Graphite jẹ allotrope ti erogba, kirisita iyipada laarin awọn kirisita atomiki, awọn kirisita irin ati awọn kirisita molikula.Gbogbogbo grẹy dudu, asọ asọ, rilara ọra. Imudara ooru ni afẹfẹ tabi atẹgun ti o jo ati gbejade oloro oloro. Organic acids.Ti a lo bi aṣoju antiwear ati ohun elo lubricating, ṣiṣe ikoko, elekiturodu, batiri gbigbẹ, aṣiwaju ikọwe.Iwọn ti erin lẹẹdi: lẹẹdi ti ara, lẹẹdi kirisita ti o nipọn, lẹẹdi flake, lẹẹdi cryptocrystalline, lulú lẹẹdi, iwe lẹẹdi, lẹẹdi ti o gbooro sii, emulsion lẹẹdi, lẹẹdi ti o gbooro sii, lẹẹdi amọ ati lulú lẹẹdi adaṣe, abbl.
1. resistance iwọn otutu giga: aaye fifa ti lẹẹdi jẹ 3850 ± 50 ℃, paapaa lẹhin sisun apọju iwọn otutu ti o ga, pipadanu iwuwo kere pupọ, isodipupo imugboroosi jẹ kekere pupọ. . Ni 2000 ℃, agbara ti lẹẹdi jẹ ilọpo meji.
2. conductive, thermal conductivity: conductivity of graphite is one hundred times higher than the general non-metallic ore.The thermal conductivity of steel, iron, lead and other metal materials. iwọn otutu ti o ga, lẹẹdi sinu idabobo;
3. lubricity: iṣẹ ṣiṣe lubrication ti lẹẹdi da lori iwọn ti flake graphite, flake, isodipupo ikọlu jẹ kere, iṣẹ lubrication dara julọ;
4. iduroṣinṣin kemikali: lẹẹdi ni iwọn otutu yara ni iduroṣinṣin kemikali to dara, resistance acid, resistance alkali ati resistance ipata epo;
5. ṣiṣu: lile graphite jẹ dara, o le fọ sinu iwe tinrin pupọ;
6. Idaabobo mọnamọna igbona: lẹẹdi ni iwọn otutu yara nigba lilo le koju awọn iyipada to lagbara ni iwọn otutu laisi ibajẹ, iyipada iwọn otutu, iwọn didun ti iyipada lẹẹdi diẹ, kii yoo fọ.
1. Onínọmbà tiwqn: erogba ti o wa titi, ọrinrin, awọn idoti, ati bẹbẹ lọ;
2. Idanwo iṣẹ ṣiṣe ti ara: lile, eeru, iki, fineness, iwọn patiku, yiyipo, walẹ kan pato, agbegbe dada kan pato, aaye yo, ati bẹbẹ lọ.
3. Idanwo awọn ohun -ini ẹrọ: agbara fifẹ, brittleness, idanwo atunse, idanwo fifẹ;
4. Igbeyewo iṣẹ ṣiṣe kemikali: resistance omi, agbara, acid ati resistance alkali, resistance ipata, resistance oju ojo, resistance ooru, abbl.
5. Awọn ohun elo idanwo miiran: elekitiriki itanna, ibaramu igbona, lubrication, iduroṣinṣin kemikali, idaamu mọnamọna gbona
