Pehea e pale aku ai i ka flake graphite mai ka hoʻokahe ʻia ʻana i ka wela kiʻekiʻe

I mea e pale aku ai i ka pōʻino o ka corrosion ma muli o ka oxidation o ka flake graphite i ke kiʻekiʻe wela, 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 ma ke kiʻekiʻe wela. No ka loaʻa ʻana o kēia ʻano ʻaʻahu anti-oxidation graphite unahi, pono mākou e loaʻa i kekahi mau hiʻohiʻona e like me ke kūpaʻa kiʻekiʻe o ka wela, ka compactness maikaʻi, ka hana anti-corrosion maikaʻi, ka ikaika anti-oxidation ikaika a me ka paʻakikī kiʻekiʻe. Kaʻana like ka mea hoʻoponopono o Furuite Graphite i ke ʻano o ka pale ʻana i ka flake graphite mai ka oxidized i ka wela 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 ke aniani pae mea i kūpono i ka hana e like me ka mea hoʻopaʻa paʻa ponoʻī, a lilo ia i mea hoʻopaʻa paʻa i loko o ka mahana hana.

3. E like me ka hana hoʻololi o ka ikehu manuahi maʻamau o ka hopena me ka oxygen me ka mahana, i ka mahana hana kila (1650-1750 ℃), koho i nā mea me ka pilina kiʻekiʻe me ka oxygen ma mua o carbon-oxygen, hopu mua i ka oxygen, a oxidize iā lākou iho e pale aku. graphite liʻiliʻi. ʻOi aku ka nui o ka puʻupuʻu hou i hana ʻia ma hope o ka hoʻoheheʻe ʻia ma mua o ka pae kumu, he mea kōkua ia e ālai i ke kahawai diffusion o loko o ka oxygen a hana i ka pale oxidation.

4. Ma ka mahana hana, hiki iā ia ke komo i ka helu nui o nā inclusions e like me AL2O3, SiO2, Fe2O3 i ke kila hoʻoheheʻe ʻia, a hana pū me ia iho i ka sinter, no laila e komo mālie nā ʻokoʻa like ʻole mai ke kila hoʻoheheʻe ʻia i ka uhi.

Ke hoʻomanaʻo nei ʻo Furuite Graphite Xiaobian i ka mahana o ka oxidation o ka flake graphite ma nā wahi hana nui o Kina he 560,815 ℃ ke 88%96% ka nui o ke kalapona a ʻoi aku ka nui o ka nui ma luna o -400 mesh. I 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 600,815 ℃, a ʻo ka graphite me ka liʻiliʻi o 90% carbon content he 6200 ℃. ʻOi aku ka maikaʻi o ka graphite flake crystalline, ʻoi aku ka kiʻekiʻe o ka wela o ka oxidation peak a me ka liʻiliʻi o ka pohō kaumaha o ka oxidation ma ke kiʻekiʻe.
