Cov ceramic siv rau cov phaj tiv thaiv bulletproof dab tsi?
Cov khoom siv av nplaum hauv cov phaj tiv taus feem ntau siv peb yam khoom sib txawv hauv qab no:
1. Cov khoom siv alumina
Alumina ceramics muaj qhov ceev tshaj plaws ntawm peb cov ntaub ntawv. Hauv qab tib thaj chaw, cov phaj tiv thaiv mos txwv ua los ntawm alumina ceramics hnyav dua. Tab sis tus nqi ntawm alumina ceramics qis heev. Yog li ntawd, qee tus neeg siv khoom uas xav tau kev yuav khoom loj yuav xaiv cov phaj tiv thaiv mos txwv no.
2. Cov khoom siv silicon carbide ceramics
Nws tus nqi kim heev, 4 txog 5 npaug ntawm alumina ceramics, tab sis qhov hnyav dua tuaj yeem coj kev paub zoo dua thiab txo qhov kev siv zog ntawm lub cev. Yog tias nws yog tus neeg siv khoom uas muaj nyiaj txaus, nws raug pom zoo kom xaiv hom phaj tiv thaiv mos txwv no.
3. Boron carbide ceramics
Tus nqi ntawm boron carbide kim heev, uas tuaj yeem ncav cuag 8 txog 10 npaug ntawm silicon carbide. Vim nws muaj nqis siab, feem ntau peb tsuas yog siv cov khoom no hauv NIJ IV bulletproof phaj.
