Modification of <i>Pinus sylvestris</i> L. wood with quat- and amino-silicones of different chain lengths
Bibliographic record
Abstract
Abstract The water-related properties of Scots pine ( Pinus sylvestris L.) sapwood have been improved by treatment with quat- and amino-silicones of different chain lengths. Standard leaching test and hot water Soxhlet extraction (6 h) showed that the amino-silicones are better fixed in wood than the quat-silicones. A water dipping test (24 h) revealed that both quat- and amino-silicones made wood hydrophobic; however, amino-silicones were more effective in reducing water uptake. The long-chained silicones of both types resulted in higher water repellent effectiveness compared with the respective short-chained silicones. As demonstrated by assessing cell wall bulking, scanning electron microscopy (SEM), and SEM energy-dispersive X-ray analysis, silicones with short chains penetrated the cell wall better than those with long chains regardless of the silicone type. The maximum antishrink efficiency of approximately 60% was attained with short-chained amino-silicone at approximately 39% weight percent gain. The short-chained silicones show more potential to enhance the water-related properties of solid wood and for the development of silicone-based industrial wood modification processes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
