Muchigadziro chekugadzira mabhatiri e-lithium-ion, nzira yekuputira, sechinhu chinokosha chekubatanidza, inobata zvakananga kushanda uye kuchengetedzwa kwemabhatiri. Iko kugadzikana kweiyo inofamba inodzora chikuva ye lithium bhatiri yekuputira muchina inoita basa rakasarudzika mukurongeka kwekuvhara. Granite uye simbi yakakandwa, sezvinowanzo shandiswa papuratifomu zvinhu, mutsauko mukugadzikana kwavo kwechimiro wakwezva kutarisisa kwakawanda. Ichi chinyorwa chichaongorora zvakadzama kuvandudzwa kwakakosha mukugadzikana kwegranite kana ichienzaniswa nesimbi yakakandwa papuratifomu inodzora yelithium bhatiri yekuputira michina kuburikidza nemidziyo yezvinhu, data rekuyedza uye zviitiko zvinoshanda zvekushandisa. .
Zvinhu zvezvinhu zvinotarisa hwaro hwekugadzikana
Cast iron, sechinyakare maindasitiri zvinhu, yaimboshandiswa zvakanyanya mumunda wemapuratifomu ekudzora mafambiro nekuda kwekuita kwayo kwakanaka kwekukanda uye mutengo wakanakira. Nekudaro, simbi yakakandwa ine hurema hwekuzvarwa. Chimiro chayo chemukati chine huwandu hwakawanda hweflake graphite, iyo yakaenzana nekutsemuka kwemukati uye inoderedza kuomarara kwese kwezvinhu. Zvichakadaro, iyo coefficient yekuwedzera kwekupisa kwesimbi yakakandwa yakakwira, inenge 10-12 × 10⁻⁶/℃. Pasi pekuunganidza kwekupisa kunokonzerwa nekushanda kwenguva refu kwe lithium battery coating, inotarisana nekupisa kwekushisa. Pamusoro pezvo, pane kukanda kushushikana mukati mesimbi yakakandwa. Nekufamba kwenguva, kuburitswa kwekushushikana kunokonzeresa shanduko isingachinjike muhukuru hwepuratifomu, zvichikanganisa kurongeka kwehuku. .
Granite chinhu chechisikigo chakaumbwa kuburikidza ne geological process pamusoro pemazana emamiriyoni emakore. Yayo yemukati yekristaro chimiro chakakora uye yunifomu, uye ine inherent yakakwirira kugadzikana. Iyo mutsara yekuwedzera coefficient yegranite ingori 0.5-8 × 10⁻⁶/℃, iri 1/2-1/3 yeiyo yesimbi yakakandwa, uye haina hanya zvakanyanya nekushanduka kwekushisa. Zvichakadaro, granite yakaoma mukugadzirwa, ine simba rekumanikidza kusvika 1,050-14,000 kilograms per square centimeter. Inogona kurwisa zvinobudirira simba rekunze uye kudengenyeka, ichipa hwaro hwakasimba uye hwakasimba hweiyo inofamba inodzora chikuva. Iko kunenge kusina kusara kunetseka mukati mayo, uye hazvizokonzerese shanduko nekuda kwekushungurudzika kusunungurwa, kuve nechokwadi chekugadzikana kwedimensional yepuratifomu kubva pachinhu chechinhu. .
Data yekuedza inosimbisa kusiyana kwekuita
Kufananidza nekuona mutsauko wekugadzikana kwedimensional pakati pegranite nesimbi yakakandwa, timu yekutsvagisa yakaita kuyedza kwakakosha. Mapuratifomu maviri ekudzora eiyo lithium bhatiri yekuputira muchina weiyo yakafanana yakatarwa akasarudzwa, akagadzirwa negranite uye simbi yakakandwa zvichiteerana, uye akaedzwa pasi pemamiriro akafanana ezvakatipoteredza. Kuedza kwacho kwakatevedzera mamiriro chaiwo ekushanda emuchina we lithium bhatiri. Nekuenderera mberi nekumhanyisa michina, saizi shanduko yepuratifomu panguva dzakasiyana dzenguva dzakatariswa. .
Mhedzisiro yekuedza inoratidza kuti mushure mekuenderera mberi kwekushanda kwemaawa makumi maviri nemana, nekuda kwekupisa kunoitwa nekushanda kwemidziyo, tembiricha yepasi peplatform yesimbi yakakandwa yakawedzera neinosvika 15 ℃, zvichikonzera kuwedzera kwe0.03mm mukureba kwakananga dimension yepuratifomu. Pasi pemamiriro akafanana, saizi yekusiyana kwepuratifomu yegranite inenge isingaite, uye saizi yayo inoshanduka iri pasi pe0.005mm. Mushure memaawa e1000 ekuedzwa kwenguva refu kwekuchembera, nekuda kwekusunungurwa kwekushushikana kwemukati uye kuunganidza kwekupisa kwekupisa, kukanganisa kweflatness kwepuratifomu yesimbi yakakandwa yakawedzera kubva pakutanga 0.01mm kusvika 0.05mm. Iko kukanganisa kwekufuratira kwepuratifomu yegranite inogara ichichengetwa mukati me 0.015mm, uye mukana wekugadzikana kwedimensional uri pachena. .
Kubudirira kunoshamisa mumashandisirwo anoshanda
Mukugadzirwa chaiko kwebhizimusi rekugadzira bhatiri re lithium, mapuratifomu ekukanda simbi aimboshandiswa. Sezvo nguva yekushanda yemidziyo yakawedzera, iko kurongeka kwakadzikira zvishoma nezvishoma, zvichikonzera kusaenzana kwekukora, kusawirirana kwebhatiri electrode sheets, uye chiyero chechigadzirwa chakaremara chakakwira se8%. Kugadzirisa dambudziko iri, bhizinesi rakatsiva mapuratifomu ekudzora emamwe maturusi nezvinhu zvegranite. .
Mushure mekutsiva, iyo dimensional kugadzikana kwemidziyo yakagadziridzwa zvakanyanya. Munguva yemwedzi mitanhatu yekugadzira kutenderera, muchina wekuputira uchishandisa chikuva chegranite waigara uchichengeta kukanganisa ukobvu mukati me ± 2μm, uye chiyero chechigadzirwa chakaremara chakaderedzwa zvakanyanya kusvika pasi pe3%. Zvichakadaro, semapuratifomu egranite asingade kudzokororwa kwakaringana uye kugadzirisa semapuratifomu esimbi akakandwa, vanochengetedza mabhizinesi mari yakawanda yekugadziriswa kwemidziyo uye nguva yekudzikira gore rega rega, uye vanowedzera hunyanzvi hwekugadzira neinopfuura 15%. .
Mukupedzisa, mukushandiswa kweiyo motion control platform ye lithium battery coating machines, granite, ine zvinhu zvayo zvakatanhamara, inokunda zvakanyanya simbi yakakandwa maererano nekugadzikana kwedimensional. Zvingave kubva pamaonero echisikigo chenyama, data rekuyedza, kana mhedzisiro yekushandisa, granite inopa vimbiso yakavimbika yemhando yepamusoro-chaiyo uye yakagadzikana kugadzirwa kwe lithium bhatiri coating process. Nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvemhando yezvigadzirwa muindasitiri yebhatiri yelithium, mapuratifomu ekudzora anogadzirwa negranite anosungirwa kuve sarudzo huru muindasitiri iyi.
