ʻAno hana no ka pale ʻana i ka graphite flake mai ka oxidized ʻana i ka mahana kiʻekiʻe

I mea e pale aku ai i ka pohō ʻana o ka pala i hoʻokumu ʻia e ka oxidation o ka flake graphite i ka mahana kiʻekiʻe, pono e ʻimi i kahi mea e kau ai i kahi ʻaʻahu ma luna o ka mea wela kiʻekiʻe, hiki ke pale pono i ka flake graphite mai ka oxidation i ka mahana kiʻekiʻe. No ka loaʻa ʻana o kēia ʻano ʻaʻahu anti-oxidation flake graphite, pono mua mākou e loaʻa kekahi mau ʻano e like me ke kūpaʻa wela kiʻekiʻe, ka compactness maikaʻi, ka hana anti-corrosion maikaʻi, ka hiki ke anti-oxidation ikaika a me ka paʻakikī kiʻekiʻe. Ke kaʻana like nei nā mea hoʻoponopono graphite Furuite ma lalo nei i nā ʻano hana e pale aku ai.graphite ʻāpanamai ka oxidized ʻia ma ke ana wela kiʻekiʻe:

1. E hoʻohana i nā mea me ke kaomi mahu ma lalo o 0.1333MPa (1650 ℃) a me nā waiwai piha maikaʻi.

2. E koho i ka mea aniani e hoʻokō ana i nā koi hana ma ke ʻano he mea sila ponoʻī, a e lilo ia i mea sila māwae ma ka mahana hana.

3. Wahi a ka hana o ka ikehu manuahi maʻamau o ka hopena me ka oxygen me ka mahana, ma ka mahana hana kila (1650-1750 ℃), ua koho ʻia nā mea me ka pilina kiʻekiʻe i ka oxygen ma mua o ke kalapona-oxygen e lawe mua i ka oxygen, i mea e hoʻopau ai iā lākou iho a pale i kagraphite ʻāpanaʻOi aku ka nui o ka nui o ka pae hou i hana ʻia ma hope o ka oxidation ma mua o ka pae mua, he mea kōkua ia e ālai i ke kahawai hoʻolaha o loko o ka oxygen a hana i kahi pale oxidation.

4. Ma ka mahana hana, hiki ke hoʻopili ʻia kahi nui o nā mea i hoʻokomo ʻia e like me Al2O3, SiO2 a me Fe2O3 i ke kila hoʻoheheʻe ʻia, ka mea e hana pū me lākou iho i ka sinter, i komo mālie ai nā mea like ʻole mai ke kila hoʻoheheʻe ʻia i loko o ka uhi.

Hoʻomanaʻo mai ka graphite Furuite iā mākou ʻo ka mahana oxidation o ka flake graphite ma nā wahi hana nui o Kina he 560815 ℃ ke loaʻa ka nui o ke kalapona he 88% 96% a ʻoi aku ka nui o ka ʻāpana ma mua o -400 mesh. I waena o lākou, ke loaʻa ka nui o ka ʻāpana o ka graphite he 0.0970.105mm, ʻo ka mahana oxidation o ka graphite me ka ʻoi aku o 90% o ka nui o ke kalapona he 600815 ℃ a ʻo ka graphite me ka emi ma mua o 90% o ka nui o ke kalapona he 62075 ℃. ʻOi aku ka crystallinegraphite ʻāpanaʻo ia hoʻi, ʻoi aku ke kiʻekiʻe o ka mahana kiʻekiʻe o ka oxidation, a ʻoi aku ka liʻiliʻi o ka pohō kaumaha oxidation ma ka mahana kiʻekiʻe.
