I mea e pale ai i ka pōʻino o ka corrosion i hana ʻia e ka oxidation o ka flake graphite i ke kiʻekiʻe wela, pono e ʻimi i kahi mea e kau ai i kahi kapa ma luna o ka mea wela kiʻekiʻe, hiki ke pale pono i ka flake graphite mai ka oxidation ma ke kiʻekiʻe wela. No ka loaʻa ʻana o kēia ʻano o ka flake graphite anti-oxidation coat, pono mākou e pale mua i ka wela kiʻekiʻe a me ka compactness.
ʻO ke kūpaʻa maikaʻi maikaʻi, ka pale ʻana i ka oxidation ikaika, ka paʻakikī kiʻekiʻe a me nā ʻano ʻē aʻe. Hōʻike ka Furuite Graphite Xiaobian i nā ʻano hana e pale ai i ka flake graphite mai ka hoʻoneʻe ʻia ʻana i ka wela kiʻekiʻe:
1. E hoʻohana i nā mea me ke kaomi mahu ma lalo o 0.1333MPa(1650*C) a me ka hana piha maikaʻi.
2. E koho i ke aniani māhele mea e hoʻokō i nā koi hana e like me ka mea hoʻopaʻa paʻa ponoʻī, a lilo ia i mea hoʻopaʻa paʻa ma ka mahana hana.
3. E like me ka hana o ka ikehu manuahi maʻamau o ka hopena me ka oxygen me ka mahana, i ka mahana hana kila (1650-1750 * C), ua koho ʻia nā mea me ka pili nui i ka oxygen ma mua o ka carbon-oxygen i koho ʻia e hopu i ka oxygen, no laila no ka hoʻoheheʻe ʻana iā lākou iho a pale i ka flake graphite. Ma hope o ka oxidation, hana ʻia kahi māhele hou me ka ratio o ka pae kumu.
Nui, he mea kōkua ia e ālai i ke kahawai diffusion i loko o ka oxygen a hana i kahi pale oxidation.
4. Ma ka mahana hana, hiki ke adsorbed ka nui o nā inclusions e like me Al2O3, SiO2 a me Fe2O3 i loko o ke kila hoʻoheheʻe ʻia, e hana pū me lākou iho i ka sinter, no laila e komo mālie nā ʻano inclusions mai ke kila hoʻoheheʻe ʻia i ka uhi.
ʻO ka mahana wela o ka flake graphite i hana ʻia ma Kina ʻo 560815 ° C ke 88%96% ka nui o ke kalapona a ʻoi aku ka nui o ka nui ma mua o 400 meshes. Ma waena o lākou, i ka wā o ka nui o ka graphite he 0.0970.105mm, ʻo ka mahana o ka oxidation o ka graphite me ka ʻoi aku o 90% carbon content he 600815 ° C a ʻo ka ʻike kalapona ma lalo o 90%.
He 620790 C ka mahana o ka inika, ʻoi aku ka maikaʻi o ka crystalline flake graphite, ʻoi aku ka kiʻekiʻe o ka wela o ka oxidation peak, a ʻoi aku ka liʻiliʻi o ke kaumaha o ke kaumaha ma ke kiʻekiʻe wela.
