Bulletproof iav zoo li qhov qub, tab sis nws tsis tawg rau ntawm kev cuam tshuam, thiab yog tias koj tua ntawm nws, lub mos txwv yuav tsis tawg ntawm lub iav zoo li no, nws yuav nyam nws. Nws tsis yooj yim sua los ua mos txwv iav ntawm koj tus kheej, vim nws yog cov txheej txheem kev lag luam ntau, tab sis nws txaus siab heev los kawm seb nws tshwm sim li cas.
Qhov tsim muaj ntawm daim tsom iav
Lub tswv yim uas koj tuaj yeem ntxiv dag zog rau iav los ntawm kev ua rau nws ua rau nkag mus rau hauv lub siab ntawm Fabkis tus kws tshawb fawb Edouard Benedictus hauv xyoo 1910. Nws tau los nrog lub tswv yim ntawm kev tso zaj duab xis celluloid nruab nrab ntawm ob daim ntawv ntawm iav, uas cuam tshuam ntau zog ntawm lub zog ntawm cov khoom lag luam. Niaj hnub no hom no hu ua "lamination" ntawm iav, thiab Benedictus ib zaug hu nws "Triplex".
Tam sim no, tib lub thev naus laus zis tau siv, tab sis nws tau zoo dua qub txij thaum ntawd, thiab hloov cov celluloid, siv ntau hom polymers siv. Qee lub sij hawm khoov iav yog txawm glued ua ke. Khoov lawv ua ntej sib txuas.
Ua mos txwv iav hnub no
Cov mos txwv qhov tsom iav tuaj hauv lub thicknesses sib txawv, nws nyob ntawm qhov no seb lub khob yuav nws thiaj li nres lub mos txwv. Lub tuab ntawm cov tsom iav zoo li ntawm 7 hli txog 75 hli. Niaj hnub no, feem ntau feem ntau ua cov nplai iav, ntau txheej ntawm zoo tib yam yog siv, nruab nrab ntawm cov khaubncaws sab nraud povtseg twg polycarbonate tau nchuav. Polycarbonate yog cov pob tshab yas thiab nws hnyav heev, albeit laminated. Thaum lub mos txwv nkag mus rau qhov tuab ntawm lub khob ntawm no, cov txheej txheem txuas ntxiv ntawm polycarbonate nqus nws lub zog, thiab nws nres.
Tam sim no, kev hloov kho tshwj xeeb ntawm cov ntom ntom iav uas ua tau - ib-sab. Kev siv hom yas tshwj xeeb, siv cov yam ntxwv sib txawv, nyob ntawm kev coj ua dab tsi los cuam tshuam nrog nws. Ib sab ntawm xws iav nres cov mos txwv, tab sis yog tias koj tua los ntawm lwm sab ntawm iav, koj tuaj yeem ntaus tus yeeb ncuab. Qhov no tso cai rau cov neeg tom qab lub khob tuaj yeem tuaj yeem tiv thaiv kev tawm tsam. Nyob rau tib lub sijhawm, iav saum npoo khoov yam tsis tas yuav tsoo.
Iav lamination
Lub lamination ntawm iav (thov zaj duab xis yas rau nws) yog cov txheej txheem nyuaj heev los ntawm cov txheej txheem kev xav. Nws yog ua rau ntawm cov cuab yeej siv dav, hauv ntau theem. Qhov kawg theem siv qhov chaw ntawm qhov kub thiab txias, zaj duab xis yas polymerizes thiab tau txais kwv yees li cov khoom qub xws li cov kua nplaum ntawm cov ntawv ua haujlwm. Nws yog lub sijhawm no tias lub tsom iav tau txuas nrog thaum kawg.
Txawm hais tias bulletproof iav yog qhov ruaj heev, tsis muaj lub iav zoo meej. Qhov cuam tshuam lub zog ntawm laminated iav yog li 15 npaug siab tshaj qhov uas zoo tib yam ntawm daim iav tiaj tiaj. Tab sis txawm hais tias xws li daim ntawv raug rhuav tshem, cov tawg tsam yuav nyob hauv zaj duab xis, thiab yuav tsis ya hauv txhua qhov kev qhia, ua rau tib neeg raug mob.
Peb-txheej bulletproof iav yog suav tias yog qhov zoo tagnrho rau kev tsim khoom. Qhov laj thawj yog tias nrog txhua txheej txheej tshiab, tsis yog tsuas yog cov khoom pov thaiv nce ntxiv, tab sis kuj yuav tsum tau cov nqi ntawm iav ntau lawm. Laminated iav yog siv rau hauv qhov xwm txheej loj heev uas muaj kev hem thawj rau tib neeg lub neej lossis hauv tsev cia puav pheej tiv thaiv cov khoom pov thawj kim heev.
