Abstract
This article investigates the foaming process of bi-cellular polystyrene foams blown with n-butane and water in extrusion. The bi-cellular foam structure has two types of cells: large cells ranging from 0.1 to 1.2 mm and small cells ranging in size from about 5% to about 50% of the average large cell size, which constitute more than 90% of the total cell volume. A bi-cellular structure has outstanding heat insulation property. In order to generate a bi-cellular structure, a water-blowing technology was used. This technique is environmentally benign and economical since butane and water are used as blowing agents. Despite these advantages, the foaming process and mechanism of bi-cellular foams have not been identified in detail. Therefore, in this article, an attempt has been made to enhance our knowledge and understanding of the foaming behavior of bi-cellular polystyrene foam. The effects of n-butane, water, and silica (a nucleating agent) on the foam cell morphology are presented.

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
