Aramid fiber ntauyog cov khoom siv hluav taws xob ua haujlwm siab, nrog lub zog ultra-siab, siab modulus, siab kub tsis kam, acid thiab alkali tsis kam, hnav, thiab lwm yam zoo heev. Nws lub zog tuaj yeem ncav cuag 5-6 npaug ntawm cov hlau hlau, cov qauv yog 2-3 npaug ntawm cov hlau hlau lossis iav fiber ntau, qhov hnyav yog 2 npaug ntawm cov hlau hlau, thiab qhov hnyav tsuas yog 1/5 ntawm cov hlau hlau. Ntawm qhov kub ntawm 560 ℃, aramid fibers tuaj yeem nyob ruaj khov, tsis txhob decompose, thiab tsis yaj. Tsis tas li ntawd, nws muaj cov rwb thaiv tsev zoo thiab tiv thaiv kev laus, thiab lub neej ua haujlwm ntev. Tam sim no, cov khoom siv tiv thaiv cov mos txwv tseem ceeb (xws li cov tsho tiv thaiv mos txwv, thiab cov kaus mom tiv thaiv mos txwv) feem ntau siv.aramid fiber ntau. Ntawm lawv, lub ntiajteb txawj nqus aramid fiber ntau daim ntaub yog ib qho ntawm cov ntaub ntawv tseem ceeb nyob rau hauv lub tshav pob ntawm bulletproofing. Piv nrog cov nylon undershirts thiab cov kaus mom hlau, cov mos txwv undershirts thiab kaus mom hlau nrog ntxiv aramid fibers tsis tsuas yog me me thiab sib dua tab sis kuj 40% zoo dua tiv thaiv cov mos txwv.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tsho tiv thaiv cov mos txwv tuaj yeem nkag siab zoo li no: thaum lub mos txwv tsoo cov ntaub txheej ntawm lub tsho khuam, kev poob siab thiab cov strain nthwv dej yog tsim nyob ib ncig ntawm qhov cuam tshuam. Cov nthwv dej no los ntawm kev nthuav tawm sai thiab nthuav dav ntawm cov fiber ntau, tuaj yeem txav mus rau hauv ntau cov fibers, thiab tom qab ntawd hauv thaj chaw loj heev kom nqus tau lub zog ntawm kev poob siab. Nws yog qhov kev nqus hluav taws xob ntau uas ua rau txo qis qhov cuam tshuam ntawm cov mos txwv ntawm tib neeg lub cev, yog li paub txog kev tiv thaiv cov tsho tiv thaiv cov mos txwv.
Bulletproof khoom thiab nws cov kev ua tau zoo heev
Cov tub ntxhais ntawm cov tsho tiv thaiv mos txwv yog nyob rau hauv cov ntaub ntawv muaj zog fiber ntau uas lawv siv, uas yog cov para-aramid fibers, tseem hu ua para-aromatic polyamide fibers, yog cov khoom siv phom sij heev. Nws cov qauv tshuaj symmetrical heev muab cov saw hlau molecular zoo rigidity, ua rau nws txawv ntawm cov qauv hloov pauv tau yooj yim polymers nyob rau hauv cov nqe lus ntawm solubility, rheological zog, thiab ua.
Para-aramid fibers paub txog lawv lub cev zoo heev thiab cov khoom siv kho tshuab, suav nrog lub zog ultra-siab, siab modulus, thiab lub teeb yuag. Lawv lub zog tshwj xeeb yog tsib mus rau rau lub sijhawm siab dua li cov pa hlau hlau, thiab lawv cov qauv tshwj xeeb tshaj li ntawm cov hlau hlau los ntawm ib qho ntawm ob mus rau peb. Tsis tas li ntawd, cov fibers muaj cov khoom siv thermal zoo, nrog rau qhov kub thiab txias, tsis tshua muaj kev nthuav dav, thiab thermal conductivity tsawg, thiab tsis hlawv lossis yaj. Para-aramid fibers tseem hu ua "bulletproof fibers" vim tias lawv cov rwb thaiv tsev zoo, kev tiv thaiv corrosion, thiab kev laus ua haujlwm.
Daim ntawv thov thiab kev cia siab ntawm Para-Aramid Fiber ntau
Para-aramid fiber ntau, cov khoom siv tseem ceeb hauv kev tiv thaiv thiab kev ua tub rog kev lag luam, tau siv dav thoob ntiaj teb. Raws li kev txheeb cais, qhov kev faib ua feem ntawm aramid hauv kev tiv thaiv fibers hauv Asmeskas yog ntau dua 50% thiab 10% hauv Nyiv. Nws cov yam ntxwv sib sib zog nqus ua rau aramid cov tsho tiv thaiv mos txwv thiab kaus mom hlau, uas tuaj yeem txhim kho cov tub rog txoj kev muaj peev xwm teb sai sai. Tsis tas li ntawd, para-aramid yog dav siv hauv tsheb, kev sib txuas lus, aerospace, thiab kev ua si sab nraum zoov vim nws ua tau zoo heev.
