Umwambaro udashira wa silicon carbide: ingabo ikomeye yo gukoresha mu nganda

Mu bihe byinshi by’inganda, ibikoresho akenshi bigomba guhangana n’ahantu hatandukanye hagoye gukorera, kandi ibibazo byo kwangirika no gucika bigira ingaruka zikomeye ku buzima bw’ibikoresho ndetse n’imikorere myiza y’akazi. Kugaragara kw’umugozi udashobora kwangirika wa silicon carbide bitanga igisubizo cyiza kuri ibi bibazo, kandi buhoro buhoro bigenda bihinduka ingabo ikomeye y’ibikoresho by’inganda.
Karubide ya silikoni, igizwe na karuboni na silikoni, ifite imiterere itangaje. Ubukana bwayo buri hejuru cyane, ikaba iya kabiri nyuma ya diyama ikomeye cyane mu miterere yayo, kandi ubukana bwayo bwa Mohs ni ubwa kabiri nyuma ya diyama, bivuze ko ishobora kwihanganira gushwanyagurika no gucibwa kw'uduce duto dukomeye kandi igakora neza mu kudashwanyagurika. Muri icyo gihe, silikoni carbide ifite kandi coefficient nkeya yo gushwanyagurika, ishobora kugenzura igipimo cyo kwangirika ku rwego rwo hasi cyane mu bihe bigoye nko gushwanyagurika kwumye cyangwa amavuta make, bigatuma igihe cyo gukoresha ibikoresho kirushaho kuba gito.
Uretse ubukana n'ubushobozi buke bwo gukururana, imiterere ya silicon carbide nayo irahamye cyane, ifite ubushobozi bwo kudakora neza mu by'ubutabire. Ifite ubushobozi bwo kurwanya ingese ituruka kuri aside zikomeye (usibye aside hydrofluoric na aside fosforique ishyushye), ishingiro rikomeye, imyunyu yashongeshejwe, n'ibyuma bitandukanye byashongeshejwe (nka aluminiyumu, zinc, umuringa). Iyi miterere ituma ikora neza ndetse no mu bidukikije bikomeye aho ibintu byashongeshejwe n'ibyangiritse biba hamwe.
Urebye imiterere y'ubushyuhe n'imiterere y'umubiri, karubide ya silikoni nayo igaragaza imikorere myiza cyane. Ifite ubushobozi bwo gutwara ubushyuhe bwinshi kandi ishobora gusibanganya ubushyuhe buterwa no gukururana, yirinda ko ibintu byoroha cyangwa gucika kw'ubushyuhe biterwa no gushyuha cyane kw'ibikoresho, kandi igakomeza kugira ubushobozi bwo kwangirika neza; ingano yayo yo kwaguka k'ubushyuhe ni ntoya, ishobora kwemeza ko ibikoresho bihamye kandi ikagabanya kwangirika k'ubushyuhe ku bikoresho mu gihe cy'ihindagurika ry'ubushyuhe. Byongeye kandi, ubushyuhe bwinshi bwa karubide ya silikoni nabwo burakomeye, aho ubushyuhe bugera kuri 1350 ° C mu kirere (ibidukikije bigabanya ogisijeni) ndetse no hejuru mu bidukikije bitagira umwuka cyangwa bigabanya.

Hashingiwe ku miterere yavuzwe haruguru, imiyoboro irinda kwangirika kwa silicon carbide yakoreshejwe cyane mu nganda nyinshi. Mu nganda zitanga ingufu, imiyoboro ikoreshwa mu gutwara ibikoresho nk'ivu ry'umukungugu ikunze gutwarwa n'uduce duto tw'amashanyarazi twihuta cyane, kandi imiyoboro isanzwe y'ibikoresho irashira vuba. Ariko, nyuma yo gukoresha imiyoboro irinda kwangirika kwa silicon carbide, ubudahangarwa bw'imiyoboro burarushaho kuba bwiza, kandi igihe cyo kuyikoresha kirayongerekana cyane; Mu nganda zicukura amabuye y'agaciro, gushyiraho imiyoboro irinda kwangirika kwa silicon carbide ku bice birinda kwangirika nk'imiyoboro itwara ibintu n'imbere mu byuma bigabanya inshuro zo kubungabunga ibikoresho kandi bikanoza umusaruro; Mu nganda zikora imiti, zihanganye n'ibintu bihumanya n'ibidukikije bigoye, imiyoboro irinda kwangirika kwa silicon carbide ntabwo irinda kwangirika gusa, ahubwo inarwanya kwangirika kwa shimi, igenzura ko ibikoresho bikoresha neza kandi bihamye.
Muri make, umwenda urinda kwangirika kwa silicon carbide utanga uburinzi bwizewe ku bikoresho by’inganda kubera imikorere yawo myiza. Hamwe n’iterambere rihoraho ry’ubumenyi bw’ibikoresho, imikorere y’umwenda urinda kwangirika kwa silicon carbide izakomeza kunozwa, kandi ikiguzi gishobora kugabanuka cyane. Mu gihe kizaza, byitezwe ko uzakoreshwa mu nzego nyinshi kandi ukagira uruhare runini mu mikorere myiza kandi ihamye y’umusaruro w’inganda.
