Inzuzi z'umuriro za silicon carbide (SiC)
Mu gihe cy'ubushyuhe bwinshi aho kugenzura amazi, kurwanya isuri, no kudahungabana k'ubushyuhe ari ingenzi,imiyoboro ya silikoni karubide (SiC)Bigaragara nk'igitangaza cy'ubuhanga. Bitandukanye n'imiyoboro isanzwe ya ceramic cyangwa iy'icyuma, imiterere yihariye ya SiC ikemura ibibazo mu buryo bwo gutwika, gutwara ibintu, no gutera imiti mu nganda. Iyi nkuru irasuzuma impamvu inganda zigenda zikoresha imiyoboro ya SiC kugira ngo zihindure imikorere yazo mu bikorwa bigoye cyane.
1. Yakozwe mu rwego rwo kurwanya ibidukikije biremereye cyane
Utuzu twa SiC ni abahanga mu gucunga umuvuduko mwinshi, amazi n'imyuka bishyuha cyane:
（1）Ubudahangarwa bw'isuri: Ihanganira uduce duto two mu injectors z'amakara, sisitemu zo guturitsa umucanga, cyangwa rocket propellants zidahinduka bitewe n'ubusaza.
（2）Kurokoka kw'ihindagurika ry'ubushyuhe: Igenda vuba hagati y'ubushyuhe bukabije (urugero: gutera lisansi mu itanura rya metallurgike) idacikagurika, bitewe n'ubushyuhe buke bwa SiC.
（3）Ubudahangarwa bwa Chimique: Irwanya ingese iterwa na aside/alkaline sprays, imyunyu yashongeshejwe, cyangwa umuriro ugabanya ogisijeni, bigatuma habaho imiterere ihamye y'urumuri.
2. Kugenzura neza inzira z'ingenzi zikoreshwa mu bikorwa by'ingenzi
Mu bikorwa bisaba ubuhanga bwa micron, imiyoboro ya SiC itanga icyizere ntagereranywa:
（1）Igenamiterere ry’amazi rihamye: Gukomeza umuvuduko uhamye w’amazi no kuyatera ndetse no nyuma yo kumara igihe kinini ugera ahantu hashyushye cyane mu bushyuhe bwa 1500°C+, bitandukanye n’ibyuma bihindagurika cyangwa ibyatsi bibikwa.
（2）Kugabanuka kw'ingufu: Irangi ryoroshye cyane rigabanya ubwinshi bw'ibikoresho mu byuma bitera lisansi cyangwa mu buryo bwo gutera imiti.
（3）Kwihanganira umuvuduko mwinshi: Ihangana n'umuvuduko wa hydraulic urenze 500 MPa, ikaba ari nziza cyane mu gukata amazi cyangwa mu kirere.
3. Gutuma umuriro ushya neza cyane
Utuzu twa SiC ni ingenzi cyane mu kunoza uburyo bwo gutwika bukoresha ingufu nyinshi:
（1）Guhagarara k'umuriro: Igishushanyo mbonera kidashyuha gituma habaho kuvanga lisansi n'umwuka mu byuma bikoresha gaze cyangwa mu byuma bitwika gazi, bigagabanya ahantu hashyuha cyane n'ibyuka bihumanya bya NOx.
（2）Guhindagurika kw'ibikomoka kuri peteroli: Bihuye na hydrogen, biofuel, cyangwa peteroli nini, bifasha ihinduka ry'isoko ry'ingufu zirambye.
（3）Ubushyuhe Buhagije: Gabanya ubushyuhe butakaza inkuta bitewe n'ubushyuhe bwinshi bwa SiC, wongere ubushobozi bwo gutwika kugeza kuri 15%.
Shandong Zhongpeng Special Ceramics Co., Ltd ni imwe mu mashami manini ya silicon carbide ceramic mu Bushinwa. SiC technical ceramic: Ubukana bwa Moh ni 9 (Ubukana bwa Moh bushya ni 13), bufite ubudahangarwa bwiza bwo kwangirika no kwangirika, ubukana bwiza bwo kwangirika no kurwanya oxidation. Igihe cy'akazi k'ibicuruzwa bya SiC ni inshuro 4 kugeza kuri 5 ugereranyije n'ibikoresho bya alumina 92%. MOR ya RBSiC ikubye inshuro 5 kugeza kuri 7 ugereranyije na SNBSC, ishobora gukoreshwa mu miterere igoye cyane. Uburyo bwo gutanga ibiciro ni bwihuse, gutanga ibintu ni uko byasezeranijwe kandi ubwiza ni ubwa mbere. Buri gihe dukomeza guhangana n'intego zacu kandi tugasubiza imitima yacu kuri sosiyete.
