒竹4种云南村用丛生竹主要物理力学性质的检测分析认为,其饱湿含水率、气干密度、绝干密度和基本密度随竹种和秆高部位的不同而差异显著,但气干含水率、饱湿密度的差异不大;干缩率特别是径向干缩率随竹种不同而显著有异,但与竹秆部位无明显关系;径向干缩率大于弦向干缩率,竹青端的弦向干缩率大于竹黄端的弦向干缩率;顺纹抗压强度和弦向抗弯强度的竹秆部位差异较竹种间的差异为大.上述差异的存在是确定以丛生竹为原料的各种竹人造板的结构、生产工艺和成品质量的重要依据.
Based on the analysis of the main physical and mechanical properties of the bamboo species of four species of bamboo in Yunnan Province, such as Longzhu, Sweet Dragon, Huangzhu and Olea chinensis, the results showed that the moisture content, dry air density, And stem height of the difference is significant, but the air-dry moisture content, wet density difference is not big; shrinkage rate, especially the radial shrinkage rate varies significantly with the bamboo species, but with no significant part of the bamboo The radial shrinkage was greater than that of chord, while the chord shrinkage at the green end was greater than that at the end of bamboo. The difference is large. The existence of these differences is to determine the bamboo bamboo as raw material for a variety of bamboo wood-based panel structure, production technology and quality of the finished product important basis.
