Njengoko sonke sisazi, igraphite ineempawu ezikumgangatho ophezulu ukuba ezinye izinto zetsimbi azikwazi ukuthatha indawo.Njengezinto ezikhethiweyo, izinto ze-graphite electrode zihlala zineempawu ezininzi ezididayo ekukhethweni kwangempela kwezinto.Kukho iziseko ezininzi zokukhetha izixhobo ze-electrode yegraphite, kodwa kukho iindlela ezine eziphambili:
Kwimathiriyeli enomlinganiselo ofanayo wobungakanani bamasuntswana, amandla kunye nokuqina kwemathiriyeli ene-resistivity ephantsi nayo ingaphantsi kancinane kunezo zinokumelana okuphezulu.Oko kukuthi, isantya sokukhutshwa kunye nokulahlekelwa kuya kuhluka.Ke ngoko, i-intrinsic resistivity ye-graphite electrode material ibaluleke kakhulu kwisicelo esisebenzayo.Ukukhethwa kwezinto ze-electrode kuhambelana ngokuthe ngqo nomphumo wokukhutshwa.Ubukhulu becala, ukukhethwa kwezinto eziphathekayo kumisela iimeko zokugqibela zesantya sokukhutshwa, ukuchaneka komatshini kunye nobunzima bomhlaba.
Kwishishini elikhethekileyo legraphite, umgangatho wokuvavanya ubulukhuni ngokubanzi yindlela yokuvavanya ubulukhuni be-Shore, umgaqo wayo wokuvavanya wahlukile kulowo wesinyithi.Nangona ekuqondeni kwethu igraphite, ngokuqhelekileyo ithathwa njengento ethambileyo.Kodwa idatha yovavanyo lwangempela kunye nokusetyenziswa kubonisa ukuba ubulukhuni begraphite buphezulu kunobo bezinto zetsimbi.Ngenxa yokwakheka kwegraphite, inomsebenzi ogqwesileyo wokusika kwinkqubo yokusika.Amandla okusika kuphela malunga ne-1/3 yezinto zobhedu, kwaye umgangatho owenziwe ngomatshini kulula ukuwuphatha.
Nangona kunjalo, ngenxa yobunzima bayo obuphezulu, isixhobo sokugqoka siya kuba sikhulu kancinane kuneso sezixhobo zokusika isinyithi ekusikeni.Ngexesha elifanayo, izinto ezinobunzima obuphezulu zinolawulo oluhle kakhulu lokulahleka kokukhupha.Ke ngoko, ubunzima be-Shore ye-graphite electrode material nayo yenye yeendlela zokukhetha ze-graphite electrode material.
Emva koko kukho amandla okuguquguquka kwezixhobo ze-electrode zegraphite.Amandla e-flexural yezinto ze-graphite electrode yimbonakaliso ngokuthe ngqo yamandla ezinto eziphathekayo, ebonisa ukuxinana kwesakhiwo sangaphakathi sezinto eziphathekayo.Isixhobo esinamandla aphezulu sinokunganyangeki kakuhle kokunxiba.Kwi-electrode echanekileyo ephezulu, izinto eziphathekayo ezinamandla angcono kufuneka zikhethwe ngokusemandleni.
Ekugqibeleni, i-avareji ye-particle diameter ye-graphite electrode materials, i-avareji ye-particle diameter ye-graphite electrode materials ichaphazela ngokuthe ngqo imeko yokukhutshwa kwezinto.Umncinci umlinganiselo we-particle size, i-uniform efanayo yokukhutshwa, ukuzinza ngakumbi imeko yokukhutshwa kunye nomgangatho ophezulu womgangatho.Ubukhulu besayizi ye-particle, ngokukhawuleza isantya sokukhupha kunye nencinci ilahleko ye-roughing.Isizathu esona sizathu kukuba amandla okukhutshwa ahluka ngokunyuka kwangoku ngexesha lokukhutshwa.Nangona kunjalo, ukugqitywa komphezulu emva kokukhutshwa kuyahluka ngokutshintsha kwamaqhekeza.
I-electrode yegraphite ingaba yinto yokuqala yokukhetha izinto eziphathekayo kwishishini.Kungenxa yokuba i-electrode yegraphite ineenzuzo ezingenakunqwenelekayo ukuba eyona ndlela yokukhetha echanekileyo yee-electrode zegraphite kunye nokukhetha izibini ezifanelekileyo zeeelectrode zegraphite zingundoqo.
