Kodi ndi zinthu ziti zomwe zimakhudza kukana kwa okosijeni kwa ma electrode a graphite?

Kukana kwa okosijeni kwa ma electrode a graphite kumakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo kutentha, kuchuluka kwa okosijeni, kapangidwe ka kristalo, katundu wa ma electrode (monga digiri ya graphitization, kuchuluka kwa ma bulk, ndi mphamvu ya makina), kapangidwe ka ma electrode (monga khalidwe la malumikizano ndi kuyanjana kwa kutentha), ndi chithandizo cha pamwamba (monga zophimba antioxidant). Zotsatirazi ndi kusanthula mwatsatanetsatane kwa zinthu izi:

1, Kutentha:
Kuchuluka kwa okosijeni kwa ma electrode a graphite kumawonjezeka kwambiri kutentha kukakwera. Kupitirira 450°C, graphite imayamba kuchitapo kanthu mwamphamvu ndi mpweya, ndipo kuchuluka kwa okosijeni kumawonjezeka kwambiri kutentha kukapitirira 750°C.
Pa kutentha kwambiri, zochita za mankhwala pamwamba pa graphite zimakhala zolimba kwambiri, zomwe zimapangitsa kuti okosijeni achuluke. Mwachitsanzo, mu uvuni wamagetsi, kutentha kwa pamwamba pa electrode kumatha kupitirira 2000°C, zomwe zimapangitsa kuti okosijeni akhale chifukwa chachikulu chogwiritsira ntchito electrode.

2, Kuchuluka kwa mpweya:
Kuchuluka kwa okosijeni ndi chinthu chofunikira kwambiri chomwe chimakhudza kuchuluka kwa okosijeni m'ma electrode a graphite. Pa kutentha kwambiri, kuyenda kwa kutentha kwa mamolekyulu a okosijeni kumawonjezeka, zomwe zimapangitsa kuti azigundana ndi graphite ndikulimbikitsa kusintha kwa okosijeni.
M'malo opangira mafakitale monga ma arc ng'anjo zamagetsi, mpweya wambiri umalowa kudzera m'mabowo a ma electrode ndi zitseko za ng'anjo, zomwe zimapangitsa kuti mpweya ulowe ndikuwonjezera kukhuthala kwa ma electrode.

3, Kapangidwe ka Crystal:

Kapangidwe ka kristalo ka graphite ndi kotayirira ndipo kamatha kuukiridwa ndi maatomu a okosijeni. Pa kutentha kwambiri, kapangidwe ka kristalo ka graphite kamasintha, zomwe zimapangitsa kuti kukhazikika kuchepe komanso kuti okosijeni apitirire mofulumira.

4, Katundu wa Zinthu za Electrode:

• Mlingo wa Graphitization: Ma electrode okhala ndi digiri yapamwamba ya graphitization amasonyeza kukana bwino kwa okosijeni komanso kugwiritsa ntchito kochepa. Graphite yoyera kwambiri, yokhala ndi kutentha kwa graphitization komwe nthawi zambiri kumafika pafupifupi 2800°C, imasonyeza kukana kwa okosijeni kwambiri poyerekeza ndi ma electrode amphamvu a graphite (okhala ndi kutentha kwa graphitization pafupifupi 2500°C).
• Kuchuluka kwa Maginito: Mphamvu ya makina, elastic modulus, ndi kutentha kwa ma electrode a graphite kumawonjezeka ndi kuchuluka kwa maginito, pomwe resistivity ndi porosity zimachepa. Kuchuluka kwa maginito kumakhudza mwachindunji kugwiritsa ntchito ma electrode, ndi ma electrode okhala ndi kuchuluka kwakukulu kwa maginito akuwonetsa kukana kwa okosijeni bwino.
• Mphamvu ya Makina: Ma electrode a grafiti samangoyang'anizana ndi kulemera kwawo kokha komanso mphamvu zakunja komanso mphamvu za tangential, axial, ndi radial kutentha akamagwiritsidwa ntchito. Pamene mphamvu ya kutentha imaposa mphamvu ya makina ya electrode, ming'alu kapena ngakhale kusweka kungachitike. Chifukwa chake, ma electrode omwe ali ndi mphamvu yayikulu yamakina amakhala ndi kukana kwakukulu kutentha komanso kukana bwino okosijeni.

5, Kapangidwe ka Electrode:

• Ubwino wa Ma Joint: Ma Joint ndi malo ofooka a ma electrode ndipo amatha kuwonongeka mosavuta kuposa thupi la electrode. Zinthu monga kulumikizana kosasunthika pakati pa ma electrode ndi ma joint, ndi ma coefficients osafanana a kutentha zingayambitse kusungunuka kwa okosijeni komanso kusweka kwa ma joint.
• Kugwirizana kwa Kutentha: Ma coefficients owonjezera kutentha osagwirizana pakati pa zinthu za electrode ndi malo ozungulira angayambitsenso kusweka kwa electrode. Pamene electrode ikuwonjezeka kutentha pa kutentha kwakukulu, ngati malo ozungulira kapena zinthu zomwe zikukhudzana ndi electrode sizingakulire moyenera, kupsinjika kumachitika, zomwe pamapeto pake zimapangitsa kuti pakhale kusweka.

6, Chithandizo cha pamwamba:
Kugwiritsa ntchito zophimba zoteteza ku ma antioxidants kungathandize kwambiri kukana kwa okosijeni kwa ma electrode a graphite. Mwachitsanzo, zophimba zoteteza ku ma graphite a RLHY-305 zimapanga chophimba cholimba cha antioxidant pamwamba pa substrate, zomwe zimapangitsa kuti zikhale bwino kwambiri kutseka. Zimachotsa mpweya kuchokera ku graphite pa kutentha kwakukulu, kuletsa kuyanjana pakati pa graphite ndi mpweya, ndikuwonjezera moyo wa zinthu za graphite ndi osachepera 30%.
Kuthira mankhwala ophera tizilombo toyambitsa matenda ndi njira yothandiza kwambiri yophera tizilombo toyambitsa matenda. Mwa kuthira mankhwala ophera tizilombo toyambitsa matenda m'ma electrode a graphite kudzera mu vacuum cleaner kapena kunyowa mwachilengedwe, kukana kwa okosijeni kwa ma electrode kumatha kukulitsidwa.
