- Abstract
Absorption differences of the two British softwood species, Corsican pine (Pinus nigra var. maritima (Ait.) Melville) and Sitka spruce (Picea sitchensis (Bong.) Carr.), were examined on the basis of (i) sapwood and heartwood, and (ii) the three structural directions of sapwood under the same treatment condition of the fullcell process (i.e. 640 mmHg vacuum and 6 bar pressure for 5 minutes). Accordingly, conclusions on indication of the flow characteristics are listed separately for the general purpose of the work on account of the percentage of void volume filled by tanalith-C: (i) Significant differences between the two species within a set of triple flow on sapwood and heartwood. The penetration of sapwood was much greater than that of heartwood, although Corsican pine was more readily treated according to Sitka spruce in either zones. (ii) Very highly significant differences among the three structural directions in both species showing the descending order of the fluid absorption as longitudinal>tangential>radial, although in that any cases Corsican pine was much more permeable than in Sitka spruce.
