Ukuhlaziywa Okunamandla Ekuthuthukisweni Kokuzinza Kwe-Dimensional kwegwadle phezu kwensimbi ecijile kuplathifomu yokulawula ukunyakaza yomshini wokuhlanganisa ibhethri ye-Lithium.

.
Enkambweni yokukhiqiza amabhethri e-lithium-ion, inqubo yokugqoka, njengesixhumanisi esiyinhloko, ithinta ngokuqondile ukusebenza nokuphepha kwamabhethri. Ukuzinza kwesiteji sokulawula ukunyakaza komshini wokuhlanganisa ibhethri ye-lithium kudlala indima enqumayo ekunembeni kokugqoka. I-Granite ne-cast iron, njengezinto ezisetshenziswa kakhulu zeplathifomu, umehluko ekuzinzeni kwazo kobukhulu udonse ukunaka okukhulu. Lesi sihloko sizohlaziya ngokujulile ukuthuthukiswa okubalulekile kokuzinza kwe-dimensional kwegwadle uma kuqhathaniswa nensimbi esakazwayo endaweni yokulawula ukunyakaza yemishini yokumboza ibhethri ye-lithium ngokusebenzisa izakhiwo zezinto ezibonakalayo, idatha yokuhlola kanye namacala okusebenza angokoqobo. .
Izinto ezibonakalayo zinquma isisekelo sokuzinza
I-Cast iron, njengento evamile yezimboni, yake yasetshenziswa kabanzi emkhakheni wezinkundla zokulawula ukunyakaza ngenxa yokusebenza kwayo okuhle kakhulu kokulingisa kanye nezinzuzo zezindleko. Kodwa-ke, izinto zensimbi ezisansimbi zineziphambeko ezingokwemvelo. Isakhiwo sayo sangaphakathi siqukethe inani elikhulu le-flake graphite, elilingana nokuqhekeka kwangaphakathi futhi kuzonciphisa ukuqina okuphelele kwezinto. Phakathi naleso sikhathi, i-coefficient yokwanda okushisayo kwensimbi ekhonjiwe iphakeme ngokuqhathaniswa, cishe 10-12 × 10⁻⁶/℃. Ngaphansi kokuqoqwa kokushisa okukhiqizwa ukusebenza kwesikhathi eside kwe-lithium battery coating, ithambekele ekuguqukeni kokushisa. Ngaphezu kwalokho, kukhona ingcindezi yokuphonsa ngaphakathi kwe-cast iron. Ngokuhamba kwesikhathi, ukukhululwa kwengcindezi kuzodala izinguquko ezingenakuhlehliswa kusayizi weplathifomu, okuthinta ukunemba kokumboza. .

I-Granite iyimpahla yemvelo eyakhiwe ngezinqubo ze-geological phakathi namakhulu ezigidi zeminyaka. Isakhiwo sayo sekristalu sangaphakathi siminyene futhi siyafana, futhi sinokuzinza okuphezulu kwemvelo. I-coefficient yomugqa yokunwetshwa kwegwadle ingu-0.5-8×10⁻⁶/℃ kuphela, engu-1/2-1/3 yaleyo yensimbi ewugqinsi, futhi ayizweli ngokwedlulele ekushintsheni kwezinga lokushisa. Ngaleso sikhathi, i-granite iqinile ekuthunjweni, inamandla okucindezela afinyelela ku-1,050-14,000 kilograms per square centimeter. Ingakwazi ukumelana ngokuphumelelayo nemithelela yamandla angaphandle nokudlidliza, inikeze isisekelo esiqinile nesizinzile seplathifomu yokulawula ukunyakaza. Cishe akukho ukucindezeleka okuyinsalela ngaphakathi kuyo, futhi ngeke kubangele izinguquko zobukhulu ngenxa yokukhululwa kwengcindezi, iqinisekisa ukuzinza kobukhulu beplathifomu kusukela kungqikithi yezinto. .
Idatha yokuhlola iqinisekisa umehluko wokusebenza
Ukuze uqhathanise ngokubonakalayo umehluko wokuzinza kwe-dimensional phakathi kwe-granite ne-cast iron, ithimba locwaningo lenze ukuhlolwa okukhethekile. Amapulatifomu amabili okulawula ukunyakaza omshini wokumboza ibhethri le-lithium wokucaciswa okufanayo akhethiwe, enziwe nge-granite nensimbi ephonswe ngokulandelana, futhi ahlolwe ngaphansi kwezimo ezifanayo zemvelo. Ukuhlolwa kulingise isimo sangempela sokusebenza somshini wokuhlanganisa ibhethri le-lithium. Ngokuqhubeka nokusebenzisa imishini, izinguquko zosayizi weplathifomu ngezikhathi ezihlukene zaqashwa. .
Imiphumela yokuhlola ibonisa ukuthi ngemva kokusebenza okuqhubekayo amahora angu-24, ngenxa yokushisa okukhiqizwe ukusebenza kwemishini, izinga lokushisa elingaphezulu lesiteji sensimbi ecijile lenyuke cishe ngo-15℃, okuholele ekwenyukeni ngo-0.03mm kubude bendlela yokulinganisa yesikhulumi. Ngaphansi kwezimo ezifanayo, ukuhluka kosayizi weplathifomu yegwadle cishe akunakwa, futhi ububanzi bayo bokuguquguquka kosayizi bungaphansi kuka-0.005mm. Ngemuva kwamahora angu-1000 okuhlolwa kokuguga kwesikhathi eside, ngenxa yokukhululwa kwengcindezi yangaphakathi kanye nokuqoqwa kokuguqulwa kwe-thermal, iphutha le-flatness yesikhulumi se-cast iron lanwetshwa kusukela ku-0.01mm yokuqala kuya ku-0.05mm. Iphutha le-flatness yesikhulumi se-granite lihlala ligcinwe ngaphakathi kuka-0.015mm, futhi inzuzo yokuzinza kwe-dimensional isobala. .
Izimpumelelo ezimangalisayo ezinhlelweni zokusebenza
Ekukhiqizeni kwangempela kwebhizinisi elikhulu lokukhiqiza ibhethri ye-lithium, amapulatifomu okulawula ukunyakaza kwensimbi yake yasetshenziswa. Njengoba isikhathi sokusebenza sezinto zokusebenza sikhula, ukunemba kokumboza kwehle kancane kancane, okubangele ukujiya okungalingani, ukungahlanganisi kahle kwamashidi e-electrode yebhethri, kanye nezinga lomkhiqizo onesici elifinyelela ku-8%. Ukuze kuxazululwe le nkinga, inkampani yashintsha amapulatifomu okulawula ukunyakaza kwezinye izinto zokusebenza ngezinto ze-granite. .
Ngemva kokushintshwa, ukuzinza kwe-dimensional kwemishini kuye kwathuthukiswa kakhulu. Phakathi nomjikelezo wokukhiqiza wezinyanga eziyisithupha, umshini wokumboza osebenzisa iplatifomu yegwadle uhlale ugcina iphutha logqinsi lokumboza ngaphakathi kuka-±2μm, futhi izinga lomkhiqizo elingasebenzi lehliswe kakhulu laba ngaphansi kuka-3%. Khonamanjalo, njengoba amapulatifomu egwadle engadingi ukulinganisa nokugcinwa okunembayo okuvamile njengezingxenyekazi zensimbi ecijile, zonga amabhizinisi inani elibalulekile lezindleko zokulungisa imishini nesikhathi sokuphumula minyaka yonke, futhi andise ukusebenza kahle kokukhiqiza ngaphezu kuka-15%. .
Sengiphetha, ekusetshenzisweni kwesiteji sokulawula ukunyakaza kwemishini yokumboza ibhethri ye-lithium, i-granite, enezinto zayo ezibonakalayo ezivelele, idlula ngokuphawulekayo insimbi ephonswe ngokuzinza kwe-dimensional. Kungakhathaliseki ukuthi ngokombono wemvelo yezinto ezibonakalayo, idatha yokuhlola, noma imiphumela yohlelo lokusebenza olusebenzayo, i-granite inikeza isiqinisekiso esithembekile sokunemba okuphezulu nokukhiqiza okuzinzile kwezinqubo zokumboza ibhethri ye-lithium. Ngokuthuthuka okuqhubekayo kwezidingo zekhwalithi yomkhiqizo embonini yebhethri ye-lithium, izinkundla zokulawula ukunyakaza ezenziwe ngegwadle zizoba yisinqumo esijwayelekile embonini.
