Kuwonjezedwa graphite, amatchedwanso vermicular graphite, ndi crystalline pawiri kuti amagwiritsa ntchito thupi kapena mankhwala njira intercalate sanali mpweya reactants mu mwachibadwa-scaled graphite intercalated nanocarbon zipangizo ndi kuphatikiza ndi mpweya hexagonal maukonde ndege pamene kusunga Graphite wosanjikiza dongosolo. Sikuti amangosunga zabwino kwambiri zakuthupi ndi zamankhwala za graphite, monga kukana kutentha kwambiri, kukana kwa dzimbiri, kutulutsa kwa neutron, X-ray ndi gamma-ray yanthawi yayitali. Ilinso ndi zinthu zabwino kwambiri zakuthupi komanso zamankhwala, monga kugundana kocheperako, kudzipaka bwino, magetsi ndi matenthedwe, komanso anisotropy. Komanso, chifukwa cha kugwirizana pakati pa zinthu intercalated ndi graphite wosanjikiza, kukodzedwa graphite amasonyeza zinthu zatsopano kuti pristine graphite ndi intercalated zakuthupi alibe, ndi kugonjetsa brittleness ndi kukana mphamvu graphite zachilengedwe. Otsatira otsatirawa a Furuite graphite amagawana kuyambika kwa njira zopangira mafakitale ndikugwiritsa ntchito graphite yowonjezereka:
1. Njira zopangira zomwe zimagwiritsidwa ntchito kwambiri m'makampani
①Chemical oxidation
Ubwino: Chemical oxidation ndi njira yogwiritsidwa ntchito kwambiri komanso yokhazikitsidwa bwino m'makampani. Choncho, ili ndi ubwino woonekeratu, teknoloji yokhwima komanso yotsika mtengo.
Zoyipa: The intercalating agent nthawi zambiri imakhala sulfuric acid, yomwe imadya asidi wambiri. Pali kuipitsidwa kwa mpweya woipa wa Sox popanga, ndipo zotsalira zomwe zili muzinthuzo zimawononganso zida zopangira.
②Kuthiridwa kwa electrochemical
Monga makutidwe ndi okosijeni amankhwala, ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito popanga ma graphite.
Ubwino: Palibe chifukwa chowonjezera ma oxidants amphamvu, monga ma asidi amphamvu, ndipo zomwe zimachitika zimatha kuwongoleredwa mwa kusintha magawo monga apano ndi magetsi. Zida zophatikizira ndizosavuta, kuchuluka kwa kaphatikizidwe ndi kwakukulu, ma electrolyte samadetsedwa, ndipo atha kugwiritsidwanso ntchito.
Zoipa: Kukhazikika kwa mankhwala opangidwa ndi osauka kuposa njira zina, zomwe zimafuna zipangizo zamakono, ndipo pali zinthu zambiri zomwe zimakhudza ubwino wa mankhwala. Nthawi zina, kuchuluka kwa mankhwalawa kumachepetsedwa kwambiri chifukwa cha kutentha kozungulira. Kuonjezera apo, pali zochitika zam'mbali pamafunde apamwamba muzitsulo zamadzimadzi, kotero zimakhala zovuta kupeza mankhwala oyambirira.
2. Main mabizinesi kupanga ndi mphamvu kupanga
Kupanga kwazinthu zowonjezera za graphite m'dziko langa kwakula kuyambira pachiyambi mpaka opanga oposa 100, ndi kutulutsa kwapachaka kwa matani 30,000, ndipo ndende yamsika ndiyotsika. Komanso, opanga ambiri amakhala osindikizira otsika kwambiri, omwe sagwiritsidwa ntchito kawirikawiri pazisindikizo zamagalimoto ndi magetsi oyendera ndege. Komabe, ndi chitukuko cha teknoloji yapakhomo, chiwerengero cha mankhwala apamwamba chidzawonjezeka pang'onopang'ono.
3. Kufuna kwa msika ndi kuwonetseratu kwa zipangizo zosindikizira
Pakalipano, graphite yowonjezera imagwiritsidwa ntchito makamaka ngati zipangizo zosindikizira zamagalimoto, monga ma cylinder gaskets, kudya ndi kutulutsa mpweya wamagetsi, ndi zina zotero. Zida zosindikizira za graphite m'dziko langa zimagwiritsidwa ntchito makamaka ngati zosindikizira. Pakalipano, graphite yowonjezera yokhala ndi mpweya wochepa wa carbon yapangidwa, yomwe ingachepetse kwambiri mtengo wopangira graphite yowonjezera, potero m'malo mwa asibesitosi pamlingo waukulu ndikuwonjezeka kwa kufunikira. Kumbali ina, ngati pulasitiki, mphira ndi zitsulo zosindikizira zida zitha kusinthidwa pang'ono, kufunikira kwapakhomo kwapachaka kwa zida zowonjezera zosindikizira za graphite kudzakhala kwakukulu.
M'makampani amagalimoto, galimoto iliyonse ya silinda yamutu wa gasket, kutengera mpweya komanso mpweya wotulutsa mpweya umafunika pafupifupi 2 ~ 10kg ya graphite yowonjezedwa, ndipo magalimoto 10,000 aliwonse amafunikira matani 20 ~ 100 a graphite wokulitsidwa. Makampani opanga magalimoto ku China alowa m'nthawi yachitukuko chofulumira. Chifukwa chake, dziko langa lomwe likufuna pachaka pazowonjezera zosindikizira za graphite ndikadali ndi cholinga.
