Yiziphi izici ze-graphite enwebekayo ngemva kokufudumeza ibe yi-graphite enwebekayo?

Izici zokwandisa zeishidi le-graphite elinwebekayozihlukile kwezinye izinto zokwandisa. Uma zishiswa zifike ezingeni lokushisa elithile, i-graphite enwebekayo iqala ukwanda ngenxa yokubola kwamakhemikhali amuncwa yi-lattice ye-interlayer, ebizwa ngokuthi izinga lokushisa lokuqala lokukhulisa. Iyanda ngokuphelele ku-1000 ℃ futhi ifinyelele ivolumu ephezulu. Ivolumu yokukhulisa ingafinyelela izikhathi ezingaphezu kuka-200 zenani lokuqala. I-graphite enwebekayo ibizwa ngokuthi i-graphite enwebekayo noma i-graphite worm, eshintsha kusuka esimweni sokuqala se-flake ibe yisimo se-worm enobukhulu obuphansi, yakha ungqimba oluhle kakhulu lokuvikela ukushisa. I-graphite enwebekayo ayiyona nje umthombo wekhabhoni ohlelweni lokukhulisa, kodwa futhi iyingqimba yokuvikela. Ingaphumelelavimbela ukushisa. Uma ivutha, inezici zokukhishwa kokushisa okuphansi, ukulahleka okuncane kwesisindo kanye negesi encane yoketshezi.

Yiziphi izici ze-graphite enwebekayo ngemva kokufudumeza ibe yi-graphite enwebekayo?

Izici ze-graphite enwetshiwe

① Ukumelana nokucindezela okunamandla,ukuguquguquka, i-plasticity kanye nokuzigcoba ngokwakho;

② Ukumelana okunamandla nokushisa okuphezulu, okuphansi,ukugqwalakanye nemisebe;

③ Izici zokuzamazama komhlaba eziqine kakhulu;

④ Inamandla kakhuluukuhanjiswa komoya;

⑤Izakhiwo ezinamandla zokulwa nokuguga kanye nokuphambuka.

⑥ Ingamelana nokuncibilika nokungena kwezinsimbi ezahlukahlukene;

⑦ Ayinabo ubuthi, ayinazo izinto ezibangela umdlavuza futhi ayilimazi imvelo.

Iziqondiso eziningana zokuthuthukiswa kwe-graphite enwetshiwe yilezi ezilandelayo:

1. I-graphite enwetshiwe ngezinjongo ezikhethekile

Ukuhlolwa kubonisa ukuthi izimpethu ze-graphite zinomsebenzi wokumunca amaza kagesi. I-graphite enwetshiwe kumele ihlangabezane nezidingo ezilandelayo: (1) izinga lokushisa eliphansi lokuqala lokunwetshwa kanye nomthamo omkhulu wokunwetshwa; (2) Izakhiwo zamakhemikhali zizinzile, zigcinwa iminyaka emi-5, futhi isilinganiso sokunwetshwa empeleni asiboli; (3) Ubuso be-graphite enwetshiwe abuthathi hlangothi futhi abunawo ukugqwala ebhokisini le-cartridge.

2. I-graphite enwetshiwe enobumba

I-graphite encane enwetshiwe ikakhulukazi ibhekisela ku-graphite enwebekayo enama-mesh angu-300 enomthamo wokwandiswa ongu-100ml / g. Lo mkhiqizo usetshenziselwa kakhulu ukuvimbela ilangabiizembozo, okuyinto edingeka kakhulu.

3. I-graphite enwetshiwe enokushisa okuphezulu kokuqala kokunwetshwa

Izinga lokushisa lokuqala lokunwetshwa kwe-graphite enwetshiwe enokushisa okuphezulu kokuqala kokunwetshwa lingu-290-300 ℃, kanti ivolumu yokunwetshwa ingu-≥ 230ml / g. Lolu hlobo lwe-graphite enwetshiwe lusetshenziswa kakhulu ekuvimbeleni ilangabi kwamapulasitiki obunjiniyela kanye nerabha.

4. I-graphite eguquliwe ebusweni

Uma i-graphite enwetshiwe isetshenziswa njengento evimbela ilangabi, ihilela ukuhambisana phakathi kwe-graphite nezinye izingxenye. Ngenxa yokwakheka okuphezulu kwamaminerali ebusweni be-graphite, ayinciphi futhi ayinciphili emanzini. Ngakho-ke, ubuso be-graphite kumele buguqulwe ukuze kuxazululwe inkinga yokuhambisana phakathi kwe-graphite nezinye izingxenye. Kuye kwaphakanyiswa ukuthi kucwebe ubuso be-graphite, okungukuthi, ukumboza ubuso be-graphite ngefilimu emhlophe eqinile, okuyinkinga enzima ukuyixazulula. Ihilela i-membrane chemistry noma i-surface chemistry. Ilabhorethri ingakwazi ukwenza kanjalo, futhi kunezinkinga ekwakhiweni kwezimboni. Lolu hlobo lwe-graphite emhlophe enwebekayo lusetshenziswa kakhulu njengengubo evimbela ilangabi.

5. Izinga lokushisa eliphansi lokuqala lokunwetshwa kanye ne-graphite enwetshiwe ephansi lokushisa

Lolu hlobo lwe-graphite enwetshiwe luqala ukwanda ku-80-150 ℃, futhi ivolumu yokwanda ifinyelela ku-250ml / g ku-600 ℃. Ubunzima ekulungiseleleni i-graphite enwetshiwe ehlangabezana nalesi simo yilezi: (1) ukukhetha i-ejenti yokuhlanganisa efanele; (2) Ukulawula nokulawula izimo zokomisa; (3) Ukunqunywa komswakama; (4) Isixazululo sezinkinga zokuvikela imvelo.
