高活性铝粉燃烧热测试及其影响因素分析
|
摘要
为对高活性铝粉的燃烧热进行准确可靠的测量,使用氧弹量热仪,采用GAP作为助剂,通过多次实验研究了助剂种类及添加比例、充气气氛及压力等测试条件对铝粉燃烧热测试结果的影响,确定了最佳的实验测试参数,并采用助剂法测定了50、100、200 nm铝粉的燃烧热。结果表明,使用GAP作为助剂,选择1∶4(质量比)混合制样,在O_2气氛充气压力1.5 MPa条件下,高活性铝粉具有最高的燃烧效率,且随着高活性铝粉粒度的增大,其燃烧热值减小,燃烧效率降低。
The combustion heat of highly reactive nanometer aluminum( n Al) was measured in an Oxygen-bomb calorimeter.The GAP binder was served as accessory ingredient. The influence of test conditions such as type and proportion of additive ingredients and atmosphere pressure in the bomb was studied experimentally. The combustion heats of n Al with different particle sizes(50 nm,100 nm,200 nm) were tested. The results show that the highly reactive n Al presents the highest combustion efficiency by using GAP as an additive with the mass ratio of 1 ∶ 4 and choosing the condition of O_2 atmosphere under the pressure of 1.5 MPa.The test data also indicate that combustion efficiency decrease with the increase of particle size.
