Cov khoom ntawm graphite

Graphite thiab nws cov khoom muaj cov khoom zoo xws li cov kua qaub tiv thaiv, kev tiv thaiv corrosion, kub tsis kam ntawm 3000 degree thiab tsis kub tsis kam ntawm -204 degree, thiab tau dav siv hauv metallurgy, tshuaj lom neeg kev lag luam, petrochemical kev lag luam, siab zog physics. , aerospace, electronics, thiab lwm yam. Cov yam ntxwv tshwj xeeb ntawm graphite yog kwv yees li hauv qab no:

1. Super kub tsis kam

Lub melting point ntawm graphite yog 3850 ± 50 degree thiab lub boiling point yog 4250 degree. Txawm hais tias nws raug kub hnyiab los ntawm ultra-siab kub arc, qhov poob qis me me thiab thermal expansion coefficient kuj me me. Lub zog ntawm graphite nce nrog qhov nce ntawm qhov kub thiab txias. Thaum 2000 degree, lub zog ntawm graphite doubles.

2. Graphite khoom muaj thermal conductivity zoo thiab thermal poob siab kuj. Thaum siv nyob rau hauv chav tsev kub, graphite tuaj yeem tiv taus qhov kev hloov pauv ntawm qhov kub thiab txias yam tsis muaj kev puas tsuaj. Thaum qhov kub thiab txias hloov pauv, qhov ntim ntawm graphite tsis hloov ntau thiab tsis muaj qhov tawg yuav tshwm sim.

3. Graphite khoom muaj tshuaj stability thiab corrosion kuj. Graphite muaj tshuaj lom neeg ruaj khov nyob rau hauv chav tsev kub thiab tsis corroded los ntawm ib tug muaj zog acid, muaj zog alkali thiab organic hnyav.

4. Graphite khoom yog ib puag ncig tus phooj ywg thiab noj qab nyob zoo, tsis muaj hluav taws xob muaj kuab paug, thiab tiv taus qhov kub thiab txias. Cov pa roj carbon yuav tsum tau ua cov txheej txheem graphitization tsawg kawg yog kaum hnub thiab hmo ntuj nyob rau hauv qhov kub thiab txias ntawm 2000-3300 degrees kom dhau los ua graphite. Yog li ntawd, cov tshuaj lom thiab teeb meem nyob rau hauv cov graphite tau raug tso tawm ntev, thiab nws ruaj khov heev nyob rau hauv 2000 degrees.

5. Graphite khoom muaj adsorption zoo. Cov qauv pore ntawm cov pa roj carbon ua rau cov pa roj carbon zoo adsorption, yog li cov pa roj carbon feem ntau siv los ua cov khoom siv adsorption kom nqus dej noo, tsw, tshuaj lom, thiab lwm yam.

Xinhui Carbon tshwj xeeb hauv kev tsim thiab muag khoom ntawm graphite thiab carbon, thiab tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom hauv ntau qhov chaw.
