Uburyo bwo gukora electrode ya grafiti

Uburyo bwo gukora ibikoresho fatizo n'uburyo bwo gukora electrode ya grafiti

Electrode ya grafiti ni ibikoresho bitwara amashanyarazi bya grafiti bidashyuha cyane bikorerwa mu gukurura peteroli, gukurura ifu y’ibinyampeke nk’ibirungo n’ibinyampeke by’amakara nk’ibifunga, bikorerwa mu buryo butandukanye nko gukurura, gucura, gukaranga, gutera impregnation, gushushanya no gutunganya ibikoresho hakoreshejwe ikoranabuhanga.

Electrode ya grafiti ni igikoresho cy'ingenzi gitwara ubushyuhe bwinshi mu gukora ibyuma by'amashanyarazi. Electrode ya grafiti ikoreshwa mu kwinjiza ingufu z'amashanyarazi mu itanura ry'amashanyarazi, kandi ubushyuhe bwinshi buva mu gice kiri hagati y'impera y'amashanyarazi n'umushari bukoreshwa nk'isoko y'ubushyuhe mu gushongesha umushari mu gukora ibyuma. Andi matanura y'amabuye y'agaciro ashongesha ibikoresho nka fosifore y'umuhondo, silikoni y'inganda, n'ibintu bitera ubushyuhe nabyo bikoresha electrode ya grafiti nk'ibikoresho bitwara ubushyuhe. Imiterere myiza kandi yihariye ya electrode ya grafiti nayo ikoreshwa cyane mu zindi nganda.

Ibikoresho fatizo byo gukora electrode za grafiti ni coke ya peteroli, coke y'inzoga n'umushongi w'amakara.

Coke ya peteroli ni ikintu gikomeye gishobora gushya kiboneka hakoreshejwe ibisigazwa by'amakara n'ubutare bwa peteroli. Ibara ni umukara kandi rifite imyenge, ikintu nyamukuru ni karuboni, kandi ivu ririmo ni rito cyane, muri rusange riri munsi ya 0.5%. Coke ya peteroli iri mu bwoko bwa karuboni yoroshye gukoresha. Coke ya peteroli ifite uburyo bwinshi bwo kuyikoresha mu nganda zikora imiti n'ibyuma. Ni yo mashini nyamukuru ikoreshwa mu gukora ibikoresho bya grafiti y'ubukorano n'ibikomoka kuri karuboni bya aluminiyumu ikoresha amashanyarazi.

Coke ya peteroli ishobora kugabanywamo ubwoko bubiri: coke mbisi na coke ya calcium bitewe n'ubushyuhe bwo kuvura ubushyuhe. Coke ya kera ya peteroli iboneka hakoreshejwe coking yatinze iba irimo ingano nini y'ibintu bihinduka, kandi imbaraga za mekanike ni nke. Coke ya calcium iboneka hakoreshejwe calcium ya coke mbisi. Inganda nyinshi zo mu Bushinwa zikora coke gusa, kandi ibikorwa byo gukaraba ahanini bikorerwa mu nganda za karuboni.

Coke ya peteroli ishobora kugabanywamo coke nyinshi ya sulfur (irimo sulfur irenga 1.5%), coke ya sulfur iciriritse (irimo sulfur irenga 0.5%-1.5%), na coke ya sulfur iciriritse (irimo sulfur irenga 0.5%). Umusaruro wa electrodes za grafiti n'ibindi bicuruzwa bya grafiti by'ubukorano muri rusange bikorwa hakoreshejwe coke nke ya sulfur.

Ifu ya Needle coke ni ubwoko bwa coke nziza cyane ifite imiterere igaragara ya fibre, coefficient yo kwaguka k'ubushyuhe buke cyane kandi yoroshye gukoresha graphitization. Iyo coke yacitsemo ibice, ishobora kugabanywamo uduce duto bitewe n'imiterere (ubusanzwe igipimo cy'imiterere kiri hejuru ya 1.75). Imiterere ya fibre ya anisotropic irashobora kugaragara hifashishijwe mikorosikopi ya polarizing, bityo ikaba yitwa needle coke.

Imiterere ya anisotropi y’imiterere ya fiziki n’iy’imashini ya needle coke iragaragara cyane. Ifite amashanyarazi n’ubushyuhe bwiza bihuye n’icyerekezo kirekire cy’agace, kandi ingano y’ubushyuhe iba nto. Mu gihe cyo gushushanya extrusion, umurongo muremure w’agace kenshi ushyirwa mu cyerekezo cyo gusohora. Kubwibyo, needle coke ni cyo gikoresho cy’ingenzi mu gukora electrodes za grafiti zifite ingufu nyinshi cyangwa ultra-high-power. Electrode ya grafiti ikorwa ifite ubushobozi buke bwo kugabanya ubushyuhe, ingano nto yo gukura kw’ubushyuhe kandi irwanya ubushyuhe neza.

Ifu ya Needle coke igabanyijemo ifu ya needle coke ikomoka ku mavuta ikorwa mu bisigazwa bya peteroli n'ifu ya needle coke ikomoka ku makara ikorwa mu bikoresho fatizo by'amakara byatunganyijwe.

Ifu y'amakara ni kimwe mu bicuruzwa by'ingenzi mu gutunganya ifu y'amakara mu buryo bwimbitse. Ni uruvange rw'ibintu bitandukanye bya hydrocarbon, by'umukara ku bushyuhe bwinshi, bito cyangwa bikomeye ku bushyuhe bwinshi, nta ntera ihamye yo gushonga, byoroshye nyuma yo gushyuha, hanyuma bigashonga, bifite ubucucike bwa 1.25-1.35 g / cm3. Dukurikije aho yoroshye, igabanyijemo ubushyuhe buke, ubushyuhe buri hagati n'ubushyuhe buri hejuru. Umusaruro wa asphalt ku bushyuhe buri hagati ni 54-56% bya fu y'amakara. Imiterere ya fu y'amakara iragoye cyane, ifitanye isano n'imiterere ya fu y'amakara n'ingano ya heteroatoms, kandi ikagira ingaruka no ku buryo bwo gutunganya ifu y'amakara n'imiterere y'ifu y'amakara. Hari ibimenyetso byinshi bigaragaza ubushyuhe bwa fu y'amakara, nko gukamura bitumen, toluene insoluble (TI), quinoline insoluble (QI), agaciro ka coking, na rheology ya fu y'amakara.

Karuboni ikoreshwa nk'icyuma gifunga kandi gitera imyuka mu nganda za karuboni, kandi imikorere yayo igira ingaruka zikomeye ku musaruro n'ubwiza bw'ibicuruzwa bya karuboni. Karuboni ifunga muri rusange ikoresha karuboni ihindura ubushyuhe buri hagati cyangwa ubushyuhe buri hagati ifite aho yoroshya, agaciro kayo ko guconga cyane, na resin ya β nyinshi. Itera imyuka ni karuboni ikoresha ubushyuhe buri hagati ifite aho yoroshya, QI nke, n'imiterere myiza ya rheological.
