Molamu oa Graphite oa Sechaena
Lithupa tsa graphite tse hlahisoang ke Hexi Carbon Company li na le conductivity e ntle ea motlakase, conductivity ea mocheso, lubricity le botsitso ba lik'hemik'hale. Melamu ea graphite e bonolo ho sebetsa ebile e theko e tlaase, 'me e ka sebelisoa lits'ebetsong tse fapa-fapaneng: mechine, metallurgy, indasteri ea lik'hemik'hale, ho lahla, li-alloys tse se nang ferrous, li-ceramics, semiconductors, meriana, tšireletso ea tikoloho joalo-joalo. Boholo ba lithupa tsa graphite tse hlahisoang ke k'hamphani ea rona li sebelisoa ke bareki bakeng sa likarolo tsa ho futhumatsa motlakase ka har'a libopi tsa vacuum tse phahameng tsa mocheso. Ho hanyetsa mocheso o phahameng, mocheso o phahameng ka ho fetisisa oa ho sebetsa o ka fihla ho 3000 ℃, ho hanyetsa mocheso o babatsehang le ho hanyetsa serame, coefficient e nyenyane ea ho atolosa mocheso, coefficient e kholo ea mocheso oa mocheso le resistivity (8-13) × 10-6 Ω m.
Melamu ea graphite eo re e hlahisang e na le litšobotsi tse latelang:
1. Ho hanyetsa mocheso o phahameng: ntlha e qhibilihisang 3850 ℃ 50 ℃
2. Ho hanyetsa mocheso oa mocheso: E na le khanyetso e ntle ea mocheso oa mocheso le coefficient e nyenyane ea ho atolosa mocheso, kahoo e na le botsitso bo botle.
3. E babatsehang mocheso le motlakase conductivity. Conductivity ea eona ea mocheso e phahame ka makhetlo a 4 ho feta ea tšepe e sa hloekang, ka makhetlo a 2 ho feta ea carbon steel le makhetlo a 100 ho feta a nonmetal e tloaelehileng.
4. Lubricity: Lubricity ea graphite rod e tšoana le ea molybdenum disulfide, friction coefficient e ka tlase ho 0.1, 'me lubricity ea eona e fapana ho ea ka boholo ba sekala. Ha karo-karolelano e le kholoanyane, coefficient ea khohlano e nyane le lubricity e betere.
5. Ho tsitsa ha lik'hemik'hale: Graphite e na le botsitso bo botle ba lik'hemik'hale mochesong oa kamore 'me e hanyetsana le acid, alkali le li-solvents
Hexi carbon e na le bokhoni bo matla ba tlhahiso ea graphite rod / carbon rod. Ho latela likopo tse fapaneng tsa bareki, re fana ka boholo bo ikhethileng ba ho itšeha, bo ka etsang melamu ea graphite | lithupa tsa khabone tse fihlelang litlhoko tsa hau, tse nang le bophara bo tlohang ho 50 mm ho isa ho 1200 mm.
