Hana ʻia ka pepa graphite me ka graphite flake kalapona kiʻekiʻe ma o ka mālama kemika a me ka hoʻonui ʻana i ka wela kiʻekiʻe. He laumania kona helehelena, ʻaʻole ʻike ʻia nā ʻōhū, nā māwae, nā wrinkles, nā ʻōpala, nā haumia a me nā hemahema ʻē aʻe. ʻO ia ke kumu kumu no ka hana ʻana i nā sila graphite like ʻole. Hoʻohana nui ʻia ia i ka hoʻopaʻa ʻana a me ka hoʻopaʻa paʻa ʻana o nā mīkini, nā paipu, nā ʻōpala a me nā valves i ka mana uila, petroleum, kemika, instrumentation, machinery, daimana a me nā ʻoihana ʻē aʻe. He mea hoʻopaʻa hoʻopaʻa hou kūpono ia e pani ai i nā sila maʻamau e like me ka rubber, fluoroplastics a me asbestos. .
ʻO nā kikoʻī o ka pepa graphite ma muli o kona mānoanoa. He ʻokoʻa ka hoʻohana ʻana o ka pepa graphite me nā kikoʻī like ʻole a me ka mānoanoa. Hoʻokaʻawale ʻia ka pepa graphite i ka pepa graphite maʻalahi, ka pepa graphite ultra-thin, ka pepa graphite i hoʻopaʻa ʻia, ka pepa graphite thermally conductive, ka pepa graphite conductive, a me nā mea ʻē aʻe.
6 mau hiʻohiʻona o ka pepa graphite:
1. Maʻalahi o ka hana ʻana: Hiki ke ʻoki ʻia ka pepa graphite i nā ʻāpana like ʻole, nā ʻano a me nā mānoanoa, a hiki ke hāʻawi ʻia i nā papa pālahalaha, a hiki ke ʻoki ʻia ka mānoanoa mai 0.05 a 1.5m.
2. ʻO ke kūpaʻa wela kiʻekiʻe: hiki i ka wela kiʻekiʻe o ka pepa graphite ke piʻi i 400 ℃, a hiki ke emi ka liʻiliʻi ma lalo o -40 ℃.
3. ʻO ka nui o ka thermal conductivity i loko o ka mokulele o ka pepa graphite hiki ke piʻi i 1500W / mK, a ʻo ke kūpaʻa wela he 40% haʻahaʻa ma mua o ka alumini a me 20% haʻahaʻa ma mua o ke keleawe.
4. Hoʻololi: Hiki ke hana maʻalahi i ka pepa graphite i nā laminates me ka metala, ka papa insulating a i ʻole ka lipine ʻaoʻao ʻelua, kahi e hoʻonui ai i ka hoʻolālā hoʻolālā a hiki ke loaʻa i ka pipili ma ke kua.
5. Māmā a lahilahi: ʻO ka pepa graphite he 30% ka māmā ma mua o ka alumini o ka nui like a me ka 80% māmā ma mua o ke keleawe.
6. Maʻalahi o ka hoʻohana ʻana: Hiki ke hoʻopili maikaʻi ʻia ka graphite heat sink i kekahi ʻaoʻao pālahalaha a me ka curved.
I ka mālama ʻana i ka pepa graphite, e noʻonoʻo i kēia mau mea ʻelua:
1. ʻO kahi mālama mālama: ʻOi aku ka maikaʻi o ka pepa graphite e waiho ʻia ma kahi maloʻo a palahalaha, ʻaʻole i ʻike ʻia i ka lā e pale ai i ka ʻomi ʻana. I ka wā o ke kaʻina hana, hiki iā ia ke hōʻemi i nā collisions; loaʻa iā ia kekahi degere o ka conductivity, no laila, i ka wā e pono ai ke mālama ʻia, pono e mālama ʻia mai ke kumu mana. uwea uila.
2. Kāohi i ka haʻihaʻi: He palupalu loa ka pepa graphite i ke ʻano, hiki iā mākou ke ʻoki iā ia e like me nā koi, i mea e pale ai iā lākou mai ka haki ʻana i ka wā o ka waiho ʻana, ʻaʻole kūpono ia no ka hoʻopili ʻana a i ʻole ke kuʻi ʻana a me ka ʻoki ʻana i kahi kihi liʻiliʻi. Ua kūpono nā huahana pepa graphite maʻamau no ka ʻoki ʻana i nā ʻāpana.
