Nā Paipu graphite
Nā hiʻohiʻona
1. Palena wela kiʻekiʻe: ʻO ka graphite kekahi o nā mea pale wela kiʻekiʻe i ʻike ʻia. ʻO kona helu hoʻoheheʻe he 3850 ℃ ± 50 ℃, a hiki i kona helu hoʻolapalapa a hiki i 4250 ℃. Hāʻawi ʻia ia i kahi arc wela kiʻekiʻe loa ma 7000 ℃ no 10 kekona, me ka liʻiliʻi loa o ka graphite, ʻo ia ka 0.8% ma ke kaumaha. Mai kēia, hiki ke ʻike ʻia ke kūʻokoʻa o ka graphite kiʻekiʻe.
2. Ke kū'ē kū'ē wela kūikawā: Loa'a i ka Graphite ke kū'ē i ka ha'alulu wela,'o ia ho'i, ke ho'ololi koke ka mahana, he li'ili'i ke koena o ka ho'onui wela, no laila, maika'i kona kūpa'a wela a'a'ole e hana i nā māwae i ka wā e ho'ololi koke ai ka mahana.
3. Thermal conductivity a me ka conductivity: He maikaʻi ko ka graphite me ka conductivity thermal. Ke hoʻohālikelike ʻia me nā mea maʻamau, ʻoi aku ka kiʻekiʻe o kāna conductivity thermal. ʻO 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 nā mea metala maʻamau.
4. Lubricity: ʻO ka hana lubrication o ka graphite ua like ia me ka molybdenum disulfide, me ka helu friction ma lalo o 0.1. ʻOkoʻa kāna hana lubrication me ka nui o ka unahi. ʻOi aku ka nui o ka pālākiō, ʻoi aku ka liʻiliʻi o ke koena friction, a ʻoi aku ka maikaʻi o ka hana lubrication.
5. Paʻa kemika: He kūpaʻa kemika maikaʻi ka Graphite i ka wela o ka lumi, a hiki ke kū i ka ʻakika, alkali, a me nā mea hoʻoheheʻe kūlohelohe.
ʻO ke kiʻekiʻe kiʻekiʻe, ka nui o ka palaoa maikaʻi, ka maʻemaʻe kiʻekiʻe, ka ikaika kiʻekiʻe, ka lubrication maikaʻi, ka conductivity thermal maikaʻi, ke kūpaʻa haʻahaʻa haʻahaʻa, ka ikaika mechanical kiʻekiʻe, ka maʻalahi o ka hana pololei, ke kūpaʻa haʻalulu maikaʻi, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa oxidation. Loaʻa iā ia nā hōʻailona kino a me nā kemika anti-corrosion maikaʻi a kūpono i ka ʻaila-free rotary vane vacuum pumps.
ʻO ka graphite kekahi o nā mea pale wela kiʻekiʻe. ʻO 3850 ° C + 50 ° C kona helu hoʻoheheʻe ʻana, a ʻo kona wahi e hoʻolapalapa ai ʻo 4250 ° C. Hoʻohana ʻia nā ʻano like ʻole a me nā anawaena o nā paipu graphite no ka hoʻomehana ʻana i nā umu ahi a me nā māla wela.
Isostatic kaomi graphite
Loaʻa iā ia ka conductivity maikaʻi a me ka thermal conductivity, ke kūpaʻa wela kiʻekiʻe, ka liʻiliʻi liʻiliʻi o ka hoʻonui ʻana i ka wela, ka lubrication ponoʻī, ke kūpaʻa kiʻekiʻe kiʻekiʻe, ka pale ʻana i ka waikawa, ke kūpaʻa alkali, ke kūpaʻa corrosion, ke kiʻekiʻe leo nui, a me nā ʻano hana maʻalahi.
graphite i kālai ʻia
ʻO ke kiʻekiʻe kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ka ikaika mechanical kiʻekiʻe, ka hana mechanical, ke kū'ē seismic maikaʻi, a me ka pale wela kiʻekiʻe. ʻAiʻi antioxidant.
graphite haʻalulu
Hoʻonohonoho like ʻole i ka graphite koʻikoʻi. ʻO ka ikaika mechanical kiʻekiʻe a me ka hana wela maikaʻi. Nui nui keu. Hiki ke hoʻohana ʻia no ka hana ʻana i nā mea hana nui
Pehea ka lōʻihi o ka haʻi ʻana?
Hāʻawi pinepine mākou i kahi ʻōlelo i loko o 24 mau hola ma hope o ka loaʻa ʻana o ka nui a me ka nui o ka huahana. Inā he kauoha wikiwiki, hiki iā ʻoe ke kelepona pololei iā mākou.
Hāʻawi ʻia nā hōʻike hōʻike?
ʻAe, hāʻawi mākou i nā laʻana no ʻoe e nānā i kā mākou maikaʻi. ʻO ka manawa hāʻawi hāʻawi ma kahi o 3-10 mau lā. Haʻalele i nā mea e koi ana i ka hoʻopilikino.
He aha ka manawa alakaʻi no ka hana huahana?
Hoʻokumu ʻia ka pōʻai hoʻopuka ma ka nui a ma kahi o 7-12 mau lā. No nā huahana graphite, pono e hoʻohana ʻia kahi laikini mea ʻelua.
