Enqubweni yokukhiqiza amabhethri e-lithium, umshini wokumboza, njengengxenye ebalulekile yemishini, ukusebenza kwawo kwesisekelo kuthinta ngqo ukunemba kokumboza kanye nekhwalithi yomkhiqizo wamabhethri e-lithium. Ukwehluka kwezinga lokushisa kuyisici esibalulekile esithinta ukuzinza kwemishini yokumboza. Umehluko ekumelaneni kwezinga lokushisa phakathi kwezisekelo ze-granite nezisekelo zensimbi ephonswe ube yinto ebalulekile ekucatshangelweni kokukhethwa kwemishini emabhizinisini okukhiqiza amabhethri e-lithium.
Isilinganiso sokunwetshwa kokushisa: Inzuzo "yokungavikeleki kokushisa" ye-granite
I-coefficient yokwanda kokushisa inquma ukuzinza kobukhulu bezinto lapho izinga lokushisa lishintsha. I-coefficient yokwanda kokushisa kwesisekelo sensimbi ephonswe cishe i-10-12 ×10⁻⁶/℃. Endaweni evamile yokuguquguquka kokushisa kwezindawo zokusebenzela zokumboza ibhethri le-lithium, ngisho nezinguquko ezincane zokushisa zingabangela ukuguqulwa okukhulu kobukhulu. Isibonelo, lapho izinga lokushisa e-workshop lishintsha ngo-5℃, isisekelo sensimbi ephonswe esingamamitha angu-1 singase sidlule ekukhuleni okungu-50-60 μm kanye nokuguqulwa kokugoba. Lokhu kuguqulwa kuzobangela ushintsho esikhaleni esiphakathi kwe-roller yokumboza kanye neshidi le-electrode, okuholela ekujiyeni kokugqoka okungalingani futhi kamuva kuthinte amandla kanye nokuvumelana kwamabhethri e-lithium.
Ngokuphambene nalokho, i-coefficient yokwanda kokushisa kwesisekelo se-granite ingu-(4-8) ×10⁻⁶/℃ kuphela, okucishe kube yisigamu sensimbi ephonswe. Ngaphansi kokushintshashintsha kokushisa okufanayo okungu-5℃, ukuguqulwa kwesisekelo se-granite esingamamitha angu-1 ubude kungu-20-40 μm kuphela, futhi ushintsho lobukhulu lungacishe lunganakwa. Ngesikhathi senqubo yokukhiqiza eqhubekayo yesikhathi eside, isisekelo se-granite singahlala sigcina isimo esizinzile, siqinisekisa indawo eqondile phakathi kwe-roller yokumboza kanye neshidi le-electrode, silondoloze ukuzinza kwenqubo yokumboza, futhi sinikeze isiqinisekiso esithembekile sokukhiqizwa kwamabhethri e-lithium ahambisana kakhulu.
Ukushisa: "Isithiyo sokuvimbela ukushisa" esibonakala ku-granite
Ngaphezu kwezinguquko zobukhulu ezibangelwa ukwanda kokushisa, ukuhanjiswa kokushisa kwezinto nakho kuthinta ukufana kokusatshalaliswa kokushisa emishinini. Insimbi ephothiwe inokuhanjiswa okuhle kokushisa. Lapho ukushisa kukhiqizwa ngaphakathi komshini wokumboza ngenxa yokusebenza kwemoto, ukungqubuzana kwe-roller yokumboza, njll., isisekelo sensimbi ephothiwe sizoqhuba ukushisa ngokushesha, okubangela ukuthi izinga lokushisa lobuso besisekelo likhuphuke futhi lisatshalaliswe ngokungalingani. Lo mehluko wokushisa uzobangela ukucindezeleka kokushisa esisekelweni, okwandisa ukuguquguquka. Ngesikhathi esifanayo, kungathinta nokusebenza okuvamile kwezinzwa zokunemba ezizungezile kanye nezingxenye zokulawula.
I-Granite iyi-conductor yokushisa empofu, ene-conductivity yokushisa engu-2.7-3.3W/ (m · K kuphela), ephansi kakhulu kuneyensimbi ephonswe ku-40-60W/ (m · K). Ngesikhathi sokusebenza komshini wokumboza, isisekelo se-granite singavimba ngempumelelo ukuqhutshwa kokushisa kwangaphakathi, sinciphise ukushintshashintsha kwezinga lokushisa ebusweni besisekelo kanye nokukhiqizwa kokucindezeleka kokushisa. Ngisho noma umshini wokumboza usebenza ngaphansi komthwalo omkhulu isikhathi eside, isisekelo se-granite sisengagcina isimo sokushisa esizinzile, sigweme ukuguquguquka kwemishini kanye nokuwohloka kokusebenza okubangelwa ukushisa okungalingani, futhi sidale indawo yokushisa ezinzile yenqubo yokumboza.
Ukuzinza ngaphansi kokujikeleza kokushisa: Amandla "okumelana nokushisa kwesikhathi eside" e-granite
Ukukhiqizwa kwamabhethri e-lithium kuvame ukudinga ukuthi imishini isebenze njalo isikhathi eside. Ngesikhathi sokujikeleza okuvamile kokushisa (njengokupholisa ebusuku nokushisa emini), ukuzinza kwezinto eziyisisekelo kubaluleke kakhulu. Ngaphansi komphumela ophindaphindwayo wokwanda nokuncipha kokushisa, isisekelo sensimbi ephonswe sithambekele ekuqhekekeni kokukhathala ngaphakathi, okuholela ekunciphiseni kwamandla esakhiwo futhi kuthinte impilo yesevisi yemishini. Idatha yocwaningo efanele ikhombisa ukuthi ngemva kwemijikelezo yokushisa eyi-1000 (enobubanzi bokushintshashintsha kokushisa obungu-20-40℃), ukujula kokuqhekeka kobuso besisekelo sensimbi ephonswe kungafinyelela ku-0.1-0.2mm.
Izisekelo zegranite zinokumelana okuhle kakhulu nokukhathala ngenxa yesakhiwo sazo esiqinile sekristalu yamaminerali angaphakathi. Ngaphansi kwezimo ezifanayo zokuhlolwa kokujikeleza kokushisa, isisekelo segranite asibonakali kahle imifantu esobala, futhi ubuqotho besakhiwo bugcinwa isikhathi eside. Lokhu kuzinza okuphezulu ngaphansi kokujikeleza kokushisa kwenza isisekelo segranite sikwazi ukuhlangabezana nezidingo zokusebenza ezinamandla kakhulu nezesikhathi eside zokukhiqizwa kwebhethri le-lithium, kunciphisa imvamisa yokugcinwa kanye nesikhathi sokungasebenzi kwemishini okubangelwa izinkinga zesisekelo kanye nokuthuthukisa ukusebenza kahle kokukhiqiza.
Ngenxa yezidingo eziqinile zokunemba nokuzinza ekukhiqizweni kwamabhethri e-lithium, izisekelo ze-granite, ezine-coefficient yazo ephansi yokwanda kokushisa, ukuqhuba kahle kokushisa kanye nokuqina kokujikeleza kokushisa okuvelele, zidlula kakhulu izisekelo zensimbi ecijile maqondana nokumelana nokushisa. Ukukhetha umshini wokumboza ibhethri le-lithium onesisekelo se-granite kungathuthukisa ngempumelelo ukunemba kokumboza, kuqinisekise ikhwalithi yemikhiqizo yebhethri le-lithium, kunciphise izingozi zemishini ngesikhathi senqubo yokukhiqiza, futhi kube ukwesekwa okubalulekile kokukhuthaza intuthuko yemboni yebhethri le-lithium ekusebenzeni okuphezulu.
