Molybdenum isanzwe ikoreshwa muburyo bwubushyuhe bwo hejuru kubera igiciro cyayo giciriritse, ikwirakwizwa rito muri kirisiti ya silicon, hamwe na coeffisente yo gutandukanya cyane ya 5 × 108, ituma umubare munini wa molybdenum wanduye mbere yo gusenya imiterere ya kristu.
2. Ibikoresho byo kubika ubushyuhe
Ibikoresho bikunze gukoreshwa cyane ni karubone yunvikana muburyo butandukanye. Carbone yumva ikozwe muri fibre yoroheje, ikora nka insulasiyo kuko ihagarika imirasire yumuriro inshuro nyinshi mugihe gito. Carbone yoroshye yunvikana mubipapuro bito cyane, hanyuma bigacibwa muburyo bwifuzwa hanyuma bikagoramika cyane kuri radiyo yumvikana. Felts ikize igizwe nibikoresho bisa na fibre, kandi bingo irimo karubone ikoreshwa muguhuza fibre yatatanye mubintu bikomeye kandi bifite ishusho. Gukoresha imyuka ihumeka ya karubone aho kuba binder irashobora kunoza imiterere yibikoresho.
Ubusanzwe, ubuso bwinyuma bwumuriro wumuriro ukiza wasizwe hamwe na grafitike ikomeza cyangwa ifu kugirango igabanye isuri no kwambara kimwe no kwanduza uduce. Ubundi bwoko bwibikoresho bishingiye kuri karubone nabyo birahari, nka karuboni ifuro. Muri rusange, ibikoresho bishushanyije biragaragara ko bikunzwe kuko gushushanya bigabanya cyane ubuso bwa fibre. Gusohora kw'ibi bikoresho byo hejuru-by'ubutaka biragabanuka cyane, kandi bisaba igihe gito cyo kuvoma itanura mu cyuho gikwiye. Ikindi ni C / C yibikoresho, bifite ibimenyetso byingenzi nkuburemere bworoshye, kwihanganira kwangirika kwinshi nimbaraga nyinshi. Byakoreshejwe mumashanyarazi kugirango bisimbuze ibice bya grafite bigabanya cyane inshuro zo gusimbuza ibice bya grafite, bizamura ubwiza bwa monocrystalline nubuhinzi butajegajega.
Ukurikije ibikoresho fatizo byashyizwe ahagaragara, ibyuka bya karubone bishobora kugabanywamo ibice bya karuboni ishingiye kuri polyacrylonitrile, ibyuka bya karuboni bishingiye kuri viscose, hamwe na karuboni ishingiye kuri pisine.
Polyacrylonitrile ishingiye kuri karubone yumva ifite ivu rinini. Nyuma yo kuvura ubushyuhe bwo hejuru, fibre imwe iba yoroheje. Mugihe cyo gukora, biroroshye kubyara umukungugu kugirango uhumanye ibidukikije. Muri icyo gihe, fibre irashobora kwinjira byoroshye mu myobo no mu myanya y'ubuhumekero y'umubiri w'umuntu, bikaba byangiza ubuzima bw'abantu. Viscose ishingiye kuri karubone yumva ifite imikorere myiza yubushyuhe. Nibyoroshye byoroshye nyuma yo kuvura ubushyuhe kandi ntabwo byoroshye kubyara umukungugu. Nyamara, igice cyambukiranya fibre mbisi ishingiye kuri viscose ntisanzwe, kandi hariho ibinono byinshi hejuru ya fibre. Biroroshye kubyara imyuka nka C02 munsi yikirere cya okiside yumuriro wa silicon CZ, bigatuma imvura igwa ogisijeni nibintu bya karubone mubintu bya silikoni ya monocrystalline. Inganda nyamukuru zirimo Ubudage SGL nandi masosiyete. Kugeza ubu, inganda zikoreshwa cyane mu nganda zikoresha monocrystalline ni karuboni ishingiye ku cyuma, ikaba ifite imikorere mibi yo gukwirakwiza amashyanyarazi kurusha karuboni ishingiye kuri viscose, ariko karuboni ishingiye ku kibanza yumva ifite isuku nyinshi kandi ihumanya umukungugu muke. Ababikora barimo Ubuyapani bwa Kureha Chemical na Osaka Gazi.
Kuberako imiterere ya karubone yunvikana idakosowe, ntibyoroshye gukora. Ubu ibigo byinshi byateguye ibikoresho bishya byubushyuhe bushingiye kumyuka ya karubone yakize. Carbone yakize yunvikana, nanone yitwa ibyuma bikomeye, ni karubone yunvikana ifite imiterere runaka hamwe numutungo wokwitunga nyuma yumutima woroshye winjijwe hamwe na resin, laminated, cured na carbone.
Ubwiyongere bw'ubwiyongere bwa silikoni ya monocrystalline bugira ingaruka ku buryo butaziguye ku bushyuhe bw'ubushyuhe, kandi ibikoresho bya karuboni fibre itanga ubushyuhe bigira uruhare runini muri ibi bidukikije. Carbone fibre yamashanyarazi yoroheje yunvikana iracyafite inyungu zikomeye mumashanyarazi ya semiconductor yinganda kubera inyungu zayo, ingaruka nziza zokoresha ubushyuhe bwumuriro, igishushanyo cyoroshye nuburyo bwihariye. Byongeye kandi, karuboni fibre ikomeye yubushyuhe bukabije yumuriro izagira umwanya munini witerambere mumasoko yumuriro wumuriro bitewe nimbaraga zayo nubushobozi buhanitse. Twiyemeje gukora ubushakashatsi no kwiteza imbere mubijyanye nibikoresho byogukoresha ubushyuhe, kandi tugahora tunoza imikorere yibicuruzwa kugirango duteze imbere iterambere niterambere ryinganda zikoresha amashanyarazi.
