Igama Lempahla: I-Aramid Fiber
Inkambu yohlelo lokusebenza
I-Aramid fiber iwuhlobo olusha lwe-high-tech fiber synthetic, amandla aphezulu kakhulu, i-modulus ephezulu nokumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, isisindo esilula, izakhiwo ezinhle kakhulu, njenge-5 ~ 6 izikhathi zocingo lwensimbi emandleni ayo, I-modulus yocingo lwensimbi noma ingilazi ye-fiber 2 ~ 3 izikhathi, ukuqina izikhathi ezingu-2 zocingo, futhi isisindo simayelana ne-1/5 yocingo lwensimbi, izinga lokushisa lama-degree angu-560, ungaphuli, ungancibiliki.
Ine-insulation enhle kanye nezindawo zokulwa nokuguga, futhi inomjikelezo wempilo ende.Ukutholakala kwe-aramid fiber kuthathwa njengenqubo yomlando ebaluleke kakhulu emhlabeni wezinto ezibonakalayo.
I-Aramid fiber iyimpahla ebalulekile yezempi yokuvikela izwe.Ukuze kuhlangatshezwane nezidingo zempi yesimanje, okwamanje, amajakhethi angangenwa izinhlamvu emazweni athuthukile njenge-United States ne-United Kingdom enziwe nge-aramid fiber.Ukukhanya kwamajakhethi we-aramid fiber bulletproof nezigqoko kuthuthukisa ngempumelelo ikhono lokusabela ngokushesha kanye nobungozi bamabutho ezempi.Empini yaseGulf, izindiza zaseMelika nezaseFrance zasebenzisa inani elikhulu lezinto ezihlanganisiwe ze-aramid.Ngaphezu kwezicelo zezempi, njenge-high-tech fiber material iye yasetshenziswa kabanzi ku-aerospace, mechanical kanye nogesi, ukwakhiwa, izimoto, izimpahla zezemidlalo kanye nezinye izici zomnotho wezwe.Mayelana nezokundiza kanye ne-aerospace, i-aramid fiber yonga uphethiloli wamandla amaningi ngenxa yesisindo sayo esilula namandla ayo aphezulu.Ngokusho kwedatha yamazwe ngamazwe, phakathi nenqubo yokwethulwa kwemikhumbi-mkhathi, konke ukunciphisa isisindo nge-1 kg kusho ukwehla kwezindleko zamaRandi ayizigidi ezingu-1.Ngaphezu kwalokho, ukuthuthuka okusheshayo kwesayensi nobuchwepheshe kuvula indawo entsha yomphakathi ye-Aramid.Kubikwa ukuthi okwamanje, cishe i-7 ~ 8% yemikhiqizo ye-aramid isetshenziselwa amajakhethi e-flak, izigqoko zokuzivikela, njll., futhi cishe i-40% isetshenziselwa izinto ze-aerospace nezinto zezemidlalo.Impahla yamathambo ethaya, impahla yebhande lokudlulisa nezinye izinto ezingaba ngu-20%, nentambo enamandla amakhulu nezinye izici ezingaba ngu-13%.
Izinhlobo nemisebenzi ye-Aramid fiber: I-Para-Aramid fiber (PPTA) ne-interaromatic amide fiber (PMIA)
Ngemuva kwentuthuko eyimpumelelo kanye nezimboni ze-aramid fibre yi-DuPont ngeminyaka yawo-1960, eminyakeni engaphezu kwengama-30, i-aramid fiber isidlulile ohlelweni lokusuka ezintweni zamasu ezempi kuya ezintweni ezisetshenziswa umphakathi, futhi inani layo lehliswe cishe ngesigamu.Njengamanje, imicu ye-aramid yangaphandle iyakhula kokubili ezingeni locwaningo nentuthuko kanye nokukhiqizwa kwezikali.Emkhakheni wokukhiqizwa kwefayibha ye-aramid, i-para aramide fiber ikhula ngokushesha kakhulu, amandla ayo okukhiqiza agxile kakhulu eJapan, e-United States naseYurophu.Isibonelo, u-Kevlar wase-dupont, i-Twaron fiber evela ku-Akzo Nobel (ehlanganiswe ne-Teren), i-Technora fiber evela e-TeREN yaseJapane, i-Terlon fiber yaseRussia, njll.
Kukhona amaNomex, Conex, Fenelon fiber nokunye.UDupont wase-United States uyingqalabutho ekuthuthukisweni kwe-aramid.Ikleliswa kuqala emhlabeni kungakhathalekile ocwaningweni nasekuthuthukisweni kwemikhiqizo emisha, imithetho yokukhiqiza kanye nesabelo semakethe.Njengamanje, imicu yayo ye-Kevlar inezinhlobo ezingaphezu kwe-10, njenge-Kevlar 1 49 kanye ne-Kevlar 29, futhi uhlobo ngalunye lunemininingwane eminingi.I-Dupont yamemezela ngonyaka odlule ukuthi izokwandisa amandla ayo okukhiqiza i-Kevlar, futhi iphrojekthi yokwandisa kulindeleke ukuthi iqedwe ekupheleni kwalo nyaka.Akumele kudlulelwe phambili, amabhizinisi aziwayo okukhiqiza ama-aramid afana no-Di Ren no-Hearst andise ukukhiqiza noma ahlanganisa amandla, futhi ahlola imakethe ngenkuthalo, ngethemba lokuba amandla amasha kulo mkhakha wokuphuma kwelanga.
Inkampani yaseJalimane i-Acordis isanda kuthuthukisa imikhiqizo ye-ultrafine contrapuntal aron (Twaron) esebenza kahle kakhulu, engashi noma incibilike, futhi ibe namandla aphezulu kanye nokumelana okukhulu nokusika, esetshenziswa ikakhulukazi ekukhiqizeni izindwangu ezimboziwe nezingagqokile, imikhiqizo elukiwe kanye nenaliti ezwakalayo nokunye okuphezulu. -izinga lokushisa nokusika ukumelana kwazo zonke izinhlobo zemishini yendwangu nezingubo.Ubucwebe be-Twaron super thin kasilika ingama-60% kuphela yaleyo ye-arylon ephikisanayo evame ukusetshenziswa kumasudi okuphepha emsebenzini, futhi ingasetshenziswa ukwenza amagilavu.· Ikhono layo lokulwa nokusika lingathuthukiswa ngo-10%.Ingasetshenziselwa ukukhiqiza izindwangu ezilukiwe kanye nemikhiqizo elukiweyo, ngokuzwakala kwesandla esithambile nokusebenzisa ngokunethezeka.Amagilavu e-Twaron anti-cutting asetshenziswa kakhulu embonini yokukhiqiza izimoto, imboni yengilazi kanye nabakhiqizi bezingxenye zensimbi.Angasetshenziswa futhi embonini yamahlathi ukukhiqiza imikhiqizo yokuvikela imilenze futhi ahlinzeke ngezinto zokulwa nomonakalo embonini yezokuthutha zomphakathi.
Impahla ye-Twaron evimbela umlilo ingasetshenziselwa ukuhlinzeka izicishamlilo ngamasudi okuzivikela kanye nezingubo zokulala ezizwakalayo, kanye neminyango yokusebenza kwezinga lokushisa eliphezulu njengokuphonsa, isithando somlilo, ifektri yengilazi, njll.Le fibre esebenza kahle ingase futhi isetshenziselwe ukwakha amathayi ezimoto, amapayipi okupholisa, ibhande le-V kanye neminye imishini, izintambo ze-fiber optical namavesti angangenwa izinhlamvu nezinye izinto zokuzivikela, kodwa futhi ingangena esikhundleni se-asbestos njengezinto zokungqubuzana nezinto zokuvala.
Isidingo Semakethe
Ngokwezibalo, isidingo emhlabeni wonke se-aramid fiber singamathani angu-360,000/ngonyaka ngo-2001, futhi sizofinyelela amathani angu-500,000/ngonyaka ngo-2005. , ingene esikhathini sokuthuthuka okusheshayo.
