Aramid 1414 yog dab tsi? Dab tsi yog cov yam ntxwv ntawm Aramid 1414? Yuav luag tib lub sijhawm raws li kev tsim tawm ntawm Aramid 1313, DuPont tau tsim lwm cov khoom siv hluavtaws, Aramid 1414 thaum xyoo 1960s. Cov khoom lag luam tau nthuav tawm thawj zaug hauv xyoo 1972 thiab muaj npe Kevlar®.
Aramid 1414 muaj ib tug golden tsos thiab zoo li ib tug ci iab hlau hlau, tab sis nws yog tiag tiag ib tug kua siv lead ua polymer uas muaj xws li ntev, nyuaj molecules. Nws cov saw hlau molecular yog qhov taw qhia ntawm nws qhov ntev, thiab lub zog ruaj khov ntawm cov saw hlau muab lub zog fiber ntau uas tsis tau pom dua, siab modulus thiab kub tsis kam.
Qhov kev tshawb pom ntawm Aramid 1414 yog suav tias yog lub hauv paus tseem ceeb hauv kev txhim kho cov khoom lag luam. Lub zog ntawm Aramid 1414 yog siab heev, tshaj 28g / d, uas yog 5-6 npaug ntawm cov hlau zoo, 2-3 npaug ntawm cov hlau los yog iav fiber ntau, ob npaug ntawm cov hlau, thiab hnyav tsuas yog hlau. 1/5. (Lub toughness ntawm Aramid 1414 kuj ua rau txiav nyuaj heev, yuav tsum tau kim tshwj xeeb cov cuab yeej).
Aramid 1414 muaj qhov dav txuas ntxiv ua haujlwm kub ntau yam. Nws tuaj yeem ua haujlwm ib txwm siv sijhawm ntev hauv thaj tsam ntawm -196 ℃ ~ 204 ℃. Nws muaj qhov shrinkage ntawm 0 ntawm 150 ℃. Nws tsis decompose los yog yaj ntawm qhov kub ntawm 560 ° C. Nws muaj kev ua tau zoo dua li aramid 1313. Lub tshav kub tsis kam, zoo heev rwb thaiv tsev thiab corrosion kuj, thiab lub neej ntev. Muaj lub koob npe nrov ntawm" hluavtaws hlau hlau".
Aramid 1414 yog thawj zaug siv nyob rau hauv frontier teb xws li lub teb chaws tiv thaiv thiab tub rog kev lag luam. Cov tub rog thiab tub ceev xwm hauv Tebchaws Meskas, Russia, United Kingdom, Lub Tebchaws Yelemees, Fabkis, Israel, Ltalis thiab ntau lub tebchaws siv cov tsho tiv thaiv mos txwv. Bulletproof vests ua tau raws li qhov xav tau ntawm kev ua tsov rog niaj hnub no thiab kev tiv thaiv kev ua phem. Cov kaus mom hlau, cov khaub ncaws hnav thiab khawb-tiv taus, EOD suits, thiab lub zog muaj zog parachutes, mos txwv tsho khuam. Aramid 1414 yog dav siv nyob rau hauv lub tsheb lub cev thiab armor daim hlau. Nyob rau hauv lub cev armor, aramid fiber ntau muaj zog, toughness thiab zoo heev weaving, yog li nws absorbs lub zog ntawm cov mos txwv thiab hloov mus rau lwm woven fibers kom tsis txhob" blunt scratches" thiab txhim khu kev tiv thaiv. .. .. Aramid lub cev armor thiab kaus mom hlau yog lub teeb nyob rau hauv qhov hnyav, uas zoo txhim kho cov tub rog cov lus teb sai thiab muaj peev xwm tiv thaiv.
Niaj hnub no, ntxiv rau kev lag luam tub rog, Aramid 1414 yog cov khoom siv high-tech textile uas tau siv dav hauv txhua yam ntawm kev lag luam hauv lub tebchaws, suav nrog aerospace, motors, kev tsim kho, tsheb, khoom siv hauv hiav txwv, thiab cov khoom ua si.
Hauv thaj chaw aerospace, aramid fiber ntau resin-raws li cov ntaub ntawv sib xyaw ua ke yog siv los ua cov khoom siv rau hauv aerospace, foob pob hluav taws thiab dav hlau kom txo qhov hnyav, nce load, thiab txuag hluav taws xob thiab roj ntau. Piv txwv li, lub plhaub sab nrauv, sab hauv thiab lub rooj zaum ntawm Boeing aircraft tau ua tiav siv Aramid 1414 cov khoom, txo qhov hnyav los ntawm 30%.
Aramid 1414 muaj tsawg ceev, siab zog, siab kub kuj thiab yav tom ntej adhesion rau roj hmab, ua rau nws lub feem ntau zoo tagnrho qaum fiber. Aramid cords txo lub thickness ntawm lub log, txo qhov hnyav, ua kom yooj yim rau dissipate tshav kub, txo deformation, txo dov tsis kam, txhim kho kev tsav tsheb ceev, ncua lub log tsheb kev pab cuam lub neej, thiab txhim kho puncture resistance. Vim nws cov yam ntxwv, nws yog ib qho yooj yim rau punctured tom qab puncture, thiab nws yuav tsum tau tsav mus rau hauv lub chaw nres tsheb yam tsis muaj kev puas tsuaj rau sab ntawm lub log tsheb. Aramid 1414 yog qhov tshwj xeeb tshaj yog tsim rau kev siv cov hlua khi hlua khi hauv cov tsheb loj lossis cov tsheb loj thiab dav hlau, thiab muaj kev cia siab rau kev loj hlob. Niaj hnub no, lub ntiaj teb no' tus thawj log tsheb loj xws li Michelin, Goodyear, thiab Pirelli yog siv Aramid 1414 raws li lub log tsheb code, uas yog dav siv nyob rau hauv cov khoom kim heev tsheb teb.
Nyob rau hauv civil engineering, Aramid 1414 muaj cov yam ntxwv ntawm lub teeb yuag, siab zog, siab elastic modulus, corrosion kuj, non-conductivity, thiab tej yam kuj. Nws tuaj yeem siv rau hauv cov choj, ncej, subways, chimneys, dej yees, thiab lwm yam, tunnels, electrified railways thiab ports. Lub wharf tau kho thiab ntxiv dag zog, uas yog tshwj xeeb tshaj yog haum rau kev kho thiab kho cov pob zeb ua vaj tse.
Tsis tas li ntawd, Aramid 1414 kuj tuaj yeem siv los ua cov khoom siv pob txha rau cov khoom siv roj hmab inflatable (inflatable life rafts, inflatable bridges, etc.), cov thawv uas tsis muaj zog, cov roj tank thiab cov kav dej loj loj. Siv los ua cov hnab looj tes tiv thaiv kev kub ntxhov. Nrog nws tus kheej-lubricity, kub ua hauj thiab toughness, nws muaj peev xwm hloov carcinogenic asbestos nyob rau hauv lub tshav kub shields, tiv thaiv khaub ncaws thiab sealants. Nws tuaj yeem hloov tau asbestos thiab iav fiber reinforced plastics. Kev tiv thaiv kev sib txhuam, rwb thaiv tsev thiab hluav taws xob rwb thaiv tsev.
