Tlhahlobo ea Boleng ba Graphite

Kakaretso ea teko

Graphite is an allotrope of carbon, a transitional crystal between atomic crystals, metal crystals and molecular crystals.Ka kakaretso grey black, soft texture, greasy feeling.Mocheso o matlafalitsoeng moeeng kapa oksijene e tukang le ho hlahisa carbon dioxide.Strong oxidizing agents will oxidize it into E sebelisoa e le antiwear le lintho tse tlotsang, ho etsa crucible, electrode, betri e omeletseng, lead lead graphite emulsion, graphite e atolositsoeng, letsopa graphite le conductive graphite phofo, joalo-joalo.

Lintho tse khethehileng tsa graphite

1. mocheso o phahameng oa ho hanyetsa: sebaka se qhibilihisang sa graphite ke 3850 ± 50 ℃, esita le ka mor'a ho chesa mocheso o phahameng haholo oa arc, tahlehelo ea boima ba 'mele e nyenyane haholo, coefficient ea ho atolosa mocheso e nyenyane haholo.Matla a graphite a eketseha ka ho eketseha ha mocheso. . Ka 2000 ℃, matla a graphite a imena habeli.
2. conductive, conductivity ea mocheso: conductivity ea graphite e phahame ka makhetlo a lekholo ho feta ore e se nang tšepe e tloaelehileng. Thermal conductivity ea tšepe, tšepe, lead le lisebelisoa tse ling tsa tšepe. Thermal conductivity e fokotseha ka ho eketseha ha mocheso, esita le ka ho fetisisa. mocheso o phahameng, graphite ho kenya letsoho;
3. Lubricity: ts'ebetso ea lubrication ea graphite e itšetlehile ka boholo ba graphite flake, flake, friction coefficient e nyane, ts'ebetso ea lubrication e molemo;
4. botsitso ba lik'hemik'hale: graphite ka mocheso oa kamore e na le botsitso bo botle ba lik'hemik'hale, ho hanyetsa acid, ho hanyetsa alkali le ho hanyetsa ho senyeha ha lintho tsa tlhaho;
5. polasetiki: boima ba graphite bo botle, bo ka sithabetsoa ka letlapa le lesesaane haholo;
6. ho hanyetsa mocheso oa mocheso: graphite ka mocheso oa kamore ha e sebelisoa e ka mamella liphetoho tse matla tsa mocheso ntle le tšenyo, phetoho ea mocheso, molumo oa graphite o fetoha hanyenyane, o ke ke oa phunyeha.

Ea bobeli, matšoao a ho lemoha

1. tlhahlobo ea sebopeho: carbon e tsitsitseng, mongobo, litšila, joalo-joalo;
2. Teko ea ts'ebetso ea 'mele: ho thatafala, molora, viscosity, bokhabane, boholo ba likaroloana, ho feto-fetoha ha matla, matla a khoheli a itseng, sebaka se itseng sa holim'a metsi, ntlha e qhibilihang, joalo-joalo.
3. Teko ea thepa ea mochini: matla a thata, brittleness, teko ea ho khumama, teko ea ho tsitsa;
4. Teko ea ts'ebetso ea lik'hemik'hale: ho hanyetsa metsi, ho tšoarella, ho hanyetsa acid le alkali, ho hanyetsa kutu, ho hanyetsa boemo ba leholimo, ho hanyetsa mocheso, joalo-joalo.
5. Lintho tse ling tsa tlhahlobo: conductivity ea motlakase, conductivity ea mocheso, lubrication, botsitso ba lik'hemik'hale, ho hanyetsa mocheso oa mocheso.
