摘要

在此,我们研究了由蛤壳和稻壳制备的纳米硅酸钙(nCa2SiO4),将其用作包括ABC干粉的灭火混合物中的化学剂。对A类和B类火灾的灭火性能进行了评估。基于不同的参数,即灭火时间、灭火剂用量、火灾温度降低率、燃料上的粉末涂层和再燃事件,将制备的混合物与商业磷酸一铵粉末进行了比较。研究发现,nCa2SiO4和ABC干粉的混合物分别能在10.67和9s内扑灭A类和B类火灾,而商业磷酸一铵粉末分别需要11s和11.33s才能扑灭A类和B类火灾。因此,与商业磷酸一铵粉末(仅B类)相比,nCa2SiO4和ABC干粉的混合物更有效,消耗更少。本研究证明了nCa2SiO4在提高干粉灭火器性能方面的功效。

Performance improvement of the dry chemical-based fire extinguishers using nanocalcium silicate synthesised from biowaste
Herein, we investigated nanocalcium silicate (nCa2SiO4) prepared from clam shells and rice husks for its utilisation as a chemical agent in a fire-extinguishing mixture comprising ABC dry powder. The fire-extinguishing performance was evaluated with Class A and B fires. The prepared mixture was compared with commercial mono-ammonium phosphate powder based on different parameters, namely extinguishing time, amount of extinguishing agent used, fire temperature reduction rate, powder coating on the fuel and a reburn incident. It was found that the mixture of nCa2SiO4 and ABC dry powder could extinguish Class A and B fires within 10.67 and 9 s, respectively, while commercial mono-ammonium phosphate powder required 11 and 11.33 s to extinguish Class A and B fires, respectively. Thus, the mixture of nCa2SiO4 and ABC dry powder was more effective and less consumed as compared to commercial mono-ammonium phosphate powder (Class B only). This study demonstrates the efficacy of nCa2SiO4 to improve the performance of dry chemical-based fire extinguishers.

期刊介绍: The Journal of Fire Sciences is a leading journal for the reporting of significant fundamental and applied research that brings understanding of fire chemistry and fire physics to fire safety. Its content is aimed toward the prevention and mitigation of the adverse effects of fires involving combustible materials, as well as development of new tools to better address fire safety needs. The Journal of Fire Sciences covers experimental or theoretical studies of fire initiation and growth, flame retardant chemistry, fire physics relative to material behavior, fire containment, fire threat to people and the environment and fire safety engineering. This journal is a member of the Committee on Publication Ethics (COPE).
