Abstract
It is generally known that anionic trash in pulp slurry has a negative impact in any process where cationic polymer is used. In the peroxide bleaching of triploid populus tomentosa carr. CTMP, the formation of anionic trash is mainly due to the dissolution of polygalacturonic acid, oxidized lignin and fatty and resin acid. The amount of the anionic trash depends on the brightness target. Two factors affecting the formation of anionic trash were investigated in this paper. The results showed that NaOH charge was the most important factor affecting the formation of anionic trash in the peroxide bleaching process of triploid populus tomentosa carr. CTMP. On the other hand, the H_2O_2 charge mainly affected the formation of lignin-bound anionic trash. The result also indicated that the dissolution of the oxidized lignin was one of the main sources of the anionic trash generated in the process of the peroxide bleaching of triploid populus tomentosa carr. CTMP.

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 it
