'Ubwugarizi burwanya kwambara' bwihishe mu bikoresho by'inganda: Ubwugarizi burwanya kwambara bwa Silicon Carbide

Ku murongo w’umusaruro w’uruganda, hari ibikoresho bimwe na bimwe “bitwara imizigo iremereye” – nk’imiyoboro yo gutwara amabuye y’agaciro n’ibigega byo kuvanga ibikoresho, bigomba gukorana n’uduce twihuta cyane n’ibikoresho bikomeye buri munsi. Ibi bikoresho bimeze nk’amabuye mato menshi asya, asya ku nkuta z’imbere z’ibikoresho umunsi ku wundi. Uko igihe kigenda gihita, ibikoresho bizasenywa bikaba “ibikomere”, bidasaba gufungwa kenshi kugira ngo bikomeze gusanwa, ahubwo bishobora no kugira ingaruka ku muvuduko w’umusaruro.umwenda urinda kwangirika kwa karubide ya silikonini "ingabo irinda" y'inganda yagenewe gukemura iki kibazo cy'"imyambarire".
Hari abantu bashobora kuba bashaka kumenya bati, “silicon carbide” ni iki mu by’ukuri? Mu by’ukuri, ni ibikoresho bidakora byakozwe mu buryo bw’ubukorano bisa n’icyuma gikomeye cy’umukara wijimye kandi gisa n’amabuye asanzwe, kikaba icya kabiri nyuma ya diyama mu gukomera. Mu magambo make, iyo ukoresheje iki gikoresho gikomeye ukagihindura ishusho ikwiriye urukuta rw’imbere rw’ibikoresho, nk’impapuro cyangwa blok, hanyuma ukagishyira ahantu horoshye kwangirika, kiba nk’icyuma kidashira cya silicon carbide. Imikorere yacyo ni iy’ukuri cyane: “kibuza” kwangana no gukururana kw’ibikoresho, kimwe no gushyira urwego rw’ “intwaro idashira” ku rukuta rw’imbere rw’ibikoresho.
Nk'"inzobere mu nganda idashira" mu nganda, icyuma gikozwe muri silicon carbide gifite ibyiza bibiri bifatika. Kimwe ni uko gikomeza kwangirika. Kubera ko gihura n'ihindagurika ry'ibikoresho bikomeye nk'amakara, amabuye y'agaciro, n'umucanga wa quartz igihe kirekire, ubuso bwacyo buragoye gushwanyaguza cyangwa gukuraho, bigatuma kidashira cyane kurusha icyuma gisanzwe n'ibikoresho bisanzwe bya ceramic. Icya kabiri ni ukwimenyereza ibidukikije bikomeye. Mu bihe bimwe na bimwe by'umusaruro, ibikoresho ntibisya gusa ahubwo binatwara ubushyuhe bwinshi (nk'ubwo mu nganda zishongesha) cyangwa kwangirika (nk'uko bimeze mu nganda zikora imiti). Ibikoresho bisanzwe bidashira bishobora "kwangirika" vuba, ariko icyuma gikozwe muri silicon carbide gishobora kugumana ubusugire muri bene ibyo bidukikije, bigatuma bigorana kwangirika bitewe n'ubushyuhe bwinshi no kwangirika bitewe n'ibikoresho bya aside na alkaline.

Ariko, kugira ngo iki gikoresho kidashira kigire akamaro, uburyo bwo kugishyiraho ni ingenzi cyane. Kigomba guhindurwa hakurikijwe ingano n'imiterere y'ibikoresho, hanyuma kigashyirwa ku rukuta rw'imbere rw'ibikoresho mu buryo bw'umwuga kugira ngo gihuze neza hagati yabyo byombi - niba hari icyuho, ibikoresho bishobora "kwinjira" no kwangiza umubiri w'ibikoresho. Nubwo ishoramari rya mbere mu gikoresho cya silikoni carbide riri hejuru y'iry'icyuma gisanzwe, mu gihe kirekire, bishobora kugabanya cyane inshuro zo kubungabunga no gusimbuza ibikoresho, ahubwo bigafasha ibigo kuzigama amafaranga menshi.
Muri iki gihe, mu nganda zishaje cyane nko mu bucukuzi bw'amabuye y'agaciro, amashanyarazi, n'ibikoresho by'ubwubatsi, icyuma kidashaje cya silikoni cyabaye "amahitamo" ku bigo byinshi. Ntabwo kigaragara cyane, ariko kirinda bucece imikorere ihamye y'ibikoresho bishya hamwe n'"ubukomere" bwacyo, bigatuma ibyo bikoresho byoroshye gusaza "bikora" igihe kirekire - iyi ni yo gaciro kacyo nk'"umurinzi udashaje" w'inganda.
