Ukuba ukhe wakhangela "uphononongo lwezixhobo ze-ballistic armor ezikhaphukhaphu ezingama-2025″ okanye walinganisa iingenelo ze-"UHMWPE bulletproof vest vs Kevlar", kusenokwenzeka ukuba uqaphele umkhwa ocacileyo: i-polyethylene enobunzima be-molecular ephezulu kakhulu (UHMWPE) ikhawuleza ithathe indawo yeKevlar yendabuko eYurophu naseMelika.imakethi yezixhobo zokuzikhusela. Masichaze isizathu sokuba ezi zinto ziphumelele, kunye noko kuthethwa kukwanda kokuthunyelwa kwamanye amazwe yiTshayina malunga nemfuno yehlabathi.
Umboniso weKevlar vs. UHMWPE: Kutheni iLightweight iphumelela
Kangangamashumi eminyaka, iKevlar ibilawula imveliso ngenxa yamandla ayo amangalisayo okutsalwa kunye nokufunxwa kwamandla. Kodwa abasebenzisi banamhlanje—ukususela kumagosa omthetho ukuya kubathandi bokhuseleko lwabantu—banqwenela okungaphezulu nje kokhuseleko; bafuna izixhobo ezingazukubasinda ngexesha leeshifti ezinde okanye iimeko ezingxamisekileyo. Kulapho i-UHMWPE ikhanya khona.
Inzuzo yoBunzima:I-UHMWPE ikhaphukhaphu ukuya kuthi ga kwi-30% kuneKevlar kwinqanaba elifanayo lokhuseleko. Ivesti eqhelekileyo ye-NIJ IIIA UHMWPE inobunzima obuyi-1.5kg, xa ithelekiswa ne-2kg+ kwiimpahla ezilingana neKevlar. Kwipolisa elihambahamba iiyure ezisi-8, loo mahluko uyayisusa idinwe kwaye uphucule ukuhambahamba—kubalulekile ekuphenduleni kwiimeko ezingxamisekileyo ngokukhawuleza.
Ukuphucula Ukuqina:I-UHMWPE imelana nemisebe ye-UV, iikhemikhali, kunye nokurhawuzelelwa ngokuphindwe kahlanu kuneKevlar. Ayizukubola emva kokuvezwa elangeni ngokuphindaphindiweyo (ingxaki eqhelekileyo kumapolisa angaphandle eMzantsi-ntshona waseMelika) okanye ukufuma konxweme (umngeni kwimimandla yaseYurophu efana ne-UK neFransi), yandisa ubomi bezixhobo ngeminyaka emi-2-3 ngokomyinge.
Ukulingana koMsebenzi:Musa ukubhidanisa ubukhaphukhaphu nobuthathaka. I-UHMWPE inamandla okutsalwa ngokuphindwe kalishumi elinesihlanu kunentsimbi, ifanisa okanye idlula amandla eKevlar okumisa iirowu ze-9mm kunye ne-.44 Magnum—ihlangabezana nemigangatho yokhuseleko engqongqo ye-NIJ (US) kunye ne-EN 1063 (Europe).
