Kwinjira muri Silicon Carbide Imirasire Tube: "Impuguke Yubushyuhe Bwinshi Kurwanya Ubushyuhe" mubushuhe bwinganda

Gushyushya nintambwe yingenzi ariko ikomeye mubice byinshi byumusaruro winganda. Kuva mu gutunganya ubushyuhe bwicyuma kugeza gucumura ceramic, ndetse no gutunganya ibikoresho bimwe byihariye, ibikoresho bishyushya bihamye, bikora neza, kandi bigahinduka. Muri ibi bihe hamwe nibisabwa bikomeye kubushyuhe no kuramba,silicon carbide imirasiretubes zirimo guhitamo imishinga myinshi kandi myinshi kubera ibyiza byihariye.
Abantu bamwe bashobora kugira amatsiko, umuyoboro wa silicon karbide ni iki? Muri make, ni ikintu cyo gushyushya igituba gikozwe cyane cyane mubutaka bwa silicon carbide ceramics, ubusanzwe bukoreshwa bufatanije ninsinga zishyushya, inkoni zishyushya hamwe nibindi bikoresho byimbere, kandi bigira uruhare rw "guhinduranya ubushyuhe" mumatara yinganda nibindi bikoresho. Nyamara, umwihariko wacyo ushingiye ko idatanga ubushyuhe butaziguye, ahubwo ihinduranya ubushyuhe kumurimo ukenera gushyukwa muburyo bwimirasire binyuze mubintu bishyushya imbere bizengurutse, mugihe kandi birinda ibice byimbere mukirere kitoroshye kiri mu itanura.
Iyo bigeze ku nyungu za silicon carbide imirasire yumuriro, "ubushyuhe bwo hejuru bwo hejuru" nukuri ikirango cyacyo. Imiyoboro isanzwe yo gushyushya ibyuma irashobora guhinduka no guhinduka mubushyuhe bwa dogere selisiyusi magana, mugihe ceramika ya silicon karbide ubwayo ifite imbaraga zo guhangana nubushyuhe bwo hejuru. Ndetse no mu itanura ryubushyuhe bwo hejuru hejuru ya 1300 ℃, rirashobora kugumana imiterere ihamye kandi ntabwo ryangiritse byoroshye. Ibi biranga bituma bihuza nuburyo bwinshi bwo gutunganya ubushyuhe bwo hejuru, nkubushyuhe bwo gucumura bwibintu bimwe na bimwe by’ubutaka bwihariye burenga 1200 and, kandi imiyoboro ya radiyo ya karubide ya silicon irashobora gukora neza mubihe nkibi igihe kirekire.
Usibye kurwanya ubushyuhe bwo hejuru, "kurwanya ruswa" nabwo ni ikintu cyingenzi kibigaragaza. Mubikorwa byinshi byo gushyushya inganda, hashobora kuba harimo aside, imyuka ya alkaline cyangwa ibindi bintu byangirika mu itanura, bishobora kwangirika byoroshye ibintu bishyushya kandi bigabanya igihe cyo gukora cyibikoresho. Imiti ihamye yibikoresho bya karubide ya silicon irakomeye, kandi ntabwo byoroshye kubyitwaramo nibintu byangirika, bivuze ko ishobora gukomeza kuramba neza mumyuka itanuye, kugabanya inshuro zo gusimbuza ibikoresho, kandi mugihe kirekire, bikagabanya kandi umusaruro nogutunganya ibigo.
Byongeye kandi, "ubushyuhe bwumuriro" wa silicon karbide ya radiyoyasi nayo ikwiye kuvugwa. Ubushuhe bwumuriro ni bwiza, bushobora kwimura vuba ubushyuhe butangwa nibintu byo gushyushya imbere no gushyushya igihangano ukoresheje imirasire. Ubu buryo bwo gushyushya ntabwo bushyuha vuba gusa, ariko kandi butuma ikwirakwizwa ryubushyuhe imbere mu itanura riba kimwe, birinda ubushyuhe bwaho cyangwa ubushyuhe budahagije. Ibi nibyingenzi cyane kugirango hamenyekane ubuziranenge bwibicuruzwa bitunganijwe. Kurugero, muburyo bwo kuvura ubushyuhe bwibice byicyuma, uburinganire bwubushyuhe bugira ingaruka kuburyo butaziguye ubukana, ubukana, nibindi bintu bigize ibice, hamwe na silicon carbide imirasire irashobora gutanga inkunga ihamye muriki kibazo.

Birumvikana ko ikoreshwa rya silicon carbide imirasire yimirasire itagira imipaka. Kurugero, igiciro cyacyo kiri hejuru ugereranije nicyuma gisanzwe gishyushya ibyuma, kandi kubera ibiranga ibikoresho byubutaka, bakeneye kwirinda kugongana gukabije mugihe cyo kwishyiriraho no gukoresha kugirango birinde kwangirika. Ariko ku nganda zifite ibyangombwa byinshi byo gushyushya ubushyuhe, kwangirika kw ibidukikije, hamwe nubwiza bwibicuruzwa, ituze, imikorere, nigihe kirekire cyo kubaho bizana akenshi byishyura ibyo bitagenda neza.
Muri iki gihe, hamwe n’iterambere ry’inganda zikora inganda zigana ku buryo bunoze kandi buhanitse, ibisabwa ku bikoresho byo gushyushya nabyo bigenda byiyongera. Nkikintu cyiza cyo gushyushya inganda, imiyoboro ya radiyo ya silicon karbide igenda igira uruhare runini mubice nka ceramika, metallurgie, na electronics. Ntishobora kuba ijisho ryiza nka tekinoroji igenda itera imbere, ariko mubyukuri iyi mico yo "kwumira kumyanya yayo" bucece mubidukikije bikabije bigatuma iba "impuguke irwanya ubushyuhe bwo hejuru" mubikorwa byinganda, itanga ingwate zizewe muburyo butandukanye bwo gushyushya ibintu.
