新型纳米级HL抗冻剂对岩石水胶炸药抗冻性能的影响实验

在组分和制备工艺完全一致的情况下,研究了添加新型纳米级HL抗冻剂对水胶炸药抗冻性能的影响作用。将水胶炸药试验样品在-20℃下冷冻24小时后测试其作功能力,用作功能力大小表征试样的抗冻性能。对比了水胶炸药试样添加该抗冻剂前后的抗冻性能,研究了添加不同量的抗冻剂对水胶炸药试样抗冻性能的影响。结果表明,在该抗冻剂添加量达到4%之后,水胶炸药的抗冻性能得到明显提高,且随着该抗冻剂添加量的增加水胶炸药的抗冻性能先增后降,呈现出近似抛物线型变化趋势,其最佳添加量为8%⁹%。

STUDY ON THE IMPACT OF THE NEW NANO-HL ANTIFREEZE AGENT ON THE FROST-RESISTANCE OF THE ROCK WATER-GEL EXPLOSIVE

Under completely identical condition of the water-gel explosive component and preparation process,the impact of the new nano-HL antifreeze agent on the frost-resistance of the water-gel explosive was studied.The working capacity of the water-gel explosive samples were tested after frozen 24 hours in-20℃,the frost-resistance was characterized by the working capacity.The frost resistance of the watergel explosive samples before and after added the antifreeze agent and with different content were tested.The results showed that the performance of the water-gel explosive had been significantly improved after the content of the antifreeze agent reached to 4%.The frost resistance of the water-gel explosive first increased and then decreased as the antifreeze agent increasing,and it showed approximate parabolic pattern and the optimal content of the antifreeze agent was 8%9%。Under completely identical condition of the water-gel explosive component and preparation process,the impact of the new nano-HL antifreeze agent on the frost-resistance of the water-gel explosive was studied.The working capacity of the water-gel explosive samples were tested after frozen 24 hours in-20℃,the frost-resistance was characterized by the working capacity.The frost resistance of the watergel explosive samples before and after added the antifreeze agent and with different content were tested.The results showed that the performance of the water-gel explosive had been significantly improved after the content of the antifreeze agent reached to 4%.The frost resistance of the water-gel explosive first increased and then decreased as the antifreeze agent increasing,and it showed approximate parabolic pattern and the optimal content of the antifreeze agent was 8%⁹%.
