Nodular cam khwb cia hlau casting txheej txheem yog siv cov txheej txheem nodular casting, nodular cam khwb cia hlau kuj tseem nyiam hlau, los ntawm cov txheej txheem xws li kev kho cua sov los txhim kho kev ua haujlwm. Nodular cam khwb cia hlau nyob rau hauv lub tsim ntawm molten hlau nyob rau hauv tus txheej txheem ntawm graphite spheroid, tab sis kuj vim hais tias ntawm spherical graphite, thiaj li hais tias nodular cam khwb cia hlau muaj ntau yam zoo. Cov nram qab no me me ntawm Furuite graphite cov ntsiab lus yuav ua li cas spherical graphite tsim:
Spherical graphite
Spherical graphite nyob rau hauv kev tsim cov txheej txheem los ntawm ob theem, thawj yog graphite nucleation, molten hlau nyob rau hauv cov txheej txheem ntawm melting rau hauv cov kua, muaj ntau yam tsis-hlau thiab ib co impurities nyob rau hauv tus txheej txheem ntawm ua luam dej, kev sib tsoo, thiab thaum kawg yuav. muab sib sau ua ke los ua graphite pob nucleus. Tom qab cov graphite nucleates, ntau cov pa roj carbon atoms pib sau rau saum cov graphite core. Raws li ntau thiab ntau carbon atoms accumulates, lawv nws thiaj li ua kheej kheej. Qhov no yog txoj kev loj hlob thib ob ntawm kheej kheej graphite. Yog li ntawd, kom tau txais spherical graphite nyob rau hauv cov txheej txheem casting, kev tswj ntawm graphite nyob rau hauv txoj kev loj hlob yog ib qho tseem ceeb heev.
Furuite graphite kev tshawb fawb pom tias spherical graphite muaj tus nqi siab thiab tso tawm muaj peev xwm thiab electrochemical stability, yog ib qho zoo tagnrho lithium roj teeb anode cov ntaub ntawv thiab cov khoom tseem ceeb ultra siab capacitor, nrog kev ua haujlwm siab-rau-tus nqi piv. Nyob rau tib lub sijhawm, nws muaj cov khoom siv hluav taws xob zoo heev thiab cov tshuaj lom neeg ruaj khov, muaj peev xwm ua tau siab thiab tso tawm, lub neej ntev, kev tiv thaiv ib puag ncig ntsuab.
