Electrode za grafiti zifite imbaraga nyinshi cyane zakoreshejwe cyane muri ibi bikurikira:
1. Ibyuma bya grafiti byo gucukura ibyuma bidakoresha feri mu buryo buhoraho no mu buryo burambye
Mu myaka ya vuba aha, uburyo bwo gukora bugezweho nko gukora imigozi cyangwa imiyoboro ikomoka mu byuma bishongeshejwe bwatejwe imbere mu gihugu no mu mahanga. Ubu buryo bwatangiye gukoreshwa mu Bushinwa mu bintu nk'umuringa, umuringa, aluminiyumu na aluminiyumu. Grafiti y'ubukorano ifatwa nk'ibikoresho bikwiriye cyane mu gukora ibumba rihoraho cyangwa rihoraho ry'ibyuma bidakoresha feri. Uburyo bwo gukora bwagaragaje ko bitewe no gukoresha ibumba rya grafiti, rifite ubushobozi bwo gutwara ubushyuhe bwiza (uburyo bwo gutwara ubushyuhe bugena umuvuduko wo gukomera kw'ibyuma cyangwa aloyi) hamwe n'imikorere myiza yo kwisiga ibumba, umuvuduko wo gutwika wiyongera gusa, ahubwo no kubera ko ingano y'ibumba ari nziza, ubuso buroroshye, kandi imiterere ya kristu isa, uburyo bukurikira bwo gutunganya bushobora gukorwa mu buryo butaziguye. Ibi ntibyongera cyane umusaruro w'ibicuruzwa byarangiye kandi bigabanya igihombo cy'imyanda, ahubwo binanoza cyane ubwiza bw'ibicuruzwa.
Hari ubwoko bubiri bw'uburyo bwo gucukura bukomeza: gucukura bihoraho bihagaze n'ugucukura bihoraho bihagaze.
2. Ibikoresho byo gusuka igitutu
Ibikoresho bya grafiti y'ubukorano byakoreshejwe neza mu gucukura ibyuma bidafite feri. Urugero, ibikoresho bya zinc alloy na alloy by'umuringa byakozwe n'ibibumbano bicukura pressure byakozwe mu bikoresho bya grafiti y'ubukorano byakoreshejwe mu bice by'imodoka no mu bindi bice.
3. Agakoresho gashyushye gakanda
Ibyuma bishyushye bya grafiti by’ubukorano bifite ibi bikurikira iyo bikoreshejwe mu gutwika umuvuduko wa carbide ikozwe muri sima:
Ubwa mbere, niba ubushyuhe bwo gukanda buzamuwe bukagera kuri dogere 1350-1450, igitutu gikenewe gishobora kugabanuka kikagera kuri kilogarama 67-100 kuri santimetero kare imwe (ni ukuvuga kimwe cya cumi cy'igitutu cyo gukanda gikonje). Icya kabiri, gukanda no gushyushya bikorwa muri ubwo buryo, kandi umubiri munini urimo gukanda ushobora kuboneka nyuma y'igihe gito cyo gukanda.
4. Ibikoresho byo gukora ikirahure
Bitewe n’uko ibikoresho bya grafiti bigumana ubuziranenge, ubushobozi bwabyo bwo kudatoserwa n’ibirahuri bishongeshejwe, ndetse no kuba bidahindura imiterere y’ibirahuri, ndetse no kudahinduka kw’ubushyuhe n’impinduka nto mu bushyuhe, byahindutse ibikoresho by’ingenzi mu gukora ibirahuri mu myaka ya vuba aha. Bishobora gukoreshwa mu gukora ibirahuri bikoreshwa mu miyoboro y’ibirahuri, imiyoboro y’inkokora, imiyoboro y’amazi, n’andi macupa atandukanye y’ibirahuri afite ishusho yihariye.
5. Imfu zikora sintering n'izindi
Hashingiwe ku kuntu ibikoresho bya grafiti by’ubukonje bito cyane bishobora guhinduka, hashobora gukorwa imashini zicana n’udukingirizo twa transistors. Ubu irakoreshwa cyane kandi yabaye ibikoresho by’ingenzi mu iterambere ry’inganda za semiconductor. Byongeye kandi, imashini za grafiti zikoreshwa kandi mu imashini zicana, imashini ziramba ku byuma bitandukanye bidakoresha feri, imashini zicana mu byuma bicuzwe, imashini zicana mu byuma bicuzwe bidashyuha (nka titaniyumu, zirconium, molybdenum, nibindi), n’imashini zicana aluminothermic zo gusudira ku nsinga zo gusudira, nibindi.
6. Ibikoresho bya grafiti byo gucukura mu buryo bwa centrifugal
Grafiti y'ibimera yakoreshejwe neza mu gucukura centrifugal. Leta Zunze Ubumwe za Amerika zakoresheje ibumba rya grafiti ry'ubukorano rifite ubugari bw'urukuta burenga milimetero 25 mu gucukura centrifugal mu maboko y'umuringa. Kugira ngo hirindwe kwangirika kw'ibumba rya grafiti ry'ubukorano, ingamba zimwe na zimwe zo kurwanya oxidation zishobora gufatwa. Nyuma yo gucukura umubare runaka w'ibumba, niba ubuso bw'imbere bw'ibumba bugaragaye ko bwahiye, ingano y'umwobo w'imbere w'ibumba ishobora kwaguka kugira ngo ikoreshwe mu gucukura intoki nini. Qingdao Mingyuan Fengyue New Materials ni ubwoko bushya bw'ikigo gitunganya grafiti gifite ifu ya grafiti nziza cyane nk'umubiri wacyo mukuru n'ibicuruzwa bya grafiti by'ikoranabuhanga rihanitse nk'umusaruro wacyo ukomeye. Yashinze umubano w'ubufatanye mu gihe kirekire n'ibigo birenga 200 byo mu gihugu no mu mahanga kandi yashimwe cyane n'abayikoresha benshi.
Ifu ya grafiti ya nanometer ikorwa muri grafiti karemano nk'ibikoresho fatizo, igatunganywa hakoreshejwe ibikoresho byihariye byo gusya no gukora ibikoresho byihariye. Nk'ifu ya grafiti ya nanoscale, ifu ya grafiti ya nanometer ifite uburyo bwinshi bwo kuyikoresha kubera ingano nto y'uduce twayo, ingano nini ya karuboni, n'ubushobozi bwo gusya neza, amashanyarazi menshi, ubushobozi bwo kurwanya ubushyuhe bwinshi, nibindi. Uburyo ifu ya nano-graphite ikoreshwamo buri mu nganda nko gusya no gutwara.
Uduce twa grafiti ya nanometero ni twiza kandi dufite ubucucike bwiza bw'uduce. Dukora urwego rukomeye kandi rudashaje rurinda amashanyarazi rufatanye n'ubuso bw'icyuma. Rushobora kandi kuvangwa n'ibikoresho bidashaje amashanyarazi nka resini n'ibicuruzwa bya kabutike na pulasitiki kugira ngo hakorwe ibikoresho bishaje amashanyarazi. Grafiti ya nanometero ishobora kandi gukorwamo utwenda dushaje amashanyarazi. Utwenda dushaje amashanyarazi duboneka hakongewemo utwuma dushaje amashanyarazi dufite imiterere ihamye kandi ihamye y'amashanyarazi. Ifite ibyiza byo gutwara neza ubushyuhe, gutwara neza amashanyarazi no kurwanya ingese nyinshi cyane. Grafiti ya nanometero ifite ingano imwe y'uduce, ubuziranenge bwinshi, n'imikorere yo hejuru y'ubuso. Ifite kandi imikorere myiza y'amashanyarazi no gusiga amavuta, ndetse no kudashaje cyane, kudashaje neza, no kudashaje neza kw'ifu ya grafiti. Kubwibyo, ikoreshwa ry'ifu ya grafiti ya nanometero ni rinini cyane mu nganda.
Gukoresha ifu ya nano-grafiti mu gusana bateri zo kubikamo nabyo ni byinshi cyane. Kongera nano-grafiti muri bateri zakoreshejwe bishobora kongera ubushobozi bwazo bwo kubikamo kugeza ku kigero cya 90% by'ibya mbere kandi bikongera igihe cyo kuzikoresha nibura umwaka umwe. Ibi bigabanya cyane ikiguzi cyo gukoresha bateri zo kubikamo kandi binagira uruhare runini mu kurwanya umwanda wa bateri no kurengera ibidukikije.
Ifu ya grafiti ifite uburyo bwinshi bwo kuyikoresha mu nganda. Ishobora gukoreshwa mu nganda zitandukanye. Imikoreshereze itandukanye y’ifu ya grafiti ituma habaho ibiciro bitandukanye. Ifu ya grafiti igira ingaruka nziza mu nganda nko gusiga amavuta mu nganda, gukoresha ibyuma, gutwara ibintu, n’ibikoresho birwanya ubushyuhe. Ibintu nk’ikoreshwa, ingano y’uduce, n’ubwoko bw’ifu ya grafiti byose bishobora kugira ingaruka ku giciro cyayo.
Ikoreshwa ry'ifu ya grafiti riratandukanye, bityo hari ubwoko bwinshi bw'ifu ya grafiti. Ubwoko butandukanye bw'ifu ya grafiti bufite ibiciro bitandukanye. Grafiti ya flake ishobora gutunganywamo ifu ya grafiti ifite imiterere itandukanye n'ingano zitandukanye z'uduce binyuze mu bikoresho bitandukanye byo gusya no gukora. Nk'uruganda rukora ifu ya grafiti, imiterere y'ifu ya grafiti ikorwa iri hagati ya mesh 80 na mesh 15000. Ifu ya grafiti ifite imiterere itandukanye n'ingano z'uduce, kimwe n'igiciro cyayo. Nyuma yo gutunganywa hakoreshejwe ubuhanga bwo gukora, ifu ya grafiti ifite amavuta meza, irwanya ubushyuhe bwinshi, itwara amashanyarazi, irwanya ingese, nibindi. Ifu ya grafiti nayo ishobora kugira uruhare rungana mu nzego zitandukanye z'umusaruro w'inganda.
Ubwoko bw'ifu ya grafiti burimo: Ifu ya grafiti ya Flake, ifu ya grafiti ya ultrafine, ifu ya nano grafiti, grafiti ya colloidal, grafiti yagutse, grafiti ishobora kwaguka, grafiti y'ifu nto, n'ibindi, iyi fu ya grafiti yose itunganywa hakoreshejwe uburyo butandukanye bwo kuyikora, kandi ikoreshwa ryayo naryo riratandukanye. Ifu ya grafiti ikoreshwa mu bikorwa by'amavuta yo kwisiga, amavuta akomeye, ibikoresho byo gutwika bya grafiti, amatafari arefractory, electrodes za grafiti, uburoso, electrodes za bateri, nibindi. Byose bifite akamaro kanini cyane.
