| 中文摘要: |
| 本文研究了空心玻璃微珠添加量及泡沫液浓度对泡沫灭火剂发泡能力和稳定性的影响,对比了热辐射条件下空心玻璃微珠添加前后泡沫的热稳定性。结果表明,添加量低于40%时,空心玻璃微珠对泡沫灭火剂发泡能力影响不大,而泡沫的稳定性显著降低,添加量为50%时,虽泡沫发泡能力降低,但泡沫的稳定性却增强。泡沫的发泡能力随蛋白泡沫浓度升高而增强。蛋白浓度为10%,空心微珠添加量为50%时,由于泡沫内部形成了稳定的三相泡沫骨架结构,泡沫热稳定性较未添加微珠之前显著增强。 |
| 英文摘要: |
| In this paper,by comparing the stability of fire fighting foam before and after adding the hollow microsperes under heat radiation,the effect of the hollow microsperes on the foamability and stability of fire fighting foam were tested.The result showed that the stability of fire fighting foam was improved after adding 50% of hollow glass microsperes,though the foaming ability decreased.The stability of fire fighting foam increased obviously with the addition of 50% of hollow microsperes and 10% of fire fighting protein,due to formation of a stably three-phase frameworks inside the protein froth intermixture. |
