This article aims to explain the relationship of ammonium phosphate content and extinguishing ability. The fire extinguisher, dry chemical, certification system, fire extinguishing mechanism and verification methods are explained, and experiment results are discussed. The fire extinguishing time of the high-performance fire extinguisher with high ammonium phosphate content is less than half that of conventional fire extinguisher in the B-7 model. Furthermore, the fire extinguisher with high ammonium phosphate content can extinguish the B-14 model in 7.5 seconds. However, the conventional fire extinguisher fails to extinguish the B-14 test. It is suggested that increasing the content of ammonium phosphate in the power extinguishing agent greatly improved its fire extinguishing effect.
