Kuyini i-Rigid Graphite Felt?

Eminyakeni yamuva nje, umhlaba wezimboni ubone ukusetshenziswa okwandayo kwezinto ezithuthukisiwe ezinikeza ukuqina okuthuthukisiwe, amandla, kanye nokumelana nokushisa. Phakathi kwalokhu,i-graphite eqinilekuvele njengengxenye ebalulekile ezinhlobonhlobo zezicelo, kusukela ekushiseni okushisa okuphezulu kuya ezinqubweni zokukhiqiza ezikhethekile.

Kuyini i-Graphite Felt?

Ngaphambi kokufunda nge-graphite eqinile, kubalulekile ukuqonda kuqala ukuthi iyini i-precursor yayo. i-graphite feltI-Graphite felt uhlobo lwezinto zekhabhoni ezidalwe ngokuguqula izinhlobo ezahlukene zemicu eyandulelayo, njenge-rayon noma i-polyacrylonitrile (PAN), zibe izinto ezifakwe i-carbon ngenqubo eyaziwa ngokuthi i-pyrolysis. Umphumela uba izinto ezithambile, eziguquguqukayo, nezilula ezigcina ukumelana nokushisa okuphezulu kanye nezici zokuqhuba i-graphite.

Nakuba i-graphite felt ivame ukusetshenziswa ezimbonini ezidinga ukushisa, njengasezithandweni, ema-oven, noma emalabhorethri, ukuguquguquka kwezinto kunciphisa ukusetshenziswa kwazo ezimweni lapho kudingeka khona ukuqina. Yilapho i-graphite felt eqinile iqala khona ukusebenza.

Kuyini i-Rigid Graphite Felt?

I-graphite eqinile ibizwa nangokuthi i-graphite hard felt nayo, iyinguqulo eguquliwe ye-graphite felt, eyenziwe ngokwelashwa okwengeziwe kanye nezinqubo zokwandisa ukuqina kwayo kanye nobuqotho besakhiwo. Ngokungafani nomlingani wayo oguquguqukayo, i-rigid graphite felt igcina isimo sayo ngaphansi kokucindezeleka futhi ingamelana nezimo zokusebenza ezinzima kakhulu. Izinto ezisetshenziswayo zivame ukufuthwa noma ukucutshungulwa ngama-binding agents noma ama-resin asiza ukwandisa ukuqina kwayo, ukuqinisekisa ukuthi igcina isimo sayo esiqinile ngisho noma ivezwa emazingeni okushisa aphezulu noma emandleni emishini.

I-graphite felt eqinile iyaziwa kakhulu ngenxa yayoukumelana nokushisa okuphezulu, ukuhanjiswa okuhle kakhulu, kanye nokuqina okumangalisayo, okwenza kube yinto efanelekile ezimbonini lapho kokubili ukucindezeleka kokushisa kanye nokwemishini kuyizinto ezibalulekile.

Izakhiwo Eziyinhloko Ze-Rigid Graphite Felt

1. Ukumelana Nokushisa Okuphezulu
   Esinye sezici eziphawuleka kakhulu ze-graphite felt eqinile yikhono layo lokubekezelela amazinga okushisa aphezulu ngaphandle kokulahlekelwa ubuqotho bayo besakhiwo. Ingabekezelela amazinga okushisa afinyelela ku-3,000°F (1,600°C), kuye ngokuthi yenziwe kanjani kanye nenqubo yokukhiqiza. Lokhu kwenza kube ukukhetha okuhle kakhulu kwezicelo ezihilela izimo zokushisa ezimbi kakhulu, njengasema-oven, kuma-reactor, noma ezinhlelweni zokushisa eziphakeme.

2. Ukuqhuba Okushisayo Okuhle Kakhulu
   I-Graphite yaziwa kakhulu nge-ukuhanjiswa kokushisa okuvelele, okungenye yezizathu ezenza ukuthi i-graphite eqinile izwakale ibaluleke kakhulu ezimbonini ezidinga ukudluliselwa kokushisa okusebenzayo. Ukushisa okuphezulu kwe-graphite felt kuqinisekisa ukuthi ukushisa kusatshalaliswa ngokulinganayo, kunciphisa ama-gradient okushisa futhi kuvimbele izindawo ezishisayo ezingalimaza imishini noma izinto ezibucayi.

3. Amandla Okusebenza
   I-graphite felt eqinile yenzelwe ukumelana nokucindezeleka komshini. Ukuqina kwayo kuyivumela ukuthi igcine isimo sayo kanye nokusebenza kwayo ngisho noma ingaphansi kwamandla afana nokucindezelwa noma ukucindezeleka. Lesi sici siyenza ibaluleke kakhulu ekusetshenzisweni lapho ubuqotho bezinto bubaluleke khona, njengasekuhlungweni kwegesi noketshezi, noma njengengxenye yesakhiwo ezindaweni ezinomfutho ophezulu.

4. Ukungasebenzi Kwamakhemikhali
   I-Graphite felt imelana kakhulu namakhemikhali amaningi, okwenza ibe yindawo ekahle yokusetshenziswa ezindaweni zamakhemikhali ezinolaka. Ayigqwali noma yonakale uma ivezwa kuma-acid, ama-alkali, noma izinyibilikisi, okwandisa impilo yayo yokusebenza kanye nokusebenza kwayo ezinqubweni eziningi zezimboni.

5. Ilula
   Naphezu kokuqina kwayo, i-graphite felt isalula uma iqhathaniswa nezinye izinto ezinikeza izakhiwo ezifanayo zokushisa nezomshini. Lokhu kwenza kube lula ukuyiphatha nokuyifaka, kuyilapho kusiza ekunciphiseni isisindo semishini nezakhiwo eziyisebenzisayo.

Ukusetshenziswa kwe-Rigid Graphite Felt

Izakhiwo eziyingqayizivele ze-graphite felt eqinile zenza ukuthi iguquguquke kakhulu futhi ibe yigugu ezimbonini eziningi. Ezinye zezinhlelo zokusebenza ezibalulekile zifaka:

1. Ukufakwa Kokushisa Okuphezulu

Enye yezindlela ezivame ukusetshenziswa kakhulu ze-rigid graphite felt ku-ukuvimbela ukushisayezithando, ama-oven, kanye nama-reactor. Ikhono layo lokubekezelela amazinga okushisa aphezulu ngenkathi igcina ubuqotho besakhiwo liyenza ibe yinto efanelekile yokuvikela imishini ebalulekile ezimbonini ezifanai-metallurgy, ukukhiqizwa kwengilazi, futhiizinto zobumba.

2. Amaseli Kaphethiloli

I-graphite felt eqinile ivame ukusetshenziswa ku-ubuchwepheshe bamaseli kaphethiloli, ikakhulukazi kumaseli kaphethiloli e-membrane ye-proton-exchange (ama-PEMFC). Ukuqhuba kwayo okuphezulu kanye nokuqina kwesakhiwo ngaphansi kokushisa kuyenza ibe yingxenye ebalulekile ekugcineni ukusebenza kwamaseli ngenkathi futhi iqinisekisa ukusatshalaliswa kokushisa okuphumelelayo.

3. Izivikelo Zokushisa Nezithiyo Zokushisa

Ezimbonini zezindiza, zezimoto, nakwezinye izimboni ezisebenza kahle kakhulu, i-graphite felt eqinile isetshenziswaizivikelo zokushisafuthiizithiyo zokushisaukuvikela izingxenye ezizwelayo ekushiseni okukhulu. Kungakhathaliseki ukuthi izindiza-mkhathi eziphinde zingene emkhathini woMhlaba noma izinhlelo zokukhipha umoya ezimotweni ezisebenza kahle kakhulu, i-graphite felt eqinile isebenza njengesivikelo esithembekile esingamelani nokushisa.

4. Ama-Reactors Amakhemikhali

Ngenxa yokungasebenzi kahle kwamakhemikhali kanye nokumelana nokugqwala, i-graphite felt eqinile isetshenziswa ku-ama-reactor amakhemikhaliezisebenza ngaphansi kwezimo ezimbi kakhulu. Kuyasiza ekuvikeleni nasekuqiniseni izinqubo zokushisa okuphezulu ngenkathi kugcinwa ukusebenza kahle kokushisa okuqhubekayo.

5. Izicelo Zokuhlanza I-Vacuum

In izinhlelo zokuhlanza umoya, i-graphite felt eqinile isetshenziswa njenge-liner noma izinto zokuvikela ukushisa. Uhlobo lwayo olulula kanye nokumelana namazinga okushisa aphezulu kuyenza isebenze kahle ekugcineni ubuqotho bamakamelo okuhlanza, iqinisekise ukuphathwa kokushisa okuphumelelayo ezinhlelweni ezifanaizitofu zokuhlanza or isitoreji se-cryogenicamathangi.
