I-graphite enwetshiwe, eyaziwa nangokuthi i-flexible graphite noma i-worm graphite, iwuhlobo olusha lwe-carbon material. I-graphite eyandisiwe inezinzuzo eziningi ezifana nendawo enkulu ethize, umsebenzi ongaphezulu, ukuzinza okuhle kwamakhemikhali kanye nokumelana nokushisa okuphezulu. Inqubo evame ukusetshenziswa yokulungiselela i-graphite eyandisiwe iwukusebenzisa i-flake graphite yemvelo njengento, okokuqala ukukhiqiza i-graphite enwebekayo ngenqubo ye-oxidation, bese inweba ibe yi-graphite enwetshiwe. Abahleli abalandelayo be-Furuite Graphite bachaza ukulungiswa kanye nokusetshenziswa okungokoqobo kwegraphite enwetshiwe:
1. Indlela yokulungiselela i-graphite eyandisiwe
Iningi le-graphite eyandisiwe isebenzisa i-chemical oxidation kanye ne-electrochemical oxidation. Indlela yendabuko ye-chemical oxidation ilula ekusebenzeni futhi izinzile ngekhwalithi, kodwa kunezinkinga ezifana nokuchithwa kwesisombululo se-asidi kanye nokuqukethwe okuphezulu kwesibabule emkhiqizweni. Indlela ye-electrochemical ayisebenzisi i-oxidant, futhi isisombululo se-asidi singaphinda sisetshenziswe futhi sisetshenziswe kaningi, ngokungcoliswa kwemvelo okuncane kanye nezindleko eziphansi, kodwa isivuno sincane, futhi izidingo zezinto ze-electrode ziphakeme kakhulu. Njengamanje, ilinganiselwe ocwaningweni lwaselabhorethri. Ngaphandle kwezindlela ezihlukene ze-oxidation, ukwelashwa kwangemva kokukhipha i-acidification, ukugeza amanzi nokomisa kuyafana kulezi zindlela ezimbili. Phakathi kwazo, indlela ye-chemical oxidation iyindlela esetshenziswa kakhulu kuze kube manje, futhi ubuchwepheshe buvuthiwe futhi buye bakhuthazwa kakhulu futhi basetshenziswa embonini.
2. Izinkambu ezisebenzayo zegraphite enwetshiwe
1. Ukusetshenziswa kwezinto zokwelapha
Izingubo zezokwelapha ezenziwe nge-graphite enwetshiwe zingangena esikhundleni se-gauze yendabuko ngenxa yezakhiwo zazo ezinhle kakhulu.
2. Ukusetshenziswa kwezinto zempi
Ukuhlikihla i-graphite enwetshiwe ibe yi-micropowder kunezici ezinamandla zokuhlakazeka nokumunca zamagagasi e-infrared, futhi ukwenza i-micropowder yayo ibe yimpahla yokuvikela engaphandle kwe-infrared kudlala indima ebalulekile ekubhekaneni nge-optoelectronic ezimpini zanamuhla.
3. Ukusetshenziswa kwezinto zokuvikela imvelo
Ngenxa yokuthi i-graphite eyandisiwe inezici zokuminyana okuphansi, okungeyona ubuthi, okungangcolisi, ukuphatha kalula, njll., futhi ine-adsorption enhle kakhulu, inohlu olubanzi lwezinhlelo zokusebenza emkhakheni wokuvikelwa kwemvelo.
4. Izinto ze-Biomedical
Izinto zekhabhoni zinokuhambisana okuhle kakhulu nomzimba womuntu futhi ziyinto enhle ye-biomedical. Njengohlobo olusha lwe-carbon material, izinto ezinwetshiwe ze-graphite zinezakhiwo ezinhle kakhulu zokukhangisa zama-macromolecules ephilayo nawe-biological, futhi zinokuhambisana okuhle kwe-biocompatibility. , non-toxic, ayinambitheki, akukho side effects, has anhlobonhlobo amathemba isicelo ku-biomedical materials.
Izinto ezinwetshiwe zegraphite zinganwebeka ngokushesha izikhathi eziyi-150 ~ 300 ngevolumu lapho zichayeka ekushiseni okuphezulu, zishintsha ukusuka ku-flake kuye njenge-worm, okuholela ekwakhiweni okuxekethile, okunezimbobo nokugobile, indawo engaphezulu enwetshiwe, amandla angaphezulu athuthukisiwe, kanye nekhono elithuthukisiwe lokukhangisa. i-flake graphite. I-graphite efana ne-worm ingakwazi ukuzimela ngokwayo, ukuze izinto zibe nemisebenzi yokubuyiswa komlilo, ukuvala uphawu, i-adsorption, njll., futhi inohlu olubanzi lwezinhlelo zokusebenza emkhakheni wezempilo, ezempi, ukuvikelwa kwemvelo, kanye nemboni yamakhemikhali. .
