Yog tias koj tau tshawb nrhiav "lub teeb hnyav ballistic armor tshuaj xyuas 2025" lossis ntsuas qhov zoo ntawm "UHMWPE mos txwv tsho tiv thaiv kev sib tw", koj yuav pom qhov txawv txav: ultra-siab molecular hnyav polyethylene (UHMWPE) yog sai hloov cov tsoos Kevlar hauv Tebchaws Europe thiab Amelikas.kev lag luam tiv thaiv iav. Cia peb rhuav tshem vim li cas cov khoom siv no yeej, thiab qhov uas Tuam Tshoj tus xa tawm tau nce siab qhia peb txog kev thov thoob ntiaj teb.
Kevlar vs UHMWPE Showdown: Vim Li Cas Lub Teeb Yeej
Tau ntau xyoo lawm, Kevlar dominated ntau lawm ua tsaug rau nws impressive tensile zog thiab lub zog nqus. Tab sis cov neeg siv niaj hnub no - los ntawm cov tub ceev xwm mus rau cov neeg nyiam kev nyab xeeb - xav ntau tshaj li kev tiv thaiv xwb; lawv xav tau cov iav uas yuav tsis hnyav rau lawv thaum lub sijhawm ua haujlwm ntev lossis muaj xwm txheej ceev. Qhov ntawd yog qhov UHMWPE ci.
Qhov hnyav Advantage:UHMWPE muaj txog li 30% sib zog dua Kevlar rau tib qib kev tiv thaiv. Tus qauv NIJ IIIA UHMWPE tsho khuam tuaj yeem hnyav li 1.5kg, piv rau 2kg + rau Kevlar sib npaug. Rau cov tub ceev xwm saib xyuas kev hloov pauv 8-teev, qhov sib txawv ntawd tshem tawm kev qaug zog thiab txhim kho kev txav mus los - tseem ceeb rau kev teb rau cov xwm txheej ceev ceev.
Durability Boost:UHMWPE tiv thaiv UV rays, tshuaj lom neeg, thiab abrasion tsib zaug zoo dua Kevlar. Nws yuav tsis degrade tom qab rov raug tshav ntuj (ib qho teeb meem tshwm sim rau kev saib xyuas sab nraum zoov hauv Asmeskas Sab Qab Teb Sab Hnub Tuaj) lossis ntug hiav txwv av (ib qho kev sib tw hauv cov cheeb tsam nyob sab Europe xws li UK thiab Fabkis), txuas ntxiv lub iav lub neej los ntawm 2-3 xyoos nyob rau nruab nrab.
Performance Parity:Tsis txhob yuam kev lightness rau qaug zog. UHMWPE muaj lub zog tensile 15 npaug ntawm cov hlau, sib piv lossis tshaj Kevlar lub peev xwm nres 9mm thiab .44 Magnum rounds-ua tau raws li cov qauv kev tiv thaiv nruj tshaj NIJ (US) thiab EN 1063 (Tebchaws Europe).
