Iielectrode zegraphite zisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zabo ezikhethekileyo kunye nokuguquguquka.Phakathi kwezixhobo ezahlukeneyo ezikhoyoukwenziwa kwee-electrode, i-graphite iye yavela njengokhetho olukhethiweyo, ngokuyinhloko ngenxa yokudibanisa okukhethekileyo kwe-conductivity ebalaseleyo kunye nokumelana okuphezulu nokushisa kunye nokubola kweekhemikhali.
Kutheni igraphite isetyenziswa njenge electrode
Mna:Ukuqhuba okuBalaseleyo:
Esinye sezizathu eziphambili zokusebenzisa igraphite njengee-electrode zigqwesileyoconductivity yombane.I-graphite ibonisa iqondo eliphezulu lokuhamba kwe-electron, evumela ukuba ihambise ngokufanelekileyo umbane wangoku.Le propati iqinisekisa ukuhanjiswa kwamandla ngokufanelekileyo kwiimpendulo ze-electrochemical.
II:Ukumelana nobushushu:
Igraphite inamandla akhethekileyo okumelana namaqondo obushushu aphezulu, iyenza ibe yeyona nto ifanelekileyo yokusetyenziswa njengee-electrode.I-interlayer bonding kwigraphite ibuthathaka, ivumela iileya ukuba zihlukane ngokulula.Esi sakhiwo sikhethekileyo senza igraphite imelane kakhulu nomothuko we-thermal kwaye iyenza ikwazi ukugcina ingqibelelo yesakhiwo sayo naphantsi kweemeko zobushushu obugqithisileyo.
III: Uzinzo kwiMichiza:
Iielectrode zegraphite zikwabonisa ukuxhathisa okumangalisayo kukonakala kweekhemikhali.Abachatshazelwa lula ziimeko zeekhemikhali ezinobunzima ezikhoyo kwiinkqubo zoshishino, ezifana nokucocwa kwesinyithi kunye ne-electrodeposition.Oku kuzinza kweekhemikhali kuqinisekisa ubomi obude be-electrodes kwaye kunciphisa imfuno yokutshintshwa rhoqo.
IV:Ukwandiswa kweThermal ephantsi:
Enye inzuzo yee-electrode zegraphite yi-coefficient yazo ephantsi yokwandisa i-thermal.Njengoko zifudumeza ngexesha lokusebenza, i-electrode yegraphite yandisa kancinci, inciphisa umngcipheko wokuqhekeka okubangelwa uxinzelelo okanye ukwaphuka.Le propati igalelo ekuhlala kuyo yonke into kunye nokuthembeka kwee-electrodes, ukuqinisekisa ukuba zihlala ixesha elide.
V:Iinkqubo eziNxibelelanayo:
Ngaphandle koshishino lwentsimbi,i-electrode yegraphitefumana izicelo ezahlukeneyo kumacandelo ahlukeneyo.Zisetyenziswa kakhulu ekuvelisweni kweentsimbi ezingezizo i-ferrous, ezifana ne-aluminiyam, ubhedu, i-nickel, kunye ne-titanium.Ukongeza, ii-electrode zegraphite zidlala indima ebalulekileyo ekwenziweni kweekhemikhali, kubandakanya i-chlorine, i-fluorine, kunye ne-sodium hydroxide, ngeenkqubo ze-electrolysis.
VI.Uzinzo lokusiNgqongileyo:
Iielectrode zegraphite ziye zafumana ingqwalasela eyongeziweyo kwiminyaka yakutshanje ngenxa yokuzinza kwazo kwendalo.Xa kuthelekiswa ne-carbon electrode yendabuko, i-electrode yegraphite inokukhutshwa kwekhabhoni ephantsi ngexesha lenkqubo yokuvelisa intsimbi.Ukongeza, i-graphite ephezulu ye-thermal conductivity inegalelo ekusebenzeni kakuhle kwamandla, ukunciphisa ukusetyenziswa kwamandla ngokubanzi.
VII.Iingqwalasela zoQoqosho:
Nangona i-electrode ye-graphite ingaba neendleko eziphezulu zokuqala xa kuthelekiswa nezinye izinto, iipropati zabo eziphezulu kunye nobomi benkonzo ende bubenza ukuba bakhethe iindleko ezifanelekileyo kwixesha elide.Ukuchasana kwee-electrode zegraphite ekuqhekekeni kunye ne-oxidation kuqinisekisa ukutshintshwa okumbalwa, ukunciphisa ixesha lokuphumla kunye neendleko zokugcina.
Iimpawu zee-electrodes zegraphitezibonelela nge-conductivity egqwesileyo engenakulinganiswa nanto, ukumelana nobushushu obukhethekileyo, ukuzinza kweekhemikhali, kunye ne-coefficient yokwandisa i-thermal ephantsi, ibenza ibe lolona khetho lufanelekileyo kwizicelo ezahlukeneyo zemizi-mveliso.Ukuguquguquka kwabo, ukuzinza kwendalo, kunye neendleko zexesha elide kubenza baxatyiswe kakhulu kwimveliso yentsimbi, ukucocwa kwesinyithi esingenawo i-ferrous, kunye nokuveliswa kweekhemikhali.Njengoko itekhnoloji iqhubeka nokuguquka, ii-electrode zegraphite zinokungqina ukuphuculwa ngakumbi, ukuqinisa isikhundla sabo njengento yokuya kwizinto ezisebenzayo nezithembekileyo ze-electrode.
