Khoom npe: Aramid Fiber
Daim ntawv thov teb
Aramid fiber ntau yog ib hom tshiab ntawm high-tech hluavtaws fiber, ultra-siab zog, siab modulus thiab kub resistant, acid thiab alkali tsis kam, lub teeb yuag, zoo heev zog, xws li 5 ~ 6 npaug ntawm steel hlau ntawm nws lub zog, modulus steel hlau los yog fiber ntau iav 2 ~ 3 zaug, toughness yog 2 zaug ntawm hlau, thiab qhov hnyav tsuas yog li 1/5 ntawm cov hlau hlau, qhov kub ntawm 560 degrees, tsis txhob tawg, tsis yaj.
Nws muaj cov rwb thaiv tsev zoo thiab tiv thaiv kev laus, thiab muaj lub neej ntev.Kev tshawb pom ntawm aramid fiber ntau yog suav tias yog txheej txheem keeb kwm tseem ceeb hauv ntiaj teb cov khoom.
Aramid fiber ntau yog cov khoom siv tub rog tseem ceeb rau kev tiv thaiv hauv tebchaws.Yuav kom ua tau raws li qhov xav tau ntawm kev ua tsov rog niaj hnub no, tam sim no, cov tsho tiv thaiv mos txwv ntawm cov teb chaws tsim kho xws li Tebchaws Meskas thiab United Kingdom yog ua los ntawm aramid fiber ntau.Lub lightness ntawm aramid fiber ntau bulletproof tsho thiab kaus mom hlau zoo txhim kho cov tshuaj tiv thaiv sai thiab kev tuag ntawm cov tub rog rog.Nyob rau hauv Gulf Tsov Rog, Asmeskas thiab Fabkis cov dav hlau siv ntau cov ntaub ntawv aramid sib xyaw.Ntxiv nrog rau kev siv tub rog, raws li cov khoom siv high-tech fiber ntau tau siv dav hauv aerospace, mechanical thiab hluav taws xob, kev tsim kho, tsheb, khoom siv ncaws pob thiab lwm yam ntawm kev lag luam hauv lub tebchaws.Nyob rau hauv cov nqe lus ntawm aviation thiab aerospace, aramid fiber txuag tau ntau lub zog roj vim nws lub teeb yuag thiab siab zog.Raws li cov ntaub ntawv thoob ntiaj teb, thaum lub sijhawm tso tawm ntawm lub dav hlau, txhua qhov kev txo qis ntawm 1 kg txhais tau tias txo tus nqi ntawm 1 lab US dollars.Tsis tas li ntawd, txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis tau qhib ntau qhov chaw pej xeem tshiab rau Aramid.Nws tau tshaj tawm tias tam sim no, kwv yees li 7 ~ 8% ntawm cov khoom siv aramid yog siv rau cov tsho flak, kaus mom hlau, thiab lwm yam, thiab li ntawm 40% yog siv rau cov khoom siv dav hlau thiab cov khoom ua si.Tire skeleton khoom, conveyor siv cov khoom siv thiab lwm yam ntawm li 20%, thiab siab zog hlua thiab lwm yam ntawm li 13%.
Hom thiab Kev Ua Haujlwm ntawm Aramid fiber ntau: Para-Aramid fiber (PPTA) thiab interaromatic amide fiber (PMIA)
Tom qab kev vam meej thiab kev lag luam ntawm aramid fiber ntau los ntawm DuPont hauv xyoo 1960, hauv ntau dua 30 xyoo, aramid fiber ntau tau dhau los ntawm cov txheej txheem ntawm kev hloov pauv ntawm cov khoom siv tub rog rau cov ntaub ntawv pej xeem, thiab nws cov nqi tau raug txo los ntawm ze li ntawm ib nrab.Tam sim no, txawv teb chaws aramid fibers yog maturing ob qho tib si nyob rau hauv kev tshawb fawb thiab kev loj hlob theem thiab nyob rau hauv scale ntau lawm.Nyob rau hauv lub tshav pob ntawm aramid fiber ntau lawm, para aramide fiber yog qhov loj hlob sai tshaj plaws, nrog nws cov peev xwm ntau lawm mas concentrated nyob rau hauv Nyiv, Tebchaws Asmeskas thiab Europe.Piv txwv li, Kevlar los ntawm dupont, Twaron fiber los ntawm Akzo Nobel (ua ke nrog Teren), Technora fiber los ntawm TeREN ntawm Nyiv, Terlon fiber los ntawm Russia, thiab lwm yam.
Muaj Nomex, Conex, Fenelon fiber ntau thiab lwm yam.Dupont ntawm lub tebchaws United States yog ib tug pioneer nyob rau hauv txoj kev loj hlob ntawm aramid.Nws nyob qib thawj hauv ntiaj teb tsis muaj teeb meem hauv kev tshawb fawb thiab kev tsim cov khoom tshiab, cov cai ntau lawm thiab kev ua lag luam.Tam sim no, nws cov Kevlar fibers muaj ntau tshaj 10 hom, xws li Kevlar 1 49 thiab Kevlar 29, thiab txhua hom muaj ntau ntau yam specifications.Dupont tshaj tawm xyoo tas los hais tias nws yuav nthuav nws Kevlar muaj peev xwm tsim tau, thiab qhov kev nthuav dav yuav tsum ua kom tiav thaum kawg ntawm lub xyoo no.Tsis yog yuav tsum tau outdone, paub zoo aramid ntau lawm qhauj xws li Di Ren thiab Hearst tau nthuav ntau lawm los yog koom nrog rog, thiab nquag tshawb nrhiav kev lag luam, vam tias yuav dhau los ua lub zog tshiab hauv kev lag luam hnub ci.
Lub tuam txhab German Acordis tsis ntev los no tau tsim cov khoom ua tau zoo ultrafine contrapuntal aron (Twaron) cov khoom, uas tsis hlawv los yog yaj, thiab muaj lub zog siab thiab zoo txiav tsis kam, feem ntau yog siv los tsim cov coated thiab uncoated fabrics, knitted khoom thiab koob xav thiab lwm yam siab. - Kub thiab txiav tsis kam ntawm txhua yam khoom siv textile thiab khaub ncaws.Qhov zoo ntawm Twaron super nyias txhob lo lo ntxhuav tsuas yog 60% ntawm cov counterpoint arylon feem ntau siv hauv kev ua haujlwm kev nyab xeeb, thiab nws tuaj yeem siv los ua hnab looj tes.· Nws muaj peev xwm tiv thaiv kev txiav tuaj yeem txhim kho los ntawm 10%.Nws tuaj yeem siv los tsim cov ntaub npuag thiab cov khoom knitted, nrog softer tes xav thiab siv tau zoo dua.Twaron anti-txiav hnab looj tes yog tsuas yog siv nyob rau hauv tsheb tsim kev lag luam, iav kev lag luam thiab hlau qhov chaw manufacturers.Lawv kuj tuaj yeem siv rau hauv kev lag luam hav zoov los tsim cov khoom tiv thaiv ceg thiab muab cov cuab yeej tiv thaiv kev puas tsuaj rau kev lag luam tsheb thauj mus los rau pej xeem.
Twaron cov khoom siv hluav taws xob hluav taws xob tuaj yeem siv los muab cov hluav taws tua hluav taws nrog cov khoom tiv thaiv thiab cov pam vov, nrog rau cov chaw ua haujlwm kub kub xws li casting, furnace, iav Hoobkas, thiab lwm yam, nrog rau kev tsim cov khoom siv hluav taws kub retardant cladding rau cov rooj zaum dav hlau.Qhov kev ua tau zoo fiber ntau no tseem tuaj yeem siv los tsim cov tsheb log tsheb, txias hoses, V-siv thiab lwm yam tshuab, fiber ntau optical cables thiab cov tsho tiv thaiv mos txwv thiab lwm yam khoom siv tiv thaiv, tab sis kuj tuaj yeem hloov cov asbestos ua cov ntaub ntawv sib txhuam thiab cov khoom sib khi.
Kev Ua Lag Luam
Raws li kev txheeb cais, lub ntiaj teb tag nrho cov kev xav tau ntawm aramid fiber ntau yog 360,000 tons / xyoo hauv xyoo 2001, thiab yuav ncav cuag 500,000 tons / xyoo hauv 2005. Lub ntiaj teb kev thov rau aramid fiber ntau yog nce ntxiv, thiab aramid fiber ntau, raws li cov khoom siv fiber ntau tshiab. , tau nkag mus rau lub sijhawm ntawm kev loj hlob sai.
