Ukuba ukhangele “uphononongo lwesikrweqe esilula se-ballistic 2025″ okanye ulinganise iipros ze “UHMWPE bulletproof vest vs Kevlar”, usenokuba uqaphele intsingiselo ecacileyo: i-polyethylene yobunzima obuphezulu bemolekyuli (UHMWPE) igxotha ngokukhawuleza iKevlar yaseYurophu naseMelika.Imarike yezixhobo ezikhuselayo. Makhe sichaze ukuba kutheni le nto iphumeleleyo, kwaye yintoni i-China ehamba phambili yokuthumela ngaphandle isixelela ntoni malunga nemfuno yehlabathi.
I-Kevlar vs. UHMWPE Showdown: Kutheni i-Lightweight iphumelela
Kangangamashumi eminyaka, iKevlar ibilawula imveliso ngenxa yokomelela kwayo okuchukumisayo kunye nokufunxa amandla. Kodwa abasebenzisi banamhlanje—ukususela kumagosa ogcino-mthetho ukuya kwabo bathanda ukhuseleko lwabemi—banqwenela okungakumbi kunokhuseleko nje; bafuna izixhobo ezingayi kubanzima ngexesha leeshifti ezinde okanye kwiimeko zikaxakeka. Kulapho i-UHMWPE ikhanya khona
Ubunzima obuluncedo:I-UHMWPE ifikelela kwi-30% ikhaphukhaphu kuneKevlar kwinqanaba lokhuseleko elifanayo. Ivest eqhelekileyo ye-NIJ IIIA UHMWPE inobunzima obuncinci njenge-1.5kg, xa kuthelekiswa ne-2kg + ye-Kevlar elinganayo. Kwipolisa elijikelezayo kwi-8-hour shift shifts, loo mahluko ususa ukukhathala kwaye uphucula ukuhamba-okubalulekileyo ukuphendula ngokukhawuleza ngokukhawuleza.
Ukomelezwa koKuhlala:I-UHMWPE ixhathisa imitha ye-UV, iikhemikhali, kunye ne-abrasion ngokuphindwe kahlanu ngcono kune-Kevlar. Ayizukwehliswa emva kokuvezwa ngokuphindaphindiweyo kukukhanya kwelanga (umcimbi oqhelekileyo wokujikeleza kwangaphandle kwi-American Southwest) okanye ukufuma okungaselunxwemeni (umngeni kwimimandla yaseYurophu njenge-UK neFransi), ukwandisa ubomi begiya ngeminyaka emi-2-3 ngokomndilili.
Ukulingana kokuSebenza:Musa ukuphosakela ukukhanya njengobuthathaka. I-UHMWPE inamandla okweqile amaxesha angama-15 entsimbi, ehambelanayo okanye edlula amandla kaKevlar okumisa i-9mm kunye ne-.44 Magnum rounds-edibana neyona nto ingqongqo ye-NIJ (US) kunye ne-EN 1063 (iYurophu) imigangatho yokukhusela.
