Ngawaphi amanyathelo abalulekileyo kwinkqubo yokwenziwa kwee-electrode ze-graphite?

Inkqubo yokwenziwa kwee-electrode ze-graphite yinkqubo enzima necokisekileyo equka amanyathelo amaninzi abalulekileyo, ngalinye lichaphazela kakhulu umgangatho kunye nokusebenza kwemveliso yokugqibela. Nazi amanyathelo aphambili kwinkqubo yokwenziwa kwee-electrode ze-graphite:

Ukukhethwa kwezinto eziluhlaza kunye nonyango lwangaphambi kwexesha:

• Ukukhethwa kwezinto eziluhlaza: Izinto eziluhlaza eziphambili ze-graphite electrodes ziquka i-petroleum coke, i-needle coke, kunye ne-coal tar pitch. I-petroleum coke, ephuma kwi-coking ye-petroleum residue kunye ne-asphalt, inomlotha omncinci; i-needle coke, ebonakala ngokuba ne-fibrous texture kunye ne-coefficient ephantsi yokwanda kobushushu, ibalulekile ekwenzeni ii-electrode ze-graphite ezinamandla aphezulu okanye aphezulu kakhulu; i-coal tar pitch isebenza njengesihlanganisi.
• Unyango lwangaphambi konyango: Izinto ezikrwada ziyafakwa kwi-calcination ukuze kususwe umswakama kunye nezinto eziguquguqukayo, nto leyo ephucula iipropati zazo ze-physicochemical. Ubushushu be-calcination bulawulwa ngokubanzi phakathi kwe-1250-1350°C ukuqinisekisa ukuba izinto ezikrwada ziyahlangabezana nemigangatho yomgangatho ophezulu.

Ukutyumza, Ukusila, kunye nokuHlola:
Izinto ezikrwada ezifakwe i-calcium ziyatyunyuzwa, zicolwe, zize zihlolwe ukuze kufunyanwe amasuntswana ethambo kunye nomgubo onobukhulu obufunekayo besuntswana. Eli nyathelo libalulekile kwiinkqubo ezilandelayo zokuxuba nokuxuba, ukuqinisekisa ukufana kunye nokuhambelana kwezinto ezikrwada.

Ukudibanisa nokuxuba:

• Ukuxuba: Ngokusekelwe kwiimfuno zemveliso, izinto ezisetyenzisiweyo ezikhethiweyo zixutywa ngokwemilinganiselo ethile ukuze kufezekiswe ukusebenza okufunekayo. Ukulinganisa ngokuchanekileyo kunye nolawulo ngexesha lokuxuba kubalulekile ukuqinisekisa umgangatho ohambelanayo kwimveliso yokugqibela.
• Ukuxuba: Izinto eziluhlaza ezixutyiweyo zixutywa kakuhle kwaye zixovwe ukuze zenze umxube ofanayo. Ubushushu kunye nexesha zilawulwa ngexesha lokuxuba ukuqinisekisa ukuxubana okufanelekileyo kunye neplastiki enqwenelekayo yezinto eziluhlaza.

Ukubumba:
Izinto ezixovweyo zicinezelwa ukuze zenze imo yokuqala ye-graphite electrode. Ulawulo oluchanekileyo loxinzelelo kunye nobushushu ngexesha lokubumba luyimfuneko ukuqinisekisa ukuchaneka kobume kunye nobukhulu bemveliso. Iindlela zokubumba ziquka ukucinezela ngoxinzelelo, ukukhupha, kunye nokubumba ngokungcangcazela, okukhethwa ngokusekelwe kuhlobo lwemveliso kunye neenkcukacha.

Ukubhaka:
I-electrode yegrafiti ebunjiweyo ifumana unyango lobushushu obuphezulu ukuze iqinise isakhiwo sayo. Ngexesha lokubhaka, i-coal tar pitch emzimbeni oluhlaza iyagoba, ikhuphe i-volatiles ngelixa ifumana ukuncipha komthamo kunye nokulahleka kobunzima. I-electrode ebhakiweyo ibonisa iipropati ze-physicochemical eziphuculweyo kakhulu, ezinje ngokuncipha kobuninzi, ukuncipha kokumelana kombane, kunye namandla oomatshini aphuculweyo.

Ukufunxa (Ukhetho):
Kwii-electrode ezineemfuno eziphezulu zoxinano olukhulu, unyango lokufunxa luyimfuneko. Ukufunxa lujolise ekunciphiseni ukuxinana kwemveliso, ukonyusa uxinano lwayo olukhulu kunye namandla oomatshini, kunye nokuphucula ukuhanjiswa kwayo kombane kunye nobushushu. Iiparameter ezinje ngobushushu bokufudumeza kwangaphambili, ixesha lokufunxa, ubushushu bokufaka i-asphalt, kunye noxinzelelo zilawulwa ngexesha lokufunxa.

Ukwenziwa kweGraphitization:
I-electrode iphathwa kumaqondo obushushu aphezulu nangakumbi ukuguqula isakhiwo sezinto zekhabhoni sibe yisakhiwo sekristale yegrafiti, nto leyo ephucula ukuhanjiswa kwayo kombane kunye nokumelana nobushushu. Ubushushu kunye nexesha zilawulwa ngexesha le-graphitization ukuqinisekisa ukuba i-electrode ifikelela kwinqanaba elifunekayo le-graphitization. I-electrode yegrafiti ibonisa ukuncipha okukhulu kokumelana kombane kunye nokuphuculwa kakhulu kokuhanjiswa.

Umatshini:
I-electrode enemifanekiso idlula kwi-machining, kuquka ukubhoboza, ukujika, ukugqiba ubuso obupheleleyo, ukugaywa kwemisonto, kunye namanyathelo afana nokusika, ukucanda ubuso obupheleleyo, ukujika okucothayo, kunye nokubhoboza izihlanganisi. Ulawulo oluqinileyo lokuchaneka komatshini kunye nomgangatho womphezulu luyimfuneko ngexesha lomatshini ukuqinisekisa ukuchaneka kunye nokusebenza komlinganiselo we-electrode.

Ukuhlolwa kunye nokuPakisha:
I-electrode egqityiweyo ihlolwa ngokupheleleyo, kuquka iiparameter ezifana nokuchaneka, ubunzima, ubude, ububanzi, uxinano olukhulu, ukumelana nombane, kunye nokuchaneka kokulingana ngaphambi kokuhlanganiswa. Emva kokudlula kuhlolo, i-electrode ipakishwa ukuze ithuthwe kwaye igcinwe.
