10. Kupfuura Kuchenesa: Kuongorora Yepamberi Yepamberi Kurapa Kwekumusoro Kwemagetsi Emagetsi Electrodes?

Ndichiri kuchena kuchenesa kuchenesa zvivakwa zveGraphite Electrode, dzimwe nguva zvikumbiro zvinoda zvinovandudzwa maitiro ekuita. Izvi zvakaita kuti ubudirire kwekukura kwakakura kwepamusoro marapirwo uye kuchinjiswa. Izvi zvinopfuura kungochenesa iyopamusorouye chinangwa chekuchinja zvakakoshachivakwambiri yezvakanyanya zvakanaka. NgatiiteiOngororaMienzaniso mishoma:

• Anti-Oxidation Coatings:Graphite inowanzoitaoxidizepakupisa kwakanyanya pamberi pemhepo, inotungamira kuwandakushandiswa, kunyanya mune eafs kana zvimwe zvakakwirira-tembiricha maitiro. Inoshandisa majasi akasarudzika (i.e., zvichibva panesiliconcarbide, Alumina, kana zvimwe zvinhu zvekudzora) zvinogona kuumba chipinganidzo chekudzivirira, zvakanyanya kuderedza oxidation kurasikirwa uye kuwedzeraElectrodeHupenyu. Aya machira anoda kusarudzwa nokungwarira kuti ave nechokwadi chekuti havakwanisi kukanganisa magetsi maitiro kana kusvibisa nyungudi.
• Surventization (Electrochemical):ForElectrochemicalkunzwa uye catalyr, iyoGraphite Electrode pamusoroinogona kushandurwa nemaune kusimudzira maitiro ayo. Izvi zvinogona kusanganisira:
  • Electrochemicalkuiswa kweMetallicNAANOPATCICCICCLICICCLICCLICLESS (segoridhe kana platinum) kuti catelze chaiyo maitiro.
  • Kuvhara kubatana kwemamorekuru kana polymers kuti vagadzire masisitimu ekusunga masisitari ekuongorora vane hanya.
  • Plasma kurapwa kusuma mapoka anoshanda (kunge okisijeni kana nitrogen mapoka) iyo inoshandura mamiriro ekunze uye kudyidzana neElectrolytekana kuita.
    Izvi zvinoshandurwa zvine chinangwa chekuvandudza pfungwa, kusarudza, kana maitiro ekutsanangura kune yakatarwaElectrochemicalzviyero, zvichisundira miganhu kupfuura iyo iri nyore kupukutwaGraphite Electrodeinogona kuzadzisa. Tinowanzoona amaitirotakananga kudyarwaElectrode mafichamune yakakwirakuongororwaChemistry.
• Kusimbisa:Mamwe magiramu emakiromita anogona kunge akasungwa nezvinhu zvakaita seyenzi kana pitch isati yapera kupora uye kubhejera kuti ideredze kukanganisa uye kugadzirisa simba kana oxidation kuramba. Nepo kazhinji chikamu chechiitiko chekugadzira, post-kurapa zvinosanganisira kusawirirana nezvinhu zvakajeka (kunge mhangura kweicho chinyoreso mune mamwe maitiro ekurwisa) anowedzeredzwawo, kunyangwe akaomeserwa zvakajairikaGraphite Electrodes.

Aya marapirwo epamberi anomiririra mhinduro dzakasarudzika dzakagadzirirwa kumatambudziko chaiwo. Ipo mamiriro ekuchenesa anotarisa pane kuchengetedza iyo baseline mashandiro ezvigadzirwa sengeUHP Graphite Electrodeskanagraphite mablock. Izvi zvinopa zvakakoshaInsightmukuenderera mberi kwehuwandu mukati megirazi regiramu. Iko kusarudzwa uye kushandiswa kwezvibodzwa izvi zvinoda hunyanzvi hwakakosha kuona kuti vanoratidza izvo zvinobatsira pasina kuunza matambudziko matsva.

Key kubvisa electrode kuchenesa uye kugadzirisa:

• Kuchena kuri kutsoropodza:AkachenaGraphite Electrode pamusoroyakakosha kune yemagetsi emagetsi ekuita, akadererakushandiswa, kuenderana kwekuita (mune eafs), uye kwakaruramaElectrochemicalzviyero (zvakapinzaPeak, yakavimbikachiratidzo).
• Ziva zvako zvinomutsa:Ziva zvingangoitika zvekutsamwa (mafuta nemvura, guruva, process) kusarudza nzira chaiyo yekuchenesa.
• Shandisa zvishandiso zvakakodzera:Shandisa zvinyoro nyoro, machira-emahara-emahara, sol sol soles (IP, acetone, di mvura), uye giya rekuchengetedza. Dzivisa zviito zvehurombo zvisina kujairika kunze kwekunge zvichidikanwa uye zvakaitwa nokungwarira.
• Tevedza maitiro ezvemiti:Kuongorora, kuomachenesa (Akamanikidzwa Mhepo),geza(Solvent Wipe / Rinse), pukuta zvakakwana, uye kuongorora-kuongorora. Chengetedza tambo.
• Funga ultrasonic zvishoma:Inobatsira yekuchenesa yakadzika asi kushandiswa nekungwarira kuti udzivisekukuvara. Dzora nguva uyeRinseZvakanaka.
• Electrochemical prep iri kuomarara:Inoda kupukuta (Alumina /daimani), kunyatsochinja, kazhinjiUltrasonickuchenesa, uye dzimwe nguvaElectrochemicalactivation kuti uwane kuberekapamusoro. Tarisa neCVPeakkuongororwa.
• Dzivirira Kukuvara:Bata nokungwarira, dzivirira tambo, shandisa zvakaringanatorque, dzivisa kupisa kwakanyanya, uye tarisa makemikari kuenderana. Kudzivisa kudzivisa kiyi.
• Simbisa kuchena:Shandisa Kuongorora Kwekuona, Pukuta bvunzo, uye neElectrochemicalShanda, CV Kuedza.
• Chengetedza uye ubate zvakanaka:Chengetedza maElectrodes yakachena, yakaoma, yakachengetedzwa (kunyanya tambo), uye kubata nemidziyo yakachena / magurovhosi kuti udzorezve kusvibiswa.
• Kurapa Kwepamberi Kunoripo:Coatings uye mashandiro anogona kusimudzira zvivakwa senge oxidation kuramba kanaElectrochemicalchiitiko chezvinodiwa chaizvo.

Nekuita izvi nhungamiro, vashandisi veGraphite ElectrodesInogona kuona kuti vanowana zvakanakisa kuita uye hupenyu hwekuita kubva pane izvi zvakashata zvikamu, kuderedza nyaya dzekushanda uye kuwedzera kushanda zvakanaka.
