Los ntawm ancient sij hawm mus rau niaj hnub lub sij hawm, lub hauv paus ntawm tag nrho cov tub rog kev ua ub no nyob ib ncig ntawm ib tug tseem ceeb ntawm "hmoov thiab ntaub thaiv npog", uas yog tua thiab tiv thaiv.Nrog kev nce qib ntawm kev ua tub rog thev naus laus zis, cov cuab yeej mos lub cev tau nyob deb ntawm qhov ua tau raws li qhov yuav tsum tau ua.Cov neeg pib siv cov ntaub ntawv nyuaj nrog cov mos mos lub cev armor, kom ua tiav qib siab ntawm kev tiv thaiv, cov khoom siv yog: steel phaj, titanium alloy, B4C, Si3N4, SiC, Al2O3 thiab lwm yam.
Hlau phaj yog thawj zaug siv rau hauv cov khoom siv lub cev tawv tawv, txawm hais tias nws zoo heev txhim kho qib kev tiv thaiv ntawm lub cev mos, tab sis kev tiv thaiv muaj peev xwm tsuas yog tiv thaiv kev tawm tsam ntawm cov mos txwv hlau lead thiab cov mos txwv zoo tib yam steel tub ntxhais, thiab muaj hnyav hnyav heev yooj yim mus dhia mos txwv thiab lwm yam shortcomings.
Ceramic cov ntaub ntawv txheeb ze rau steel phaj yog ntxiv txhim kho, lub teeb yuag ceev yog tsawg tshaj li ib nrab ntawm steel phaj, thiab tsis muaj ricochet phenomenon.
Tam sim no feem ntaubulletproof ceramic phajSpecifications: 250 * 300mm cambered los ua ke phaj.
Common specifications ntawm mos mos ceramic ntawv:
50 * 50 arc nto (370 ~ 400)
Hexagonal dav hlau (sab ntev 21mm)
Ib nrab daim, bevel lub kaum sab xis (25 * 50)
Kev ua tau zoo ntawm cov mos txwv ceramics:
Lub hauv paus ntsiab lus ntawm cov mos txwv ntawm ceramic thiab hlau yog txawv heev, hlau bulletproof phaj yog los ntawm yas deformation los nqus lub kinetic zog ntawm cov mos txwv, thaum ceramic mos txwv phaj yog los ntawm nws rupture los nqus lub kinetic zog ntawm cov mos txwv.
Bulletproof ceramics xav tau kev ua haujlwm ntau dua, xws li: ntom, porosity, hardness, tawg toughness, elastic modulus, ceev ntawm lub suab, txhua yam muaj zog, ib qho kev ua tau zoo tsis tuaj yeem muaj kev sib raug zoo thiab kev sib raug zoo nrog rau tag nrho cov mos txwv kev ua tau zoo, yog li lub tshuab tawg yog nyuaj heev, tawg tsim yog tshwm sim los ntawm ntau yam, thiab lub sij hawm luv heev.
①Porosity yuav tsum tsawg li tsawg tau los txhim kho hardness thiab elastic modulus, ceramic hardness yuav tsum siab tshaj cov mos txwv ya davhlau hardness.
② Hardness ncaj qha txiav txim siab cov mos txwv-resistant kev ua tau zoo ntawm mos txwv phaj.
③ Qhov ceev ncaj qha txiav txim siab qhov hnyav ntawm cov phom phom phom, vim tias qhov hnyav ntawm cov tub rog muaj peev xwm tsawg, yog li lub cev tawv tawv yuav tsum muaj qhov sib zog dua qhov zoo dua.
④ Kev faib tawm ntawm cov mos txwv ceramic: 95 alumina ceramic, 97 alumina ceramic, 99 alumina ceramic, thiab lwm yam.
Ntawm cov khoom siv ceramic feem ntau, B4C, Si3N4, SiC cov mos txwv-pov thawj kev ua tau zoo yog qhov zoo, tab sis tus nqi siab, Al2O3 muaj tus nqi qis, kev paub tab, yooj yim los tswj qhov loj me, qis sintering kub, yooj yim rau huab hwm coj ntau lawm thiab lwm yam zoo, tau dhau los ua cov khoom siv hauv cov mos txwv tsis zoo ceramics.
