Ngati mudasaka "ndemanga zopepuka za zida zankhondo 2025" kapena kuyeza zabwino za "UHMWPE bulletproof vest vs Kevlar", mwina mwazindikira zomwe zimachitika: ultra-high molecular weight polyethylene (UHMWPE) ikusintha mwachangu Kevlar ku Europe ndi America.Msika wa zida zoteteza. Tiyeni tifotokoze chifukwa chake zinthuzi zikupambana, komanso zomwe ku China kutulutsa kunja kumatiuza za kufunikira kwapadziko lonse lapansi.
The Kevlar vs. UHMWPE Showdown: Chifukwa Chake Opepuka Amapambana
Kwa zaka zambiri, Kevlar ankakonda kupanga chifukwa cha mphamvu zake zolimba komanso kuyamwa kwake. Koma ogwiritsa ntchito masiku ano—kuyambira apolisi mpaka okonda zachitetezo cha anthu wamba—amalakalaka zambiri osati kungotetezedwa; amafuna zida zomwe sizidzawalemetsa panthawi yayitali kapena pakagwa mwadzidzidzi. Ndipamene UHMWPE imawalira
Ubwino Wonenepa:UHMWPE ndi yopepuka mpaka 30% kuposa Kevlar pamlingo wotetezedwa womwewo. Chovala chodziwika bwino cha NIJ IIIA UHMWPE chimatha kulemera pang'ono ngati 1.5kg, poyerekeza ndi 2kg+ pazofanana ndi Kevlar. Kwa wapolisi yemwe amalondera mashifiti a maola 8, kusiyana kumeneko kumachepetsa kutopa komanso kumapangitsa kuyenda bwino - kofunikira kwambiri poyankha mwadzidzidzi.
Durability Boost:UHMWPE imalimbana ndi kuwala kwa UV, mankhwala, ndi abrasion kuposa Kevlar. Sizidzanyozeka pambuyo poyang'ana dzuŵa mobwerezabwereza (nkhani yofala kwa oyendayenda ku America Kumwera chakumadzulo) kapena chinyezi cha m'mphepete mwa nyanja (zovuta m'madera a ku Ulaya monga UK ndi France), kukulitsa moyo wa gear ndi zaka 2-3 pafupifupi.
Performance Parity:Musaganize kupepuka ngati kufooka. UHMWPE ili ndi mphamvu zolimba kuwirikiza ka 15 kuposa chitsulo, chofananira kapena choposa mphamvu ya Kevlar kuyimitsa 9mm ndi .44 Magnum kuzungulira-kukwaniritsa miyezo yolimba kwambiri ya NIJ (US) ndi EN 1063 (Europe).
