摘要:本研究采用水上升置换气流法测定了长白鱼鳞云杉木材渗透性,并利用苯-乙醇对其进行浸提处理,探明浸提物对渗透性的影响及改善其渗透性的可能性。试验结果表明,长白鱼鳞云杉气干心材的气体渗透性为0.02872达西(darcy),属渗透性低、浸注难树种;苯-乙醇浸提对其心材气体渗透性的影响高度显著,浸提后渗透性得到明显改善,渗透性平均增加75%,而且可以增加渗透的均匀性。
The axial gas permeability of the air-dried heartwood of refractory spruce (Picea jezoensis var. Komarovii) was measured with rising-water volume-displacement method and the effect of benzene-ethanol extraction upon it was studied. The results indicated that the axial gas permeability, of the spruce air-dried heartwood is 0.02872 darcy and benzene-ethanol extraction pretreatment not only increases the permeability of it by 75%, but also improves its uniformity.
