Dab tsi yog meta-aramid, para-aramid yog dab tsi, thiab dab tsi yog qhov txawv ntawm lawv?
Poly-m-phenylene isophthalamide fiber yog hu ua meta-aramid luv luv; poly-para-phenylene terephthalamide fiber yog hu ua para-aramid luv luv.
Qhov txawv yog raws li nram no:
1. Cov txheej txheem molecular txawv. Cov meta-aramid fiber ntau muaj zigzag molecular saw saw; Para-aramid fiber ntau muaj cov kab sib txuas molecular.
2. Cov txheej txheem ntau lawm yog txawv. Vim tias cov txheej txheem nyuaj ntawm para-aramid ob-kauj ruam imitation txheej txheem, cov kev xav tau ntawm cov cuab yeej siv siab heev thiab cov txheej txheem nyuaj, thaum meta-aramid tsuas yog xav tau ib kauj ruam xwb.
3. Kev siv sib txawv. Meta-aramid yog dav siv los ua cov fiber ntau hauv kev tsim cov ntaub ntawv tshwj xeeb. Para-aramid fibrid fiber yog cov khoom sib txawv tshiab ntawm meta-aramid fibrid fiber. Nws lub luag haujlwm hauv kev ua haujlwm ntawm cov ntaub ntawv ua haujlwm siab
Cov ntaub ntawv txuas ntxiv
Lub ntsiab zoo ntawm kev siv para-aramid fiber ntau cov khoom:
Txo cov suab nrov, tsis ruaj khov thiab vibrating hnov; txo tus nqi hnav; smooths thiab polishes tshwm sim; txo corrosion; nce lub zog; txhim kho ntug stability; tiv thaiv cov ntaub thaiv kom tsis txhob tawg.
Aramid fiber ntau nta:
Aramid fiber ntau muaj zog heev, modulus, toughness, thiab muaj zoo rwb thaiv tsev kev ua tau zoo thiab kub kub kuj. Qhov ntev ntawm aramid fiber ntau yog txiav txim siab los ntawm kev ua haujlwm ntawm cov khoom, thiab cov lus qhia yog 2 ~ 80mm, lossis ntev dua.
aramid ntawv-raws li cov ntaub ntawv npaj los ntawm nws muaj cov yam ntxwv ntawm lub zog siab thiab siab modulus, lub teeb nplaim retardant, kub tsis kam, corrosion kuj, thiab zoo rwb thaiv tsev kev ua tau zoo. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob kub tiv thaiv hluav taws xob rau hluav taws xob, transformers, reactors, thiab lwm yam. Cov khoom siv yog ib qho tseem ceeb ntawm cov khoom siv los txhawb txoj kev loj hlob ntawm kev lag luam niaj hnub fais fab.
