Yazisa:
Iidayimani kunyeigraphiteziindidi ezimbini ezahlukeneyo zekhabhoni ezithathe iingqikelelo zethu kangangeenkulungwane.Ukongeza kwinkangeleko yabo emangalisayo kunye neentlobo ezahlukeneyo zokusebenza kwemizi-mveliso, ezi zinto zineempawu ezinomdla ezibenza bahluke omnye komnye.Enye yezi mpawu yindawo yazo yokunyibilika.Kule post blog, thina'Baza kuphonononga kwihlabathi elinomdla ledayimane kunye negraphite, bajonge izinto eziphembelela iindawo zabo zokunyibilika kunye nokutyhila iimpawu zabo ezizodwa.
Indawo yokunyibilika kwedayimani:
Iidayimani zihlala zibizwa ngokuba yinkosi yamatye anqabileyo kwaye ziyaziwa ngokuba lukhuni kunye nokucwebezela okuhle.Nangona kunjalo, xa kuziwa kwiindawo zokunyibilika, iidayimani zibonisa ukuxhathisa ubushushu obungaqhelekanga.Njengobukhazikhazi bayo obumangalisayo, ulwakhiwo lwemolekyuli yedayimane idlala indima ebalulekileyo ekumiseleni indawo yayo ephezulu yokunyibilika.
Ulwakhiwo lweletisi yeDayimane luqulathe iiathom zekhabhoni ezicwangciswe ngokwepateni yetetrahedral.Lo mnatha womelele unamacala amathathu akophukanga lula, unika idayimani indawo yokunyibilika ephezulu ngokungaqhelekanga.Idayimani iyamelana nobushushu ngendlela emangalisayo, kwaye iqondo lokunyibilika elimalunga ne-3,550 degrees Celsius (6,372 degrees Fahrenheit).Ngeli nqanaba lokunyibilika, idayimane inokumelana nokushisa okugqithisileyo, okwenza kube yinto efanelekileyo kwizicelo ezahlukeneyo zoshishino, ezifana nezixhobo zokusika kunye neendawo eziphezulu zokushisa.
Indawo yokunyibilika yegraphite:
Ngokwahlukileyo kwidayimani, igraphite inemolekyuli eyahluke ngokupheleleyo, nto leyo ebangela ukuba iqondo lokunyibilika lisezantsi kakhulu.Igraphite iqulathe umaleko weeathom zekhabhoni ezicwangciswe ngokwepateni enehexagonal, zenza uthotho lweeflakes ezipakishweyo.Amaphepha abanjwe kunye ne-intermolecular forces ebuthakathaka, okwenza kube lula ukuphazamisa isakhiwo se-lattice xa sishushu.
Ulwakhiwo lwemolekyuli yegraphite inika umbane ogqwesileyo kwaye ineempawu zokuthambisa ngenxa yokutyibilika kweeleya zayo.Nangona kunjalo, igraphite nedayimani zineendawo ezisezantsi zokunyibilika.Igraphite inendawo yokunyibilika emalunga ne-3,500 degrees celcius (6,332 degrees Fahrenheit) kwaye inokumelana nobushushu obuphantsi xa kuthelekiswa nedayimani.
Kutheni lo mahluko ubalulekile:
Ukuqonda iindawo ezinyibilikayo zedayimane kunye negraphite kubalulekile ngenxa yezizathu ezininzi.Ukusuka kwimbono yesayensi, ibonisa ukuba ikhabhoni ibonisa iintlobo ezahlukeneyo zezinto eziphathekayo ngokusekelwe kwilungiselelo layo kwinqanaba le-molecular.Ukongezelela, ishishini linokusebenzisa olu lwazi ukukhetha uhlobo olufanelekileyo lwekhabhoni kwizicelo ezithile, ngaloo ndlela ukwandisa ukusebenza kakuhle kunye nokusebenza.
Nangona idayimani kunye negraphite zineendawo ezisondele kakhulu zokunyibilika, ulwakhiwo lwazo lweemolekyuli ezahlukeneyo kunye neempawu eziphumayo zibonelela ngeendlela ezahlukeneyo zokusebenzisa kwazo.Iqondo lokunyibilika eliphezulu leDayimane liyenza ixabiseke kakhulu kwiindawo ezirhabaxa, ngelixa indawo esezantsi yokunyibilika yegraphite iphucula ukufaneleka kwayo kwizicelo ezifuna ukuhanjiswa kombane kunye nokuthambisa.
In isiphelo:
Isishwankathelo, iindawo ezinyibilikayo zedayimane kunye negraphite ziyinkalo enomdla kwezi ndlela zingaqhelekanga zekhabhoni.Umahluko uyabonakala kuba idayimani inendawo yokunyibilika ephezulu kakhulu ngelixa igraphite inendawo esezantsi yokunyibilika.Izakhiwo ezahlukeneyo zemolekyuli zabazala bekhabhoni.ubanike iipropathi ezizodwa kwaye ubenze babe sisixhobo esixabisekileyo kumashishini ahlukeneyo.Ngokuqonda ama-nuances asemva kwamanqaku azo anyibilikayo, sinokufunda ngakumbi malunga nehlabathi elingaqhelekanga ledayimane kunye negraphite, sikhulisa uxabiso lwethu ngeempawu zabo ezizodwa.
