Ngatitsanangure kuti sei zvinhu izvi zviri kukunda, uye kuti kuwedzera kwekutengesa zvinhu kunze kwenyika kweChina kunotiudzei nezvekudiwa kwepasi rose.
Kurwisana kweKevlar vs. UHMWPE: Nei Lightweight Ichikunda
Kwemakumi emakore, Kevlar yainyanya kugadzira mota nekuda kwesimba rayo rinorema rekudhonza uye kunwa simba rayo. Asi vashandisi vemazuva ano—kubva kumapurisa kusvika kune vanoda kuchengetedzeka kwevanhuwo zvavo—vanoda zvinopfuura kungodzivirirwa chete; vanoda michina isingazovaremedzi panguva dzekushanda kwenguva refu kana dzenjodzi. Ndipo panonyanya kuoneka UHMWPE.
Kubatsira kweHuremu:UHMWPE yakareruka kusvika 30% kupfuura Kevlar nekuda kwekudzivirira kwakafanana. Vhesi reNIJ IIIA UHMWPE rinogona kurema zvishoma se1.5kg, zvichienzaniswa ne2kg+ yeKevlar yakaenzana nayo. Kune mupurisa ari kufamba-famba kwemaawa masere, mutsauko iwoyo unobvisa kuneta uye unovandudza kufamba-famba—zvakakosha pakuita zvinhu zvinokurumidza kuitika.
Kusimudzira Kugara Kwenguva Refu:UHMWPE inodzivirira mwaranzi yeUV, makemikari, uye kukwesha zviri nani kupfuura Kevlar kashanu. Haizomboori mushure mekuratidzwa nezuva kakawanda (dambudziko rinowanzoitika kune vanoongorora vari kunze kuAmerican Southwest) kana hunyoro hwegungwa (dambudziko munzvimbo dzeEurope dzakadai seUK neFrance), zvichiita kuti hupenyu hwegiya huwedzere nemakore 2-3 paavhareji.
Kuenzana Kwekushanda:Musati kureruka ndiko kusasimba. UHMWPE ine simba rekudhonza rakapetwa kagumi neshanu pane resimbi, richienzanisa kana kupfuura kugona kwaKevlar kumisa mabhora e9mm ne .44 Magnum—ichisangana nezvinodiwa zvakanyanya zveNIJ (US) neEN 1063 (Europe).
