Fireproof fiber - aramid 1313 qauv.

Aramid 1313 yog thawj zaug ua tiav los ntawm DuPont hauv Tebchaws Meskas, thiab kev tsim khoom lag luam tau pom zoo hauv xyoo 1967, thiab cov khoom tau sau npe ua Nomex® (Nomex).Qhov no yog ib tug mos, dawb, slender, fluffy thiab lustrous fiber.Nws cov tsos yog tib yam li cov tshuaj fibers zoo tib yam, tab sis nws muaj qhov txawv txav "extraordinary functions":
Cov thermal stability.
Qhov tseem ceeb tshaj plaws ntawm aramid 1313 yog nws qhov kub thiab txias, uas tuaj yeem siv tau ntev ntawm 220 ℃ tsis muaj kev laus.Kev ua tau zoo ntawm nws cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tuaj yeem khaws cia rau 10 xyoo, thiab nws qhov kev ruaj ntseg zoo heev.Lub thermal shrinkage tus nqi ntawm li 1% tsuas yog 1%, thiab nws yuav tsis ntsws, embrittle, soften los yog yaj thaum raug kub ntawm 300 ° C rau ib lub sij hawm luv luv., xws li thermal stability yog qhov tshwj xeeb ntawm cov organic kub-resistant fibers tam sim no.
Cov nplaim retardancy zoo heev.
Peb paub tias qhov feem pua ​​​​ntawm cov pa oxygen xav tau rau cov khoom siv los hlawv hauv huab cua yog hu ua limiting oxygen index.Qhov loj dua qhov limiting oxygen index, qhov zoo dua nws cov nplaim retardant kev ua tau zoo.Feem ntau, cov pa oxygen hauv huab cua yog 21%, thiab qhov txwv cov pa ntsuas ntawm aramid 1313 yog ntau dua 28%.Cov yam ntxwv tseem ceeb no tau muab los ntawm nws tus kheej cov qauv molecular ua aramid 1313 mus tas li nplaim retardant, yog li nws muaj lub koob npe nrov ntawm "fireproof fiber".
Hluav taws xob rwb thaiv tsev zoo heev.
Aramid 1313 muaj qhov tsis tshua muaj dielectric tsis tu ncua, thiab nws cov khoom siv hluav taws xob muaj zog ua kom nws tswj tau cov hluav taws xob zoo hauv qhov kub thiab txias, tsis tshua muaj kub, thiab cov av noo siab.㎜, tau lees paub tias yog cov khoom siv insulating zoo tshaj plaws hauv ntiaj teb.
Zoo tshuaj stability.
Aramid 1313 yog linear macromolecule tsim los ntawm amide bonds txuas aryl pawg.Nyob rau hauv nws cov siv lead ua, hydrogen bonds yog teem nyob rau hauv ob lub dav hlau los tsim ib tug peb-dimensional qauv.Qhov no muaj zog hydrogen daim ntawv cog lus ua rau nws cov qauv tshuaj muaj zog heev thiab tuaj yeem tiv taus rau feem ntau cov concentrated inorganic acids thiab lwm yam tshuaj, hydrolysis thiab chav corrosion.
Zoo heev mechanical zog.
Aramid 1313 yog cov khoom siv polymer hloov tau nrog qhov tsis tshua muaj zog thiab siab elongation, ua rau nws zoo tib yam spinnability li qub fibers.Nws tuaj yeem ua tiav rau hauv ntau yam ntaub lossis cov ntaub tsis-woven los ntawm cov tshuab spinning, thiab nws yog hnav-resistant thiab tsim kua muag-resistant.dav heev.
Super hluav taws xob tsis kam.
Aramid 1313 muaj kev tiv thaiv zoo rau α, β, χ rays thiab ultraviolet hluav taws xob.Nrog 50Kv X-ray hluav taws xob rau 100 teev, lub zog fiber ntau tseem tshuav 73% ntawm qhov qub, thiab polyester lossis nylon nyob rau lub sijhawm no twb dhau los ua hmoov.Cov qauv tshuaj tshwj xeeb thiab ruaj khov endows aramid 1313 nrog cov khoom zoo heev.Los ntawm kev siv dav dav ntawm cov khoom no, cov haujlwm tshiab thiab cov khoom tshiab tau tsim kho tas li, thiab daim ntawv thov kev lag luam tau txais kev dav thiab dav, thiab cov koob meej tau nce siab dua.
Cov khaub ncaws tiv thaiv tshwj xeeb.
Aramid 1313 npuag tsis kub hnyiab, poob, yaj thiab haus luam yeeb thaum nws ntsib hluav taws, thiab muaj txiaj ntsig zoo heev.Tshwj xeeb tshaj yog thaum ntsib qhov kub ntawm 900-1500 ℃, daim ntaub saum npoo yuav tsum ceev ceev carbonized thiab thickened, tsim ib qho tshwj xeeb thermal rwb thaiv tsev thaiv los tiv thaiv cov neeg hnav los ntawm kev khiav tawm.Yog hais tias ib qho me me ntawm cov khoom siv hluav taws xob los yog aramid 1414 ntxiv, nws tuaj yeem tiv thaiv cov ntaub kom tawg thiab tsis txhob muaj kev phom sij ntawm xob laim arc, hluav taws xob arc, hluav taws xob zoo li qub, nplaim taws thiab lwm yam.Aramid 1313 non-ferrous fibers tuaj yeem siv los ua ntau yam kev tiv thaiv tshwj xeeb xws li davhlau suits, tshuaj tiv thaiv kev sib ntaus sib tua, hluav taws kub sib ntaus sib tua, lub tshuab hluav taws xob, hluav taws xob vuam zuag qhia tag nrho, lub zog sib npaug sib npaug, hluav taws xob pov thawj, tshuaj tiv thaiv suits, high-voltage shielding suits, thiab lwm yam. Aviation, aerospace, tub rog khaub ncaws, tiv thaiv hluav taws, petrochemical, hluav taws xob, roj, metallurgy, kev sib tw thiab ntau lwm yam.Tsis tas li ntawd, nyob rau hauv cov teb chaws tsim, aramid fabrics kuj tau lug siv nyob rau hauv tsev so textiles, txoj kev cawm seej, tsev neeg hluav taws-resistant decorations, ironing board npog, chav ua noj hnab looj tes, thiab nplaim taws-retardant pajamas los tiv thaiv cov neeg laus thiab cov me nyuam.
Cov khoom siv lim dej kub.
Qhov kub thiab txias tsis kam, qhov ruaj khov thiab cov tshuaj tiv thaiv ntawm aramid 1313 ua rau nws muaj zog nyob rau hauv lub tshav kub kub lim xov xwm.Aramid lim xov xwm yog dav siv nyob rau hauv tshuaj nroj tsuag, thermal fais fab nroj tsuag, carbon dub nroj tsuag, cement nroj tsuag, txiv qaub nroj tsuag, coking nroj tsuag, smelters, asphalt nroj tsuag, xim nroj tsuag, raws li zoo raws li kub-kub flues thiab cua kub nyob rau hauv hluav taws xob arc furnaces, roj boilers, thiab incinerators Lim tsis tau tsuas yog zoo tshem tawm cov plua plav, tab sis kuj tiv thaiv cov tshuaj tua kab mob ntawm cov pa phem, thiab nyob rau tib lub sij hawm pab txhawb kev rov qab los ntawm cov khoom muaj nqi hlau.
Honeycomb khoom siv.
Aramid 1313 structural material ntawv tuaj yeem siv los ua biomimetic ntau txheej honeycomb structural board, uas muaj lub zog zoo / qhov hnyav piv thiab rigidity / hnyav piv (li 9 npaug ntawm cov hlau), lub teeb yuag, cuam tshuam, nplaim taws, rwb thaiv tsev, thiab durability.Nws muaj cov yam ntxwv ntawm corrosion kuj, aging kuj thiab zoo electromagnetic yoj permeability.Nws yog qhov tsim nyog rau kev tsim cov khoom siv broadband nthwv dej thiab cov khoom siv loj hauv nruab nrab ntawm kev ntxhov siab ntawm cov dav hlau, cov cuaj luaj thiab satellites (xws li tis, fairings, cabin linings, qhov rooj, thiab lwm yam).Pem teb, cargo tuav thiab muab faib phab ntsa, thiab lwm yam), kuj haum rau zus tau tej cov yachts, sib tw nkoj, high-ceev tsheb ciav hlau thiab lwm yam high-kev ua tau zoo sandwich lug.
