通过试验可知,抽提方法和水抽提工艺对尾巨桉木材的白度与色差呈极显著性影响,而用1%NaOH和苯/醇抽提其抽提时间和浴比对尾巨桉木材白度与色差的影响显著,且当木材抽提物抽出量增大时,木材的白度和色差呈规律性变化。可以通过采取适当的抽提工艺来控制抽出量,通过抽出量来控制漂白的白度与色差。
Experiment showed that extractive methods and technology had evident effect on white content and chromatic aberration of Eucalyptus grandis × E. urophylla timber. They could be controlled by the quantity of extractives with proper extractive technology.
