Masiku ano apadera apadziko lonse lapansi, mbale za Bulletproof (kapena matailosi otetezedwa ndi zipolopolo) amayamikiridwa kwambiri ndi anthu, koma pamsika wa mbale ya bulletproof ndi yamitundumitundu, kusiyana kwa magwiridwe antchito ndikwambiri, malinga ndi zinthu, ndondomeko ndi mbale zina zomwe ziwopsezo zipolopolo zimatha kugawidwa. m'magulu atatu, mbale zitsulo zipolopolo, polyethylene PE chipolopolo mbale ndi ceramic zipolopolo mbale, mitundu itatu ya mbale zipolopolo aliyense ali ndi ubwino ndi kuipa, kusankha kumafunanso kuganizira mozama.Sankhani mbale yotchinga zipolopolo, muyenera kuyang'ana kwambiri pazifukwa zitatu zomwe ndi kulemera, mtengo ndi kuthekera koletsa zipolopolo (zomwe ndi mulingo wa bulletproof), lero tikuchokera ku mbali zitatu izi za mitundu itatu ya kusanthula ndi kufananitsa mbale za zipolopolo.
1. Mbale yachitsulo yosalowa zipolopolo
Zitsulo zoteteza zipolopolo zakhala zikugwiritsidwa ntchito kuyambira Nkhondo Yachiwiri Yapadziko Lonse ndipo zinkalamulira msika wotetezedwa ndi zipolopolo zaka makumi angapo zapitazo.Koma pambuyo chitukuko cha polyethylene PE chipolopolo mbale ndi ceramic mbale zipolopolo, zitsulo mbale zipolopolo pang'onopang'ono m'malo.Amagwiritsidwabe ntchito masiku ano, koma m'mawerengero ang'onoang'ono.
Poyerekeza ndi mbale yatsopano yotchinga zipolopolo, mbale yachitsulo yoteteza zipolopolo ndiyosavuta kuthyoka ikaomberedwa, zomwe zingawonongenso thupi la munthu.Poyerekeza ndi zipangizo zina ziwiri, mbale yachitsulo yotetezedwa ndi zipolopolo zomwe zili ndi mlingo wofanana wa chitetezo zimakhala zolemera, zimadya mphamvu zambiri komanso zimachepetsa kusinthasintha kwa wovala.
Ngakhale mbale zitsulo zipolopolo ndi mtengo otsika mu kuika atatu, koma zonse, si bwino ngati kusankha woyamba.
2. Polyethylene PE bulletproof mbale
Polyethylene PE ndi mtundu watsopano wa zinthu za thermoplastic.Polyethylene PE bulletproof mbale amapangidwa pomanga unidirectional ultra-high molecular kulemera polyethylene ulusi pa mkulu kachulukidwe polyethylene bolodi.Amadulidwa mumpangidwe, amaikidwa mu nkhungu, ndi kuponderezedwa pansi pa kutentha kwakukulu ndi kukakamizidwa kuti apeze mbale ya zida za viscous zolimba.Polyethylene "imamatira" pachipolopolo posungunula polyethylene chifukwa cha kukangana komwe kumachitika chifukwa cha kuzungulira kwa chipolopolocho.Kuzungulirako kukasiya, palibe kutentha komwe kumapangidwa, ndipo polyethylene imazizira ndikuumitsanso.
Ubwino wa mbale ya polyethylene PE bulletproof nthawi zambiri imakhala pafupifupi 1 mpaka 1.5kg, yopepuka kwambiri kuposa mbale yachitsulo yosakanizidwa ndi zipolopolo ndi mbale ya ceramic bulletproof.Komabe, chifukwa cha zofooka za ndondomeko panopa zinthu, koyera PE mbale akhoza kukwaniritsa mlingo wapamwamba chitetezo cha NIJ III, osatha kuteteza ku mfuti kuboola zipolopolo ndi zipolopolo zamphamvu kwambiri, ndi kukwera mtengo wa polyethylene PE, mtengo wake nthawi zambiri 200. % mpaka 300% okwera mtengo kuposa mbale ya ceramic bulletproof, si chisankho chabwino.
3. Ceramic bulletproof mbale
Zoyika za ceramic zimatha kugwiritsa ntchito zinthu zosiyanasiyana, zofala kwambiri ndi alumina, silicon carbide ndi boron carbide.Ma Ceramics ndi opanda zipolopolo chifukwa cha kuuma kwawo kwakukulu, mphamvu, ndi kusakhazikika kwamankhwala m'malo ambiri.Ndi bwino kuposa zitsulo chifukwa zipangizo zachitsulo zimatulutsa mapulasitiki apulasitiki ndikuyamwa mphamvu pokana kukhudzidwa kwa mutu wa nkhondo, pamene ceramic sichidzatulutsa mapulasitiki apulasitiki ndipo mutuwo udzakhala wosasunthika kapena wosweka chifukwa cha mphamvu zake zazikulu ndi kuuma kwake.Bulletproof ceramic ndi high high modulus fiber composite plate bulletproof wosanjikiza, pamene projectile yothamanga kwambiri ndi kugunda kwa ceramic wosanjikiza, kugawanika kwa ceramic layer kapena kung'ambika ndikufika pamalo okhudzidwa ndi malo ozungulira kuti awononge mphamvu zambiri za projectile body, ndiye mbale yapamwamba ya modulus fiber composite kuti iwononge mphamvu yotsalira ya thupi la projectile.Chifukwa chake, kugwiritsa ntchito zida zadothi zapamwamba mu zida zankhondo ndizowoneka bwino kwambiri ndipo zakhala zida zodzitetezera zomwe zimagwiritsidwa ntchito kwambiri pazida zankhondo, magalimoto, ndege ndi zida zina.
Kuipa kwa mbale ya ceramic ndikuti pambuyo pa kugunda, malo okhudzidwa sangathe kuteteza chipolopolocho kachiwiri.Koma tsopano mbale ya ceramic ndi yopepuka komanso yamphamvu kuposa kale, opanga ena amatha kupanga kulemera kwake pafupi ndi mbale ya PE, ndipo pogwiritsa ntchito zipangizo zosiyanasiyana akhoza kukwaniritsa kulemera kwake, mtengo ndi zofunikira zina.
Mu kukula komweko ndi mulingo womwewo wachitetezo, mbale ya ceramic bulletproof ndiyopepuka kuposa mbale yachitsulo yopinga zipolopolo, ndipo mtengo wake ndi wotsika kuposa mbale ya polyethylene PE ndipo ngakhale makulidwe ake amatha kukhala ochepa.
Kawirikawiri, mbale yachitsulo yachitsulo ndi yosavuta komanso yotsika mtengo, koma kulemera kwake ndi kwakukulu, komanso kosavuta kuwononga yachiwiri kwa wogwiritsa ntchito;Ngakhale mbale ya polyethylene PE bulletproof ndi yopepuka, koma luso lachipolopolo ndi losauka, ndipo mtengo wake ndi wokwera mtengo;Poyerekeza, mbale ya ceramic bulletproof mbale osati kuwala kokha, mtengo wotsika, ndi luso la zipolopolo ndi zabwino kwambiri;Magwiridwe a mbale ya silicon carbide ceramic bulletproof mbale ali pa alumina mbale, ndiye chisankho chabwino kwambiri cha mbale yoletsa zipolopolo.
