消焰剂降低枪口火焰的研究

选择了硫酸钾、硝酸钾、新型钾盐AK和BK四种不同结构性能的消焰剂,采用在钝感和包覆时加入的两种添加工艺制备出装药样品。通过B门照相法测试了枪口火焰,进行了消焰剂影响降低枪口火焰的试验研究。结果表明,同种消焰剂不同的添加工艺对降低枪口火焰作用不同,钝感时加入消焰剂对降低枪口火焰作用大,而包覆时加入消焰剂对降低枪口火焰作用小。与常规消焰剂硫酸钾、硝酸钾相比较,新型钾盐AK和B K吸湿性小,在相同含量相同添加方式下消焰效果好。同种消焰剂相同添加方式下含量越高,消焰效果越好。

Research of Reducing the Muzzle Flame by Flame Inhibitor

Four kinds of flame inhibitors with different structure and functionalities,K2SO4,KNO3,new potassium salts AK and BK were selected and the powder charge samples were made using two patterns of adding flame inhibitors in desensitiged and coated course. The muzzle flames were tested with a B-shutter photography method. The effects of flame inhibitor on muzzle flame were experimentally studied. Results show that different adding patterns of the same flame inhibitors have different effect on reducing flame. The effects on reducing flame when adding in the desensitiged course are better than that in the coated course. The new potassium salts AK and BK are not hygroscropic and have better effect on reducing muzzle flame than the common flame inhibitors,K2SO4 and KNO3. Under the conditions of same inhibitor and adding pattern,the more flame inhibitor adds,the better effect on muzzle flame reduces.
