Abstract
Due to the bad adhesivity between explosive powder and shock tube, the shock tube tends to be broken and the shock detonator sometimes misfires. According to the theory of blending modification and oriented molecule migration , a series of special dedicated plastics for shock tube with high adhesivity were designed. For the need of adhesivity between explosive powder and shock tube during transmission, the best formula with 16. 0% expulsion rate of explosive powder was determined. Experimental results showed that in contrast with conventional N210 and 1I2A counterparts, the highly adhesive shock tube has decreased the number of broken holes to 0 per 15m after shock (4 holes for N210 and 2 holes for 1I2A) , broken holes at 50℃ to 0 per 15m (4 holes per 15m for N210 and 2 holes per 15m for 1I2A) and mifire rate of 0 (10% for N210 and 6% for 1I2A).关键词
