Isesengura ry’Ibintu ku Kunoza Ingano y’Uburinganire bwa granite hejuru y’icyuma gishongeshejwe mu buryo bwo kugenzura ubwikorezi bw’imashini ikoresha bateri ya Lithium.

Ese?
Mu ikorwa rya bateri za lithium-ion, ikoreshwa rya coating, nk'ikintu cy'ingenzi, rigira ingaruka ku mikorere n'umutekano wa bateri. Gukomera kw'urwego rugenzura ingendo rw'imashini ikingira bateri ya lithium bigira uruhare runini mu gukoresha neza ikoreshwa rya coating. Granite n'icyuma gishongeshejwe, nk'ibikoresho bikunze gukoreshwa kuri platform, itandukaniro mu guhagarara kwabyo mu ngero ryakuruye abantu benshi. Iyi nkuru izasesengura byimbitse iterambere rikomeye mu guhagarara neza kw'ingero za granite ugereranije n'icyuma gishongeshejwe kuri platform igenzura ingendo y'imashini zikingira bateri ya lithium binyuze mu miterere y'ibikoresho, amakuru y'igerageza n'ingero z'ikoreshwa.
Imiterere y'ibikoresho ni yo igena ishingiro ry'ubudahangarwa
Ibyuma bicuzwe, nk'ibikoresho gakondo by'inganda, byakoreshejwe cyane mu bijyanye no kugenzura ingendo bitewe n'imikorere yabyo myiza yo gucuzwa ndetse n'inyungu z'ikiguzi. Ariko, ibikoresho bicuzwe bifite inenge. Imiterere yabyo y'imbere irimo ingano nini ya grafiti y'ibice, ingana n'imyanya y'imbere kandi izagabanya ubukana bw'ibikoresho muri rusange. Hagati aho, igipimo cyo kwaguka k'ubushyuhe bw'icyuma gicuzwe ni kinini, hafi 10-12 × 10⁻⁶/℃. Mu gihe ubushyuhe bwinshi buterwa n'imikorere y'igihe kirekire ya bateri ya lithium, bushobora kwangirika. Byongeye kandi, hari ubushyuhe bukabije mu cyuma gicuzwe. Uko igihe kigenda gihita, kurekurwa kw'ubushyuhe bizatera impinduka zidasubirwaho mu bunini bw'urukuta, bigira ingaruka ku buryo bwo gucuzwa neza.

Granite ni ibikoresho karemano byakozwe binyuze mu mikorere ya geologi mu myaka amagana na miliyoni. Imiterere yayo y'imbere ya kristu ni minini kandi ingana, kandi ifite ubusugire buhanitse. Igipimo cyo kwaguka kwa granite ni 0.5-8 × 10⁻⁶ / ℃ gusa, bingana na 1/2-1/3 cy'icyuma gishongeshejwe, kandi ntiyumva cyane impinduka z'ubushyuhe. Hagati aho, granite irakomeye mu miterere, ifite imbaraga zo gukanda kugeza kuri kilogarama 1.050-14.000 kuri santimetero kare. Ishobora kurwanya neza ingaruka z'ingufu zo hanze n'imitingito, itanga urufatiro rukomeye kandi ruhamye rw'urubuga rwo kugenzura ingendo. Nta kintu na kimwe gisigaye kirimo imbere, kandi ntabwo izatera impinduka mu ngero bitewe no kurekura ubusugire, bigatuma urwego rw'ibikoresho rudahinduka bitewe n'imiterere y'urutonde.
Amakuru y'igerageza yemeza itandukaniro ry'imikorere
Kugira ngo bagereranye itandukaniro riri hagati ya granite n'icyuma gikozwe mu buryo bw'incamake, itsinda ry'ubushakashatsi ryakoze igerageza ryihariye. Hatoranijwe urubuga rubiri rwo kugenzura ingendo rw'imashini ikora bateri ya lithium ifite imiterere imwe, ikozwe muri granite n'icyuma gikozwe mu buryo bw'incamake, kandi rwageragejwe mu bihe bimwe by'ibidukikije. Igerageza ryiganye imikorere nyayo y'imashini ikora bateri ya lithium. Mu gukoresha ibikoresho buri gihe, impinduka z'ingano y'uru rubuga mu bihe bitandukanye zakurikiranwe.
Ibisubizo by'igerageza bigaragaza ko nyuma y'amasaha 24 ahoraho, bitewe n'ubushyuhe buterwa n'imikorere y'ibikoresho, ubushyuhe bw'ubuso bw'urukuta rw'ibikoresho by'icyuma cyashongeshejwe bwiyongereyeho hafi 15°C, bituma uburebure bw'urukuta rwiyongereyeho 0.03mm. Mu bihe bimwe, ihindagurika ry'ingano y'urukuta rw'amabuye y'agaciro ni nk'aho rito cyane, kandi ingano yarwo iri munsi ya 0.005mm. Nyuma y'amasaha 1000 y'ibizamini byo gusaza igihe kirekire, bitewe no kurekura imbaraga z'imbere no kwiyongera k'ubushyuhe, ikosa ry'ubugari bw'urukuta rw'icyuma cyashongeshejwe ryariyongereye kuva kuri 0.01mm ya mbere kugera kuri 0.05mm. Ikosa ry'ubugari bw'urukuta rw'amabuye y'agaciro buri gihe riguma muri 0.015mm, kandi inyungu yo kudahinduka kw'ingano iragaragara.
Ibyagezweho bitangaje mu mikoreshereze y'ibintu mu buryo bufatika
Mu ikorwa ry’ikigo kinini gikora bateri za lithium, hari hakoreshwaga imbuga zo kugenzura imikorere y’icyuma gikozwe mu cyuma. Uko igihe cyo gukoresha ibikoresho cyagendaga cyiyongera, ubwiza bw’imyambaro yakoreshejwe bwagiye bugabanuka buhoro buhoro, bituma ubugari bw’imbuga za bateri bugabanuka, imiterere mibi y’impapuro za bateri zikoreshwa mu gupima imikorere yazo, ndetse n’umuvuduko w’ibicuruzwa ugera kuri 8%. Kugira ngo iki kibazo gikemuke, ikigo cyasimbuje imbuga zo kugenzura imikorere y’ibikoresho bimwe na bimwe n’ibikoresho bya granite.
Nyuma yo gusimburwa, ubushobozi bwo guhagarara neza kw'ibikoresho bwarushijeho kuba bwiza cyane. Mu gihe cy'amezi atandatu yo gukora, imashini ikoresha urubuga rwa granite yahoraga ikora amakosa y'ubugari bw'urupapuro ruri hagati ya ± 2μm, kandi igipimo cy'umusaruro w'ibicuruzwa cyari gifite inenge cyagabanutse cyane kigera munsi ya 3%. Hagati aho, kubera ko urubuga rwa granite rudasaba gupima no kubungabunga neza nk'urupapuro rw'icyuma gishongeshejwe, bizigamira ibigo amafaranga menshi yo kubungabunga ibikoresho n'igihe cyo kubikora buri mwaka, kandi byongera umusaruro ku kigero kirenga 15%.
Mu gusoza, mu ikoreshwa ry’urusobe rw’ibikoresho bicunga imikorere y’imashini zicunga bateri ya lithium, granite, ifite imiterere myiza y’ibikoresho byayo, irusha cyane icyuma gikozwe mu cyuma mu buryo buhamye. Byaba ari ukureba imiterere y’ibikoresho, amakuru y’igerageza, cyangwa ingaruka zifatika zo kubikoresha, granite itanga garanti yizewe yo gukora neza no mu buryo buhamye ibikorwa byo gucunga bateri ya lithium. Hamwe no kunoza ubwiza bw’ibicuruzwa mu nganda zicunga bateri ya lithium, urusobe rw’ibikoresho bicunga imikorere y’imashini zi ...
