Alcoxisilanos glicosilados-quitosano, en la conservación de materiales constructivos silíceos y calcáreos de bienes inmuebles históricos
Bibliographic record
Abstract
Resumen En este estudio, se han sintetizado hibridos alcoxisilanos-quitosano, empleando como silanos el THEOS (tetrakis(2-hidroxietoxi)silano) y del MeTHEOS (tris(3-hidroxietoxi)metil silano. Se propone el uso de estos compuestos en el campo de la conservacion de materiales petreos constructivos de naturaleza silicea y calcarea de edificaciones arquitectonicas y arqueologicas de importancia historica patrimonial. Una caracteristica de esta propuesta es el empleo de agua como vehiculo de aplicacion, asi como resolver el problema de la interaccion entre alcoxisilanos y materiales calcareos. Palabras clave: alcoxisilano, quitosano, conservacion arquitectonica, THEOS ABSTRACT In the search of other silicon derivatives with potential use in stone conservation, we suggest the use of tetrakis(2-hydroxyethyl) silane (THEOS) and tris(2-hydroxyethyl) methyl silane (MeTHEOS) as water soluble precursors. Additionally , it is already known THEOS is compatible with different natural polysaccharides as chitosan and the same behavior has been observed for MeTHEOS. The hybrids obtained are used as consolidants and hydrophobic formulations as water soluble silanes in the conservation of historical building materials siliceous and calcareous. Having in mind the required evaluation, several chemical and physical analysis have been performed in order to assessing the effectiveness and compatibility of the suggested hybrids on carbonate and silicate substrates. Key words: alkoxysilanes, chitosan, architectural conservation, THEOS

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.
