Kupanga m'badwo watsopano wa zida zapamwamba za graphite

High chiyero graphiteamatanthauza graphite yokhala ndi mpweya woposa 99.99%. Kuyera koyera kwa graphite kuli ndi zabwino monga kukana kutentha kwambiri, kukana kwa dzimbiri, kukana kugwedezeka kwamafuta, kuchuluka kwamafuta ochepa, kudzipaka mafuta, kukana kutsika, komanso kukonza makina osavuta. Kuchita kafukufuku wokhudza kupanga graphite yoyera kwambiri komanso kuwongolera zinthu zabwino ndizofunikira kwambiri pakukula kwamakampani aku China oyeretsa kwambiri a graphite.

Pofuna kulimbikitsa chitukuko cha mafakitale a graphite ku China, kampani yathu yayika ndalama zambiri za anthu ogwira ntchito komanso zothandizira pa kafukufuku ndi chitukuko cha graphite yapamwamba kwambiri, zomwe zimathandiza kwambiri kuti graphite ikhale yoyera kwambiri. Tsopano ndikuuzeni za kafukufuku ndi chitukuko cha kampani yathu:

1. General process flow popanga high-purity graphite:

Njira yayikulu yopangira graphite yoyera kwambiri ikuwonetsedwa mu Chithunzi 1. N'zoonekeratu kuti kupanga graphite yoyera kwambiri ndi yosiyana ndi ma electrode a graphite. Kuyera koyera kwa graphite kumafunikira zida zopangira za isotropic, zomwe zimafunika kusinthidwa kukhala ufa wonyezimira. Ukadaulo wopondereza wa Isostatic uyenera kugwiritsidwa ntchito, ndipo kuzungulira kwawotcha ndikotalika. Kuti mukwaniritse kachulukidwe womwe mukufuna, kuzungulira kowotcha kangapo kumafunika, ndipo kuzungulira kwa graphitization ndikutali kwambiri kuposa graphite wamba.

1.1 Zopangira

Zida zopangira graphite yoyera kwambiri imaphatikizapo ma aggregates, binders, ndi ma inregnating agents. Zophatikiza nthawi zambiri zimapangidwa ndi singano yopangidwa ndi petroleum coke ndi asphalt coke. Izi ndichifukwa choti mafuta a petroleum coke ali ndi mawonekedwe monga phulusa lochepa (nthawi zambiri zosakwana 1%), graphitization yosavuta pa kutentha kwambiri, kuwongolera bwino komanso kusinthasintha kwamafuta, komanso kukulitsa kocheperako; The graphite anapezedwa ntchito phula coke pa kutentha graphitization chomwecho ali ndi apamwamba mphamvu resistivity magetsi koma apamwamba mawotchi mphamvu. Choncho, popanga zinthu za graphitized, kuwonjezera pa petroleum coke, gawo la asphalt coke limagwiritsidwanso ntchito kupititsa patsogolo mphamvu zamakina za mankhwala. Omangira nthawi zambiri amagwiritsa ntchito phula la malasha,chomwe chimachokera ku distillation ya phula la malasha. Ndi yakuda yolimba kutentha kutentha ndipo ilibe malo osungunuka okhazikika.

1.2 Kuwerengera / Kuyeretsa

Mawerengedwe amatanthauza kutenthetsa kutentha kwambiri kwa zinthu zosiyanasiyana zolimba za mpweya pansi pamikhalidwe ya mpweya. Magulu osankhidwa amakhala ndi chinyezi, zonyansa, kapena zinthu zosasunthika m'kati mwake chifukwa cha kusiyana kwa kutentha kwa coking kapena zaka zakubadwa kwa malasha. Zinthu izi ziyenera kuthetsedwa pasadakhale, apo ayi zingakhudze khalidwe la mankhwala ndi ntchito. Chifukwa chake, zigawo zosankhidwa ziyenera kuchepetsedwa kapena kuyeretsedwa.

1.3 Kupera

Zida zolimba zomwe zimagwiritsidwa ntchito popanga ma graphite, ngakhale kukula kwa chipika kumachepetsedwa pambuyo pa calcination kapena kuyeretsedwa, kumakhalabe ndi tinthu tating'onoting'ono tokhala ndi kusinthasintha kwakukulu komanso kapangidwe kake. Choncho, m`pofunika kuphwanya akaphatikiza tinthu kukula kukwaniritsa pophika zofunika.

1.4 Kusakaniza ndi kukanda

Ufa wapansi uyenera kusakanizidwa ndi chomangira phula la malasha molingana musanawuike mu makina otentha okandira kuti awonetsetse kuti zinthuzo zimagawidwa mofanana.

1.5 Kupanga

Njira zazikuluzikulu zikuphatikiza kuumba kwa extrusion, kuumba, kugwedeza kugwedezeka, ndi kuponderezana kwa isostatic

1.6 Kuphika

Zopangira kaboni zomwe zimapangidwa zimayenera kuotcha, zomwe zimaphatikizapo kuyika kaboni mu binder coke kudzera mu kutentha (pafupifupi 1000 ℃) pansi pamikhalidwe yakutali.

1.7 Kuchotsa mimba

Cholinga cha impregnation ndi kudzaza pores ang'onoang'ono anapanga mkati mankhwala pa Kuwotcha ndondomeko ndi phula wosungunuka ndi wothandizila impregnating, komanso pores alipo poyera mu akaphatikiza coke particles, kusintha voliyumu kachulukidwe, madutsidwe, mawotchi mphamvu, ndi kukana dzimbiri mankhwala a mankhwala.

1.8 Kujambula zithunzi

Graphitization imatanthawuza njira yochizira kutentha kwambiri yomwe imasintha thermodynamically yosakhazikika yopanda graphite mpweya kukhala mpweya wa graphite kudzera pakuyatsa matenthedwe.

Takulandirani kudzayendera ndi kuyendera fakitale yathu, makamaka chinkhoswe graphite zisamere pachakudya, mkulu-chiyero graphite, crucibles graphite, nano graphite ufa, isostatic kukanikiza graphite, maelekitirodi graphite, ndodo graphite, ndi zina zotero.
