Niba warashatse "isuzuma ry'intwaro zoroheje za 2025″ cyangwa wapimye ibyiza bya "UHMWPE irinda amasasu vs Kevlar", ushobora kuba warabonye icyerekezo gisobanutse: polyethylene ifite uburemere bwa molekile nyinshi (UHMWPE) iri kwimura vuba Kevlar isanzwe mu Burayi no muri Amerika.isoko ry’ibikoresho byo kurinda. Reka turebe impamvu ibi bikoresho bitsinda, n’icyo kwiyongera kw’ibicuruzwa byoherezwa mu mahanga mu Bushinwa bitubwira ku bijyanye n’ibikenewe ku isi.
Irushanwa rya Kevlar na UHMWPE: Impamvu Lightweight Itsinda
Mu myaka ibarirwa muri za mirongo, Kevlar yiganje mu musaruro wayo bitewe n’imbaraga zayo zikomeye zo gukurura no gukoresha ingufu. Ariko abakoresha bo muri iki gihe—kuva ku bashinzwe iyubahirizwa ry’amategeko kugeza ku bakunda umutekano w’abasivili—ntibifuza gusa uburinzi; bashaka ibikoresho bitazabaremerera mu gihe cy’akazi kabaremereye cyangwa mu bihe byihutirwa. Aho niho UHMWPE igaragara cyane.
Akamaro k'uburemere:UHMWPE yoroheje kugeza kuri 30% kurusha Kevlar ku rwego rumwe rwo kurinda. Ikoti risanzwe rya NIJ IIIA UHMWPE rishobora gupima ibiro 1.5 gusa, ugereranije na 2kg+ ku bikoresho bingana na Kevlar. Ku mupolisi ukora akazi k'amasaha 8, iryo tandukaniro rikuraho umunaniro kandi rikongera ubushobozi bwo kugenda—ni ingenzi cyane mu guhangana n'ibibazo byihutirwa.
Kongera ubushobozi bwo kuramba:UHMWPE irwanya imirasire ya UV, imiti, no kwangirika inshuro eshanu kurusha Kevlar. Ntabwo izangirika nyuma yo kwibasirwa n'izuba kenshi (ikibazo gikunze kugaragara ku bashinzwe irondo bo hanze mu majyepfo y'uburengerazuba bwa Amerika) cyangwa ubushuhe bwo ku nkombe z'inyanja (ikibazo mu turere tw'i Burayi nk'Ubwongereza n'Ubufaransa), bikongera igihe cyo kubaho cy'ibikoresho ku myaka 2-3 ugereranije.
Uburinganire bw'Imikorere:Ntukibeshye ko ubworoshye ari intege nke. UHMWPE ifite imbaraga zo gukurura inshuro 15 z'icyuma, ihuye cyangwa irenga ubushobozi bwa Kevlar bwo guhagarika 9mm na .44 Magnum rounds—yujuje amahame akomeye yo kurinda NIJ (US) na EN 1063 (Uburayi).
