Mejoramiento de la Tenacidad de Polipropileno con nanopartículas de Carbonato de Calcio
Bibliographic record
Abstract
Las propiedades mecánicas de nanocompuestos de polipropileno (PP) con carbonato de calcio (CaCO3) fueron estudiados en este trabajo. Se utilizó ácido esteárico como un nuevo modificador de interfaz durante la preparación de los nanocompuestos utilizando una extrusora de doble husillo. La concentración en peso del nanorelleno (CaCO3) en los compuestos fue de 1,5 %, 2,5 % y 5,0 %, respectivamente. Se hicieron caracterizaciones a los nanocompuestos de resistencia al impacto y ensayos de tracción. La interacción entre CaCO3 y ácido esteárico se analizó mediante FTIR. Los espectros de infrarrojo no mostraron ninguna reacción química entre CaCO3 y ácido esteárico. El alargamiento a la rotura y la resistencia al impacto se incrementaron en los nanocompuestos utilizando un modificador de interfaz (ácido esteárico en la tolva de la extrusora)

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
