Research reveals sodium alginate-based fire-retardant gel shows improved thermal stability and rheological behaviour, suggesting effective fire prevention strategies.
Key Points
The aim is to develop and characterize a bio-based flame-retardant gel using sodium alginate and evaluate its performance.
Utilized sodium alginate as the matrix for flame-retardant gels.
Incorporated ammonium polyphosphate and phytic acid for enhanced flame resistance.
Modified surfaces with SiO2-APTES for improved interaction.
Investigated effects of N/P molar ratio on gel's properties and performance.
Optimal N/P ratio of 1/4 enhanced shear stress by 33%.
Peak heat release rate reduced by 10%, indicating better fire resistance.
Total smoke production decreased by 75%, showcasing reduced toxicity.
Char layer thickness increased by 150% after combustion, indicating effective thermal stability.
