Kevlar vs. UHMWPE Showdown: Vim Li Cas Lightweight Yeej
Tau ntau xyoo lawm, Kevlar tau tswj hwm kev tsim khoom vim nws lub zog tensile zoo kawg thiab kev nqus hluav taws xob. Tab sis cov neeg siv niaj hnub no - txij li cov tub ceev xwm mus rau cov neeg nyiam kev nyab xeeb pej xeem - xav tau ntau dua li kev tiv thaiv; lawv xav tau cov khoom siv uas yuav tsis ua rau lawv hnyav thaum lub sijhawm ua haujlwm ntev lossis xwm txheej ceev. Qhov ntawd yog qhov uas UHMWPE ci ntsa iab.
Qhov hnyav zoo dua:UHMWPE sib dua li Kevlar txog li 30% rau tib theem kev tiv thaiv. Lub tsho tiv no NIJ IIIA UHMWPE tus qauv tuaj yeem hnyav tsawg li 1.5kg, piv rau 2kg+ rau Kevlar sib npaug. Rau tus tub ceev xwm uas saib xyuas 8-teev ua haujlwm, qhov sib txawv ntawd tshem tawm qhov qaug zog thiab txhim kho kev txav mus los - tseem ceeb rau kev teb rau xwm txheej ceev ceev.
Kev Txhim Kho Kev Ruaj Ntseg:UHMWPE tiv taus cov teeb UV, cov tshuaj lom neeg, thiab kev puas tsuaj tsib zaug zoo dua Kevlar. Nws yuav tsis lwj tom qab raug tshav ntuj ntau zaus (qhov teeb meem feem ntau rau cov tub rog sab nraum zoov hauv Asmeskas Sab Qab Teb) lossis cov av noo ntawm ntug dej hiav txwv (qhov teeb meem hauv cov cheeb tsam European xws li UK thiab Fabkis), ua rau lub iav siv tau ntev li 2-3 xyoos.
Kev Ua Tau Zoo Sib Npaug:Tsis txhob xav tias qhov sib dua yog qhov tsis muaj zog. UHMWPE muaj lub zog tensile 15 npaug ntawm cov hlau, sib phim lossis tshaj Kevlar lub peev xwm los nres 9mm thiab .44 Magnum mos txwv - ua tau raws li NIJ (Tebchaws Meskas) thiab EN 1063 (Tebchaws Europe) cov qauv kev tiv thaiv nruj tshaj plaws.
