Isesengura rishya ryamahame yo kwinjiza ubushyuhe bwa silicon karbide grafite ingirakamaro

1. Ibikoresho nibikoresho

silicon karbide grafite ingirakamaro itunganijwe mubikoresho nka grafite na silicon karbide ikoresheje inzira igoye, ikomatanya ibyiza byayo. Ibintu nyamukuru biranga grafite harimo:

 

Amashanyarazi nubushyuhe: Graphite ifite amashanyarazi meza nubushyuhe, bituma ihinduranya vuba ubushyuhe kandi igabanya gutakaza ingufu mubushyuhe bwinshi.

Imiti ihamye: Graphite ikomeza kuba itajegajega kandi irwanya imiti ikomoka kuri acide na alkaline.

Kurwanya ubushyuhe bwinshi: Graphite irashobora kugumana ubusugire bwimiterere mugihe kirekire mubushyuhe bwo hejuru nta mpinduka zikomeye zatewe no kwaguka kwinshi cyangwa kugabanuka.

Ibintu nyamukuru bya karubide ya silicon harimo:

 

Imbaraga za mashini: Carbide ya Silicon ifite ubukana bwinshi nimbaraga za mashini, kandi irwanya kwambara ningaruka.

Kurwanya ruswa: Yerekana uburyo bwiza bwo kurwanya ruswa mu bushyuhe bwo hejuru no mu kirere cyangirika.

Ubushyuhe bwumuriro: Carbide ya Silicon irashobora kugumana imiterere ihamye yimiti niyumubiri mubushyuhe bwo hejuru.

Guhuza ibi bikoresho byombi biremasilicon karbide grafite ingirakamaros, ifite ubushyuhe bwinshi, ubushyuhe bwiza bwumuriro hamwe nubushakashatsi bwiza bwimiti, bigatuma biba byiza mubushyuhe bwo hejuru.

 

2. Uburyo bwa chimique nuburyo bwa endothermic

silicon karbide grafite ingirakamaro ihura nuruhererekane rwimiti yubushyuhe bwo hejuru, ntibigaragaza gusa imikorere yibintu byingenzi, ahubwo ni isoko yingenzi yimikorere yubushyuhe. Ibintu nyamukuru bivura imiti birimo:

 

Redox reaction: Okiside yicyuma ifata hamwe nikintu kigabanya (nka karubone) mubikomeye, ikarekura ubushyuhe bwinshi. Kurugero, okiside ya fer ikora hamwe na karubone ikora fer na karuboni:

 

Fe2O3 + 3C→2Fe + 3CO

Ubushyuhe bwarekuwe niyi reaction bwakirwa ningirakamaro, bikazamura ubushyuhe bwabwo muri rusange.

 

Pyrolysis reaction: Ku bushyuhe bwinshi, ibintu bimwe na bimwe bigenda byangirika bitanga molekile ntoya kandi ikarekura ubushyuhe. Kurugero, calcium karubone ibora mubushyuhe bwinshi kugirango itange calcium oxyde na karuboni ya dioxyde:

 

CaCO3→CaO + CO2

Iyi pyrolysis reaction nayo irekura ubushyuhe, bwinjizwa nibikomeye.

 

Imyuka ya parike: Umwuka wamazi ukora hamwe na karubone mubushyuhe bwinshi kugirango ubyare hydrogène na monoxyde de carbone:

 

H2O + C.→H2 + CO

Ubushyuhe bwarekuwe niyi reaction nabwo bukoreshwa ningirakamaro.

 

Ubushyuhe buterwa niyi reaction yimiti nuburyo bwingenzi kurisilicon karbide grafite ingirakamaro gukuramo ubushyuhe, bikayemerera kwinjiza neza no guhererekanya ingufu zubushyuhe mugihe cyo gushyushya.

 

bitatu. Isesengura ryimbitse ryihame ryakazi

Ihame ry'akazi ryasilicon karbide grafite ingirakamaro ntabwo yishingikiriza gusa kumiterere yibintu, ahubwo yishingikiriza ahanini kumikoreshereze myiza yingufu zubushyuhe hakoreshejwe imiti. Inzira yihariye niyi ikurikira:

 

Gushyushya ingirakamaro: Inkomoko yubushyuhe bwo hanze ishyushya ingenzi, kandi ibikoresho bya grafite na silicon karbide imbere bikurura vuba ubushyuhe kandi bigera ku bushyuhe bwinshi.

 

Imiti ya chimique endothermic: Mugihe cy'ubushyuhe bwinshi, reaction ya chimique (nka redox reaction, pyrolysis reaction, reaction reaction, nibindi) bibera imbere mubikomeye, bikarekura ingufu nyinshi zubushyuhe, byinjizwa nibintu byingenzi.

 

Ubushyuhe bwa Thermal: Bitewe nubushuhe buhebuje bwumuriro wa grafite, ubushyuhe buri mukibumbano bukorwa vuba mubintu biri mubikomeye, bigatuma ubushyuhe bwayo buzamuka vuba.

 

Ubushuhe bukomeza: Mugihe imiti ikomeje kandi ubushyuhe bwo hanze bukomeza, ingenzi irashobora kugumana ubushyuhe bwinshi kandi igatanga ingufu zihoraho zubushyuhe bwibikoresho mubikomeye.

 

Ubu buryo bwiza bwo gutwara ubushyuhe hamwe nubushyuhe bwo gukoresha ingufu butuma imikorere isumba iyindisilicon karbide grafite ingirakamaro munsi yubushyuhe bwo hejuru. Iyi nzira ntabwo itezimbere gusa ubushyuhe bwingirakamaro, ahubwo inagabanya gutakaza ingufu, bigatuma ikora neza cyane mubikorwa byinganda.

 

Bane. Porogaramu zishyashya hamwe nicyerekezo cyiza

Imikorere isumba izindi yasilicon karbide grafite ingirakamaro mubikorwa bifatika ahanini biri muburyo bukoreshwa neza bwingufu zumuriro no gutuza kubintu. Ibikurikira nuburyo bushya bwo gukoresha hamwe nicyerekezo cyiza cyo gutezimbere:

 

Gushonga ibyuma byo hejuru cyane: Muburyo bwo gushonga ibyuma byo hejuru,silicon karbide grafite ingirakamaro irashobora kunoza neza umuvuduko wo gushonga hamwe nubwiza. Kurugero, mugushongesha ibyuma, umuringa, aluminiyumu nibindi byuma, icyuma kinini cyumuriro mwinshi hamwe no kurwanya ruswa gishobora gutuma gihanganira ingaruka zicyuma gishushe cyane, bikarinda umutekano numutekano wibikorwa byo gushonga.

 

Imiyoboro yubushyuhe bwo hejuru yubushyuhe:silicon karbide grafite ingirakamaro irashobora gukoreshwa nkigikoresho cyiza kubushyuhe bwo hejuru bwimiti. Kurugero, mu nganda zikora imiti, ibintu bimwe na bimwe byerekana ubushyuhe bwo hejuru bisaba imiyoboro ihamye kandi idashobora kwangirika, hamwe nibirangasilicon karbide grafite ingirakamaros byuzuye byuzuye.

 

Gutezimbere ibikoresho bishya: Mubushakashatsi no guteza imbere ibikoresho bishya,silicon karbide grafite ingirakamaro irashobora gukoreshwa nkibikoresho byibanze byo gutunganya ubushyuhe bwo hejuru hamwe na synthesis. Imikorere ihamye hamwe nubushyuhe bwiza bwumuriro bitanga ibidukikije byiza byubushakashatsi kandi biteza imbere iterambere ryibikoresho bishya.

 

Ingufu zo kuzigama no kugabanya imyuka yangiza: Mugutezimbere imiterere yimiti yasilicon karbide grafite ingirakamaro, imikorere yubushyuhe irashobora kurushaho kunozwa no gukoresha ingufu bigabanuka. Kurugero, kwinjiza catalizator mubikomeye byizwe kugirango hongerwe imikorere ya redox reaction, bityo bigabanye igihe cyo gushyushya no gukoresha ingufu.

 

Guteranya ibikoresho no kubihindura: Gukomatanya nibindi bikoresho bikora cyane, nko kongeramo fibre ceramic cyangwa nanomaterial, birashobora kongera ubushyuhe bwimbaraga nimbaraga za mashini zasilicon karbide grafite ingirakamaros. Byongeye kandi, binyuze muburyo bwo guhindura nko kuvura hejuru yubuso, kurwanya ruswa hamwe nubushyuhe bwumuriro wa crucable birashobora kurushaho kunozwa.

 

5. Umwanzuro hamwe nigihe kizaza

Ihame rya endothermic ofsilicon karbide grafite ingirakamaro ni ugukoresha neza ingufu zubushyuhe bushingiye kumiterere yibintu hamwe na reaction ya chimique. Gusobanukirwa no kunonosora aya mahame bifite akamaro kanini mugutezimbere umusaruro winganda nubushakashatsi bwibikoresho. Mugihe kizaza, hamwe niterambere ryiterambere ryikoranabuhanga hamwe niterambere rihoraho ryibikoresho bishya,silicon karbide grafite ingirakamaros biteganijwe kugira uruhare runini murwego rwo hejuru-ubushyuhe bwimirima.

 

Binyuze mu guhanga udushya no gutezimbere,silicon karbide grafite ingirakamaro izakomeza kunoza imikorere no guteza imbere inganda zijyanye. Mubushyuhe bwo hejuru bwo gushonga ibyuma, ubushyuhe bwo hejuru bwimiti, hamwe niterambere rishya,silicon karbide grafite ingirakamaro bizahinduka igikoresho cyingirakamaro, gifasha inganda zigezweho nubushakashatsi bwa siyansi kugera ahirengeye.
