Aramid Fiber hauv Nplaim Retardant Fabrics

Aramid fibers, tshwj xeeb tshaj yog meta-aramid thiab para-aramid, ua lub luag haujlwm tseem ceeb hauv kev tsim cov nplaim hluav taws kub. Cov hluavtaws fibers no paub txog lawv lub zog, tiv thaiv tshav kub, thiab kav ntev, ua rau lawv zoo tagnrho rau kev tiv thaiv khaub ncaws hauv ntau qhov chaw muaj kev pheej hmoo siab.

 

Meta-aramid: Qhov Muag, Kev Xaiv Ua Si
Meta-aramids yog tsim los ntawm ntub spinning, uas ua rau semi-crystalline fibers nrog molecular chains ib nrab oriented raws lub fiber axis. Cov fibers no muaj peev xwm tiv taus cua sov, tshuaj degradation, thiab puas, tiv taus kub txog 752 ° F (400 degree). Lawv paub tias yog nplaim taws, ruaj, xis nyob, thiab yooj yim rau tu. Txawm li cas los xij, lawv tsis yog xim sai npaum li lwm cov ntaub ntawv thiab tuaj yeem hloov xim raws sijhawm. Meta-aramids feem ntau siv rau hauv cov khaub ncaws tua hluav taws thiab cov khaub ncaws uas muaj nplaim taws vim lawv cov thermal stability thiab cov nplaim hluav taws kub (FR) cov khoom.

 

Para-aramid: Kev xaiv muaj zog thiab muaj zog
Para-aramids yog tsim los siv cov txheej txheem qhuav-txhaj tshuaj uas tsim cov crystalline fiber ntau nrog cov kua siv lead ua txuas ntxiv. Cov qauv no txhim kho lawv lub zog, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau lub zog tensile siab thiab tus cwj pwm modulus. Para-aramids yog cov tawv thiab muaj zog dua li cov meta-aramids, tab sis ntau dua rau cov tshuaj. Lawv yog siv rau hauv cov khoom siv foob pob hluav taws, kev siv tub rog thiab aerospace, thiab cov khoom siv kev nyab xeeb xws li hnab looj tes thiab kaus mom hlau. Txawm hais tias muaj zog ntawm para-aramids, lawv kuj ntsib cov teeb meem nrog cov xim tuav thiab tuaj yeem pom kev hnav thiab tsim kua muag thaum lub sijhawm.

 

Txoj Kev Xaiv Zoo rau Kev Nyab Xeeb
Thaum xaiv txoj cai aramid fiber ntau rau cov nplaim hluav taws kub nyhiab, cov kev cai tshwj xeeb ntawm daim ntawv thov yuav tsum raug txiav txim siab. Meta-aramids muaj kev ruaj khov thiab thermal stability rau qhov kub thiab txias, thaum para-aramids muaj qhov tsis sib haum xeeb thiab muaj zog, ua rau lawv zoo tagnrho rau ib puag ncig uas tiv thaiv lub cev tseem ceeb. Ob hom aramid fibers ua rau muaj txiaj ntsig zoo rau kev nyab xeeb thiab kev ua haujlwm ntawm cov khaub ncaws nplaim hluav taws, ua kom muaj kev tiv thaiv tiv thaiv flashover thiab tshuaj txau. Aramid fibers muaj qhov hnyav molecular thiab tuaj yeem siv los tsim cov khaub ncaws zoo nkauj thiab nyab xeeb, sib npaug tiv thaiv kev xav tau thiab hnav kev nplij siab.

 

Aramid fibers muaj cov khoom tshwj xeeb thiab kev hloov pauv, thiab yog ib feem tseem ceeb ntawm kev txhim kho cov nplaim hluav taws kub nyhiab, muab ntau yam kev daws teeb meem rau kev xav tau kev nyab xeeb sib txawv hauv qhov chaw muaj kev phom sij.
