Kevlar (Kevlar) yog lub npe ntawm cov khoom lag luam ntawm DuPont, uas yog ib hom khoom siv polymer.Nws lub npe tshuaj yog "poly (terephthalamide)", feem ntau hu ua "aramid fiber".
Aramid yog lub npe dav dav ntawm aromatic polyamide.Piv nrog rau cov khoom siv polyamide xws li nylon 6 thiab nylon 66, aramid muaj cov khoom zoo heev xws li ultra-siab zog, siab modulus thiab kub tsis kam vim hais tias cov roj carbon fiber ntau nyob rau hauv cov saw molecular yog hloov los ntawm nruj benzene nplhaib qauv.Muaj ntau ntau hom aramid fibers, thiab aramid fiber ntau 1313 thiab aramid fiber 1414 yog dav siv.Kevlar sib raug rau aramid fiber ntau 1414. Cov tshuaj npe ntawm aramid fiber 1313 yog polyphthalamide, uas yog cov khoom siv hluav taws xob zoo heev.
Tam sim no, qhov kev thov txhua xyoo ntawm para-aramid fiber ntau (aramid fiber ntau 1414) hauv Suav teb yog ntau tshaj 5,000 tons, feem ntau vam khom rau kev xa khoom, thiab cov nqi lag luam kuj tseem siab, txog 200,000 yuan / tuj.Cov neeg tsim khoom tseem ceeb yog DuPont hauv Tebchaws Meskas thiab Teijin hauv Nyij Pooj.
Raws li m-aramid fiber ntau (aramid fiber ntau 1313), "Taimeida" tsim los ntawm Yantai Taihe New Materials Co., Ltd.Cov neeg muab khoom thoob ntiaj teb ntawm m-aramid fiber ntau yog DuPont hauv Tebchaws Meskas thiab Teijin hauv Nyij Pooj.Dupont muaj kev lag luam siab tshaj plaws thiab cov khoom lag luam nplua nuj, thiab tseem yog tus thawj coj hauv kev lag luam thoob ntiaj teb.
