Madhaimani uyegraphiteimhando mbiri dzakasiyana dzekabhoni dzakatora fungidziro dzedu kwemazana emakore. Pamusoro pechitarisiko chavo chinoshamisa uye akasiyana maindasitiri ekushandisa, izvi zvinhu zvine zvinhu zvinonakidza zvinozvisiyanisa kubva kune mumwe nemumwe. Chimwe chezvinhu izvi inzvimbo yavo yekunyungudika. Mune ino blog post, isu'Ichapinda munyika inonakidza yedhaimani uye graphite, ichiongorora izvo zvinopesvedzera nzvimbo dzadzo dzekunyungudika uye kuratidza yavo yakasarudzika.
Diamond inonyungudika:
Madhaimani anowanzo kunzi mambo wematombo anokosha uye anozivikanwa nekuoma kwawo uye kupenya kwakanaka. Nekudaro, kana zvasvika pakunyungudika, madhaimondi anoratidza kusinganzwisisike kupisa kupisa. Kufanana nekupenya kwayo kunokatyamadza, chimiro chemamorekuru edhaimondi chinoita basa rakakosha pakuona pakakwirira kunyungudika.
Chimiro chedhaimondi chine maatomu ecarbon akarongwa mutetrahedral pateni. Iyi network yakasimba ine mativi matatu haisi nyore kuputsika, ichipa madhaimondi nzvimbo yakanyanyisa kunyungudika. Dhaimondi rinodzivirira kupisa zvisingaite, iine nzvimbo yekunyunguduka inosvika 3,550 degrees Celsius (6,372 degrees Fahrenheit). Nekunyungudika uku, dhaimondi rinogona kumira kutonhora kwakanyanya, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekushanda kwemaindasitiri, zvakadai sematurusi ekucheka uye nzvimbo dzepamusoro-soro.
Kunyungudika kwegraphite:
Mukusiyana zvakanyanya nedhaimani, graphite ine chimiro chakasiyana chose chemolecular, zvichikonzera kunyungudika kwakadzikira. Graphite ine zvikamu zvekabhoni maatomu akarongwa ane hexagonal pateni, achigadzira nhevedzano yemaflakes akaturikidzana. Mashizha anobatwa pamwe chete neasina simba intermolecular masimba, zvichiita kuti zvive nyore kukanganisa iyo latisi chimiro kana ichipisa.
Graphite's molecular chimiro inopa yakanakisa magetsi conductivity uye ine mafuta ekuzora nekuda kwekutsvedza kwemaitiro ayo. Zvisinei, graphite nedhaimani zvine nzvimbo dzakaderera dzekunyungudika. Graphite ine nzvimbo yekunyunguduka inosvika 3,500 madhigirii celsius (6,332 madhigirii Fahrenheit) uye ine kushomeka kwekupisa kana zvichienzaniswa nedhaimondi.
Nei musiyano uyu unokosha:
Kunzwisisa kunyunguduka kwedhaimondi uye graphite kwakakosha nekuda kwezvikonzero zvakati. Kubva pakuona kwesainzi, inoratidza kuti kabhoni inoratidza zvakasiyana-siyana zvemuviri zvimiro zvinoenderana nekurongeka kwayo padanho remamorekuru. Pamusoro pezvo, indasitiri inogona kushandisa ruzivo urwu kusarudza yakakodzera fomu yekabhoni kune chaiyo maapplication, nekudaro ichiwedzera kugona uye kuita.
Kunyange zvazvo dhaimani negirafu zviine nzvimbo dziri pedyo dzekunyunguduka, misimboti yadzo yakasiyana-siyana uye zvimiro zvinokonzeresa zvinopa mikana yakasiyana yekushandiswa kwayo. Kunyungudika kwedhaimani kwakakwirira kunoita kuti ive yakakosha munzvimbo dzakaoma, nepo nzvimbo yakaderera yegraphite inonyungudika ichisimudzira kukodzera kwayo mumashandisirwo anoda kufambiswa kwemagetsi nekuzora.
In mhedziso:
Muchidimbu, kunyungudika kwedhaimondi uye graphite chinhu chinonakidza cheaya anoshamisa mafomu ecarbon. Musiyano unova pachena nekuti dhaimani rine nzvimbo yakanyanyisa kunyungudika nepo graphite iine nzvimbo yakaderera yekunyungudika. Iwo akasiyana mamorekuru zvimiro zveaya kabhoni makunakuna.vape zvivakwa zvakasiyana uye uvaite chinhu chakakosha chekushandisa kune akasiyana maindasitiri. Nekunzwisisa iwo nuances ari kuseri kwenzvimbo dzawo dzakanyunguduka, tinogona kudzidza zvakawanda nezve inoshamisa nyika yedhaimondi uye graphite, nekusingaperi tichiwedzera kukoshesa kwedu hunhu hwavo hwakasiyana.
