Precision-Machined Graphite Plate ni igikoresho ca graphite gikozwe biciye mu gukora neza cane, gifise ukwihanganira gukomeye kw’ingero, guheza neza ku ruhande n’imiterere y’ubuhinga igoye. Ihuza ubushobozi bwiza cane bwa graphite n’ubuhinga bwo gukora neza, kandi ikoreshwa cane mu bikorwa vy’inganda vy’ubuhinga bwinshi.
Ubuhinga nyamukuru bwo gukoresha
1. Inganda y'ibice vy'umuyagankuba/pv
- Gukora ama wafer: igikombe co kunyonga c’umuyagankuba, ibihimba vy’ifuru y’ugukwiragiza, isahani itwara CVD.
- Ivyuma bikoreshwa n’umuyagankuba: ubwato bwa graphite bwa PECVD, igikoresho co gutera ivyatsi.
- Igishushanyo c’amatara: Igishushanyo c’ibara ry’agahama ca MOCVD.
2. Gutunganya umuco w'ama electron -- ibikoresho vy'ama electrode: graphite y'ubusuku bwinshi, ikoreshwa mu gutunganya neza ibibumbano.
3. Ifuru y'inganda/ibikoresho vy'ubushuhe bwinshi -- ibikoresho vy'ubushuhe bw'ifuru y'ikibiriti kimwe, ivyuma vy'ibara ry'agahama vy'ifuru y'ubushuhe, inzira y'uburongozi.
4. Igikoresho c'amavuta/inguvu nshasha -- Igikoresho c'amavuta gifise amabara abiri, igikoresho co gutera amavuta y'ibinyabiziga.
5. Ibikoresho/ubushakashatsi vy’ukuri -- Inkinzo y’amabuye y’agaciro yo gupfuka amaso, ikibanza c’akarorero c’imishwarara ya X, ibihimba vy’imibumbe bishobora guhangana n’ubushuhe bwinshi vy’ikirere.

Ibirango vy'umubiri n'ivy'imiti
- Ubushobozi bwo gutwara umuyagankuba: Amabara y’amabuye y’agaciro yerekana ubushobozi budasanzwe bwo gutwara umuyagankuba, ahanini bivuye ku miterere yayo ihamye π-π y’imirongo ikozwe n’ibicu vy’ama elegitoroni π n’imigenderanire y’amabuye y’agaciro yitwa carbone-carbon covalent. Ivyo bituma ama elegitoroni ashobora gutwara neza mu kintu, ivyo bikaba bituma habaho ubushobozi bwo guhangana n’ibintu buke cane bugera kuri 10^-6 Ω·m. Ku bw’ivyo, graphite ikora nk’ikintu ciza cane co gukoresha mu gukoresha amashanyarazi.
- Ubushuhe: Igipande ca graphite na co nyene gifise ubushobozi bwiza cane bwo gutwara ubushuhe, ubushuhe bwaco burarengeye ivyuma, ivyuma, amabuye y’agaciro n’ibindi bikoresho vy’ivyuma. Ivyo biva ku mibumbe y’ibipande n’imiterere y’amabuye y’agaciro itegekanijwe cane, ku buryo inguvu z’ubushuhe zishobora guca neza biciye mu guhungabana hagati y’ibipande.
- Ivyiza vy’ubuhinga: Igipande ca graphite gifise inkomezi nyinshi, gishobora guhinduka cane kandi ntikishobora gutabuka. Igikoresho cayo ca Young n’inkomezi zaco zishobora gushika kuri 1 TPa na 130 GPa, ivyo bikaba ari incuro zirenga amajana z’ivyuma. Ivyo bikomeye cane bituma isahani ya graphite igira ugushikama kwiza cane mu bidukikije vy’umuvuduko mwinshi n’ubushuhe bwinshi.
- Ugushikama kw’imiti: Igihuzu ca carbone-carbone c’isahani ya graphite gifise inguvu nyinshi z’ubucuti n’ubushobozi buke bwo gusubirana n’imiti, kandi gifise ubushobozi bwo guhangana n’imiti myinshi. Asidi nkeyi gusa n’ibindi bihimba vy’umubiri bishobora kuyiboza, ni co gituma isahani ya graphite ikoreshwa cane mu bikoresho vy’ubuhinga bwa shimi no mu bikoresho vy’ubuhinga bwa catalyseur.
Precision-Machined Graphite Plate yacitse ikintu gihambaye mu guhingura ibintu vy’agaciro kanini kubera ukuntu ikora neza cane, idashobora guhangana n’ibidukikije cane be n’uko ishobora guhindura ibintu bikomeye. Kugira ngo umuntu ashobore gukora neza, ubusuku bwa graphite, ubunini bw’ibice, uburyo bwo kuyikora n’ukuntu ikoreshwa ku ruhande bikwiye kwitwararikwa neza igihe umuntu ahitamwo graphite.
