Nyob rau hauv ib puag ncig thoob ntiaj teb niaj hnub no, cov phaj tiv thaiv mos txwv (lossis cov vuas tiv thaiv mos txwv) yog cov neeg muaj nqis heev, tab sis ntawm kev ua lag luam ntawm cov phaj tiv thaiv mos txwv muaj ntau yam, qhov sib txawv ntawm kev ua tau zoo kuj loj heev, raws li cov khoom siv, cov txheej txheem thiab lwm yam phaj tiv thaiv mos txwv feem ntau tuaj yeem muab faib ua peb pawg, uas yog cov phaj hlau tiv thaiv mos txwv, polyethylene PE tiv thaiv mos txwv thiab cov phaj tiv thaiv mos txwv ceramic, peb hom phaj tiv thaiv mos txwv txhua tus muaj qhov zoo thiab qhov tsis zoo, Kev xaiv kuj xav tau kev txiav txim siab dav dav. Xaiv cov phaj tiv thaiv mos txwv, yuav tsum tsom mus rau peb yam ntxwv yog qhov hnyav, tus nqi thiab lub peev xwm tiv thaiv mos txwv (uas yog qib tiv thaiv mos txwv), hnub no peb yog los ntawm peb yam no ntawm peb hom phaj tiv thaiv mos txwv kev tshuaj xyuas thiab kev sib piv.
1. Phaj hlau tiv taus mos txwv
Cov phaj hlau tiv thaiv tau mos txwv tau siv txij li Tsov Rog Thoob Ntiaj Teb Zaum Ob thiab tau tswj hwm kev lag luam tiv thaiv tau mos txwv ntau xyoo dhau los. Tab sis tom qab kev tsim cov phaj polyethylene PE tiv thaiv tau mos txwv thiab cov phaj ceramic tiv thaiv tau mos txwv, cov phaj hlau tiv thaiv tau mos txwv tau maj mam hloov. Lawv tseem siv niaj hnub no, tab sis tsawg dua.
Piv nrog rau daim phaj tiv thaiv mos txwv tshiab, daim phaj hlau tiv thaiv mos txwv yooj yim tawg tom qab raug tua, uas yuav ua rau lub cev tib neeg puas tsuaj thib ob. Piv nrog rau ob yam khoom siv, daim phaj hlau tiv thaiv mos txwv uas muaj tib theem kev tiv thaiv hnyav dua, siv zog ntau dua thiab txo qhov yooj ywm ntawm tus neeg hnav.
Txawm hais tias lub phaj hlau tiv taus mos txwv yog tus nqi qis tshaj plaws hauv peb lub ntxig, tab sis feem ntau, nws tsis pom zoo kom ua qhov kev xaiv thawj zaug.
2. Polyethylene PE phaj tiv thaiv tau mos txwv
Polyethylene PE yog ib hom khoom siv thermoplastic tshiab. Polyethylene PE daim phaj tiv thaiv mos txwv yog tsim los ntawm kev sib txuas cov polyethylene fibers ultra-high molecular weight rau ntawm lub rooj tsavxwm polyethylene siab. Nws raug txiav ua duab, muab tso rau hauv pwm, thiab nias rau hauv qhov kub thiab txias siab kom tau txais daim phaj tawv tawv. Cov polyethylene "lo rau" lub mos txwv los ntawm kev yaj cov polyethylene vim kev sib txhuam los ntawm lub mos txwv tig. Thaum lub sijhawm tig tsis ua haujlwm, tsis muaj cua sov tshwm sim, thiab cov polyethylene txias thiab rov khov dua.
Qhov zoo ntawm polyethylene PE bulletproof phaj feem ntau yog li 1 txog 1.5kg, sib dua li cov hlau bulletproof phaj thiab ceramic bulletproof phaj. Txawm li cas los xij, vim muaj kev txwv ntawm cov txheej txheem khoom siv tam sim no, PE ntshiab phaj tuaj yeem ua tiav qib kev tiv thaiv siab tshaj plaws ntawm NIJ III, tsis tuaj yeem tiv thaiv cov mos txwv piercing thiab cov mos txwv muaj zog dua, thiab tus nqi siab ntawm polyethylene PE, nws tus nqi feem ntau kim dua 200% txog 300% dua li ceramic bulletproof phaj, tsis yog qhov kev xaiv zoo.
3. Phaj tiv thaiv kab mob ceramic
Cov khoom siv ceramic siv tau ntau yam khoom siv, feem ntau yog alumina, silicon carbide thiab boron carbide. Cov khoom siv ceramic tiv taus mos txwv vim lawv qhov kev tawv, lub zog, thiab tshuaj lom neeg tsis muaj zog hauv ntau qhov chaw. Nws zoo dua li hlau vim tias cov khoom siv hlau yuav tsim cov yas deformation thiab nqus lub zog thaum tiv taus qhov cuam tshuam ntawm lub taub hau warhead, thaum ceramic yuav tsis tshua tsim cov yas deformation thiab lub taub hau warhead yuav blunt lossis txawm tawg vim nws tus kheej lub zog siab thiab cov yam ntxwv tawv. Cov khoom siv ceramic tiv taus mos txwv thiab lub zog siab fiber ntau modulus composite phaj txheej bulletproof, thaum lub projectile ceev ceev thiab txheej ceramic sib tsoo, cov txheej ceramic tawg lossis tawg thiab mus rau qhov cuam tshuam ua qhov chaw nruab nrab rau ib puag ncig kom siv feem ntau ntawm lub zog ntawm lub cev projectile, tom qab ntawd cov phaj fiber ntau modulus composite kom siv cov zog seem ntawm lub cev projectile ntxiv. Yog li ntawd, kev siv cov khoom siv ceramic siab heev hauv cov txheej txheem armor yog qhov zoo heev thiab tau dhau los ua cov cuab yeej tiv thaiv dav dav rau cov cuab yeej armor, tsheb, dav hlau thiab lwm yam khoom siv.
Qhov tsis zoo ntawm cov phaj ceramic yog tias tom qab raug ntaus, qhov chaw cuam tshuam tsis tuaj yeem tiv thaiv lub mos txwv dua. Tab sis tam sim no cov phaj ceramic sib dua thiab muaj zog dua li yav dhau los, qee cov chaw tsim khoom tuaj yeem ua rau nws qhov hnyav ze rau PE phaj, thiab los ntawm kev siv cov ntaub ntawv sib txawv kuj tuaj yeem ua tau raws li qhov hnyav, tus nqi thiab lwm yam kev xav tau.
Hauv qhov loj me tib yam nrog tib theem kev tiv thaiv, cov phaj ceramic bulletproof yog sib dua li cov phaj steel bulletproof, thiab tus nqi qis dua li polyethylene PE phaj thiab txawm tias qhov tuab tuaj yeem nyias dua.
Feem ntau, cov hlau bulletproof phaj yog yooj yim thiab pheej yig, tab sis qhov hnyav loj dhau, thiab yooj yim ua rau muaj kev puas tsuaj thib ob rau tus neeg siv; Txawm hais tias polyethylene PE bulletproof phaj yog lub teeb, tab sis lub peev xwm bulletproof tsis zoo, thiab tus nqi kim; Piv rau hais lus, ceramic bulletproof phaj tsis tsuas yog lub teeb zoo, tus nqi qis, thiab lub peev xwm bulletproof zoo heev; kev ua tau zoo ntawm silicon carbide ceramic bulletproof phaj yog ntau dua ntawm alumina phaj, yog qhov kev xaiv zoo tshaj plaws ntawm bulletproof phaj.
