Ukuqhathaniswa kokusebenza kokumelana nezinga lokushisa phakathi kwesisekelo se-granite kanye nesisekelo sensimbi esakhiwe somshini wokuhlanganisa ibhethri le-lithium.

.
Enkambweni yokukhiqiza amabhethri e-lithium, umshini wokugcoba, njengengxenye eyinhloko yemishini, ukusebenza kwayo okuyisisekelo kuthinta ngokuqondile ukunemba kokugqoka kanye nekhwalithi yomkhiqizo wamabhethri e-lithium. Ukushintshashintsha kwezinga lokushisa kuyisici esibalulekile esithinta ukuzinza kwemishini yokumboza. Umehluko wokumelana nezinga lokushisa phakathi kwezisekelo ze-granite nezisekelo ze-cast iron usuphenduke ukucatshangelwa okubalulekile ekukhethweni kwemishini emabhizinisini okukhiqiza ibhethri ye-lithium. .
I-coefficient yokunwetshwa kwe-thermal: Inzuzo "yezinga lokushisa" legwadle
I-coefficient yokunwetshwa kwe-thermal inquma ukuzinza kwe-dimensional kwento uma izinga lokushisa lishintsha. I-coefficient yokunwetshwa okushisayo kwesisekelo sensimbi ekhonjiwe cishe i-10-12 × 10⁻⁶/℃. Esimweni esivamile sokushintshashintsha kwezinga lokushisa kwezinkundla zokusebenzela zokuhlanganisa ibhethri le-lithium, ngisho noshintsho oluncane lokushisa lungadala ukuwohloka kobukhulu obubalulekile. Isibonelo, lapho izinga lokushisa endaweni yokusebenzela liguquguquka ngo-5℃, isisekelo sensimbi esiyimitha elingu-1 ubude singase sinwetshwe ngo-50-60 μm kanye nokuwohloka kokufinyela. Lokhu kuguqulwa kuzodala ushintsho kugebe phakathi kwe-roller enamathelayo kanye neshidi le-electrode, okuholela ekugqileni okungalingani futhi kamuva kuthinte umthamo nokuvumelana kwamabhethri e-lithium. .

Ngokuphambene, i-coefficient yokunwetshwa okushisayo kwesisekelo se-granite kuphela (4-8) ×10⁻⁶/℃, cishe ingxenye yensimbi ekhonjiwe. Ngaphansi kokuguquguquka okufanayo kwezinga lokushisa kuka-5℃, ukuwohloka kwesisekelo segwadle esingamamitha angu-1 ubude singama-20-40 μm kuphela, futhi uguquko lwe-dimensional lungacishe lunganakwa. Phakathi nenqubo yokukhiqiza eqhubekayo yesikhathi eside, isisekelo se-granite singahlala sigcina isimo esizinzile, siqinisekisa isikhundla esiqondile esihlobene phakathi kwe-coating roller kanye neshidi le-electrode, ukugcina ukuqina kwenqubo yokumboza, nokunikeza isiqinisekiso esinokwethenjelwa sokukhiqizwa kwamabhethri e-lithium angaguquki kakhulu. .
I-Thermal conductivity: Isici "sokuvimba ukushisa" kwegwadle
Ngokungeziwe ekushintsheni kwe-dimensional okubangelwa ukunwetshwa kwe-thermal, i-thermal conductivity yezinto nayo ithinta ukufana kokusabalalisa kwezinga lokushisa kumishini. I-cast iron ine-conductivity enhle ye-thermal. Lapho ukushisa kukhiqizwa ngaphakathi komshini wokumboza ngenxa yokusebenza kwemoto, ukungqubuzana kwe-coating roller, njll., isisekelo sensimbi esisansimbi sizoqhuba ukushisa ngokushesha, okubangela ukuthi izinga lokushisa elingaphezulu lesisekelo likhuphuke futhi lisakazwe ngokungalingani. Lo mehluko wokushisa uzobangela ukucindezeleka okushisayo esisekelweni, kuqhubekisele phambili ukwakheka kwe-deformation. Ngesikhathi esifanayo, kungase futhi kuthinte ukusebenza okuvamile kwezinzwa zokunemba ezizungezile kanye nezingxenye zokulawula. .
I-Granite iyi-conductor empofu yokushisa, ene-thermal conductivity ye-2.7-3.3W / (m · K kuphela), ephansi kakhulu kune-cast iron ku-40-60W / (m · K). Ngesikhathi sokusebenza komshini wokumboza, isisekelo se-granite singavimbela ngokuphumelelayo ukuqhutshwa kokushisa kwangaphakathi, ukunciphisa ukushintshashintsha kwezinga lokushisa endaweni yesisekelo kanye nesizukulwane sokucindezeleka okushisayo. Ngisho noma umshini wokumboza usebenza ngaphansi komthwalo omkhulu isikhathi eside, isisekelo se-granite sisengakwazi ukugcina isimo sokushisa esizinzile, sigwema ukuguqulwa kwemishini kanye nokuwohloka kokusebenza okubangelwa izinga lokushisa elingalingani, nokudala indawo yokushisa ezinzile yenqubo yokumboza. .
Ukuzinza ngaphansi kokuhamba ngebhayisikili kwezinga lokushisa: Ikhono "lokumelana nezinga lokushisa lesikhathi eside" legwadle
Ukukhiqizwa kwamabhethri e-lithium ngokuvamile kudinga ukuthi imishini isebenze ngokuqhubekayo isikhathi eside. Phakathi nemijikelezo yezinga lokushisa evamile (njengokupholisa ebusuku nokushisisa emini), ukuzinza kwezinto eziyisisekelo kubaluleke kakhulu. Ngaphansi komphumela ophindaphindiwe wokwandisa nokunciphisa okushisayo, isisekelo sensimbi ekhonjiwe sijwayele ukuqhekeka kokukhathala ngaphakathi, okuholela ekunciphiseni kwamandla esakhiwo futhi kuthinte impilo yesevisi yemishini. Idatha yocwaningo efanelekile ibonisa ukuthi ngemva kwemijikelezo yezinga lokushisa engu-1000 (enobubanzi obuhlukahlukene bokushisa obungu-20-40℃), ukujula kokuqhekeka okungaphezulu kwesisekelo se-cast iron kungafinyelela ku-0.1-0.2mm. .
Izisekelo ze-Granite zinokumelana nokukhathala okuhle kakhulu ngenxa yesakhiwo sazo sekristalu yamaminerali aminyene. Ngaphansi kwezimo ezifanayo zokuhlola izinga lokushisa lokuhamba ngebhayisikili, isisekelo se-granite asibonisi neze imifantu esobala, futhi ubuqotho besakhiwo bugcinwa isikhathi eside. Lokhu kuzinza okuphezulu ngaphansi kokuhamba kwamabhayisikili okushisa kwenza isisekelo se-granite sihlangabezane nezidingo zokuqina okuphezulu nokusebenza kwesikhathi eside kokukhiqizwa kwebhethri ye-lithium, ukunciphisa imvamisa yokugcinwa nokunciphisa isikhathi semishini ebangelwa izinkinga zesisekelo kanye nokuthuthukisa ukusebenza kahle kokukhiqiza. .
Ngokumelene nokwasemuva kwezidingo eziqinile eziqinile zokunemba nokuzinza ekwenziweni kwebhethri ye-lithium, izisekelo ze-granite, ezine-coefficient yazo ephansi yokwanda okushisayo, ukuqhutshwa kwe-thermal okuphezulu kanye nokuzinza okuvelele kokuhamba kwamabhayisikili, zidlula kakhulu izisekelo zensimbi ekhonjiwe ngokwezinga lokushisa. Ukukhetha umshini wokumboza webhethri we-lithium onesisekelo se-granite kungathuthukisa ngempumelelo ukunemba kokunamathela, kuqinisekise ikhwalithi yemikhiqizo yebhethri ye-lithium, kunciphise ubungozi bemishini ngesikhathi senqubo yokukhiqiza, futhi kube usekelo olubalulekile lokugqugquzela ukuthuthukiswa kwemboni yebhethri ye-lithium ekusebenzeni okuphezulu.
