Meta-aramids feem ntau yog tsim los ntawm kev sib xyaw ntawm para- thiab meta-phenylenediamine thiab terephthalic acid. Cov ntaub ntawv no yog rhuab thiab spun rau hauv fibers, uas yog ces woven los yog knit rau hauv ntaub. Cov khoom uas tau tshwm sim yog tsis-conductive, nplaim-retardant, thiab muaj zog heev, ua rau nws zoo tagnrho rau siv nyob rau hauv ib tug xov tooj ntawm kev lag luam thiab kev lag luam daim ntawv thov.
Ib qho ntawm cov kev siv tseem ceeb rau cov meta-aramids yog tsim cov khaub ncaws tiv thaiv rau cov neeg ua haujlwm hauv qhov chaw muaj kev phom sij. Cov fibers no feem ntau siv nrog rau lwm cov ntaub ntawv tiv thaiv, xws li Nomex lossis Kevlar, los tsim cov iav tiv thaiv zoo heev. Cov iav no feem ntau hnav los ntawm cov neeg ua haujlwm hauv kev lag luam xws li roj thiab roj, kev tsim tshuaj lom neeg, thiab kev tua hluav taws, qhov chaw raug tshav kub, nplaim taws, thiab lwm yam khoom siv phom sij yog qhov pheej hmoo.
Ntxiv nrog rau cov khaub ncaws tiv thaiv, meta-aramids kuj tseem siv rau ntau yam kev siv. Piv txwv li, cov fibers no feem ntau siv rau hauv kev tsim cov lim dej rau huab cua thiab dej huv. Lawv kuj tseem siv rau hauv kev tsim cov ntaub ntawv rwb thaiv tsev rau kev xaim thiab cov kav dej, thiab txawm siv los ua cov kev ua tau zoo ntawm kev sib tw sails rau cov nkoj.
Txawm hais tias lawv lub zog thiab ua haujlwm ntev, cov meta-aramids kuj hnav thiab xis hnav. Qhov no ua rau lawv yog ib qho kev xaiv zoo tshaj plaws rau cov khaub ncaws tiv thaiv uas yuav tsum tau hnav rau lub sijhawm ntev, vim tias cov neeg ua haujlwm tsis tshua muaj kev qaug zog lossis tsis xis nyob thaum hnav cov iav ua los ntawm cov ntaub ntawv no.
Hauv kev xaus, meta-aramids yog cov khoom siv tseem ceeb siv hauv ntau hom kev lag luam thiab kev lag luam. Los ntawm kev tiv thaiv khaub ncaws rau cov neeg ua haujlwm nyob rau hauv qhov chaw muaj kev phom sij rau cov lim cua thiab dej huv, cov fibers no muaj ntau yam thiab siv tau zoo. Yog li ntawd, lawv zoo li yuav nyob twj ywm yog cov khoom tseem ceeb hauv kev tsim cov iav tiv thaiv rau xyoo tom ntej.
