Txhab graphite, tseem hu ua hloov cov duab graphite lossis cov cab cab, yog cov khoom siv roj carbon ntau tshiab. Kev nthuav dav graphite muaj ntau qhov zoo xws li thaj chaw loj thaj chaw loj, kev ua si siab, tshuaj lom neeg zoo thiab kub ua tsis taus. Cov txheej txheem npaj tau tshwm sim ntawm cov graphite nthuav dav yog siv cov pa hluav taws xob yooj yim raws li cov ntaub ntawv nthuav tawm los ntawm cov txheej txheem oxidation, thiab tom qab ntawd los nthuav mus ua kev nthuav dav graphite. Cov qauv hauv qab no ntawm cov plualuite graphite piav qhia txog kev npaj thiab cov ntaub ntawv thov ntawm nthuav graphite:
1. Kev npaj txoj kev ntawm nthuav graphite
Feem ntau ntawm cov kev hloov kho graphite oliidation thiab electrofochemical oxidation. Cov qauv tshuaj oxidation yog qhov yooj yim hauv cov txheej txheem thiab ruaj khov hauv qhov zoo, tab sis muaj cov teeb meem ntawm cov kua qaub thiab cov neeg sawv cev ntawm cov khoom lag luam siab hauv cov khoom. Cov qauv electrochemical tsis siv cov oxidant, thiab siv cov pa phem ntau zaus, tab sis cov txiaj ntsig ib puag ncig, tab sis cov kev xav tau rau cov khoom electrode yog qhov siab. Tam sim no, nws yog txwv rau kev tshawb nrhiav kev kuaj. Tsuas yog cov txheej txheem oxidation sib txawv, cov tom qab kev kho mob xws li kev ua plaub ntug, dej ntxuav thiab qhuav yog tib yam rau ob txoj kev no. Ntawm lawv, cov tshuaj oxidation oxidation yog cov kev siv thev naus laus zis ntau dhau mus kom deb li deb, thiab muaj kev paub tab thiab tau tshaj tawm dav thiab thov hauv kev lag luam.
2. Cov ntaub ntawv thov ntawm cov teb uas nthuav dav graphite
1. Daim ntawv thov ntawm cov ntaub ntawv kho mob
Kev hnav khaub ncaws kho mob ua los ntawm kev nthuav qhia graphite tuaj yeem hloov cov ntaub ntawv ib txwm muaj vim lawv cov khoom zoo tshaj plaws.
2. Daim ntawv thov ntawm cov ntaub ntawv tub rog
Pulverizing Graphite rau hauv micropowder muaj cov khoom siv thaiv tsis tau rau infrared lub luag haujlwm hauv kev tawm tsam valve hauv kev ua rog niaj hnub no.
3. Daim ntawv thov ntawm cov ntaub ntawv tiv thaiv ib puag ncig
Vim tias kev nthuav dav graphite muaj cov yam ntxwv ntawm qhov tsis tshua muaj zog, tsis muaj tshuaj lom, thiab muaj kuab lom, thiab muaj ntau yam kev siv tshuaj tiv thaiv kev tiv thaiv ib puag ncig.
4. Biomedical cov ntaub ntawv
Cov ntaub ntawv carbon muaj cov khoom siv tau zoo heev nrog tib neeg lub cev thiab yog cov khoom siv biomedical zoo. Raws li hom tshiab ntawm cov khoom siv carbon, nthuav qhia cov duab graphite muaj adstorption zoo tshaj plaws rau cov organic thiab roj macromolecules, thiab muaj cov zoo biocompatibility. , tsis-toxic, tsis muaj kev mob, tsis muaj kev phiv, muaj ntau yam kev thov kev cia siab hauv cov ntaub ntawv biomedical.
Cov ntaub ntawv txuas tau yooj yim tuaj yeem nthuav dav 150 ~ 300 lub sij hawm nyob rau hauv cov qauv sib xyaw, txhim kho lub zog saum npoo av, thiab txhim kho lub peev xwm saum npoo av, thiab txhim kho kev muaj peev xwm tawm ntawm lub zog. Tus cab zoo li graphite tuaj yeem ua rau nws tus kheej, yog li cov khoom siv ntawm cov kab mob hauv lub neej, kev tiv thaiv kev ua tub rog, kev tiv thaiv ib puag ncig, thiab kev lag luam ib puag ncig, thiab kev lag luam ib puag ncig, thiab kev lag luam ib puag ncig, thiab kev lag luam ib puag ncig, thiab kev lag luam ib puag ncig, thiab kev lag luam ib puag ncig, thiab kev lag luam ib puag ncig, thiab kev lag luam ib puag ncig.
