Yiziphi izici zegraphite enwebekayo ngemuva kokushisisa ibe yigraphite enwebekayo?

Izici zokunwetshwa zeishidi le-graphite elinwebekayozihlukile kwamanye ama-ejenti wokunweba. Lapho ishiselwa ezingeni elithile lokushisa, i-graphite enwebekayo iqala ukwanda ngenxa yokubola kwezinhlanganisela ezimuncwe ku-interlayer lattice, okubizwa ngokuthi izinga lokushisa lokuqala lokunwetshwa. Inwebeka ngokuphelele ku-1000 ℃ futhi ifinyelela umthamo omkhulu. Ivolumu yokunweba ingafinyelela izikhathi ezingaphezu kuka-200 yenani lokuqala. I-graphite eyandisiwe ibizwa ngokuthi i-graphite eyandisiwe noma i-graphite worm, eguqukayo ukusuka ekumisekeni kwe-flake yasekuqaleni ukuya ekumiseni kwesikelemu ngokuminyana okuphansi, kwakha ungqimba oluhle kakhulu lokuvikela ukushisa. I-graphite eyandisiwe ayiwona nje umthombo wekhabhoni ohlelweni lokwandisa, kodwa futhi ungqimba oluvikelayo. Ingakwazi ngempumelelovikela ukushisa. Emlilweni, inezici zezinga eliphansi lokukhishwa kokushisa, ukulahlekelwa okuncane kwesisindo kanye negesi elincane le-flue.

Yiziphi izici zegraphite enwebekayo ngemuva kokushisisa ibe yigraphite enwebekayo?

Izici ze-graphite enwetshiwe

① Ukumelana nokucindezela okuqinile,ukuguquguquka, ipulasitiki kanye nokuzigcoba;

② Ukumelana okuqinile nokushisa okuphezulu, okuphansi,ukugqwalakanye nemisebe;

③ Izici zokuzamazama komhlaba eziqine ngokwedlulele;

④ Iqine ngokwedluleleconductivity;

⑤Izakhiwo eziqinile zokulwa nokuguga kanye ne-anti-distortion.

⑥ Ingakwazi ukumelana nokuncibilika nokungena kwezinsimbi ezihlukahlukene;

⑦ Ayinabuthi, ayinawo amakhemikhali e-carcinogen futhi ayilimazi imvelo.

Izikhombisi-ndlela eziningana zokuthuthukiswa kwe-graphite enwetshiwe zimi kanje:

1. I-graphite enwetshiwe ngezinjongo ezikhethekile

Ukuhlola kubonisa ukuthi izikelemu ze-graphite zinomsebenzi wokumunca amaza kagesi. I-graphite eyandisiwe kufanele ihlangabezane nezidingo ezilandelayo: (1) izinga lokushisa eliphansi lokuqala lokunwetshwa kanye nevolumu enkulu yokwandisa; (2) Izakhiwo zamakhemikhali zizinzile, zigcinwa iminyaka emi-5, futhi isilinganiso sokunwetshwa empeleni asiboli; (3) Ingaphezulu legraphite elinwetshiwe alinahlangothi futhi alinakho ukugqwala kwekesi le-cartridge.

2. I-graphite enwetshiwe eyimbudumbudu

I-graphite enwetshiwe yezinhlayiyana ezincane ibhekisela kuma-graphite anwebekayo angama-300 anomthamo wokunwebeka ongu-100ml/g. Lo mkhiqizo usetshenziselwa ikakhulukazi i-flame retardantezinengilazi, edingeka kakhulu.

3. I-graphite enwetshiwe enezinga eliphezulu lokushisa lokuqala lokunwetshwa

Izinga lokushisa lokuqala lokunwetshwa kwegraphite enwetshiwe enezinga lokushisa eliphakeme lokuqala lokunwetshwa ngu-290-300 ℃, futhi ivolumu yokunweba ingu-≥ 230ml / g. Lolu hlobo lwe-graphite enwetshiwe lusetshenziselwa ikakhulukazi ukunqanda ilangabi lamapulasitiki obunjiniyela kanye nerabha.

4. I-graphite eguquliwe ebusweni

Uma i-graphite enwetshiwe isetshenziswa njengezinto ezivimbela ilangabi, ifaka ukuhambisana phakathi kwegraphite nezinye izakhi. Ngenxa ye-mineralization ephezulu ye-graphite surface, ayiyona i-lipophilic noma i-hydrophilic. Ngakho-ke, ubuso be-graphite kufanele buguqulwe ukuze kuxazululwe inkinga yokuhambisana phakathi kwe-graphite nezinye izingxenye. Kuye kwahlongozwa ukuba kwenziwe i-graphite surface ibe mhlophe, okungukuthi, ukumboza indawo ye-graphite ngefilimu emhlophe eqinile, okuyinkinga enzima ukuyixazulula. Kubandakanya i-membrane chemistry noma i-surface chemistry. Ilabhorethri ingakwazi ukwenza kanjalo, futhi kunobunzima ekuthuthukisweni kwezimboni. Lolu hlobo lwe-graphite enwebekayo emhlophe lusetshenziswa kakhulu njenge-flame retardant coating.

5. Izinga lokushisa eliphansi lokuqala lokunwetshwa kanye nezinga lokushisa eliphansi elinwetshiwe legraphite

Lolu hlobo lwe-graphite olwandisiwe luqala ukwanda ngo-80-150 ℃, futhi umthamo wokunweba ufinyelela ku-250ml / g ku-600 ℃. Ubunzima ekulungiseleleni umhlangano we-graphite onwebekayo kulo mbandela yilezi: (1) ukukhetha i-ejenti yokuxhumana efanele; (2) Ukulawula nokuphatha izimo zokomisa; (3) Ukunqunywa komswakama; (4) Isixazululo sezinkinga zokuvikelwa kwemvelo.
