Pehea e pale ai 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 uhi ai i 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 graphite unahi, 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 ka mea hoʻoponopono o Furuite Graphite i ke ʻano o ka pale ʻana i ka flake graphite mai ka oxidation i ka mahana kiʻekiʻe:

1. Hoʻohana ʻia 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 i loko o ka mahana hana.

3. Wahi a ka hana hoʻololi o ka ikehu manuahi maʻamau o ka hopena me ka oxygen me ka mahana, ma ka mahana hana kila (1650-1750 ℃), koho i nā mea me ka pilina kiʻekiʻe me ka oxygen ma mua o ke kalapona-oxygen, hopu mua i ka oxygen, a hoʻomake iā lākou iho e pale i ka graphite flake. ʻOi 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 ka pale oxidation.

4. Ma ka mahana hana, hiki iā ia ke omo i kahi nui o nā mea i hoʻokomo ʻia e like me AL2O3, SiO2, Fe2O3 i ke kila hoʻoheheʻe ʻia, a pane pū me ia iho i ka sinter, i komo mālie ai nā mea like ʻole mai ke kila hoʻoheheʻe ʻia i loko o ka uhi.

Hoʻomanaʻo ʻo Furuite Graphite Xiaobian ʻo ka mahana oxidation o ka flake graphite ma nā wahi hana nui o Kina he 560,815 ℃ 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, i ka wā he 0.0970.105mm ka nui o ka ʻāpana o ka graphite, ʻo ka mahana oxidation o ka graphite me ka ʻoi aku o 90% o ka nui o ke kalapona he 600,815 ℃, a ʻo ka graphite me ka emi iho o 90% o ka nui o ke kalapona he 6200 ℃. ʻO ka maikaʻi o ka crystalline flake graphite, ʻoi aku ka kiʻekiʻe o ka mahana kiʻekiʻe o ka oxidation a ʻoi aku ka liʻiliʻi o ka pohō kaumaha oxidation i ka mahana kiʻekiʻe.
