ʻO ke koʻokoʻo graphite Pākē
ʻO nā koʻokoʻo graphite i hana ʻia e Hexi Carbon Company he mau uila maikaʻi, conductivity thermal, lubricity a me ke kūpaʻa kemika. He mea maʻalahi ka hana a me ka maʻalahi nā koʻokoʻo graphite, a hiki ke hoʻohana ʻia i nā noi like ʻole: mīkini, metallurgy, ʻoihana kemika, hoʻolei, nonferrous alloys, ceramics, semiconductor, lāʻau lapaʻau, palekana kaiapuni a pēlā aku. ʻO ka hapa nui o nā koʻokoʻo graphite i hana ʻia e kā mākou hui e hoʻohana ʻia e nā mea kūʻai aku no nā mea hoʻomehana uila i nā umu wela wela. ʻO ke kūpaʻa wela kiʻekiʻe, hiki ke piʻi ka mahana hana kiʻekiʻe loa i 3000 ℃, ke kūpaʻa wela maikaʻi a me ke kūpaʻa anu, ka liʻiliʻi hoʻonui hoʻonui wela, ka nui o ka conductivity thermal a me ka resistivity (8-13) × 10-6 Ω m.
ʻO nā koʻokoʻo graphite a mākou e hana ai i kēia mau hiʻohiʻona:
1. Palena wela kiʻekiʻe: helu heheʻe 3850 ℃ 50 ℃
2. Thermal ha'alulu kū'ē: He maikaʻi ka wela haʻalulu kū'ē a me ka liʻiliʻi thermal hoʻonui coefficient, no laila, he maikai paʻa.
3. ʻOi aku ka maikaʻi o ka wela a me ka uila. He 4 mau manawa kiʻekiʻe ma mua o ke kila kila, 2 mau manawa kiʻekiʻe ma mua o ke kila kalapona a me 100 mau manawa kiʻekiʻe ma mua o ka mea hao ʻole.
4. Lubricity: ʻO ka lubricity o ke koʻokoʻo graphite e like me ka molybdenum disulfide, ʻoi aku ka liʻiliʻi o ka friction ma mua o 0.1, a ʻokoʻa kona lubricity me ka nui o ka unahi. ʻOi aku ka nui o ka ratio, ʻoi aku ka liʻiliʻi o ka friction coefficient a ʻoi aku ka maikaʻi o ka lubricity.
5. Paʻa kemika: He kūpaʻa kemika maikaʻi ka Graphite i ka mahana o ka lumi a kū i ka waika, alkali a me nā mea hoʻoheheʻe organik.
Loaʻa i ka Hexi carbon ka mana hana ikaika o ka graphite rod/carbon rod. Wahi a nā noi a nā mea kūʻai aku, hāʻawi mākou i nā ʻokiʻoki maʻamau, hiki ke hana i nā koʻokoʻo graphite | nā koʻokoʻo kalapona i kūpono i kāu mau koi, me nā anawaena mai 50 mm a 1200 mm.
