Mukugadzira mabhatiri e-lithium, muchina wekuputira, sechinhu chakakosha chemidziyo, basa rayo rekutanga rinokanganisa zvakananga kurongeka uye kunaka kwechigadzirwa chemabhatiri e-lithium. Kusiyanisa kwekushisa chinhu chakakosha chinokanganisa kugadzikana kwemichina yekuputira. Musiyano wekupikiswa kwekushisa pakati pemagadziko egranite uye mabhesi esimbi yakakandwa yave yakakosha yekutarisisa kusarudzwa kwemidziyo mumabhizinesi ekugadzira lithium bhatiri. .
Coefficient yekuwedzera kwekupisa: Iyo "tembiricha yekudzivirira" mukana wegranite
Iyo coefficient yekuwedzera kwekupisa inosarudza kugadzikana kwedimensional yezvinhu kana tembiricha ichichinja. Iyo coefficient yekuwedzera kwekushisa kwesimbi yakakandwa yesimbi inenge 10-12 × 10⁻⁶/℃. Munzvimbo yakajairwa tembiricha yekuchinja kweiyo lithium bhatiri coating workshops, kunyangwe kudiki shanduko yetembiricha inogona kukonzera kwakakosha dimensional deformation. Semuyenzaniso, kana tembiricha muwekishopu ichichinja ne5℃, 1-mita-yakareba chigadziko chesimbi chinogona kuita 50-60 μm yekuwedzera uye kutsikisa dhizaini. Iyi deformation inokonzeresa shanduko pakati peiyo yekubikira roller uye pepa re electrode, zvichikonzera kusaenzana kwekuputira ukobvu uye zvichizokanganisa kugona uye kuenderana kwemabhatiri e lithium. .
Kusiyana neizvi, coefficient of thermal expansion of the granite base inongova (4-8) × 10⁻⁶/℃, iyo inenge hafu yesimbi yakakandwa. Pasi peiyo tembiricha yekuchinja kwe5 ℃, deformation ye1-mita-yakareba granite base ingori 20-40 μm, uye shanduko yedimensional ingangoita kufuratirwa. Munguva yenguva yakareba inoenderera mberi yekugadzirwa kwekugadzira, nheyo yegranite inogona kugara ichichengetedza chimiro chakagadzikana, ichichengetedza nzvimbo chaiyo yehukama pakati pekuputira roller uye pepa re electrode, kuchengetedza kugadzikana kwemaitiro ekuputira, uye kupa chivimbiso chechokwadi chekugadzirwa kwebhatiri ye lithium yakasimba. .
Thermal conductivity: Iyo "heat insulation barrier" hunhu hwegranite
Pamusoro pekuchinja kwedimensional kunokonzerwa nekuwedzera kwekupisa, iyo thermal conductivity yezvinhu inokanganisawo kufanana kwekugovera tembiricha mumidziyo. Cast iron ine yakanaka yekupisa conductivity. Kana kupisa kuchigadzirwa mukati memuchina wekuputira nekuda kwekushanda kwemota, kukweshera kweiyo yekubikira roller, nezvimwewo, iyo cast iron base inomhanyisa kupisa, zvichikonzera kupisa kwepasi kwechigadziko kukwira uye kugovaniswa zvisina kufanira. Musiyano wetembiricha uyu unokonzeresa kushushikana kwekushisa pachigadziko, zvichiwedzera kuwedzera deformation. Panguva imwecheteyo, zvinogona zvakare kukanganisa kushanda kwakajairwa kweakatenderedza ma sensors uye zvinhu zvekutonga. .
Granite ine urombo conductor wekupisa, ine thermal conductivity ye 2.7-3.3W / (m · K) chete, iyo yakaderera zvikuru kupfuura yesimbi yakakandwa pa40-60W / (m · K). Munguva yekushanda kwemuchina wekuputira, iyo granite base inogona kunyatso kuvharira kuitisa kwemukati kupisa, kuderedza kushanduka kwekushisa pachigadziko chepasi uye chizvarwa chekupisa kwekushushikana. Kunyangwe kana muchina wekuputira uchishanda pasi pemutoro wakareba kwenguva yakareba, chigadziko chegranite chinogona kuramba chakatsiga tembiricha mamiriro, kudzivirira deformation yemidziyo uye kushatisa kwekuita kunokonzerwa nekusaenzana tembiricha, uye kugadzira yakagadzikana tembiricha nharaunda yekugadzira. .
Kugadzikana pasi petembiricha bhasikoro: Iyo "yenguva refu tembiricha kuramba" kugona kwegranite
Kugadzirwa kwemabhatiri e-lithium kazhinji kunoda michina kuti ishande isingaperi kwenguva yakareba. Munguva yenguva zhinji tembiricha kutenderera (sekutonhora husiku uye kupisa mukati mezuva), kugadzikana kwezvinhu zvepasi kwakakosha kwakakosha. Pasi pemaitiro anodzokororwa ekuwedzera kwekupisa uye kuputika, chigadziko chesimbi chinowanzoita kuneta kutsemuka mukati, zvichikonzera kuderera kwesimba rekugadzirisa uye kukanganisa hupenyu hwebasa remidziyo. Yakakodzera data yekutsvagisa inoratidza kuti mushure me1000 tembiricha kutenderera (ine tembiricha yemhando ye20-40 ℃), iyo yekutsemuka kwepamusoro kweiyo cast iron base inogona kusvika 0.1-0.2mm. .
Mabhesi eGranite ane yakanakisa kuneta kuramba nekuda kweyakaomesesa yemukati yemaminerari ekristaro chimiro. Pasi pemamiriro akafanana ekushisa bhasikoro bvunzo mamiriro, gasi regranite hariratidze kutsemuka kuri pachena, uye kutendeseka kwechimiro kunochengetwa kwenguva yakareba. Uku kugadzikana kwepamusoro pasi pekushisa bhasikoro kunoita kuti chigadziko chegranite chisangane nepamusoro-soro uye kwenguva refu yekushanda kwezvinodiwa zve lithium bhatiri kugadzirwa, kuderedza kuwanda kwekugadzirisa uye kuderera kwemidziyo inokonzerwa nezvinetso zvepasi nekuvandudza kushanda kwekugadzira. .
Zvichipesana nemashure ekuwedzera kwakasimba zvinodiwa zvekunyatso uye kugadzikana mukugadzira lithium bhatiri, mabhesi egranite, ane yakaderera coefficient yekuwedzera kwekupisa, yepamusoro yekupisa conductivity uye yakasarudzika tembiricha yebhasikoro kugadzikana, zvakanyanya kukunda mabhesi esimbi akakandwa maererano nekushomeka kwekushisa. Kusarudza lithium bhatiri rekuisa muchina rine granite base kunogona kunyatso kusimudzira coating, kuve nechokwadi chemhando yezvigadzirwa zvemabhatiri e-lithium, kuderedza njodzi dzemidziyo panguva yekugadzira, uye kuve tsigiro yakakosha yekusimudzira kusimudzira kweiyo lithium bhatiri indasitiri kusvika pakuita kwepamusoro.
