Expanded graphite, tseem hu ua saj zawg zog graphite los yog worm graphite, yog ib hom tshiab ntawm cov khoom siv carbon. Expanded graphite muaj ntau yam zoo xws li thaj chaw loj tshwj xeeb, kev ua haujlwm siab, tshuaj lom neeg ruaj khov thiab kub tsis kam. Cov txheej txheem kev npaj siv feem ntau ntawm nthuav graphite yog siv cov flake graphite ua cov khoom siv, ua ntej los tsim cov graphite nthuav dav los ntawm cov txheej txheem oxidation, thiab tom qab ntawd kom nthuav dav hauv graphite. Cov nram qab no editors ntawm Furuite Graphite piav qhia txog kev npaj thiab siv tswv yim ntawm nthuav graphite:
1. Txoj kev npaj ntawm nthuav graphite
Feem ntau ntawm cov graphite nthuav dav siv tshuaj oxidation thiab electrochemical oxidation. Cov txheej txheem tshuaj oxidation ib txwm yog yooj yim hauv cov txheej txheem thiab ruaj khov hauv qhov zoo, tab sis muaj teeb meem xws li pov tseg cov kua qaub thiab cov ntsiab lus sulfur siab hauv cov khoom. Cov txheej txheem electrochemical tsis siv cov oxidant, thiab cov kua qaub tuaj yeem rov ua dua thiab rov siv tau ntau zaus, nrog rau kev ua qias tuaj ib puag ncig thiab tus nqi qis, tab sis cov txiaj ntsig qis, thiab cov kev xav tau ntawm cov khoom siv electrode kuj siab heev. Tam sim no, nws tsuas yog txwv rau kev tshawb fawb hauv chav kuaj. Tsuas yog rau txoj kev sib txawv oxidation, cov kev kho mob tom qab xws li deacidification, dej ntxuav thiab ziab yog tib yam rau ob txoj kev no. Ntawm lawv, cov tshuaj oxidation txoj kev yog txoj kev siv dav tshaj plaws kom deb li deb, thiab cov cuab yeej siv tau zoo thiab tau txais kev txhawb nqa thiab siv hauv kev lag luam.
2. Kev siv tswv yim teb ntawm nthuav graphite
1. Kev siv cov ntaub ntawv kho mob
Kev hnav khaub ncaws kho mob ua los ntawm kev nthuav dav graphite tuaj yeem hloov cov ntaub qhwv ib txwm siv vim lawv cov khoom zoo heev.
2. Kev siv cov khoom siv tub rog
Pulverizing nthuav graphite rau hauv micropowder muaj zog tawg thiab nqus cov khoom rau infrared nthwv dej, thiab ua rau nws cov micropowder rau hauv ib qho zoo heev infrared shielding khoom plays lub luag haujlwm tseem ceeb hauv optoelectronic confrontation hauv kev ua tsov rog niaj hnub no.
3. Kev siv 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 kev sib raug zoo nrog tib neeg lub cev thiab yog cov khoom siv biomedical zoo. Raws li hom tshiab ntawm cov khoom siv carbon, nthuav cov ntaub ntawv graphite muaj cov khoom zoo adsorption rau cov organic thiab lom macromolecules, thiab muaj biocompatibility zoo. , non-toxic, tasteless, tsis muaj kev phiv, muaj ntau yam ntawm daim ntawv thov kev cia siab nyob rau hauv biomedical cov ntaub ntawv.
Cov khoom siv graphite nthuav dav tuaj yeem nthuav dav 150 ~ 300 npaug ntawm qhov ntim thaum raug kub, hloov los ntawm flake mus rau worm-zoo li, ua rau cov qauv xoob, ntxeem tau thiab nkhaus, qhov loj ntawm qhov chaw, txhim kho lub zog saum npoo, thiab txhim kho lub peev xwm adsorb. flake graphite. Cov worm-zoo li graphite tuaj yeem ua rau nws tus kheej, yog li cov khoom siv muaj lub luag haujlwm ntawm nplaim hluav taws, sealing, adsorption, thiab lwm yam, thiab muaj ntau yam kev siv hauv kev ua neej, kev ua tub rog, kev tiv thaiv ib puag ncig, thiab kev lag luam tshuaj lom neeg. .
