Sisitemu zo Gushyigikira Ikiyiko cya Silicon Carbide Beam yo Guhindura Ubunini

Sisitemu zo Gushyigikira Ikiyiko cya Silicon Carbide Ishusho yagaragaye

Ibisobanuro bigufi:

Imirasire ya silicon carbide (SiC) ni ibikoresho by’ingenzi bya ceramic bikozwe mu bikoresho by’ibanze bya silicon carbide bifite isuku nyinshi binyuze mu guhuza ibintu, gutwika nta muvuduko, cyangwa kongera gukoresha crystallization. Bizwiho imbaraga zidasanzwe mu bushyuhe bwinshi, kurwanya oxidation, no kurwanya ubushyuhe, imirasire ya SiC yabaye ibintu by’ingenzi bitwara imizigo mu itanura rigezweho ry’inganda n’ibikoresho bitunganya ubushyuhe.

Ohereza imeri kuri twe

Ibiranga

Ishusho irambuye

Incamake y'ibicuruzwa

Mu itanura risanzwe, imitako ikunze gukorwa mu matafari adafite ingufu cyangwa ibikoresho bishingiye kuri alumina. Nubwo bihendutse, iyo mitako irahinduka byoroshye iyo ubushyuhe bwinshi bukabije, irangirika vuba mu mbaraga, kandi ikagira igihe gito cyo kuyikoresha. Mu buryo bunyuranye, imitako ya SiC ishobora gukora buri gihe kuri 1380°C–1650°C mu gihe ikomeza kugira imiterere myiza ya mekanike. Igihe cyo kuyikoresha kiba kirekire inshuro 5–10 ugereranyije n’igihe cyo kuyikoresha, bigabanura cyane ikiguzi cyo kuyisana, igihe cyo kuyikoresha, n’amafaranga yose ikoresha mu kuyikoresha.

Ibyiza by'ingenzi mu mikorere

Ubudahangarwa bw'ubushyuhe bwinshi

Ishobora gukora igihe kirekire hejuru ya 1380°C, hamwe n'ibikoresho bya SiC byateye imbere byihanganira ubushyuhe bwa 1650°C.
Igumana imiterere myiza mu gihe cy'ubushyuhe bwinshi, cyane cyane ikoreshwa mu gukora mu matanura manini no mu matanura azunguruka.

Imiterere myiza ya mekanike

Ingufu zisanzwe zo guhindagurika kw'ingufu: 250–350 MPa, inshuro nyinshi kurusha imirasire isanzwe yo guhindagurika kw'ingufu.
Ubukana bwinshi (Mohs ~ 9.0) butuma idapfa kwangirika cyangwa guhindagurika igihe kirekire.
Ubudahangarwa bwiza bwo gukurura umuyaga burinda kugwa cyangwa kugwa mu gihe cy'igihe kirekire.

Ubudahangarwa budasanzwe bw'ihungabana ry'ubushyuhe

Ihangana n'ibihe by'ubushyuhe n'ubukonje byihuse idacikagurika.
Ihangana n'ihindagurika ry'ubushyuhe rirenze 1000°C, ikaba ari nziza ku matanura ashobora guhagarara kenshi.

Kurwanya Oxidation no Kurwanya Ingese

Irwanya ikirere gifite aside na alkaline, ndetse n'ibidukikije bigabanya ogisijeni.
Iyo ubushyuhe buri hejuru, ubuso bwa SiC bukora urwego runini rwo kurinda SiO₂, rurinda neza ogisijeni.

Yoroheje kandi Irinda Ingufu

Ubucucike buri hagati ya 2.6–3.1 g/cm³, bworoheje kurusha icyuma, bigabanya umutwaro w'itanura.
Uburyo bwiza bwo gutwara ubushyuhe butuma ubushyuhe burushaho gukoreshwa neza, bugabanya ikoreshwa rya lisansi, kandi bugatuma ibicuruzwa bishya bikwirakwira kimwe.

Igihe kirekire cyo gukora

Igihe gisanzwe cyo gukora: imyaka 3–5 cyangwa irenga, ugereranije n’amezi 6–12 gusa ku mirasire isanzwe ihindagurika.
Kugabanuka kw'inshuro zo gusimbuza bigabanya igihe cyo kuruhuka no kubungabunga, bikongera umusaruro.

Imiterere n'Ibisobanuro by'Ibicuruzwa

Imirasire ya SiC yakozwe mu buryo butandukanye kugira ngo ihuze n'imiterere itandukanye y'itanura n'ibisabwa mu mikorere:

Imiringa y'Inkoni Zizengurutse: Ingano y'umurambararo Φ30–Φ80 mm; ikwiriye amatanura yoroheje n'ibikoresho bito byo gutwara imizigo.
Imitako y'impande ikomeye: Ibice bifatanye biri hagati ya mm 30 × 30 - mm 100 × 100; ni byiza cyane ku mitwaro iremereye n'uburebure burebure.
Ibara ry'urubura / I-Beams: Yoroheje kandi ifite igipimo cyiza cyo gukomera hagati y’uburemere; ikoreshwa cyane mu matanura manini yo mu miyoboro no mu matanura azunguruka.
Imitako ifite ishusho yihariye: Bikozwe hakurikijwe ibishushanyo by'abakiriya n'imiterere y'itanura kugira ngo bihuzwe neza cyane.

Uburebure Busanzwe: 500 mm – 4500 mm (ingano ndende ziraboneka iyo ubisabye).

Ahantu ho Gusaba

1. Inganda zikora ibirahuri

Imitako ya silicon carbide (SiC) ikoreshwa cyane mu matanura akorwamo ceramic, cyane cyane mugutwara imizigo, inkunga, no kohereza ubushyuhe.

Ibikoresho bya keramike bikoreshwa buri munsi: amasahani, ibikombe, n'ibindi bikoresho byo mu rugo mu mashyiga yo mu tunnel no mu mashyiga yo mu bwoko bwa roller.
Ibikoresho by'isuku: ubwiherero, amabasi yo gukaraba, n'ibindi bikoresho binini bisaba ubushobozi bukomeye bwo gutwara imizigo mu gihe cyo gutwika mu bushyuhe bwinshi igihe kirekire.
Ibumba ry'inyubako: amatafari yo hasi, amatafari yo ku nkuta, n'amatafari manini ya ceramic, aho imitako ya SiC ishyigikira neza kandi igashyushya kimwe.
Ibikoresho by'ikoranabuhanga/by'imiterere: nk'ibumba rya alumina cyangwa silikoni nitride, rikenera ubushyuhe bwinshi cyane bwo kurasa n'ingendo ndende, bigatuma igihe kirekire cy'imirasire ya SiC kiba ingenzi.

2. Inganda z'ibirahuri

Amatanura yo gukurura ikirahure: inyubako zishyigikira amacupa, ibikoresho by'ibirahure, n'ibirahure birambuye mu gihe cyo gupfunyika.
Gutwika ikirahure: mu gukora ikirahuri cyihariye (ikirahuri cy’amatara, ikirahuri cyo kwerekana, nibindi), imirasire ya SiC igenzura ko ubushyuhe buhamye kandi bukwirakwira mu buryo bumwe.

Ibyiza: kudahinduka, gushyuha vuba, no kugabanuka kw'inenge mu bicuruzwa biterwa n'umuvuduko utaringaniye.

3. Inganda zikora ibyuma n'ifu

Gutunganya ibyuma biva mu ifu: ibice by'imiterere bikozwe mu cyuma, icyuma kidashonga, n'ibindi bikomoka ku byuma.
Ibikoresho bya rukuruzi: magnets za ferrite, zikoresha ubushyuhe bwa 1200–1400°C, zisaba imirasire ifite ubushobozi bwo guhangana n'ubushyuhe kandi imara igihe kirekire.
Ibikoresho by'ubutaka bidasanzwe: gukaranga okiside cyangwa karuboneti, akenshi mu kirere cy’itanura rigoye.

SiC beams excelmu kurwanya ogisijeni n'ingufu, bigatuma biba byiza ahantu hakomeye hakorerwa ibyuma.

4. Ibikoresho bya shimi n'ingufu nshya

Kalisiyumu ya Katalisiti: zeolite, utuyunguruzo twa molekile, na katalysts za peteroli zikoreshwa mu itanura ry’ibinyabutabire rishyushye cyane.
Ibikoresho bishya by'ingufu:
- Ibikoresho bya cathode bya bateri ya Lithium (NCM, LFP).
- Ingufu za hydrogène n'ibikoresho bya lisansi bikoreshwa mu gutwika.

Ibyiza: kugabanuka kw'ikoreshwa ry'ingufu, igihe kirekire cyo gukora, no kunoza imiterere y'ibicuruzwa.
