Isiphumo kunye nenzuzo yezinto eziphathekayo zeemveliso zegraphite

Ngenxa yeepropathi zayo ezininzi ezibalaseleyo, igraphite ifumana ukusetyenziswa okubanzi kwi-metallurgical, mechanical, electronic, chemical, textile, kunye namanye amacandelo oshishino. Isebenza njengento ephikisayo kwaye igcina iimpawu zokuqala zekhemikhali ze-flake yegraphite ngelixa ibonisa iipropati ezomeleleyo zokuzithambisa. Umgubo wegraphite ubonakaliswa ngamandla aphezulu okumelana ne-asidi, ukuxhathisa ukubola, ukunyamezela ubushushu obuphezulu ukuya kuthi ga kwi-3000 ℃ kunye nokuqina okuphantsi kobushushu ukuya kuthi ga kwi -204℃. Ukongeza, iqhayisa amandla acinezelayo angaphezu kwe-800kg / Cm2 kwaye ibonisa ukuxhathisa kwe-oxidation kunye ne-1% kuphela yokulahlekelwa ubunzima xa ibonakaliswe emoyeni kwi-450 ℃. Ngaphezu koko, ibonisa izinga lokuphindaphinda kwe-15-50% (ubuninzi be-1.1-1.5). Ngenxa yoko, iimveliso zegraphite zisetyenziswa kakhulu kwisinyithi, kwishishini lekhemikhali, kwishishini lepetrochemical, i-physics yamandla aphezulu, i-aerospace, i-elektroniki kunye nezinye iinkalo ezahlukeneyo.

Iimveliso zegraphite ngokwazo zineenzuzo ezinkulu kakhulu:

1, iimveliso zegraphite zine-adsorption elungileyo.

Ulwakhiwo olungenanto lwekhabhoni lwenza ukuba ikhabhoni ibe ne-adsorption elungileyo, ngoko ke ikharbhoni isoloko isetyenziswa njengesixhobo sokubhengeza ukufunxa amanzi, ivumba, izinto ezinobuthi njalo njalo. Senze imifuniselo, kwiintsuku ezimbalwa ezidlulileyo i-barbecue esetyenzisiweyo ye-graphite yokubhaka itreyi ibonakala icoceke kakhulu, kodwa faka isifudumezi se-oveni yokungenisa, uya kubona i-barbecue yokugqibela ye-adsorption yegrisi kunye nezinto ezinobungozi ziya kuphuma kancinci, kodwa ungakhathazeki, nge iphepha lokutya elicocekileyo lokusula linokusetyenziswa.

I-2, iimveliso zegraphite zinokusebenza kakuhle kwe-thermal, ukuhanjiswa kobushushu okukhawulezayo, ubushushu obufanayo, ukonga amafutha.

Amaphepha okubhaka kunye neepani ezenziwe ngegraphite zifudumala ngokukhawuleza, kwaye ukutya okutshiswayo kushushu ngokulinganayo, kuphekwe ngaphakathi, kwaye ixesha lokufudumeza lifutshane, kungekhona nje incasa ecocekileyo, kodwa kunye nezondlo zokuqala zokutya zingavalelwa. . Senze iimvavanyo, xa i-grill pan ye-graphite isetyenziselwa ukuqhotsa, i-cooker induction ibetha umlilo ekuqaleni, kwaye inokufudumala kwimizuzwana engama-20 ukuya kwe-30 kuphela, kwaye xa ukutya kuqalisiwe, kunokudlalwa. umlilo omncinci, onokugcina amandla.

I-3, iimveliso zegraphite zinokuzinza kweekhemikhali kunye nokumelana nokubola.

I-graphite inozinzo oluhle lweekhemikhali kwiqondo lokushisa lokushisa kwaye ayihlaselwa nayiphi na i-asidi eqinile, isiseko esinamandla kunye ne-solvent ye-organic. Ngoko ke, nokuba ukusetyenziswa kwexesha elide leemveliso zegraphite ilahleko encinane kakhulu, nje ukuba kusulwe icocekile njengoko entsha.

Iimveliso ze-graphite ezi-4 zine-anti-oxidation eqinile kunye nefuthe lokunciphisa.

Iimveliso, ngakumbi i-graphite yokufudumala i-mattress inokuvelisa i-oxygen ions engalunganga, yenza izinto ezijikelezayo zisebenze, zigcine impilo yabantu, zithintele ngokufanelekileyo ukuguga, zenze ulusu luzele luster kunye nokuqina.

5, iimveliso zegraphite impilo yokusingqongileyo, akukho ungcoliseko radioactive, ukumelana lobushushu eliphezulu.

Ikhabhoni inokuba yigraphite emva kobuncinci beentsuku ezilishumi nobusuku begraphitization kwindawo yobushushu obuphezulu obungama-2000-3300 degrees, ngoko ke izinto eziyityhefu neziyingozi kwigraphite kudala zikhutshiwe kwaye zizinzile ngaphakathi kobuncinci bama-2000 degrees.

Kwangaxeshanye, iimveliso zegraphite ngenxa yesakhiwo sayo esikhethekileyo, kunye nokumelana nobushushu obuphezulu, ukuxhathisa ukothuka kwe-thermal, ukuhanjiswa kombane, ukuthambisa, ukuzinza kweekhemikhali kunye neplastikhi kunye nezinye iimpawu ezininzi, ibe sisixhobo esibalulekileyo sobuchule kuphuhliso lomkhosi kunye neshishini langoku. kunye nobuchwepheshe obuphezulu, obutsha nobubukhali, iimveliso zegraphite, ezifana nezangqa zegraphite, izikhephe zegraphite zisetyenziswa kakhulu. Iingcali zamazwe ngamazwe ziye zaqikelela ukuba "inkulungwane yama-20 yinkulungwane ye-silicon, inkulungwane yama-21 iya kuba yinkulungwane yekhabhoni."

Njengobuchule obubalulekileyo bemveliso yezimbiwa ezingezizo ezentsimbi, ishishini legraphite liya kuphunyezwa ulawulo lokufikelela. Ngokuphunyezwa kwenkqubo yokufikelela, i-graphite, iimveliso zegraphite, ziya kuba ngomnye emva komhlaba onqabileyo, ikhemikhali ye-fluorine, ikhemikhali ye-phosphorus, iinkampani ezihamba phambili kule ntsimi ziya kungena kwinqanaba elitsha lophuhliso.
