Ukuhlanzeka kwempuphu ye-graphite emikhiqizweni ye-graphite electrode kuyipharamitha ebalulekile yempuphu ye-graphite futhi kuyinto okumele bobabili abasebenzisi abathenga i-graphite powder kanye ne-graphite powder bayiqonde. I-Graphite ngokwayo iyiminerali yemvelo ye-crystalline ye-carbon, futhi okuqukethwe kwekhabhoni okuhleliwe kuyisibonakaliso esiyinhloko sokuhlanzeka kwempuphu ye-graphite. Ngaphambi kokushiya ifektri noma ukuqhubeka nokucutshungulwa, i-graphite powder kumele ihlolwe amapharamitha ahlukahlukene, phakathi kwawo ukuhlolwa kokuhlanzeka kwempuphu ye-graphite kubalulekile.
Ukulinganisa ubumsulwa bempuphu ye-graphite ukuthola isilinganiso sokuqukethwe kwekhabhoni okuhleliwe kumpuphu ye-graphite. Ngenxa yokuthi i-graphite inokuqina okuhle kwamakhemikhali ekushiseni kwegumbi, akulula ukunquma ngqo okuqukethwe kwayo kwekhabhoni. Okuqukethwe kwekhabhoni ngokuvamile kubalwa ngenani lokushisa eliphezulu lezinto ezizohlolwa. Okusho ukuthi, okuqukethwe kwekhabhoni kubalwa ngokusekelwe enanini lezinombolo le-graphite elifakwa ku-carbon dioxide futhi liguqulwe emazingeni okushisa aphezulu. Indlela yokubala ubumsulwa bempuphu ye-graphite ukuthi i-carbon ehleliwe (%)=100%- umlotha (%)- into eguquguqukayo (%).
Imikhiqizo yamakhemikhali yansuku zonke ye-Graphene
Indlela ethile yokuhlola ubumsulwa bempuphu ye-graphite yilena elandelayo: Kala ngokunembile amasampula amabili empuphu ye-graphite engu-1-gram usebenzisa ibhalansi yokuhlaziya kagesi, bese uwabeka ngokulandelana ku-crucible ye-porcelain enezivalo ezimbili kanye nesikebhe se-graphite esinesisindo esaziwayo. Womise kuhhavini owomisa ongu-105℃ aze afinyelele isisindo esidingekayo, bese uqopha isisindo esingu-G1 no-G2 sempuphu ye-graphite ngokulandelana. Beka i-crucible ye-porcelain enezivalo ezimbili equkethe i-graphite powder esithandweni sokushisa okuphezulu bese uyigcina ekushiseni okungaguquki okungu-950℃ imizuzu engu-7 ngewashi lokumisa. Bese uyikhipha bese uyipholisa ekushiseni kwegumbi ku-desiccator. Kala impuphu ye-graphite njenge-G3. Thatha isikebhe se-graphite esinempuphu ye-graphite bese uyigcina ekushiseni okungaguquki okungu-950℃ imizuzu engu-90 esithandweni sokushisa okuphezulu. Bese ukhipha impuphu ye-graphite bese uyipholisa ekushiseni kwegumbi. Kuleli qophelo, isisindo sezinto siyisisindo somlotha we-G4. Okokuqala, bala i-volatile matter ye-graphite powder V (%)= (G1-G3)/ G1× 100%. Ngakho-ke, ifomula yokubala yobumsulwa be-graphite powder C(%)=[(G2-V- G4)/ G2]× 100% iyatholakala. Ubumsulwa be-graphite powder buyipharamitha ebaluleke kakhulu, ikakhulukazi lapho kuhlolwa ubumsulwa be-graphite powder ehlanzekile kakhulu. Kuphela lapho ubumsulwa be-graphite powder buhlangabezana nezidingo zobumsulwa be-graphite powder ehlanzekile kakhulu lapho ingabhekwa njengomkhiqizo ofanelekayo. Imboni ye-mold graphite ishintshe kancane kancane isuka kumodeli yendabuko yaya esiqondisweni esihlukahlukene kakhulu ngentuthuko yayo. Akusekho okungavamile ngamabhizinisi ukuhlanganisa amandla futhi awele imingcele ukuze asinde futhi akhule. Esimweni sokufunwa kwesikhathi esizayo, ukusetshenziswa kuzoba nokuphishekela imikhiqizo ngokwezifiso nangobungcweti.
I-electrode ye-graphite
Ngakho-ke, imboni yesikhunta se-graphite ishintsha ngenkuthalo ukuze ilandele umkhuba we-The Times futhi ithuthukise futhi ithuthukise okuqukethwe komkhiqizo. Ukuthuthukiswa kwebhizinisi kudinga ukuchwephesha ngempela. Umsabalalisi othile uthe, kulesi simo samanje, bambalwa kakhulu amabhizinisi angenza umsebenzi omuhle kakhulu ekuthuthukisweni kwezimboni ezahlukene. Njengamathayili ahlanganisa isikhunta se-graphite, isikhunta se-graphite ahlanganisa isikhunta, amakhabethe ahlanganisa isikhunta se-graphite, njll. Kuyo yonke insimu, kunemingcele yayo kanye nezici zayo, ezingenakufezwa kalula yibhizinisi elilodwa. Ukuqongelela nokuthuthukiswa kwamakhono, ubuchwepheshe kanye neziteshi konke kudinga inqubo.
Umbukiso wama-20 wekhishi negumbi lokugeza usuqalile. Abantu abangaphakathi embonini bagxile kakhulu emkhakheni wezinhlobo ze-graphite lapho bexoxa ngombukiso wekhishi negumbi lokugeza. Kodwa-ke, ikhishi negumbi lokugeza azihlukaniseki. Ngesikhathi sokuthuthukiswa kombukiso eminyakeni embalwa edlule, ikakhulukazi ngokuvulwa ngokuphelele kweHall N, amabhizinisi ekhabhinethi, amabhizinisi ezinto zasekhishini, amabhizinisi ophahla kanye nabanye abakhiqizi bonke bathuthele, futhi amabhizinisi ahlukahlukene asekelayo nawo angene ngokulandelana, okwenza imisebenzi kanye nezinto ezivelele zombukiso zibe zicebile futhi ziphelele, futhi izinzuzo zingaba zinkulu!
Kodwa-ke, ukuhlanganiswa kwezimboni kubonakala kungenakugwenywa. Isizathu sokuthi i-graphite molds, amakhabethe, izinto zasekhishini kanye nophahla kungaboniswa ngesikhathi esisodwa sombukiso empeleni yisidingo semakethe kanye namakhasimende. Yiqiniso, ubuchwepheshe kanye nokwehlukahlukana ngokwako kuyizihloko eziye zathuthuka ngendlela ye-dialectical. Umbukiso Wekhishi Negumbi Lokugeza laseShanghai manje usungene esigabeni esisha. Kokubili umbukiso kanye namabhizinisi benza amalungiselelo okuguqulwa buthule. Lo mkhuba empeleni uyinto encane yokuguqulwa kwe-"Made in China". Kulo mbukiso owavulwa ngoJuni 3, 2015, singase sikwazi ukubona imikhondo eminingi ye-"Internet Plus", imikhondo eminingi "yobuhlakani", kanye nemikhuba emisha nengangenisi kakhulu.
