專業c型聚能管聚能包由炸、形罩、隔板、殼體、引信和支架等部分組成，其作用及對聚能包威力的影響分述如下。1．炸，炸是聚能管爆破的能源，炸的爆壓越大，聚能彈威力越大；為得到高爆壓，需高爆速、高密度的炸。常用炸有梯恩梯、8321炸等，裝方法有熔鑄，塑裝和壓裝多種。2．型罩，型罩的作用是把炸的爆炸能轉化成罩體材料的射流動能，從而提高其穿透和切割能力。c型聚能管價格型(xing)(xing)(xing)罩(zhao)(zhao)的材料必須(xu)滿足四點(dian)要求，即(ji)可壓縮性(xing)(xing)小(xiao)、密度高(gao)、塑性(xing)(xing)和(he)(he)延展性(xing)(xing)好，在形(xing)成射流中(zhong)不汽化(hua)。大(da)量試(shi)驗證明，用(yong)紫銅制(zhi)作型(xing)(xing)(xing)罩(zhao)(zhao)效果好，其(qi)次為鑄鐵(tie)、鋼和(he)(he)陶瓷。型(xing)(xing)(xing)罩(zhao)(zhao)的形(xing)狀多種多樣，主(zhu)要有軸(zhou)(zhou)對(dui)(dui)稱(cheng)型(xing)(xing)(xing)，如圓錐形(xing)、半球形(xing)、拋物線形(xing)和(he)(he)喇叭形(xing)等；面對(dui)(dui)稱(cheng)型(xing)(xing)(xing)，常見(jian)的有用(yong)于切(qie)割(ge)屬板材的直線形(xing)和(he)(he)用(yong)于切(qie)割(ge)管材的環形(xing)聚(ju)能罩(zhao)(zhao)兩種；中(zhong)心(xin)(xin)對(dui)(dui)稱(cheng)型(xing)(xing)(xing)，這(zhe)種球形(xing)聚(ju)能包，中(zhong)心(xin)(xin)有球形(xing)空腔和(he)(he)球形(xing)罩(zhao)(zhao)，球形(xing)罩(zhao)(zhao)外敷設(she)炸(zha)，若能在瞬(shun)間同時起爆，可在空腔中(zhong)心(xin)(xin)點(dian)獲得極大(da)的能量集中(zhong)。在工(gong)程(cheng)中(zhong)常用(yong)的是(shi)軸(zhou)(zhou)對(dui)(dui)稱(cheng)型(xing)(xing)(xing)和(he)(he)面對(dui)(dui)稱(cheng)型(xing)(xing)(xing)兩類(lei)型(xing)(xing)(xing)罩(zhao)(zhao)。
