I-Nano Graphene Powder CAS 1034343-98-0 Intengo Yemboni Yebanga Lebhethri
Incazelo Yomkhiqizo
I-Graphene oxide inenani elikhulu lamaqembu aqukethe umoya-mpilo ebusweni bayo. Inomswakama omuhle kanye nokusondelana nama-polymer. Okuqukethwe komoya-mpilo eqenjini lomoya-mpilo kungu-30-40%, ukuncibilika kwamanzi kuhle kakhulu, kanti okuqukethwe kwe-monolayer ngemva kokuncibilika kungaphezu kuka-99%. Ubukhulu kanye nobukhulu be-microchip busukela ku-0.5 kuya ku-3 um kanye no-0.55 kuya ku-1.2 nm. Akukho mvula.
Impuphu ye-Graphene oxide itholakala ngokumisa nge-vacuum freeze ye-graphene oxide sol. Ngesikhathi sokumisa nge-freeze, i-graphene oxide ngeke ilahlekelwe amaqembu aqukethe umoya-mpilo ebusweni futhi ibangele ukufana phakathi kwezingqimba ze-graphene oxide. Impuphu ngemva kokomisa inezimbobo futhi ifana ne-spongy. Incibilika ngokushesha nangokuphelele ngemva kokufaka amanzi, futhi cishe ngokushesha ibuyisela izakhiwo zokuqala ze-sol.
Impuphu ye-graphene oxide ingasakazwa ngqo kwisisombululo samanzi kanye ne-solvent (i-ultrasound ingcono) ukuze kutholakale isisombululo sokusakazwa esifanayo nesizinzile (bheka umhlahlandlela wokusakazwa wendlela ethile yokusakazwa).

Isicelo
I-Graphene iwuhlobo lwe-carbon nanomaterial olunezinhlangothi ezimbili olune-honeycomb lattice enezinhlangothi eziyisithupha eyakhiwe ama-athomu e-carbon kanye nama-orbital e-sp² hybrid.
I-Graphene inezakhiwo ezinhle kakhulu zokukhanya, zikagesi, kanye nezemishini, futhi inamathuba abalulekile okusetshenziswa kwisayensi yezinto zokwakha, ukucubungula i-micro-nano, amandla, i-biomedicine, kanye nokulethwa kwemithi. Ibhekwa njengento entsha esikhathini esizayo.
Izindlela ezivamile zokukhiqiza impuphu ye-graphene indlela yokuhluba ngomshini, indlela ye-redox, indlela yokukhula kwe-SiC epitaxial, kanye nendlela yokukhiqiza ifilimu encane i-chemical vapor deposition (CVD).
Ukupakisha Nokugcina Izinto
Ukupakisha: 10g /100g/ 1kg/ ngebhodlela ngalinye
Izingubo zokuzivikela ezifanele kanye namagilavu okuphepha kufanele agqokwe ukuze kuvinjelwe ukuthintana ngqo nomzimba womuntu. Uma kwenzeka ukuthintana, kudingeka ukuhlanza ngokushesha ngamanzi amaningi. Kufanele kuthathwe izinyathelo zokucubungula ezanele ukuvimbela ukukhiqizwa kothuli. Qinisekisa ukuthi umoya ungena kahle futhi ufake abaqoqi bothuli ukuze ugweme ukuhogela. Qaphela ngesikhathi sokulayisha nokukhipha impahla ukuze uvikele ekulimaleni kwephakeji.
Umkhiqizo kufanele ugcinwe ezitsheni ezivalwe kahle endaweni eyomile, epholile, futhi enomoya omuhle, ugcine ibanga eliphephile emithonjeni yokushisa nokushisa. Kumele uhlukaniswe nezinto ezinciphisa amandla nezinto ezivuthayo. Qinisekisa ukuthi amaphakheji aphelele futhi awavuzi. Uma iphakheji selivuliwe, umkhiqizo kufanele usetshenziswe ngokushesha. Amaphakheji asetshenziswe kancane kumele aphinde avalwe kahle. Umkhiqizo uyazwela emswakama. Uma umkhiqizo umunca umswakama, kungakhathaliseki ukuthi kungenxa yomonakalo wephakheji noma indawo yokugcina evulekile, kunconywa ukuthi, ngemva kokususa iphakheji yangaphandle (ngaphandle kwephakethe le-valve lephepha), umkhiqizo womiswe ku-80°C amahora amaningana uze ufinyelele esimweni sokungabi nomswakama.
Ngaphansi kwezimo zokupakisha nezokuthutha okukhulunywe ngazo ngenhla, lo mkhiqizo uhlala usebenza isikhathi eside. Uma kunezidingo eziqinile mayelana nokuqukethwe komswakama, kungcono ukomisa ngokuhambisana ne-Athikili 5 ngaphambi kokusebenzisa.
EZOKUTHUTHA
Izimpahla ezingavinjelwe. Zivikele elangeni, emvuleni, ekuvuzeni kanye namalebula ahlukanisiwe. Azivunyelwe ukuphonswa. Ziphathe ngokucophelela ngesikhathi sokulayisha nokukhipha impahla ukuze uvimbele umonakalo. Zigcine kude nemithombo yokushisa nokushisa. Akufanele zithuthwe kanye nezinto ezibolayo.
