Niba warashakishije "ibirwanisho byoroheje byerekana imipira 2025 ″ cyangwa ugapima ibyiza bya" UHMWPE bulletproof vest vs Kevlar ", ushobora kuba wabonye icyerekezo kigaragara: uburemere bukabije bwa molekile polyethylene (UHMWPE) burimura vuba Kevlar gakondo muburayi no muri Amerika'Kurinda ibikoresho. Reka dusenye impamvu ibi bikoresho bigenda neza, hamwe nibyo ibicuruzwa byoherezwa mu mahanga mubushinwa bitubwira kubyerekeye isi ikenewe.
Kevlar na UHMWPE Kwerekana: Impamvu Umucyo Watsinze
Mu myaka ibarirwa muri za mirongo, Kevlar yiganjemo umusaruro bitewe n'imbaraga zayo zitangaje no kwinjiza ingufu. Ariko abakoresha uyumunsi - uhereye kubashinzwe kubahiriza amategeko kugeza kubakunda umutekano wabasivili - bifuza kurengera gusa; bashaka ibikoresho bitazabapima mugihe kirekire cyangwa ibintu byihutirwa. Aho niho UHMWPE imurikira.
Ibyiza by'ibiro:UHMWPE iroroshye kugera kuri 30% kurusha Kevlar kurwego rumwe rwo kurinda. Ikoti risanzwe rya NIJ IIIA UHMWPE rishobora gupima nkibiro 1.5 kg, ugereranije na 2kg + kubingana na Kevlar. Ku mupolisi ukora irondo amasaha 8, iryo tandukaniro rikuraho umunaniro kandi riteza imbere kugenda - ni ngombwa mu gutabara vuba.
Kuramba:UHMWPE irwanya imirasire ya UV, imiti, hamwe no gukuramo inshuro eshanu kurenza Kevlar. Ntabwo izangirika nyuma yo guhura nizuba ryinshi (ikibazo gikunze kugaragara kumarondo yo hanze muri Amerika yepfo yepfo yuburengerazuba) cyangwa ubuhehere bwinyanja (ikibazo mukarere k’uburayi nku Bwongereza n’Ubufaransa), kongerera igihe cyo gukoresha ibikoresho imyaka 2-33 ugereranije.
Uburinganire bw'imikorere:Ntukibeshye umucyo kubera intege nke. UHMWPE ifite imbaraga zingana inshuro 15 z'ibyuma, bihuye cyangwa birenze ubushobozi bwa Kevlar bwo guhagarika 9mm na .44 Magnum-byujuje ubuziranenge bwa NIJ (US) na EN 1063 (Uburayi).
