suppressant

To overcome the limitations of the present powder suppressants in the suppression of coalmine gas explosion,explosion suppression experiments on nanometer powder were carried out in the self-improved 20-liter spherical experimental system.

针对目前粉体抑爆剂抑制矿井瓦斯爆炸的局限性,采用自主改进的20 L近球型瓦斯抑爆实验系统进行纳米粉体的抑爆实验。

The effect of explosion suppression with traditional suppressant was analyzied.

通过对传统抑爆剂抑制瓦斯爆炸的作用分析,自主改进形成了瓦斯抑爆实验系统,采用最大爆炸压力、压力上升平均速率等指标表征纳米粉体的抑爆性能。
