Graphite jẹ ẹya allotrope ti erogba, a iyipada gara laarin atomiki kirisita, irin kirisita ati ki o molikula kirisita.Generally grẹy dudu, asọ sojurigindin, greasy feeling.Enhanced ooru ni air tabi atẹgun ti o Burns ati ki o gbe carbon dioxide.Strong oxidizing òjíṣẹ yoo oxidize o sinu Organic acids.Used bi antiwear oluranlowo ati ki o lubricating batiri ohun elo, electroscope gbigbẹ ohun elo, electroscope. iwari lẹẹdi: lẹẹdi adayeba, lẹẹdi okuta nla, lẹẹdi flake, graphite cryptocrystalline, lulú graphite, iwe lẹẹdi, graphite ti o gbooro, emulsion graphite, graphite gbooro, graphite amọ ati lulú graphite conductive, bbl
1. giga otutu resistance: awọn yo ojuami ti graphite jẹ 3850 ± 50 ℃, paapaa lẹhin olekenka-ga otutu arc sisun, awọn àdánù làìpẹ jẹ gidigidi kekere, thermal imugboroosi olùsọdipúpọ jẹ gidigidi small.The agbara ti graphite posi pẹlu awọn ilosoke ti otutu. Ni 2000 ℃, agbara ti lẹẹdi ilọpo meji.
2. conductive, thermal conductivity: iṣiṣẹ ti graphite jẹ ọgọrun igba ti o ga ju awọn ohun elo ti kii-metallic gbogbogbo lọ.Iwọn igbona ti irin, irin, asiwaju ati awọn ohun elo irin miiran.Imudanu ti o gbona dinku pẹlu ilosoke ti iwọn otutu, paapaa ni iwọn otutu ti o ga julọ, graphite sinu idabobo;
3. lubricity: iṣẹ lubrication ti graphite da lori iwọn ti flake graphite, flake, olùsọdipúpọ edekoyede jẹ kere, iṣẹ lubrication dara julọ;
4. Iduroṣinṣin kemikali: graphite ni iwọn otutu yara ni iduroṣinṣin kemikali ti o dara, resistance acid, resistance alkali and Organic epo resistance resistance;
5. ṣiṣu: graphite toughness jẹ dara, le ti wa ni itemole sinu kan tinrin dì;
6. resistance mọnamọna gbona: graphite ni iwọn otutu yara nigba lilo le ṣe idiwọ awọn ayipada nla ni iwọn otutu laisi ibajẹ, iyipada iwọn otutu, iwọn didun graphite yipada diẹ, kii yoo kiraki.
1. igbekale tiwqn: erogba ti o wa titi, ọrinrin, awọn impurities, bbl;
2. Idanwo iṣẹ ṣiṣe ti ara: lile, eeru, viscosity, fineness, iwọn patiku, iyipada, walẹ pato, agbegbe dada kan pato, aaye yo, ati bẹbẹ lọ.
3. Idanwo awọn ohun-ini ẹrọ: agbara fifẹ, brittleness, idanwo atunse, idanwo fifẹ;
4. Idanwo iṣẹ ṣiṣe kemikali: resistance omi, agbara, acid ati resistance alkali, resistance corrosion, resistance oju ojo, resistance ooru, bbl
5. Awọn ohun elo idanwo miiran: itanna eletiriki, imudara igbona, lubrication, iduroṣinṣin kemikali, resistance mọnamọna gbona
