Uma uke wafuna “ukubuyekezwa kwezikhali ze-ballistic armor ezilula ezingama-2025″ noma walinganisa izinzuzo ze-“UHMWPE bulletproof vest vs Kevlar”, kungenzeka ukuthi uqaphele ukuthambekela okucacile: i-polyethylene enesisindo sama-molecule esiphezulu kakhulu (UHMWPE) isusa ngokushesha i-Kevlar yendabuko eYurophu naseMelika.imakethe yezimpahla zokuzivikela. Ake sichaze ukuthi kungani lokhu kuphumelela, nokuthi ukwanda kokuthunyelwa kwamanye amazwe kwe-China kusitshelani ngesidingo somhlaba wonke.
Ukungqubuzana kweKevlar vs. UHMWPE: Kungani Ubunzima Buphumelela
Sekungamashumi eminyaka, iKevlar ibusa umkhiqizo ngenxa yamandla ayo anamandla okubamba kanye nokumunca amandla. Kodwa abasebenzisi banamuhla—kusukela ezikhulwini zomthetho kuya kubathandi bezokuphepha bezakhamuzi—bafisa okungaphezu nje kokuvikelwa; bafuna imishini engeke ibathwalise kanzima ngesikhathi sokusebenza isikhathi eside noma izimo eziphuthumayo. Yilapho i-UHMWPE ikhanya khona.
Inzuzo Yesisindo:I-UHMWPE ilula ngo-30% kune-Kevlar ngezinga elifanayo lokuvikela. Ivesti ejwayelekile ye-NIJ IIIA UHMWPE ingaba nesisindo esingama-1.5kg, uma kuqhathaniswa no-2kg+ wezinto ezilingana ne-Kevlar. Kumaphoyisa ahamba amahora angu-8, lowo mehluko uqeda ukukhathala futhi uthuthukise ukuhamba—okubalulekile ekuphenduleni ezimweni eziphuthumayo ngokushesha.
Ukuthuthukiswa Kokuqina:I-UHMWPE imelana nemisebe ye-UV, amakhemikhali, kanye nokuguguleka okungcono ngokuphindwe kahlanu kune-Kevlar. Ngeke yonakale ngemva kokuchayeka elangeni ngokuphindaphindiwe (inkinga evamile yokuqapha kwangaphandle eNingizimu-ntshonalanga yaseMelika) noma umswakama ogwini (inselele ezifundeni zaseYurophu njenge-UK neFrance), okwandisa isikhathi sokuphila kwegiya ngeminyaka engu-2-3 ngokwesilinganiso.
Ukulingana Kokusebenza:Ungaphambanisi ukukhanya nobuthakathaka. I-UHMWPE inamandla okudonseka aphindwe kayi-15 kunensimbi, ifanisa noma idlula ikhono likaKevlar lokumisa ama-9mm kanye nama-.44 Magnum rounds—ihlangabezana nezindinganiso zokuvikela ze-NIJ (US) kanye ne-EN 1063 (Europe).
