Nano-TiO_2 Modified Polyvinyl Chloride for Improving Resistance to Ultraviolet Illumination
Bibliographic record
Abstract
The property and feature of P(MMA-BA)/TiO2 nano-composites were studied with FT-IR,1H-NMR,and UV-Vis.PVC/P(MMA-BA)/TiO2 composites were prepared by melt-blending process.It was shown that nano-sized rutile TiO2 is PVC/P(MMA-BA) copolymer;there is strong interaction between nano-sized rutile TiO2 and PVC/P(MMA-BA).PVC and PVC/P(MMA-BA)/TiO2 composites were degraded by 1032 h accelerated aging test with exposure to fluorescence ultraviolet light lamp.It was shown that,with the UV shielding capability of nano-sized rutile TiO2,the ageing resistance of PVC have been improved,the service life of PVC have been prolonged.

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.
