Ke ʻano no ka pale ʻana i ka flake graphite mai ka hoʻokahe ʻia ʻana i ka wela kiʻekiʻe

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 flake graphite anti-oxidation coat, pono mākou e loaʻa i kekahi mau hiʻohiʻona e like me ke kūpaʻa wela kiʻekiʻe, ka compactness maikaʻi, ka hana anti-corrosion maikaʻi, ka ikaika anti-oxidation ikaika a me ka paʻakikī kiʻekiʻe. Kaʻana like nā mea hoʻoponopono graphite Furuite i nā ala e pale aigraphite liʻiliʻimai ka oxidized ma ke kiʻekiʻe wela:

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 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, ma ka mahana hana kila (1650-1750 ℃), ua koho ʻia nā mea me ka pili kiʻekiʻe i ka oxygen ma mua o carbon-oxygen e lawe mua i ka oxygen, no laila e oxidize iā lākou iho a pale i kagraphite liʻiliʻi. ʻOi aku ka nui o ka puʻupuʻu hou i hana ʻia ma hope o ka hoʻoheheʻe ʻana ma mua o ka pae kumu, he mea kōkua ia e ālai i ke kahawai hoʻoheheʻe 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.

Hoʻomanaʻo mai ʻo Furuite graphite iā mākou ʻo ka mahana o ka oxidation o ka flake graphite ma nā wahi hana nui o Kina ʻo 560815 ℃ ke 88%96% ka nui o ke kalapona a ʻoi aku ka nui o ka nui ma luna o -400 mesh. Ma waena o lākou, inā ʻo 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 ℃ a ʻo ka graphite me ka liʻiliʻi o 90% carbon content he 62075 ℃. ʻOi aku ka crystallinegraphite liʻiliʻiʻo ia, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka wela o ka oxidation, a ʻoi aku ka liʻiliʻi o ke kaumaha o ka oxidation i ka wela kiʻekiʻe.
