Nyob rau niaj hnub no lub ntiaj teb tshwj xeeb ib puag ncig, Bulletproof phaj (los yog mos mos mos mos vuas) muaj nuj nqis heev los ntawm cov neeg, tab sis nyob rau hauv kev ua lag luam ntawm mos mos phaj yog multifarious, kev ua tau zoo sib txawv kuj loj heev, raws li cov khoom, txheej txheem thiab lwm yam bulletproof phaj yuav muab faib. rau hauv peb pawg, xws li steel bulletproof phaj, polyethylene PE mos txwv phaj thiab ceramic bulletproof phaj, peb hom mos txwv phaj txhua tus muaj qhov zoo thiab qhov tsis zoo, Qhov kev xaiv kuj yuav tsum muaj kev xav zoo.Xaiv cov mos txwv phaj, yuav tsum tau tsom mus rau peb tus cwj pwm yog qhov hnyav, tus nqi thiab lub peev xwm ntawm cov mos txwv (xws li cov mos txwv qib), hnub no peb yog los ntawm peb yam ntawm peb hom mos txwv phaj tsom xam thiab kev sib piv.
1. Hlau phom phom phaj
Hlau phom phom phaj tau siv txij li Kev Tsov Rog Thoob Ntiaj Teb thib 2 thiab tau tuav lub khw muag khoom phom sij ntau xyoo dhau los.Tab sis tom qab kev txhim kho ntawm polyethylene PE mos txwv phaj thiab ceramic bulletproof phaj, steel bulletproof phaj tau maj mam hloov.Lawv tseem siv niaj hnub no, tab sis tsawg dua.
Piv nrog rau cov tshiab phom phom phaj, cov hlau phom phom phaj yog ib qho yooj yim tawg tom qab raug tua, uas yuav ua rau muaj kev puas tsuaj rau tib neeg lub cev.Piv nrog rau ob qho khoom siv, cov hlau phom phom phaj nrog tib theem ntawm kev tiv thaiv hnyav dua, siv zog ntau dua thiab txo qhov hloov pauv ntawm cov neeg hnav.
Txawm hais tias cov hlau phom phom phaj yog tus nqi qis tshaj plaws hauv peb qhov ntxig, tab sis tag nrho, nws tsis pom zoo ua thawj qhov kev xaiv.
2. Polyethylene PE mos txwv phaj
Polyethylene PE yog ib yam tshiab ntawm cov khoom siv thermoplastic.Polyethylene PE bulletproof phaj yog tsim los ntawm kev sib txuas unidirectional ultra-siab molecular hnyav polyethylene fibers mus rau high-density polyethylene board.Nws raug txiav rau hauv cov duab, muab tso rau hauv pwm, thiab compressed nyob rau hauv kub thiab siab kom tau ib tug viscous nyuaj armor phaj.Cov polyethylene "sticks" rau cov mos txwv los ntawm melting polyethylene vim kev sib txhuam los ntawm cov mos txwv txoj kev sib hloov.Thaum qhov kev sib hloov nres, tsis muaj cua sov tsim, thiab polyethylene txias thiab rov ua dua.
Qhov zoo ntawm polyethylene PE bulletproof phaj feem ntau yog li ntawm 1 txog 1.5kg, ntau dua li cov phom phom phom phom phaj thiab ceramic bulletproof phaj.Txawm li cas los xij, vim muaj kev txwv ntawm cov txheej txheem khoom siv tam sim no, ntshiab PE phaj tuaj yeem ua tiav qhov kev tiv thaiv siab tshaj plaws ntawm NIJ III, tsis tuaj yeem tiv thaiv cov phom phom tho thiab cov mos txwv muaj zog dua, thiab tus nqi siab ntawm polyethylene PE, nws tus nqi feem ntau yog 200. % mus rau 300% kim tshaj li ceramic mos txwv phaj, tsis yog qhov kev xaiv zoo.
3. Ceramic bulletproof phaj
Ceramic inserts tuaj yeem siv ntau yam ntaub ntawv, ntau dua yog alumina, silicon carbide thiab boron carbide.Ceramics yog mos txwv vim lawv qhov tshwj xeeb nruj, lub zog, thiab tshuaj lom neeg inertness hauv ntau qhov chaw.Nws yog qhov zoo dua li cov hlau vim tias cov ntaub ntawv hlau yuav tsim cov yas deformation thiab nqus lub zog thaum tiv thaiv qhov cuam tshuam ntawm lub taub hau, thaum ceramic yuav tsis tshua tsim cov yas deformation thiab lub taub hau yuav blunt lossis txawm tawg vim nws lub zog siab thiab hardness yam ntxwv.Bulletproof ceramic thiab siab zog siab modulus fiber composite phaj bulletproof txheej, thaum lub high-ceev projectile thiab cov ceramic txheej sib tsoo, ceramic txheej fragmentation los yog tawg thiab mus rau qhov cuam tshuam taw tes raws li qhov chaw mus rau ib puag ncig kom haus feem ntau ntawm lub zog. projectile lub cev, ces lub siab modulus fiber composite phaj mus ntxiv noj cov residual zog ntawm lub cev projectile.Yog li ntawd, daim ntawv thov ntawm advanced ceramics nyob rau hauv armor systems yog heev txaus nyiam thiab tau los ua ib tug dav siv tiv thaiv armor rau lub cev armor, tsheb, aircraft thiab lwm yam khoom siv.
Qhov tsis zoo ntawm cov phaj ceramic yog tias tom qab raug ntaus, qhov cuam tshuam tsis tuaj yeem tiv thaiv cov mos txwv dua.Tab sis tam sim no cov phaj ceramic yog sib dua thiab muaj zog dua li yav dhau los, qee cov tuam ntxhab tuaj yeem ua kom nws qhov hnyav ze rau PE phaj, thiab los ntawm kev siv cov khoom sib txawv tuaj yeem ua tau raws li qhov hnyav, tus nqi thiab lwm yam yuav tsum tau ua.
Nyob rau hauv tib qhov loj nrog tib theem ntawm kev tiv thaiv, ceramic bulletproof phaj yog sib dua li steel bulletproof phaj, thiab tus nqi qis dua polyethylene PE phaj thiab txawm lub thickness yuav thinner.
Feem ntau, cov hlau phom phom phaj yog qhov yooj yim thiab tus nqi qis, tab sis qhov hnyav yog qhov loj heev, thiab yooj yim rau kev puas tsuaj rau cov neeg siv;Txawm hais tias polyethylene PE mos txwv phaj yog lub teeb, tab sis lub peev xwm ntawm cov mos txwv tsis zoo, thiab tus nqi yog kim;Piv txwv li, ceramic bulletproof phaj tsis yog lub teeb zoo, tus nqi qis, thiab muaj peev xwm tiv thaiv tau 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 cov mos txwv phaj.
