Application of MCA–AlPi Nitrogen–Phosphorus Synergistic Flame Retardant in Nylon 11

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: April 15, 2025

ABSTRACT Halogen‐free flame‐retardant nylon was prepared by melting a mixture of 11 (PA11), melamine cyanurate (MCA) and aluminum diethylphosphonate (AlPi) in twin‐screw extruder. The addition amount ratio the synergistic formula would affect effect degradation process composites. In cone calorimetric test, when content 35%, total heat release (THR) halogen‐free decreased 24% to 52% compared with pure PA11. most noteworthy finding is that ignition time (TTI) MCA (334 s) significantly longer than PA11 (131 AlPi (140 formulas, compound can be better single‐component formula, up 404 s. Upon analyzing structure composition gas products char residue each we discerned played different roles promoting formation carbon residues within condensed phase. Based on all test results, it concluded mechanism nitrogen involves delaying decomposition composites an expanded layer generating refractory gas.

MOF-Enhanced Aluminosilicate Ceramic Membranes Using Non-Firing Processes for Pesticide Filtration and Phytochrome Removal

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(11), P. 944 - 944

Published: May 27, 2024

Aluminosilicates, abundant and crucial in both natural environments industry, often involve uncontrollable chemical components when derived from minerals, making further purification reaction more complicated. This study utilizes pure alumina fumed silica powders as controllable sources, enhancing aluminosilicate reactivity through room temperature (non-firing) processing providing a robust framework that resists mechanical stress high temperature. By embedding iron-based metal–organic frameworks (Fe-MOF/non-firing membranes) within the above matrix, these ceramic membranes not only preserve their robustness but also gain significant functionality, capacity to removing phytochromes vegetables. Sodium hydroxide sodium silicate were selected activators successfully prepare high-strength, non-firing membranes. These demonstrated flexural strength of 8.7 MPa under wet-culture conditions with molar ratio Al2O3:SiO2:NaOH:Na2SiO3 at 1:1:0.49:0.16. The chlorophyll adsorption spinach conducted on showed removal rate exceeding 90% pH = 9, highlighting its potential for selective chlorophyll. underscores MOF-enhanced environmental applications, particularly agricultural pollution control.
