Urupapuro rwa Graphite rujana umuyagankuba

Ishingiro ry'igicuruzwa

Igipande c’umuyagankuba gishobora gutwara umuyagankuba ni igikoresho gikora cane gifatanya ubushobozi bwo gutwara umuyagankuba neza n’uguhinduranya. Igizwe n’ivyuma vy’agaciro kanini/vy’ubuhinga nk’ibikoresho vya mbere, biciye mu gutera ivyatsi mu bushuhe bwinshi, gutera ivyatsi, no gucapura neza. Agaciro kayo nyamukuru kari mu gutorera umuti ububabare bw’ibikoresho vya kera bikomeye bishobora gutwara umuyagankuba (nk’ibipande vy’umuringa n’ibipande vy’aluminium) - ingorane zo kwifatanya n’ibintu bitameze neza, ukuntu bishobora guca, n’uburemere mu bikoresho bifise uburemere buke. Ishobora gushika ku gutanga umuriro ushikamye no gukuraho ubushuhe bwo gufasha mu bihe vy’ugukoresha bike, bigoramye, canke bikomeye, kandi ikora nk’ikintu nyamukuru co gufasha mu guhuza amashanyarazi kwizigirwa cane mu bikoresho vy’ubuhinga bwa none no mu bikorwa bishasha vy’inguvu.

2.Ivyagezwe vy'ubuhinga

3.Ibirango nyamukuru

(1) Uburyo bwiza cane bwo kuyobora umuyagankuba

Igikoresho co guhangana n’umuringa ni 10-50 μΩ·cm (kigeragejwe ku 25 degrees na 5 MPa), kandi ubushobozi bwaco bwo gutwara umuriro buri hafi y’ibice 80% vy’igipande c’umuringa (1.72 μΩ·cm), mu gihe kirinda ibibazo vy’uguhinduka kw’ivyuma n’ugusenyuka kw’ibikoresho vy’ivyuma. Uguhuza kw’ugusangira kw’amashanyarazi mu ndege ni Kurenga canke kungana na 95%, bishobora kugabanya neza ivyiyumviro vy’amashanyarazi yo mu karere no gukingira ibihimba vy’umubiri gusha.

(2)Uguhinduranya neza cane no guhuza n'ivyo

Ku bipande bifise uburebure buri munsi canke bungana na 0,2 mm, umurongo mutoyi wo gupfukama ushobora gushika kuri 5-10 mm, kandi gupfukama gusubiramwo ntibizotuma bimenagurika canke ngo bisenyuke. Ishobora kwifatanya cane n’ibintu bitameze neza (nk’imirongo y’ingingo n’imibumbe y’ibipapuro vy’ibipande) no kwuzuza ibice bitobito ( Biri munsi canke bingana na 0,1 mm), bikaba bituma umuyagankuba ubandanya gukorana no mu bidukikije binyiganyiga.

(3)Ibikorwa bibiri vy'ugutwara n'ugukwiragira kw'ubushuhe

Mu gihe itwara umuyagankuba, irafise ubushobozi bwo gutwara ubushuhe mu ndege bugera kuri 150-400 W/(m·K), bushobora gutuma ubushuhe buva ku bihimba vy’umuyagankuba (nk’ibice vy’umuyagankuba n’amabateri) buja mu bice bitanga ubushuhe. Ugereranije n’ibikoresho bishobora gutwara umuyagankuba bikora kimwe, birashobora kugabanya igitigiri c’ibikoresho biri imbere muri ico gikoresho n’ibice birenga 30 kw’ijana, bikaba bizigama umwanya wo mu mutima.

(4)Ugushobora guhindura ibidukikije

Ubushuhe bukoreshwa ni -60~200℃, kandi burashobora kuguma bufise ubushobozi bwo gutwara umuyagankuba (uguhinduka kw’ubushobozi bwo guhangana n’umuyagankuba Buri munsi canke bungana na 10%) mu bidukikije bifise ubushuhe bwinshi-, ubushuhe buke, canke bifise ubukonje (30%-95% ubukonje buringaniye ku 40% ). Irashobora guhangana n’aside n’amazi bigoyagoya (pH 4-9) kandi ntikorana n’ibikoresho bisanzwe vyo gupfunyika ibintu (nk’ivyuma vy’ivyuma bita epoxy na silicone).

(5)Ibidukikije & Biroroshe Gukora

Amabara ya graphite ashobora gutwara umuriro akozwe mu graphite y’ubusuku bwinshi-ifise ubusuku burenga 99,9%, ata vyuma bikomeye nk’ivyuma vy’amabuye y’agaciro, mercury, cadmium, n’ibindi, kandi yubahiriza ingingo ngenderwako z’ibidukikije za RoHS 2.0 na REACH. Ishobora guhindurwa mu buryo butandukanye nk’ibipande, umurongo, ibice bicitse, n’ibindi biciye mu gucapura n’ugutera ibimenyetso bikoresheje laser, n’ubuhinga bwo gucapura ± 0.05 mm.

(1)Igikoresho c'abaguzi c'ubuhinga bwa elegitoronike

Ishobora gukoreshwa mu guhuza umuriro imbere muri telefone ngendanwa (nk’ibiri hagati y’ibipimo vya LCD n’ibipande vy’amabara y’umuyagankuba), amabara y’umuyagankuba y’amabateri ya laptop, n’ibipfukisho vy’umuyagankuba (EMI) vy’amatelefone y’amatwi ata nsinga. Ishingiye ku bimenyetso vyayo bishobora guhinduka, bifise uburemere buke be n’ibikorwa bibiri vyo gutwara ubushuhe n’ugukuraho ubushuhe, irahuza n’imiterere y’imbere y’ibikoresho ikomeye kandi idasanzwe, mu gihe ishobora gushitsa ivyo bikenewe mu gukuraho ubushuhe no gufatanya n’umuyagankuba.

(2)Umurima mushasha w'inguvu za bateri

Ibereye ku bateri ya litiyumu-ion PACK ibikoresho bikoranya amashanyarazi (nk’amabateri y’amashanyarazi y’ibinyabiziga bikoresha umuyagankuba), amabara y’amashanyarazi angana y’amashanyarazi y’ibice vy’amabateri, n’ibipfukisho vy’amashanyarazi hagati y’ibice vy’amabateri n’Ivyuma vyo Gucungera Amabateri (BMS). Kubera ko ifise ubushobozi bwo gutwara umuyagankuba, ishobora guhangana n’ubushuhe, kandi ikaba ishobora guhuza n’ibindi, ituma umuriro ugenda neza mu gihe co gucapura no gukuraho umuriro, irashobora kwihanganira uguhinduka kw’ubushuhe bwo gukora, kandi igashobora guhura n’ibibanza bidasanzwe vyo gushiramwo ibikoresho.

(3)Inganda z'ubuhinga bwa elegitoronike

Ishobora gukoreshwa nk’ibikoresho bijana umuriro ku bikoresho vy’inganda (nk’ibikoresho bipima umuvuduko n’ubushuhe), ibikoresho bifatanya umuriro ku bikoresho vy’inganda bishobora guhinduka, n’ibikoresho vyo gushiramwo umuriro ku bikoresho bigenzura inganda. Kubera ko ifise ubushobozi bwo gutwara umuyagankuba buhamye kandi igashobora guhindura neza ibidukikije, igumya amasano yizigirwa y’umuyagankuba mu bidukikije bikomeye (nk’uguhinduka kw’ubushuhe n’ugusenyuka gutoyi), igashitsa ibisabwa mu gutanga ikimenyetso c’ibimenyetso, gutwara umuyagankuba mu nzira, no gushiramwo ibikoresho hasi.

(4)Igikoresho c'ubuhinga bwa elegitoronike c'imodoka

Ibereye ku bikoresho bijana umuyagankuba mu bikoresho vy'imyidagaduro vyo mu modoka, amasahani y'umuyagankuba y'amatara y'imodoka, n'amahuza y'umuyagankuba ku bikoresho vyo gushaja biri ku -umuduga. Ubushobozi bwayo bwo guhangana n’ubushuhe bwinshi-bushobora kwihanganira ukuduga kw’ubushuhe bw’ibihimba, kandi ubushobozi bwayo bwo kurwanya-uguhungabana burahuye n’ibidukikije bihinduka vy’ibinyabiziga, bikaba bituma haba uguhuza kw’amashanyarazi gukomeza kandi gukomeye.
