• Kev txawj ntse thiab txhawb nqa:Nej liGraph kaw electrodeTsum yuav tsum muaj ntau dua li tsuas yog lub chaw muag khoom nkaus xwb. Saib rau atus tsimnrog in--qhov kev paub txog kev txawj ntse. Lawv yuav tsum muaj peev xwm los tham txog koj qhov tshwj xeebFais arc rauv kev phais, nkag siab koj cov kev cov nyom (piv txwv li, siabkev noj, Breakage), thiab pom zoo kom haum haumteem nqintawmGraph kaw electrode(RP, HP, lossis UHP) los ua kom koj ua kom zoo thiabyajefficiency. Kev sib txuas lus meej yog qhov tseem ceeb, tshwj xeeb tshaj yog kom tsis txhob muaj cov ntsiab lus mob zoo li kev sib tham tsis muaj zog.
• Cov ntaub ntawv pov thawj ua pov thawj thiab kev ntseeg tau:Nrhiav cov chaw muag khoom nrog cov keeb kwm ntawm cov khoom siv zoo ib yam zoo thiab lub sijhawm. Cov khoom xa tuaj qeeb tuaj yeem ua rau lub sijhawm ua haujlwm, ib qho mob loj rau ib qhohlautsim. Nug rau cov ntawv xa los yog kev kawm tshwj xeeb, tshwj xeeb yog los ntawm cov neeg siv khoom hauv koj cheeb tsam lossis kev lag luam. Kev paub hauv kev xa tawm rau koj lub tebchaws (zoo li peb kev paub nrog Asmeskas) txhais tau tias lawv nkag siab cov logistics thiab cov txheej txheem kev lis kev cai. Koj kuj tseem yuav xav txog cov khoom zoo liCov Khoom Zoo Graphite BlocksYog tias koj cov kev xav tau txuas ntxiv dhau xwb electrodes, raws li cov khoom xa khoom tuaj yeem yog qhov zoo.
• Cov nqe lus qhia pob tshab thiab cov nqe lus them nqi:Thaum zoo yog qhov tseem ceeb, nqi yuav tsum yog kev sib tw. Nkag siab tag nrho tus nqi, suav nrog kev thauj khoom thiab txhua lub luag haujlwm. Tus neeg xa khoom zoo yuav muab cov ntsiab lus tseeb thiab qhib rau sab laj kev them nyiaj txoj kev them nyiaj uas ua haujlwm rau ob tog. Lub hom phiaj yog lub sijhawm ntev kev sib koom ua ke, tsis yog ib qho kev hloov pauv ib zaug xwb.
• Muaj peev xwm tsim tau:Tus xa khoom nrog lawv tus kheej cov kab ntau lawm, zoo li peb li, muaj kev tswj tau zoo dua thiab muab khoom sib xws. Lawv muaj feem ntau yuav nqis peev hauv R & D thiab txuas ntxiv txhim kho lawvGraph kaw electrodeCov khoom lag luam. Mus saib lub Hoobkas (yog tias ua tau) lossis muaj kev ncig xyuas virtual tuaj yeem muab cov kev pom zoo rau hauv lawv lub peev xwm thiab kev cog lus kom zoo rau txhua tuskhoom siv hluav taws xob.
