Ubushyuhe bwinshi bwa Graphite Heating Element: Ni iki kiyigabanya mu mwuka ugereranije n'ubushyuhe bw'umwuka?

Ibintu bishyushya bya grafiti, nk'ibikoresho bishyushya ubushyuhe bwinshi, bikoreshwa cyane mu nganda nyinshi, harimo ibyuma, ibikoresho by'ikoranabuhanga, ibikoresho bya semiconductor, n'ibinyabutabire. Ibikoresho bya grafiti bifite ubushobozi bwo gutwara ubushyuhe bwiza, birwanya ubushyuhe bwinshi, kandi bikagira ubushobozi bwo kudahindagurika mu binyabutabire, bigatuma bikomeza gukora neza igihe kirekire, cyane cyane mu bidukikije bishyushya cyane. Ariko, ubushyuhe ntarengwa bw'ibikoresho bishyushya grafiti buterwa n'ibintu bitandukanye, aho ubushyuhe bugarukira hagati y'ikirere n'ikirere gishyushya.

Muriikirere gikikije, ubushyuhe ntarengwa bw'ibintu bishyushya bya grafiti bugengwa na ogisijeni. Iyo ikintu gishyushya cya grafiti gishyushye ku bushyuhe bwinshi, gihura na ogisijeni mu kirere kikarema dioxyde de carbone (CO₂) cyangwa monoxide de carbone (CO₂). Iyi nzira yo gushyushya ituma ibintu byangirika buhoro buhoro no kugabanuka k'imikorere, amaherezo bigira ingaruka ku buzima bw'ikintu gishyushya. Ubusanzwe, mu kirere gisanzwe, ubushyuhe ntarengwa bw'ibintu bishyushya bya grafiti buri hafi.3000°CKurenza ubu bushyuhe byihutisha umuvuduko wa oxidation, bigatera kwangirika vuba kw'ibikoresho.

Bitandukanye n'ikirere, muahantu hadafite umwuka uhagije, ogisijeni iragabanuka neza. Mu gikoresho cy'umwuka, igipimo cya ogisijeni kiba hafi ya zeru, bityo nta ogisijeni iba ku buso bwa graphite. Ibi bituma ibikoresho bya graphite bihangana n'ubushyuhe bwinshi cyane. Mu by'ukuri, mu gikoresho cy'umwuka, ubushyuhe ntarengwa bwa graphite bushobora kugera kuri3500°Ccyangwa hejuru, ubushyuhe budashobora kugerwaho mu kirere. Ibyiza byo gukoresha ikirere cyuzuyemo umwuka ntibiri mu kugenzura ubwiyongere bw'umwuka gusa, ahubwo binari mu gutuma ubushyuhe buguma neza kandi bugakomeza kubaho igihe kirekire. Ibi bituma ibikoresho bishyushya bya grafiti biba byiza cyane mu bikorwa bishyushya cyane, nko mu gukora semiconductor na sisitemu zo gushyushya mu kirere, aho akenshi bikora mu gihe cy'umwuka w ...

Uretse ogisijeni, imbaraga z'ubushyuhe bwinshi za grafiti zigira uruhare runini mu kugena aho ubushyuhe bugarukira. Uko ubushyuhe bwiyongera, icyuma cya grafiti gishobora guhinduka gato, cyane cyane iyo ubushyuhe burenze urugero runaka. Ibi bishobora gutuma ubushyuhe bwaguka cyangwa hagashibuka uduce duto. Izi mpinduka zifatika ntizigira ingaruka gusa ku miterere ya grafiti ahubwo zishobora no kugabanya ubushyuhe burambye bw'ikintu gishyushya. Kubwibyo, kuramba kwa grafiti ku bushyuhe butandukanye ni ikintu cy'ingenzi mu kumenya niba ishobora gukora mu mutekano no mu buryo bunoze mu bidukikije runaka.

Mu kirere cy’ubushyuhe bukabije, ibintu bishyushya bya grafiti bishobora kugera ku bushyuhe bwinshi cyane kuko nta ogisijeni ibaho yo kwangiza ibikoresho. Byongeye kandi, mu gikoresho gishyushya, kohereza ubushyuhe birakora neza, kuko grafiti ishobora kohereza ubushyuhe neza ku gikoresho cy’akazi nta kubangamira ogisijeni. Ibi bituma ibintu bishyushya bya grafiti biba byiza gukoreshwa mu itanura rishyushya, gushonga kwa laser, sisitemu zo gushyushya ahantu, n’izindi porogaramu zikoresha ubushyuhe bwinshi.

Ariko, nubwo ibidukikije bikoresha umwuka udafite ubushyuhe bwinshi bifite ibyiza byinshi, hari ibindi bintu bigomba kwitabwaho mu gihe hakoreshwa ibikoresho bya grafiti mu mwuka udafite ubushyuhe. Urugero, uburyo ubushyuhe bwa grafiti bushobora guhinduka gato bitewe n'ihindagurika ry'umuvuduko wa gaze. Kubwibyo, kugenzura ubushyuhe bw'ibintu bishyushya grafiti mu bihe bitandukanye bidafite ubushyuhe bigomba guhindurwa hashingiwe ku bihe runaka. Byongeye kandi, nubwo oxidation ikumirwa mu mwuka udafite ubushyuhe, imimerere ikabije nko gusohora arc ishobora kugira ingaruka ku ituze no kuramba kwa grafiti.

Muri make, itandukaniro riri hagati y'ubushyuhe n'ingano yaibintu bishyushya bya grafitiMu kirere no mu bidukikije byuzuye umwuka bigaragaza imikoranire ikomeye iri hagati y’imiterere y’ibintu n’ibidukikije. Oxidation mu kirere ni cyo kintu cy’ingenzi kigabanya ubudahangarwa bwa grafiti mu bushyuhe bwinshi, mu gihe ibidukikije byuzuye umwuka bitanga urubuga rudakoresha oxidation, rutuma grafiti ikora mu bushyuhe bwinshi cyane. Mu guhitamo ibintu bishyushya grafiti mu bikorwa byihariye, ni ngombwa gusuzuma ibidukikije kugira ngo ufate icyemezo cyo gukoresha umwuka cyangwa ushyushya vacuum. Ku bushyuhe bushyuha cyane kandi burambye, ibintu bishyushya grafiti mu bidukikije byuzuye umwuka nta gushidikanya ko ari byiza kurushaho.
