| 摘 要： | 本文分析研究了3种沙生灌木的构造和酸碱特性。研究结果表明：①3种灌木材的纤维形态较好，纤维含量高，是生产纸浆、纤维板和刨花板的优质原料。②3种灌木材均呈弱酸性，pH值在5．27－5．48之间，酸性接近；3种灌木材总缓冲容量在0．469mmol-0.494mmol之间，其中酸缓冲容量在0．026mmol-0.028mmol之间，碱缓冲容量在0.441mmol-0.468mmol之间；脲醛树酯胶固化时间随3种灌木材的pH值和减缓容量的增加而增长。

| Abstract: | The structure and properties (pH,acid and alkali bufferigcapacity,the effect on the setting time of UF)of three species shrubs were studied.It showed that fiber morphology of three species shrubs good and content of cellulose is high.So they are excellet material for pulp、fiber board and shaving board,the three kinds of shrub are of weak acidity(pH:5.27-5.48).Their acidity is similar.The acid alkali buffering capacity is 0.469-0.494mmol,acid buffering capacity is 0.026-0.028mmol and alkali buffering capacity is 0.441-0.468 mmol.The setting time of UF increases with the increase of wood pH and alkali buffering capacity. |
