Popanga mabatire a lithiamu-ion, njira yokutira, monga cholumikizira chachikulu, imakhudza mwachindunji magwiridwe antchito ndi chitetezo cha mabatire. Kukhazikika kwa nsanja yoyendetsera makina a lithiamu batire lopaka batire kumachita gawo lalikulu pakulondola kwa zokutira. Granite ndi chitsulo choponyedwa, monga zida zomwe zimagwiritsidwa ntchito kwambiri papulatifomu, kusiyana kwa kukhazikika kwawo kwachititsa chidwi kwambiri. Nkhaniyi mozama kusanthula kwambiri patsogolo kukhazikika dimensional wa granite poyerekeza kuponyedwa chitsulo pa zoyenda ulamuliro nsanja ya lifiyamu batire ❖ kuyanika makina kudzera katundu zakuthupi, deta experimental ndi milandu ntchito ntchito. ku
Zinthu zakuthupi zimatsimikizira maziko a bata
Chitsulo chotayira, monga zida zamafakitale, kale chimagwiritsidwa ntchito kwambiri popanga nsanja zowongolera zoyenda chifukwa chakuchita bwino kwambiri komanso mtengo wake. Komabe, zitsulo zotayidwa zimakhala ndi zolakwika zake. Mapangidwe ake amkati ali ndi graphite yambiri ya flake, yomwe imakhala yofanana ndi ming'alu yamkati ndipo idzachepetsa kukhazikika kwazinthuzo. Pakalipano, coefficient of thermal expansion of cast iron iron is high, pafupifupi 10-12 × 10⁻⁶/℃. Pansi pa kudzikundikira kwa kutentha komwe kumapangidwa ndi ntchito yayitali ya lithiamu batire ❖ kuyanika, ndi sachedwa matenthedwe matenthedwe. Kuphatikiza apo, pali kuponyera kupsinjika mkati mwachitsulo chachitsulo. Pakapita nthawi, kutulutsidwa kwa kupsinjika kumayambitsa kusintha kosasinthika pakukula kwa nsanja, kukhudza kulondola kwa zokutira. ku
Granite ndi chinthu chachilengedwe chomwe chimapangidwa kudzera munjira za geological pazaka mazana mamiliyoni ambiri. Mapangidwe ake amkati a kristalo ndi wandiweyani komanso ofanana, ndipo ali ndi kukhazikika kwakukulu. Mzere wowonjezera wowonjezera wa granite ndi 0.5-8 × 10⁻⁶/℃, womwe ndi 1/2-1/3 wa chitsulo chosungunuka, ndipo sichikhudzidwa kwambiri ndi kusintha kwa kutentha. Pakadali pano, granite ndi yolimba mu kapangidwe kake, yokhala ndi mphamvu yopondereza mpaka ma kilogalamu 1,050-14,000 pa lalikulu centimita. Ikhoza kukana bwino mphamvu zakunja ndi kugwedezeka, kupereka maziko olimba ndi okhazikika a nsanja yoyendetsera kayendetsedwe kake. Pafupifupi palibe kupsinjika kotsalira mkati mwake, ndipo sikungabweretse kusintha kwakukulu chifukwa cha kumasuka kwa kupsinjika, kuonetsetsa kuti nsanjayo ikhale yokhazikika kuchokera kuzinthu zakuthupi. ku
Deta yoyesera imatsimikizira kusiyana kwa magwiridwe antchito
Pofuna kufananiza kusiyana kwa kukhazikika kwapakati pakati pa granite ndi chitsulo choponyedwa, gulu lofufuza lidachita kuyesa kwapadera. Mapulatifomu awiri oyendetsa makina opangira batire a lithiamu amtundu womwewo adasankhidwa, opangidwa ndi granite ndi chitsulo choponyedwa motsatana, ndikuyesedwa pansi pazikhalidwe zomwezo. Kuyeserako kunatengera zochitika zenizeni za makina opaka batire a lithiamu. Pogwiritsa ntchito zidazo mosalekeza, kusintha kwa kukula kwa nsanja pazigawo zanthawi zosiyanasiyana kumayang'aniridwa. ku
Zotsatira zoyeserera zikuwonetsa kuti pambuyo pogwira ntchito mosalekeza kwa maola a 24, chifukwa cha kutentha komwe kumapangidwa ndi zida, kutentha kwapamwamba kwa nsanja yachitsulo chachitsulo kumawonjezeka ndi pafupifupi 15 ℃, zomwe zimapangitsa kuwonjezeka kwa 0.03mm kutalika kwa nsanja. Pansi pazikhalidwe zomwezo, kukula kwa nsanja ya granite kumakhala kocheperako, ndipo kukula kwake kusinthasintha kumakhala kosakwana 0.005mm. Pambuyo pa maola a 1000 a mayesero okalamba a nthawi yayitali, chifukwa cha kutulutsidwa kwa kupsinjika kwa mkati ndi kudzikundikira kwa kutentha kwa kutentha, cholakwika cha flatness cha nsanja yachitsulo chachitsulo chinakula kuchokera ku 0.01mm yoyamba mpaka 0.05mm. Cholakwika cha flatness cha nsanja ya granite nthawi zonse chimasungidwa mkati mwa 0.015mm, ndipo ubwino wa kukhazikika kwazithunzi ndizodziwikiratu. ku
Kupambana kodabwitsa muzogwiritsa ntchito
Popanga bizinesi yayikulu yopangira batire ya lithiamu, nsanja zowongolera zachitsulo zidagwiritsidwapo kale. Pamene nthawi yogwiritsira ntchito zidazo inkawonjezeka, kulondola kwa zokutira kunatsika pang'onopang'ono, zomwe zinapangitsa kuti makulidwe osakanikirana, kusasunthika bwino kwa mapepala a electrode ya batri, ndi chiwongoladzanja chamtengo wapatali mpaka 8%. Kuti athane ndi vutoli, kampaniyo idasinthiratu nsanja zowongolera za zida zina ndi zida za granite. ku
Pambuyo m'malo, kukhazikika kwa dimensional kwa zida kwasinthidwa kwambiri. Pakupanga kwa miyezi isanu ndi umodzi, makina okutira omwe amagwiritsa ntchito nsanja ya granite nthawi zonse amasunga cholakwika cha makulidwe mkati mwa ± 2μm, ndipo chiwopsezo chazowonongeka chidatsitsidwa kwambiri mpaka 3%. Pakadali pano, popeza nsanja za granite sizifunikira kuwongolera pafupipafupi komanso kukonza bwino ngati nsanja zachitsulo, zimapulumutsa mabizinesi ndalama zambiri zokonza zida ndi nthawi yochepera chaka chilichonse, ndikuwonjezera kupanga bwino ndi kupitilira 15%. ku
Pomaliza, pogwiritsira ntchito nsanja yoyendetsera makina a lithiamu batire, granite, yokhala ndi zinthu zake zabwino kwambiri, imaposa chitsulo choponyedwa potengera kukhazikika kwazithunzi. Kaya ndi momwe zinthu zilili, deta yoyesera, kapena zotsatira zogwiritsira ntchito, granite imapereka chitsimikizo chodalirika chapamwamba kwambiri komanso kukhazikika kwa njira zopangira batire la lithiamu. Ndi kuwongolera kosalekeza kwa zofunikira zamtundu wa batire ya lithiamu, mapulatifomu owongolera opangidwa ndi granite akuyenera kukhala chisankho chodziwika bwino pamsika.
