Graphite muab faib ua ntuj graphite thiab hluavtaws graphite. Cov neeg feem coob paub tab sis tsis paub yuav ua li cas cais lawv. Dab tsi yog qhov txawv ntawm lawv? Tus editor hauv qab no yuav qhia koj paub qhov txawv ntawm ob:
1. Crystal qauv
Ntuj graphite: Cov siv lead ua kev loj hlob kuj ua tiav, qib ntawm graphitization ntawm flake graphite yog ntau dua 98%, thiab qib ntawm graphitization ntawm ntuj microcrystalline graphite feem ntau yog qis dua 93%.
Artificial graphite: Lub degree ntawm siv lead ua kev loj hlob nyob ntawm cov khoom siv raw thiab kev kho cua sov. Feem ntau hais lus, qhov siab dua qhov kev kho cua sov, qhov siab dua ntawm graphitization. Tam sim no, cov degree ntawm graphitization ntawm cov khoom graphite tsim nyob rau hauv kev lag luam feem ntau yog tsawg dua 90%.
2. Lub koom haum qauv
Ntuj flake graphite: Nws yog ib qho siv lead ua uas muaj cov qauv yooj yim thiab tsuas yog muaj qhov tsis xws luag crystallographic (xws li qhov tsis xws luag, dislocations, stacking faults, thiab lwm yam), thiab nthuav tawm cov yam ntxwv anisotropic ntawm qib macroscopic. Cov nplej ntawm tej yam ntuj tso microcrystalline graphite yog me me, cov nplej yog cov txheej txheem tsis zoo, thiab muaj qhov pores tom qab cov impurities raug tshem tawm, qhia isotropy ntawm qib macroscopic.
Artificial graphite: Nws tuaj yeem suav tias yog cov khoom siv ntau theem, suav nrog graphite theem hloov los ntawm carbonaceous hais xws li roj av coke lossis pitch coke, graphite theem hloov los ntawm thee tar binder qhwv ib ncig ntawm cov khoom, particle accumululation lossis thee tar pitch. Cov pores tsim los ntawm cov binder tom qab kev kho cua sov, thiab lwm yam.
3. Daim ntawv lub cev
Ntuj graphite: feem ntau muaj nyob rau hauv daim ntawv ntawm cov hmoov thiab siv tau ib leeg, tab sis nws yog feem ntau yog siv ua ke nrog lwm yam ntaub ntawv.
Artificial graphite: Muaj ntau ntau hom, nrog rau cov hmoov, fiber ntau thiab thaiv, thaum cov khoom siv graphite nyob rau hauv qhov kev nkag siab nqaim feem ntau yog thaiv, uas yuav tsum tau ua tiav rau hauv ib qho duab thaum siv.
4. Lub cev thiab tshuaj muaj zog
Nyob rau hauv cov nqe lus ntawm lub cev thiab tshuaj zog, ntuj graphite thiab dag graphite muaj ob qho tib si thiab sib txawv ntawm kev ua tau zoo. Piv txwv li, ob qho tib si ntuj graphite thiab dag graphite yog cov zoo conductors ntawm tshav kub thiab hluav taws xob, tab sis rau graphite hmoov ntawm tib purity thiab particle loj, ntuj flake graphite muaj qhov zoo tshaj plaws tshav kub hloov kev kawm thiab hluav taws xob conductivity, ua raws li ntuj microcrystalline graphite thiab dag graphite. . qis tshaj. Graphite muaj lubricity zoo thiab qee yam yas. Cov siv lead ua kev loj hlob ntawm ntuj flake graphite yog qhov ua tiav, kev sib txhuam coefficient me me, lubricity yog qhov zoo tshaj plaws, thiab cov yas yog siab tshaj, ua raws li ntom crystalline graphite thiab cryptocrystalline graphite, ua raws li cov khoom siv graphite. pluag.
Qingdao Furuite Graphite feem ntau koom nrog cov ntshiab ntuj graphite hmoov, graphite ntawv, graphite mis nyuj thiab lwm yam khoom graphite. Lub tuam txhab muab qhov tseem ceeb heev rau credit los xyuas kom meej cov khoom zoo. Cov neeg muas zaub zoo siab txais tos hu rau peb.
