正拱形爆破片分類：

正拱普(pu)通型(xing)爆(bao)(bao)破(po)片(pian)（LP）結構特點：正拱形爆(bao)(bao)破(po)片(pian)，凹(ao)面處于壓(ya)力系統高壓(ya)側。正拱普(pu)通型(xing)爆(bao)(bao)破(po)片(pian)為單層爆(bao)(bao)破(po)片(pian)，壓(ya)力高時拱殼(ke)壁厚減薄而被拉(la)伸(shen)破(po)壞，也稱為拉(la)伸(shen)型(xing)爆(bao)(bao)破(po)片(pian)。

正拱普通型爆(bao)破(po)片安裝在壓(ya)(ya)(ya)力(li)設備上后，在正常的工作壓(ya)(ya)(ya)力(li)下，不在發(fa)生顯著的塑性變形(xing)，這(zhe)是由于(yu)(yu)其預拱成形(xing)壓(ya)(ya)(ya)力(li)一般大于(yu)(yu)其工作壓(ya)(ya)(ya)力(li)，爆(bao)破(po)片在工作壓(ya)(ya)(ya)力(li)下處于(yu)(yu)彈性狀(zhuang)態。

 正(zheng)(zheng)拱(gong)(gong)開(kai)縫型(xing)爆(bao)(bao)(bao)(bao)破(po)片（LF）結構特點 ：正(zheng)(zheng)拱(gong)(gong)形爆(bao)(bao)(bao)(bao)破(po)片，凹面處于(yu)壓(ya)力(li)(li)系統高壓(ya)側。爆(bao)(bao)(bao)(bao)破(po)片由兩層或兩層以上組成，且其(qi)中一(yi)層為(wei)密(mi)封(feng)膜，并至少有(you)一(yi)層為(wei)帶有(you)孔(縫)的正(zheng)(zheng)拱(gong)(gong)形爆(bao)(bao)(bao)(bao)破(po)片。正(zheng)(zheng)拱(gong)(gong)開(kai)縫型(xing)爆(bao)(bao)(bao)(bao)破(po)片是為(wei)了解決(jue)爆(bao)(bao)(bao)(bao)破(po)壓(ya)力(li)(li)小(xiao)或泄(xie)放口徑很小(xiao)時(shi)生產困難(nan)的一(yi)種(zhong)新結構，為(wei)使其(qi)密(mi)封(feng)，必須加(jia)設密(mi)封(feng)膜，由于(yu)密(mi)封(feng)膜材料受溫度和壓(ya)力(li)(li)的限制(zhi)，使正(zheng)(zheng)拱(gong)(gong)開(kai)縫型(xing)爆(bao)(bao)(bao)(bao)破(po)片的適用范圍(wei)收(shou)到(dao)了限制(zhi)。

正拱帶(dai)槽(cao)型爆破片（LC）結構特點(dian)：正拱形爆破片，凹面處于壓(ya)力系統高壓(ya)側(ce)。爆破片上加工有(you)減(jian)弱槽(cao)的正拱形爆破片。

正(zheng)拱(gong)(gong)帶槽型爆(bao)破(po)(po)片(pian)(pian)（LC）在一(yi)定程度上克(ke)服(fu)了正(zheng)拱(gong)(gong)普通(tong)型爆(bao)破(po)(po)片(pian)(pian)和正(zheng)拱(gong)(gong)開縫型爆(bao)破(po)(po)片(pian)(pian)的(de)(de)缺(que)點(dian)，爆(bao)破(po)(po)壓(ya)力主要取(qu)決于(yu)減(jian)弱槽的(de)(de)強(qiang)度，因此調節減(jian)弱槽的(de)(de)剩余厚(hou)度，就可(ke)以改變其爆(bao)破(po)(po)壓(ya)力，但壓(ya)力較低時在制造上會產(chan)生困(kun)難。正(zheng)拱(gong)(gong)帶槽型爆(bao)破(po)(po)片(pian)(pian)的(de)(de)特點(dian)是(shi)，爆(bao)破(po)(po)后(hou)不(bu)產(chan)生碎片(pian)(pian)。

正拱形爆破片分類參數介紹：操(cao)作比為(wei)70%及以上，抗疲勞強度要優于平板(ban)形爆破(po)片(pian)。適用(yong)于液相(xiang)、氣相(xiang)和(he)氣液兩(liang)相(xiang)介質，相(xiang)配(pei)夾持器型(xing)號為(wei)LJ型(xing)夾持器。
