Uma uke wacinga “izibuyekezo ze-ballistic lightweight armor 2025″ noma ukale ubuhle be-“UHMWPE bulletproof vest vs Kevlar”, kungenzeka ukuthi uqaphele ukuthambekela okucacile: i-ultra-high molecular weight polyethylene (UHMWPE) isusa ngokushesha i-Kevlar yendabuko eYurophu naseMelika.Imakethe yegiya lokuvikela. Ake sihlukanise ukuthi kungani lokhu kuphumelela kunqoba, nokuthi ukuthunyelwa kwe-China kwamanye amazwe kusitshelani mayelana nesidingo somhlaba wonke.
I-Kevlar vs. UHMWPE Showdown: Kungani I-Lightweight Iwina
Amashumi eminyaka, i-Kevlar ibibusa ukukhiqiza ngenxa yamandla ayo ahlaba umxhwele nokumunca amandla. Kodwa abasebenzisi banamuhla—kusukela kwabezomthetho kuye kwabathanda ukuphepha kwezakhamuzi—bafisa okungaphezu nje kokuvikelwa; bafuna igiya elingeke libasinde phakathi namashifu amade noma izimo eziphuthumayo. Kulapho kukhanya khona i-UHMWPE...
Inzuzo Yesisindo:I-UHMWPE ilula kufika ku-30% kune-Kevlar ngezinga elifanayo lokuvikela. Ivesti elijwayelekile le-NIJ IIIA UHMWPE lingaba nesisindo esincane njengo-1.5kg, uma kuqhathaniswa no-2kg+ kokulingana kwe-Kevlar. Ephoyisa eligada amashifu amahora angu-8, lowo mehluko uqeda ukukhathala futhi uthuthukisa ukuhamba—okubalulekile ekuphenduleni izimo eziphuthumayo ngokushesha.
I-Durability Boost:I-UHMWPE imelana nemisebe ye-UV, amakhemikhali, nokuhuzuka ngokuphindwe kahlanu kune-Kevlar. Ngeke kwehliswe isithunzi ngemva kokuchayeka kaningi ekukhanyeni kwelanga (inkinga evamile yamapatrola angaphandle eNingizimu-ntshonalanga yaseMelika) noma umswakamo wasogwini (inselele ezindaweni zase-Europe njenge-UK ne-France), okwelula ukuphila kwegiya ngeminyaka engu-2–3 ngokwesilinganiso.
Ukulingana kokusebenza:Ungaphazamisi ukukhanya njengobuthakathaka. I-UHMWPE inamandla aqinile aphindwe izikhathi ezingu-15 kunawensimbi, afanayo noma adlula ikhono lika-Kevlar lokumisa imizuliswano engu-9mm kanye ne-.44 Magnum—ehlangabezana nezindinganiso zokuvikela eziqinile ze-NIJ (US) kanye ne-EN 1063 (Europe).
