I-Graphite enwebekayo iyinhlanganisela ye-graphite intercalation ephathwa ngokukhethekile equkethe ama-acid noma ama-oxidizing agents afakwe phakathi kwezingqimba ze-graphite, futhi uma ivezwa ekushiseni okuthile kokusebenza, ama-interlayer compounds abola ngokushesha, ekhipha umthamo omkhulu wegesi ophoqa isakhiwo se-graphite ukuthi sande kakhulu eceleni kwe-c-axis, sakhe into efana ne-worm, enezimbobo eyaziwa ngokuthi i-expanded graphite, esetshenziswa kabanzi ezinhlelweni zokuvimbela umlilo, izinto zokuvala, ukuvikela ukushisa, kanye nezicelo zobunjiniyela bezimboni.

Ngokungafani ne-natural flake graphite noma i-microcrystalline graphite esetshenziswa ekusetshenzisweni kwensimbi noma ekugcotshweni, i-graphite enwebekayo ayibalulekile kakhulu ngokuqukethwe kwayo kwekhabhoni kuphela kodwa nangendlela yayo yokukhulisa eyingqayizivele, eguqula isakhiwo esinezingqimba ezijiyile sibe yinto enwebeka kakhulu, enobukhulu obuphansi, nendawo ephezulu enezakhiwo ezintsha zomzimba ngokuphelele.

Ukuqonda i-graphite enwebekayo kudinga ukugxila endleleni yayo yokuguqula, indlela yokucubungula izimboni, kanye nezinzuzo zokusebenza ezikunikezayo ngemva kokunwetshwa, ikakhulukazi ezinhlelweni zokuphepha ezishisa kakhulu kanye nobunjiniyela bezinto ezithuthukisiwe.

Kanjanii-graphite enwebekayoiyanda ngaphansi kokusebenza kokushisa

Isici esiyinhloko se-graphite enwebekayo ukusabela kwayo kokukhula kokushisa, okwenzeka lapho amakhemikhali ahlanganisiwe phakathi kwezingqimba ze-graphite efinyelela izinga lokushisa lokubola futhi ekhiqiza ingcindezi yegesi ngaphakathi kwesakhiwo sekristalu.

● Izinhlanganisela ze-intercalation ziphuka ngokushesha lapho zishisa
● Igesi elikhulu likhishwa phakathi kwezingqimba ze-graphite
● Ingcindezi yangaphakathi iphoqa izendlalelo ze-graphite ukuthi zihlukane eceleni kwe-crystal axis
● Izinto zanda zibe isakhiwo esifana nesibungu noma esimise okwe-accordion

Le nqubo ishesha kakhulu futhi ayinakuguqulwa, okusho ukuthi uma kwenzeka ukwanda, isakhiwo se-graphite sishintsha unomphela sibe yi-graphite enwetshiwe enevolumu ekhuphukile kakhulu kanye nendawo engaphezulu.

Ukuguqulwa kwesakhiwo kusuka ku-graphite ehlanganisiwe kuya ku-graphite enwetshiwe

Ngaphambi kokunwetshwa, i-graphite enwebekayo ibonakala njengento ehlanganisiwe enezingqimba lapho izinto zamakhemikhali zifakwa khona phakathi kwezindiza ze-graphite, kodwa ngemva kokusebenza kokushisa, isakhiwo sishintsha kakhulu sibe yinto enezimbobo, enobukhulu obuphansi.

● Umthamo unganda izikhathi eziningi uma kuqhathaniswa nosayizi wokuqala we-graphite
● Ubuningi buncipha kakhulu ngemva kokukhula
● Indawo engaphezulu iyanda kakhulu ngenxa yokuhlukaniswa kwezingqimba
● Izakhiwo ezinezimbobo ezinokuqina okuphezulu kanye nokuguquguquka

Lolu shintsho yilona isizathu esenza i-graphite enwetshiwe iziphathe ngendlela ehluke kakhulu ezintweni ze-graphite zendabuko ezisetshenziswa ezimbonini.

Kungani i-graphite enwebekayo ibalulekile ekusetshenzisweni kwezimboni

I-graphite enwebekayo isetshenziswa kabanzi ezimbonini ezidinga izinto zokusebenza okuphezulu ezikwazi ukuphendula ezidingweni zokushisa, ingcindezi, kanye nokuvala, ikakhulukazi ezinhlelweni ezibalulekile zokuphepha lapho ukumelana nomlilo kanye nokufakwa kokushisa kubalulekile khona.

● Inikeza ukusebenza okuhle kakhulu kokuvimbela ilangabi ezinhlelweni ze-polymer

Ngenxa yalezi zakhiwo, i-graphite enwebekayo isetshenziswa kabanzi kubunjiniyela bokuphepha komlilo, izinto zokwakha, kanye nobuchwepheshe bokuvala izimboni.

Ukusetshenziswa ezinhlelweni zokuvikela umlilo ezivimbela ilangabi

Enye yezindlela ezibaluleke kakhulu zokusebenzisa i-graphite enwetshiwe isetshenziswa ezintweni ezivimbela ilangabi, lapho indlela yayo yokukhulisa isiza khona ukudala isithiyo esivikelayo ngesikhathi sokuchayeka emlilweni.

● Iyanwebeka ngaphansi kokushisa ukuze yakhe ungqimba lwekhabhoni oluvikelayo
● Kuvimba umoya-mpilo kanye nokudluliselwa kokushisa ezintweni ezingaphansi
● Kunciphisa ukusabalala komlilo kuma-polymers nezinto ezihlanganisiwe
● Kuthuthukisa ukusebenza kokuphepha komlilo ezintweni zokwakha

Ivame ukusetshenziswa ezimbozweni ezingashi, izithasiselo zepulasitiki, izintambo, kanye namabhodi okuvikela lapho kudingeka khona ukuvikelwa komlilo okungenamsebenzi.

Indima embonini yokubopha kanye nokukhiqiza ama-gasket

I-graphite enwetshiwe isetshenziswa kabanzi nasezinhlelweni zokuvala ezisebenza kahle ngenxa yokucindezelwa kwayo, ukuguquguquka kwayo, kanye nokumelana nezimo zokushisa ezibucayi.

● Yakha amashidi okuvala aqinile kakhulu futhi acindezeleka kahle kakhulu
● Ivumelana nezimo ze-flange ezingajwayelekile ukuze ivalwe ngendlela ethembekile
● Igcina ukusebenza kahle ngaphansi kwezimo zokushisa eziphakeme kanye nemijikelezo yokucindezela
● Ayimelani nokugqwala kwamakhemikhali ezindaweni zezimboni

Lezi zakhiwo zenza kube yinto ebalulekile ekukhiqizeni ama-gasket ezitshalweni ze-petrochemical, iziteshi zikagesi, kanye nezinhlelo zamapayipi ezimboni.

Ukufakwa kokushisa kanye nezicelo zobunjiniyela ezisebenzisa izinga lokushisa eliphezulu

Ngenxa yesakhiwo sayo esinezimbobo kanye nokushisa okuphansi, i-graphite enwetshiwe isetshenziswa kabanzi ezinhlelweni zokuvikela ukushisa lapho ukuphathwa kokushisa kubaluleke kakhulu.

● Kunciphisa ukudluliselwa kokushisa ezithandweni zezimboni kanye naseziphehlini
● Ihlinzeka ngezixazululo zokuvikela ezilula zezinhlelo zokushisa okuphezulu
● Kuthuthukisa ukusebenza kahle kwamandla ezinqubweni zokushisa eziqhubekayo
● Igcina ukuqina kwesakhiwo ngaphansi kwezimo zokushisa okukhulu

Lokhu kwenza ifaneleke imishini yezimboni ethuthukisiwe lapho kudingeka khona kokubili ukuvikelwa kokushisa kanye nokuthembeka kwemishini.

Izinzuzo zezinto ezibonakalayo ze-graphite enwetshiwe

I-graphite enwetshiwe inikeza inhlanganisela eyingqayizivele yezakhiwo zomzimba nezamakhemikhali ezihlukanisa nezinto ezivamile zekhabhoni.

● Indawo ephezulu kakhulu ngenxa yokwanda okunezingqimba
● Ubuningi obuphansi obunokucindezeleka okuphezulu kanye nokuguquguquka
● Ukumelana okuhle kakhulu nokushisa ezindaweni ezishisa kakhulu
● Ukuqina kwamakhemikhali okuqinile ezimweni ezine-asidi ne-alkaline
● Ukuzivumelanisa nezimo okuhle kokuhlanganiswa kwezinto ezihlanganisiwe

Lezi zinzuzo zivumela ukuthi isetshenziswe emikhakheni eminingi yezimboni enezidingo zokusebenza ezahlukene.

Ukuguquguquka kokucubungula kwezimboni kanye namafomu omkhiqizo

Ngemva kokunwetshwa, i-graphite ingacutshungulwa ibe imikhiqizo ehlukene yezimboni kuye ngezidingo zokusetshenziswa kanye nezidingo zokusebenza.

● Amashidi e-graphite aguquguqukayo okufaka izicelo zokuvala
● Izinto zokupakisha ze-graphite zamaphampu nama-valve
● Izithasiselo ezivimbela ilangabi zama-polymer namapulasitiki
● Amabhodi okushisa ashisayo nezinto ezihlanganisiwe

Lokhu kuguquguquka kwenza i-grafiti enwetshiwe ibe yinto ebaluleke kakhulu phakathi kwezinhlelo zokukhiqiza ezithuthukisiwe.

Kungani i-graphite enwebekayo ihlukile kwezinye izinhlobo ze-graphite

I-graphite enwebekayo akufanele ididaniswe ne-natural flake graphite noma i-microcrystalline graphite ngoba inani layo alisekelwe ekuhlanzekeni kwekhabhoni kodwa lisekelwe ekhonweni layo lokunwetshwa okulawulwayo.

● I-graphite yemvelo isetshenziswa kakhulu ekuqhubeni nasekusebenziseni izinsimbi
● I-Microcrystalline graphite isetshenziselwa ukusetshenziswa kwekhabhoni yezimboni ngobuningi
● I-graphite enwebekayo yenzelwe ngqo ukusebenza kokushisa kanye nokuguqulwa kwesakhiwo

Lo mehluko wokusebenza yiwo owenza i-graphite enwebekayo ibe yinto ehlukile emndenini wezinto ze-graphite.

Isiphetho

I-Graphite enwebekayo iyinhlanganisela yokuhlanganiswa kwe-graphite ephathwa ngamakhemikhali ebola ngokushesha ukuze ikhiqize i-graphite enwebekayo enesakhiwo esifana ne-worm esinezimbobo, futhi lokhu kuguqulwa kuyinika izakhiwo ezivelele ekubambezelekeni komlilo, ekuvaleni, ekushiseni ukushisa, kanye nasezinhlelweni zobunjiniyela bezimboni.

Ikhono layo lokukhula kakhulu ngaphansi kokushisa lenza libe yinto ebalulekile esebenzayo ezinhlelweni zokuphepha, imishini yokushisa okuphezulu, kanye nokukhiqizwa okuhlanganisiwe okuthuthukisiwe, lapho izinhlobo ze-graphite zendabuko zingenakunikeza izinga elifanayo lokusebenza.

Njengoba izindinganiso zokuphepha kwezimboni kanye nezidingo zokusebenza kwezinto ziqhubeka nokukhula, i-graphite enwebekayo izohlala iyinto ebalulekile yekhabhoni esebenzayo ezimbonini zokukhiqiza zomhlaba wonke.
