Alumina ceramic yog ib hom khoom siv uas muaj zog thiab hnav tsis kam, raws li cov ntsiab lus Al2O3 sib txawv, nws muaj peev xwm muab faib ua 99% alumina ceramic, 95% alumina ceramic, 96% alumina ceramic, 92% alumina ceramic thiab lwm yam. Cov yam ntxwv tseem ceeb yog kev tiv taus kub, kev tiv taus corrosion, kev hnav tsis kam thiab kev cuam tshuam, uas yog cov khoom siv ceramic tshwj xeeb hauv kev lag luam.
Cov qauv kev loj hlob ntawm cov ntaub ntawv ua rog yog ua kom tawv, sib dua, ua haujlwm tau ntau yam thiab ua haujlwm tau zoo. Cov khoom siv ceramic yog ib feem tseem ceeb ntawm cov ntaub ntawv tiv thaiv mos txwv, uas muaj qhov nyuaj thiab hnav tsis kam, muaj zog compressive thiab ua tau zoo heev hauv qab kev ntxhov siab siab.
99% alumina ceramics siv tau ua cov khoom siv ceramics uas tiv taus mos txwv. Vim nws qhov tawv thiab lub zog siab, thaum lub mos txwv ntaus rau saum npoo ntawm cov khoom siv ceramic, nws tsim lub zog loj heev, lub zog ntaus nthuav mus rau cov khoom siv ceramics thiab lub mos txwv, thiab nyob rau hauv lub zog ntaus, cov khoom siv ceramics tawg me ntsis, tiv taus lub zog nkag ntawm lub mos txwv. Alumina bulletproof ceramics nqus lub zog kinetic ntawm lub mos txwv los ntawm kev tawg me me, kom ua tiav lub luag haujlwm ntawm kev tiv taus mos txwv. Cov khoom siv ceramics uas tiv taus mos txwv muaj zog peb mus rau plaub npaug ntau dua li cov hlau hlau, muab kev tiv thaiv siab dua li cov hlau hlau.
Tau kawg, vim yog qhov brittleness ntawm ceramics, tsuas yog vam khom rau cov ceramics lawv tus kheej, tsis tuaj yeem ua "ruaj khov". Cov ceramics tiv thaiv mos txwv feem ntau yog muab tso rau ntawm qhov chaw ntawm lub foob pob, kom sib txuas ua ke nrog lwm cov ntaub ntawv thaub qab, cov cuab yeej sib xyaw ua ke siv feem ntau. Lub luag haujlwm tseem ceeb ntawm cov ntaub ntawv thaub qab yog nqus cov zog ballistic seem.
Yuav kom txhim kho qhov tsis kam ntawm cov khoom siv ceramic rau ntau qhov kev tawm tsam, cov vaj huam sib luag ceramic feem ntau yog coated nrog cov ntaub fiber muaj zog siab kom tiv thaiv kev tawg los ntawm kev tawm tsam mos txwv. Kev sib xyaw ua ke ntawm cov khoom siv ceramic tawv muaj zog thiab cov khoom siv rov qab ruaj khov yog cov qauv tseem ceeb ntawm cov cuab yeej ua los ntawm cov khoom siv ceramic niaj hnub.
Kev ua tsov rog niaj hnub no tseem yeej lossis poob los ntawm kev daws qhov teeb meem ntawm rab hmuv thiab daim hlau thaiv. Phom, phom loj thiab foob pob yog rab hmuv, thaum cov cuab yeej tiv thaiv mos txwv yog daim hlau thaiv. Hauv kev tawm tsam kev ua phem thiab kev ua phem thiab hauv kev ua tsov rog loj niaj hnub no, cov cuab yeej tiv thaiv mos txwv tuaj yeem txo cov neeg raug mob, txhim kho kev ua tau zoo ntawm kev sib ntaus sib tua thiab ua rau muaj kev yeej ntau ntxiv.
