Igama Lezinto: I-Aramid Fiber
Insimu Yesicelo
I-Aramid fiber uhlobo olusha lwe-high-tech synthetic fiber, amandla aphezulu kakhulu, i-modulus ephezulu kanye nokumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, isisindo esincane, izakhiwo ezinhle kakhulu, njenge-steel wire izikhathi ezi-5 ~ 6 kune-steel wire emandleni ayo, i-modulus ye-steel wire noma i-fiber glass izikhathi ezi-2 ~ 3, ukuqina kuphindwe kabili kwe-wire, kanti isisindo sicishe sibe yi-1/5 ye-steel wire, izinga lokushisa lingama-degrees angu-560, ungaphuki, ungancibiliki.
Inezakhiwo ezinhle zokuvikela ukuguga kanye nokuvikela ukuguga, futhi inomjikelezo wokuphila isikhathi eside. Ukutholakala kwe-aramid fiber kubhekwa njengenqubo yomlando ebaluleke kakhulu ezweni lezinto ezibonakalayo.
I-Aramid fiber iyinto ebalulekile yezempi yokuzivikela kwezwe. Ukuze kuhlangatshezwane nezidingo zempi yanamuhla, njengamanje, amajakethi angenazinhlamvu emazweni athuthukile njenge-United States ne-United Kingdom enziwe nge-aramid fiber. Ukukhanya kwamajakethi nezigqoko ezingenazinhlamvu ze-aramid fiber kuthuthukisa ngempumelelo ikhono lokuphendula okusheshayo kanye nokubulala kwamabutho empi. Empini yaseGulf, izindiza zaseMelika nezaseFrance zasebenzisa inani elikhulu lezinto ezihlanganisiwe ze-aramid. Ngaphezu kokusetshenziswa kwezempi, njengezinto ze-fiber zobuchwepheshe obuphezulu ziye zasetshenziswa kabanzi ezindiza, kwemishini nakugesi, ekwakheni, ezimotweni, ezintweni zemidlalo nakwezinye izici zomnotho wezwe. Ngokuphathelene nezindiza kanye nezindiza, i-aramid fiber isindisa uphethiloli omningi ngenxa yesisindo sayo esincane kanye namandla aphezulu. Ngokusho kwedatha yamazwe ngamazwe, ngesikhathi senqubo yokwethulwa kwezindiza, ukwehla kwesisindo ngakunye kwe-1 kg kusho ukwehla kwezindleko ze-1 million US dollars. Ngaphezu kwalokho, intuthuko esheshayo yesayensi nobuchwepheshe ivula indawo entsha yomphakathi ye-Aramid. Kubikwa ukuthi njengamanje, cishe u-7 ~ 8% wemikhiqizo ye-aramid isetshenziselwa amajakethi e-flak, izigqoko zokuzivikela, njll., kanti cishe u-40% usetshenziselwa izinto zezindiza nezinto zezemidlalo. Izinto zokwakheka kwamathambo amathayi, izinto zokubopha ibhande lokuthutha kanye nezinye izici ezingaba ngu-20%, kanye nentambo enamandla aphezulu kanye nezinye izici ezingaba ngu-13%.
Izinhlobo kanye Nemisebenzi ye-Aramid fiber: I-Para-Aramid fiber (PPTA) kanye ne-interaromatic amide fiber (PMIA)
Ngemva kwentuthuko ephumelelayo kanye nokuthuthukiswa kwe-aramid fiber yiDuPont ngawo-1960, eminyakeni engaphezu kwengu-30, i-aramid fiber idlule enkambisweni yokuguquka kusuka ezintweni zempi zamasu kuya ezintweni zomphakathi, futhi intengo yayo yehlisiwe cishe ngesigamu. Njengamanje, i-aramid fiber yangaphandle iyavuthwa kokubili ezingeni locwaningo kanye nentuthuko kanye nasekukhiqizweni kwesikali. Emkhakheni wokukhiqizwa kwe-aramid fiber, i-para aramide fiber iyona ekhula ngokushesha, lapho amandla ayo okukhiqiza egxile kakhulu eJapane, e-United States naseYurophu. Isibonelo, i-Kevlar evela e-dupont, i-Twaron fiber evela e-Akzo Nobel (ehlanganiswe ne-Teren), i-Technora fiber evela e-TeREN yaseJapan, i-Terlon fiber evela eRussia, njll.
Kukhona i-Nomex, i-Conex, i-Fenelon fiber njalo njalo. I-Dupont yase-United States iyiphayona ekuthuthukisweni kwe-aramid. Ihamba phambili emhlabeni kungakhathaliseki ukuthi icwaninga futhi ithuthukisa imikhiqizo emisha, imithetho yokukhiqiza kanye nesabelo semakethe. Njengamanje, i-Kevlar fibers yayo 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. Ukuze kungabonakali kudlulelwe yisikhathi, amabhizinisi aziwayo okukhiqiza i-aramid afana ne-Di Ren kanye ne-Hearst andise ukukhiqiza noma ahlangane, futhi ahlola ngenkuthalo imakethe, enethemba lokuba amandla amasha kule mboni ephumayo.
Inkampani yaseJalimane i-Acordis isanda kuthuthukisa imikhiqizo ye-contrapuntal aron (Twaron) esebenza kahle kakhulu, engashisi futhi engancibiliki, futhi enamandla aphezulu kanye nokumelana okukhulu kokusika, esetshenziswa kakhulu ekukhiqizweni kwezindwangu ezimboziwe nezingamboziwe, imikhiqizo elukiwe kanye ne-needle felt kanye neminye imishini yokushisa ephezulu kanye nokumelana nokusika yazo zonke izinhlobo zemishini yendwangu nezingubo. Ubunono besilika encane kakhulu ye-Twaron buyi-60% kuphela yobukhulu be-arylon ephikisanayo evame ukusetshenziswa ezimpahleni zokuphepha emsebenzini, futhi ingasetshenziswa ukwenza amagilavu. · Amandla ayo okulwa nokusika angathuthukiswa ngo-10%. Ingasetshenziswa ukukhiqiza izindwangu ezilukiwe kanye nemikhiqizo elukiwe, ngokuzwakala kwesandla okuthambile kanye nokusetshenziswa okukhululekile. Amagilavu e-Twaron okulwa nokusika asetshenziswa kakhulu embonini yokukhiqiza izimoto, embonini yengilazi kanye nabakhiqizi bezingxenye zensimbi. Angasetshenziswa futhi embonini yamahlathi ukukhiqiza imikhiqizo yokuvikela imilenze nokuhlinzeka ngemishini yokulwa nomonakalo embonini yezokuthutha zomphakathi.
Impahla kaTwaron yokuvimbela umlilo ingasetshenziswa ukuhlinzeka abacimi bomlilo ngamasudi okuzivikela kanye nezingubo zokulala zefelti, kanye neminyango yokusebenza eshisa kakhulu efana nokukhipha, isithando somlilo, ifektri yengilazi, njll., kanye nokukhiqizwa kwezinto zokubopha ezivimbela umlilo zezihlalo zezindiza. Le fibre esebenza kahle ingasetshenziswa futhi ukudala amathayi ezimoto, amapayipi okupholisa, ibhande le-V kanye neminye imishini, izintambo zefayibha ye-optical kanye namavesti avikela izinhlamvu kanye neminye imishini yokuvikela, kodwa futhi ingathatha indawo ye-asbestos njengezinto zokungqubuzana kanye nezinto zokuvala.
Isidingo Semakethe
Ngokwezibalo, isidingo somhlaba wonke se-aramid fiber singamathani angu-360,000 ngonyaka ngo-2001, futhi sizofinyelela amathani angu-500,000 ngonyaka ngo-2005. Isidingo somhlaba wonke se-aramid fiber sikhula njalo, futhi i-aramid fiber, njenge-fiber entsha esebenza kahle, isingene enkathini yentuthuko esheshayo.
