I-carbon fiber izwakele
Isingeniso
I-Carbon kanye ne-Graphite ezwakele iwukushisa okuthambile okuguquguqukayo kwe-high-temperature refractory okuvamise ukusetshenziswa endaweni engenalutho nendawo evikelekile efinyelela ku-5432℉ (3000℃). Ukuhlanzeka okuphezulu kuzwakale kuphathwe ukushisa kufika ku-4712℉(2600℃) kanye ne-Halogen Purification kuyatholakala ngama-oda okukhiqiza ngokwezifiso. Ukwengeza, impahla ingasetshenziswa emazingeni okushisa oxidizing afika ku-752℉ (400℃).
Ifomu le-carbon fiber elicushiwe lizwakala kakhulu, indwangu, imicu, ne-fiber yemifino (i-viscose fiber) noma enye i-polymer ephilayo njengezinto zokusetshenziswa, ezakheke kuqala bese zisebenza nge-carbonized.Isici esiyinhloko yikhabhoni. Ama-athomu ekhabhoni akhona ngendlela yokunqwabelana okungahleliwe kwama-microcrystals afana ne-graphite ku-carbon fiber ecushiwe. Ukuhleleka kwesikhala esinezinhlangothi ezintathu akulungile.
Esinye isici siwukuthi inendawo enkulu, futhi inani elikhulu lama-micropores avuliwe phezu kwefiber surface. Enqubweni yokukhangisa kanye ne-desorption, indlela ye-molecular adsorption imfushane, futhi i-adsorbent ingangena ngokuqondile kuma-micropores.Lokhu kunikeza izimo zokukhangisa okusheshayo kwe-activated carbon fiber kanye nokusetshenziswa okuphumelelayo kwama-micropores.
Indawo ethize ye-fiber activated carbon inkulu, ama-pores athuthukisiwe kahle, ukusebenza kwe-adsorption kuphezulu, isivinini se-desorption siyashesha, singasetshenziswa ngokuphindaphindiwe njalonjalo.
Uyini umehluko phakathi kwePan neRayon Felts?
I-Polyacrylonitrile, eyaziwa nangokuthi i-PAN, yakhiwe ngemicu yekhosi emikhulu yobubanzi okuholela endaweni ephansi kanye nokumelana ne-oxidation okungcono. Izinto eziguquguqukayo ziqinile futhi zithambile kancane lapho uzithinta uma kuqhathaniswa neRayon. I-Thermal conductivity ye-Rayon iphansi kune-PAN emazingeni okushisa angaphezu kuka-3272℉ (1800℃).
Mayelana nezicelo zokwelapha ukushisa, ihhovisi lethu lincoma kakhulu i-PAN carbon ezwakalayo ngenxa yokuphatha kalula kanye nentengo encishisiwe. Uma usebenza emazingeni okushisa angaphezu kuka-3272℉ (1800℃), sicela usebenzise iRayon.
IZINZUZO
Kulula ukusika nokufaka.
Ukuminyana okuphansi kanye nesisindo esishisayo.
Ukumelana nokushisa okuphezulu.
Umlotha ophansi nesibabule okuqukethwe.
Akukho ukukhipha.
Isicelo
(1) ukuvuselelwa kwe-solvent: i-benzene, i-ketone, i-ester, uwoyela kungaba ukutakula kwe-adsorption.
(2) ukuhlanzwa komoya: kungamunca futhi kuhlunge umoya ephunga, iphunga lomzimba, intuthu, igesi, O3, SO2, NO.
(3) ukuhlanzwa kwamanzi: kungasusa ama-ion ensimbi esindayo emanzini, izinto ezibangela umdlavuza, iphunga, isikhunta, amagciwane kanye ne-decolorization; Ingasetshenziselwa ukwelapha amanzi ompompi, amanzi embonini yokudla kanye namanzi ahlanzekile ezimbonini.
(4) ubunjiniyela bezemvelo: igesi engcolile kanye nokuphathwa kwendle;
(5) izinto zokuphefumula, izingubo zokuzivikela, izisefo zikagwayi, njll.;
6 ukukhishwa kwensimbi eyigugu noma ukutholwa, i-adsorption yezinto ezinomsakazo, kungasetshenziswa futhi njengesithwali se-catalyst, isigaba segesi se-chromatography;
Imithi ephaketheni, i-antidote eyingozi, izinso zokwenziwa, njll.;
E. Izinhlelo zokusebenza zikagesi namandla, njengama-capacitor omthamo omkhulu, amabhethri okugcina, njll.;
Izinga lokushisa eliphezulu kanye nezinto zokufakelwa.
Ocushiwe carbon fibre ngokusho impahla ingahlukaniswa viscose, polyacrylonitrile ezimbili uchungechunge, ngokusho ifomu:
● i-carbon fiber esebenzayo izwakele ● indwangu ye-carbon fibre ecushiwe
● i-carbon fiber ecushiwe ● i-activated carbon fiber paper
