卡腰对导爆管雷管延时精度的影响?

摘要：  
通过改变雷管的卡腰尺寸和卡腰位置来探究卡腰对雷管延时精度的具体影响。试验研究表明，卡腰工艺会影响延期体的燃烧速度和燃烧稳定性，对于相同的延期体结构，卡腰尺寸越大，燃烧速度越快，气体堵塞效应越小，燃烧越稳定，雷管延时精度越高；当其他所有条件一致，雷管的卡腰位置由延期体上端移到延期体底端时，延期体的燃速变慢，受气体压力影响更小，燃烧更稳定，雷管延时精度更高；此外，当卡腰尺寸或卡腰位置变化时，药芯直径的大小会影响雷管延时精度的改变幅度。
Abstract：  
Influence of middle chucking on delay accuracy of the detonator was studied by changing size and position of middle chucking. Results show that combustion rate and combustion stability of the delay element are affected by the middle chucking technique. With the same structures of the delay element, the larger the middle chucking size, the faster the combustion rate;then, the smaller the jam effect of gas, the more stable the combustion, and the higher the accuracy of delay detonator. With all the same other conditions, when the middle chucking is moved from the top to the bottom of the delay element, combustion rate of the delay element becomes slower and the gas pressure inflection is smaller, so that it could have a more stable combustion and higher delay accuracy. In addition, while the size or position of middle chunking changes, amplitude of the delay accuracy would be affected by the core diameter.
