在采用压缩空气引火仪做气体压燃实验的过程中,合理选用燃烧剂,是保证实验成功的重要因素。常用的燃烧剂有乙醚、硝化棉、混合药棉、火柴头药等。由于这些燃烧剂在制作、保存和使用等方面的诸多因素,给实验带来了许多不方便,有时甚至会使实验不易成功。在对多种燃烧剂进行使用、比较的基础上,我们改用脱脂棉粘上少量凡士林做燃烧剂,实验效果相当明显,且制作、保存和使用都很方便。具体做法是,取绿豆大小的脱脂棉一粒粘
In the process of gas compression ignition experiment using compressed air pilot instrument, reasonable choice of combustion agent is an important factor to ensure the success of the experiment. Commonly used combustion agents include ether, nitrocellulose, mixed cotton wool, and match head medicine. Due to many factors in the production, preservation and use of these combustion agents, many inconveniences have been brought to the experiment, sometimes even making the experiment less successful. Based on the use and comparison of various kinds of combustion agents, we changed the use of absorbent cotton and a small amount of vaseline as the combustion agent. The experimental results are quite obvious, and it is convenient to make, save and use. The specific approach is to take a green bean-sized cotton wool sticky
