ʻO ke kūlana kiʻekiʻe a me ke kūlana kiʻekiʻe Calcined Petroleum Coke Calcined Petroleum Coke
Palapala noi
1. Hiki ke hoʻohana 'ia e like me ka wahie no boilers, mahu-electricity symbiosis, sima kilns, etc.
2. Ka hana ʻana i nā electrodes anode hoʻoheheʻe alumini
3. Hoʻohana pololei ʻia ma ke ʻano he kumu kalapona no nā kinikona e like me ka phosphorus elemental, calcium carbide, a me ka carbide silika.
4. Hana ʻia i electrodes no ka hana ʻana i ka phosphorus elemental, carbon dioxide, carbonization, a me nā umu uila silika carbide.
5. Hana ʻia me ka graphite
Ma muli o kona hoʻolālā kūikawā, loaʻa i ka graphite recarburizer nā waiwai kūikawā
1) ʻAno pale wela kiʻekiʻe: ʻO ka helu heheʻe o ka graphite ʻo 3850 ± 50 ° C a ʻo ka paila he 4250 ° C.ʻOiai inā ua puhi ʻia e kahi wela wela kiʻekiʻe loa, he liʻiliʻi loa ke kaumaha o ke kaumaha, a liʻiliʻi loa hoʻi ka coefficient hoʻonui wela.Piʻi ka ikaika o ka graphite me ka piʻi ʻana o ka mahana, a ma 2000 ° C, pālua ka ikaika o ka graphite.
2) Ka uila a me ka thermal conductivity: ʻO ka conductivity uila o ka graphite he hoʻokahi haneli kiʻekiʻe ma mua o nā mineral non-metallic maʻamau.ʻOi aku ka hoʻoili wela ma mua o nā mea metala e like me ke kila, hao, a me ke kēpau.Hoʻemi ka conductivity thermal me ka piʻi ʻana o ka mahana, a ma nā wela kiʻekiʻe loa, hana ka graphite ma ke ʻano he insulator wela.Hiki i ka graphite ke hoʻokele i ka uila no ka mea, ʻo kēlā me kēia kalapona kalapona i loko o ka graphite e hoʻokumu i 3 covalent wale nō me nā kalapona kalapona ʻē aʻe, a ʻo kēlā me kēia kalapona kalapona e paʻa mau ana i 1 electron manuahi e hoʻouna i nā uku.
3) Lubricity: ʻO ka hana lubricating o ka graphite e pili ana i ka nui o nā flakes graphite.ʻO ka nui o nā flakes, ʻoi aku ka liʻiliʻi o ka friction coefficient a ʻoi aku ka maikaʻi o ka hana lubricating.
4) Paʻa kemika: He kūpaʻa kemika maikaʻi ka Graphite i ka wela o ka lumi, a kū i ka waika, alkali a me nā mea hoʻoheheʻe kūlohelohe.
5) Plasticity: He paʻakikī maikaʻi ka graphite a hiki ke ʻōwili ʻia i loko o nā ʻāpana lahilahi.
6) ʻO ke kūpaʻa haʻalulu wela: Ke hoʻohana ʻia ka graphite ma ka lumi wela, hiki iā ia ke pale i nā loli koʻikoʻi o ka mahana me ka ʻole o ka pōʻino.Ke hoʻololi koke ka mahana, hoʻololi liʻiliʻi ka leo o ka graphite, a ʻaʻole hiki mai nā māwae.
