摘　　要：在市售以磷酸二氢铵为灭火基料的ABC干粉灭火剂中加入氢氧化镁,利用自制实验装置对干粉灭火剂进行灭火性能、灭火温降实验测试。实验结果表明:氢氧化镁含量低于10%时,灭火剂灭火性能没有改善;氢氧化镁含量为20%时,干粉灭火效率、灭火后温降速率明显提高。Magnesium hydroxide was added to the ABC dry-powder extinguishingant using ammonium dihydrogen phosphate as the basic material on the market. Self-made experiment apparatus was established to test the fire extinguishing performance and temperature decrease rate of the extinguishingant. The experiment shows when the content of the magnesium hydroxide is lower than 10 %, the fire extinguishing performance doesn＇t change; but when the content raises to 20 %, the fire extinguishing rate and temperature decrease rate increase dramatically.
