红锥木材性质与UF胶固化时间关系的研究

对红锥木材性质与UF胶固化时间的测定和分析结果表明：红锥木材呈弱酸性，心边材不同部位、树干不同高度木粉的pH值和缓冲容量无显著差异；UF胶的固化时间与pH值在0．01水平上相关极显著，与酸缓冲容量在0．05水平上相关显著，与碱缓冲容量相关不显著。研究结果为红锥木材的培育和合理利用提供了科学依据。

Studies on the Relationship between Castanopsis hystrix Wood Properties and Curing Time of UF

Castanopsis hystrix wood properties and curing time of UF were determined and analyzed, the results showed that Castanopsis hystrix wood showed a little acid property, the pH value and buffering capacity was no significant differences in the difference position of sapwood and heartwood, and was no significant differences in the difference altitude of trunk; the curing time of UF was very significantly related to the pH value at 0 01 level, was significantly related to the acid buffering capacity at 0 05 level, and was no related to the alkali buffering capacity. The conciusions provide scientific basis for plantation cultivation and rational utilization of Castanopsis hystrix wood.
