Abstract

一种耐压型膏状或液体炸药药柱,包括震源药柱,震源药柱主要由壳体(1)和膏状或液体炸药(2)组成;它还有耐压筒(3),耐压筒(3)放置在壳体(1)内,其筒壁上设有若干个孔(3-1),膏状或液体炸药(2)放置在壳体(1)及耐压筒(3)内。优点是:由于药柱的内装药中含有耐压空心微球,在受压环境中具有抗压力减敏作用;同时,壳体内设置有耐压筒,筒状壳体受压变形时,耐压筒可起到阻止筒状壳体变形,而使有效尺寸小于临界直径的作用,提高了药柱壳体的耐压性,以保证药柱正常起爆。

Description

一种耐压型膏状或液体炸药药柱
技术领域
在此处键入技术领域描述段落。本发明涉及炸药药柱领域。
 背景技术
在此处键入背景技术描述段落。目前,膏状或液体炸药药柱主要筒状壳体、膏状或液体炸药和雷管座(薄膜、纸筒药柱不需要雷管座)组成,膏状或液体炸药和雷管座放置在壳体内,其不足之处在于由于药柱的筒状壳体(包括塑料壳体或薄膜、纸筒)是用聚乙烯塑料加工或用薄膜、纸卷制而成,壳体壁较薄,抗压性较差,只适合用于粉状炸药,如用于膏状或液体炸药则由于其抗压性较差,在使用时,筒状壳体易受压被压瘪变形,由圆筒状变成椭圆筒状,当压瘪变形过大,其有效尺寸小于临界直径时,会导致不能起爆和传爆。
 发明内容
在此处键入发明内容描述段落。本发明的目的就是针对现有膏状或液体炸药药柱其抗压性较差之不足,而提供一种耐压型膏状或液体炸药药柱。
本发明一种耐压型膏状或液体炸药药柱,包括震源药柱,震源药柱主要由壳体和膏状或液体炸药组成;它还有耐压筒,耐压筒放置在壳体内,其筒壁上设有若干个孔,膏状或液体炸药放置在壳体及耐压筒内。
膏状或液体炸药由硝酸盐60~85%、乳化剂1~5%、油相材料3~6%和水5~10%经乳化加工后,再外加空心微球0.2~3%混匀制成,百分比为重量百分比。
耐压筒为圆筒状、椭圆筒状、方筒状或多棱筒状。
耐压筒可由网筒代替。
耐压筒的抗压强度要大于0.3MPa。
本发明的优点是:由于药柱的内装药中含有耐压空心微球,在受压环境中具有抗压力减敏作用;同时,壳体内设置有耐压筒,筒状壳体受压变形时,耐压筒可起到阻止筒状壳体变形,而使有效尺寸小于临界直径的作用,提高了药柱壳体的耐压性,以保证药柱正常起爆。
 附图说明
附图1为本发明结构示意图。
附图2为网管式耐压筒结构示意图。
具体实施方式
如图所示;在现有的药柱壳体(包括塑料壳体或薄膜、纸筒,直径62mm)1内放置耐压筒3,耐压筒3用高强度PVC塑料制成(直径40mm,壁厚2.5mm),其直径和长度略小于壳体1,在耐压筒筒壁上开若干个均匀分布的圆孔(直径20mm)3-1,耐压筒通过孔3-1与壳体1相通。耐压筒3也可用网筒(见图2,筒壁上的孔为网状)。膏状或液体炸药2放置在壳体1及耐压筒3内。膏状或液体炸药由硝酸盐60~85%、乳化剂1~5%、油相材料3~6%和水5~10%经乳化加工后,再外加空心微球0.2~3%混匀制成。耐压筒3为圆筒状。耐压筒3的抗压强度要大于0.3MPa。
