Guhitamo uburyo bwo gutwikira ni iki?

Hariho uburyo bwinshi bwo gutwikira. Uburyo bwo gutwika amavuta burimo gushira, gusiga umuzingo, gutwikira inkoni, hamwe ninsinga - gukomeretsa inkoni, n'ibindi. Hano hepfo turamenyekanisha muri make ubundi buryo bwo gutwikira.

Kwibiza ni uburyo bwo gutwikisha urubuga ahora rwinjizwamo kandi rugakurwa mu kigega cya shitingi, hanyuma ibishishwa birenze bigasubira mu kigega, nkuko bigaragara ku gishushanyo cya 5 - 89. Gufata ibishishwa mubisanzwe bikubye kabiri {{3} ating kuruhande, bityo icyerekezo cyo gukurura cyurubuga muri rusange ni perpendicular hejuru yubuso bwamazi kugirango harebwe ko umubyimba wububiko kumpande zombi zurubuga. Mubisanzwe, uburebure bwa coater buterwa nubwiza, ubucucike, umuvuduko wumurongo, hamwe no gukuramo inguni. Umubyimba utwikiriye uburinganire hejuru yurubuga ugenda ubyibuha uko ibishishwa byihuta kandi byihuta byiyongera. Byumvikane ko gushira hamwe nabyo bikwiranye nigihe gito cyo gukora imirimo igoye, ariko mugihe igipimo cyo guhindagurika cyihuta, hazabaho umuvuduko.

Igipfundikizo cya blade nuburyo bwo gutwikira bukoresha icyuma kugirango ugabanye umubyimba utwikiriye neza kuri lisiti cyangwa urubuga kugeza ku mubyimba wagenwe, nkuko bigaragara ku gishushanyo cya 5 - 90. Muri byo, umubyimba wububiko hamwe nuburemere bwikirere cyumwuka - gutwikira icyuma biterwa nikirere - umuvuduko wicyuma n'umuvuduko windege, kandi birakwiriye cyane cyane gutwikira - ubukonje buke cyangwa hagati - hasi - amazi yubukonje -. Mugihe ukoresheje ibimera bishingiye kumashanyarazi, hagomba kwitonderwa kugirango hatabaho imvange ziturika zituruka kumyuka myinshi hamwe numwuka wumuyaga.

Igipfundikizo c'umwenda ni uburyo bwo gutwikamo ibishishwa biva mu mwanya hanyuma bikagwa ku rubuga rukora mu buryo bw'umwenda utemba. Nuburyo bwateganijwe bwo gutwikira, nkuko bigaragara ku gishushanyo cya 5 - 91. Kuberako intera iri hagati yo gukuramo ipfa iminwa nurubuga ni runini kandi nta mwuka uhumeka uri kuri perido, ifite ibyiza byingenzi mugukuraho inenge nko guhambira no gushushanya. Bitewe nimbaraga nini za kinetic yumwenda, ifasha guhagarika menisk, bityo umuvuduko mwinshi wo gutwikira urashobora kugerwaho. Umuvuduko wumurongo urashobora kugera kuri m / min zirenga 100 kandi uragenda ukoreshwa mubisubizo byuzuye bya batiri.

Umugozi - gukomeretsa inkoni ni uburyo bwo gutwikira bukoresha insinga - inkoni yo gupima ibikomere kugirango yambare umwenda umwe kurubuga rworoshye, nkuko bigaragara ku gishushanyo cya 5 - 92. Umugozi - inkoni yakomeretse ikozwe nuruziga rukomeye rwuma rutagira ibyuma ruzengurutse inkoni yibanze. Umugozi - inkoni yakomeretse nanone yitwa inkoni ya coating cyangwa inkoni ya muganga. Iyo insinga izunguruka ari ntoya cyane, uburebure bwa coating burashobora kugera muri microne nkeya. Kuberako amazi make - yimyunyu ngugu itemba byoroshye kurugozi rwicyuma cyakomeretse, birakwiriye gutwikira amazi mabi. Ukoresheje inkoni zidasanzwe zo gutwikira, ubwiza bwa coating burashobora kuba hejuru, kandi uburebure bwa coating burashobora gushika kuri 225 mm. Umuvuduko wo gutwikira inkoni muri rusange ugarukira kuri 304 m / min.

Guhitamo uburyo bwo gutwikira ni umushinga utunganijwe hamwe nibintu byinshi ugomba gusuzuma. Ibikurikira nibintu byingenzi bigomba kwitabwaho muguhitamo uburyo bwo gutwikira:

Uburyo bwinshi bwo gutwikira burakwiriye gutwikira igipande kimwe icyarimwe, ikindi gipfundikirwa nyuma yicyuma kibanziriza. Uburyo bumwe bushobora gutwikira ibice byinshi icyarimwe, nkibishushanyo mbonera, bishobora gutwikira byibuze ibice 9 icyarimwe mugihe cyo gutwika firime. Umutwe utwikiriye umwenda utwikiriye niwo mutwe utwikiriye umutwe, kandi igipfundikizo nacyo gitemba ku nkombe, bityo igipande kinini nacyo gishobora gukorwa. Ahantu - apfa gutwikirwa no gutwikisha ibintu mubisanzwe bikora igipande kimwe -, ariko birashobora no kugira ibibanza bibiri cyangwa bitatu byo gukuramo ibice byinshi bisabwa cyane nabakora batiri ya lithium - ion.

Umugozi - gutwikisha inkoni bikwiranye no gutwikira -; gusohora ibishishwa, guhindagura umuzingo, hamwe no gutwikira umwenda bikwiranye no gutwikira umubyimba, ushobora kugera kuri 400-750 mm. Muri rusange nukuvuga, uko igipfundikizo cyoroheje, niko bigoye cyane. Twabibutsa ko ubunini buvuzwe hano nuburinganire butose, kandi itandukaniro riri hagati yumye yumye hamwe nigitambaro kinini.

Viscosity and viscoelasticity ni ubwinshi bwumubiri bugaragaza imiterere ya rheologiya. Buri buryo bwo gutwikira bufite urwego runaka rwubukonje bukwiye hamwe nigipimo cyogosha. Ubushuhe bwa slurry bwatoranijwe neza ukurikije ubukonje bupimye ku gipimo cyogosha, kubera ko ububobere buhinduka nigipimo cyogosha. Kubijyanye na batiri ya lithium itangwa na lithium iyobora - ion itanga ibikoresho bya batiri, kugenzura neza ibicucu byahindutse ikintu cyingenzi mubikorwa bihamye. Nubwo bimeze bityo ariko, muburyo buteganijwe bwo gutwikira, igipimo cyogosha gikunze gukoreshwa ni kinini cyane, kuburyo bigoye kugera kuri kiriya gipimo kinini cyo gukata hamwe nibikoresho bigezweho, bityo igereranya rya viscosity rirakomeye, kandi amaherezo ibisubizo byubushakashatsi bizatsinda. Nubwo viscoelasticité ari ngombwa cyane, biragoye guhanura. Viscoelasticitike imwe ifasha kunoza imikorere yimyenda imwe, ariko ubukonje bwinshi burashobora gutera gutinda gukurura inenge.

Ahantu heza - bipfira, gutwikisha slide, no gutwikisha umwenda bifite uburinganire buhanitse, mugihe ubundi buryo bwo gutwikira bushingiye kumiterere y'amazi, geometrike, umuvuduko wo kuzunguruka, nibindi bintu. Uburyo bwose bwo gutwikira bufite intera yagutse, biterwa nuburyo nuburyo bwo gukora igikoresho. Gusa mugutezimbere cyane ibikoresho bya batiri electrode yo gutwikira birashobora kuboneka ibisubizo byiza byo gutwikira.

Urubuga rushobora kuba - rworoshye cyangwa rworoshye. Kurubuga rwemewe, imyenge irashobora gufungwa mbere yo gutwikira. Birakenewe kandi gusuzuma ubukana hamwe nubushyuhe bwo hejuru kurubuga. Ubuso bwubuso bwibicucu bugomba kuba munsi yurubuga.

Umuvuduko wo gutwikira ujyanye no gukora neza. Iyo bishoboka, byihuse umuvuduko wo gutwikira, nibyiza. Uburyo bwose bwo gutwikira bufite umuvuduko ntarengwa, ariko uburyo bumwe nibyiza kurwego rwo hejuru -. Ipitingi isaba igipimo ntarengwa cyo gutembera kugirango umwenda utangirika, bityo - gutwikira umuvuduko ntibishobora gukorwa mugihe urwego ruto. Mugushushanya kurupapuro, mugihe igipfundikizo cyoroshye cyane, igipfundikizo kizaba kidahagaze. Umuvuduko mwinshi hamwe nuburinganire bwimbitse bifasha kwirinda guhuzagurika. Muri ubwo buryo, Urubuga rworoshye kandi rutari - rushobora gutwikirwa umuvuduko mwinshi. Umuvuduko wo gutwikira nawo ujyanye n'uburebure bw'igice cyumye. Igihe kinini cyumye, niko ari byiza kongera igipimo cyumye.

Uburyo bwo gutwikira hamwe nuburyo bukoreshwa bwerekanwe kumeza 5-6.

Uburyo bwo gutwikira lithium - ion ya batiri ya electrode yamashanyarazi ni cyane cyane gutwikisha no gukuramo ibicuruzwa. Ihindurangingo risubiza inyuma risaba igipimo cyinshi cyo hejuru, gikwiranye nubushuhe hamwe nubushuhe buke buke, bukabona firime nini cyane kandi nziza, kandi kuri ubu nuburyo bukoreshwa cyane muri bateri ya litiro - ion. Gukuramo ibicuruzwa byerekana tekinoroji yo gutera imbere mu nganda. Umuvuduko runaka ushyirwa kumurongo mugihe cyo gutwikira, ushobora gukoreshwa mugutwikiriza ibishishwa byinshi. Urupapuro rwabonetse rwa electrode rufite ibisobanuro bihanitse kandi byihuta. Hamwe nogutezimbere kwiterambere rya tekinoroji ya batiri ya lithium no kongera ibyifuzo biva mubakora batiri ya lithium - ion kugirango ingufu nyinshi kandi zihamye, gutwika ibicuruzwa, gushyigikirwa na leta - ya - ibikoresho bya elegitoroniki ya elegitoroniki ya elegitoronike hamwe n’ibisubizo bihanitse bya - bizakoreshwa cyane.
