The first step towards fire protection in nuclear power plants based on the concept of ‘Defense in-depth’ is realized through minimization combustibles. Regarding realistic methods for minimizing combustibles plants, retardancy cables as highest number should be kept design lifetime well at construction. flame test, according to IEEE-383 and IEEE-1202, was conducted assess aged unaged cables, b...

Phosphomolybdic acid (PMA) as a synergist was added into polyurethane (PU) rigid foam with ammonium polyphosphate (APP) to improve its flame retardancy and thermal stability. The combustion performance of PU studied by limiting oxygen index (LOI), UL-94, cone calorimeter. degradation behavior determined thermogravimetric analysis (TG) infrared spectroscopy (TG-IR). Experimental results showed t...

magnesium hydroxide nanostructures as an effective flame retardant were synthesized by a facile and rapid microwave reaction. the effect of different surfactants such as cationic, anionic and polymeric on the morphology of magnesium hydroxide nanostructures was investigated. nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform in...

The development of reusable fire-safe polymers with a prolonged lifetime heralds the switch for transition towards circular economy. In this framework, we report novel phosphonated thermoset which is composed networked phosphonate esters containing both PC and PO bonds. Employing simple one-pot, two-step synthetic methodology, oxirane groups epoxy resin were partially reacted various amounts re...

Paper packaging materials like cardboards are widely used to protect archives which a major kind of cultural relics. Unfortunately, paper is combustible material, and thus exploring environment-friendly flame retardant for paper-based archive material plays an important role. Herein, boric acid, borax disodium octaborate modify the craft conservation improve fire safety. The modified exhibits m...

Cost-effective and efficient sorbents with emulsion-breaking capability, especially surfactant-stabilized emulsions, are required to remediate oil spills from water. Herein, in situ growth of magnetic Mn0.01Co0.90Fe3O4 (MCFO) nanoparticles (NPs) on reduced graphene oxide (RGO) was performed prepare MCFO/RGO nanocomposite via a simple solvothermal method. The coated onto polyurethane (PU) sponge...

various morphologies of silica nanoparticles were synthesized by a microwave-assisted pechini method. silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in pechini procedure. then for preparation of polymer-matrix nanocomposites, sio2 nanoparticles were added to poly carbonate (pc) and poly...

Paraloid-Mg(OH)2 nanocomposites were synthesized via sonochemical method. Nanostructures were characterized by XRD and SEM. Thermal stability behavior of paraloid filled with magnesium hydroxide was investigated by thermogravimetric analysis (TGA). The influence of Mg(OH)2 nanostructures on the flame retardancy of the paraloid matrix was studied using UL-94 analysis. Our r...
