Hana ʻia ka pepa graphite me ka graphite flake kalapona kiʻekiʻe ma o ka mālama kemika a me ka ʻōwili hoʻonui wela kiʻekiʻe. He laumania kona helehelena, me ka ʻole o nā pehu ʻike ʻia, nā māwae, nā wrinkles, nā ʻōpala, nā haumia a me nā kīnā ʻē aʻe. ʻO ia ke kumu no ka hana ʻana i nā sila graphite like ʻole. Hoʻohana nui ʻia ia i ka sila ʻana i nā mīkini, nā paipu, nā pamu a me nā valves i ka mana uila, ka petroleum, kemika, nā mea hana, nā mīkini, ka daimana a me nā ʻoihana ʻē aʻe. He mea sila hou kūpono ia e pani i nā sila kuʻuna e like me ka rubber, fluoroplastics a me ka asbestos. .
ʻO ke ʻano kikoʻī o ka pepa graphite e pili nui ana i kona mānoanoa. ʻOkoʻa nā hoʻohana o ka pepa graphite me nā kikoʻī a me nā mānoanoa like ʻole. Ua māhele ʻia ka pepa graphite i ka pepa graphite maʻalahi, ka pepa graphite lahilahi loa, ka pepa graphite i hoʻopaʻa ʻia, ka pepa graphite conductive thermally, ka pepa graphite conductive, a pēlā aku. Nā ʻano pepa graphite like ʻole Hiki iā ia ke pāʻani i kāna kuleana kūpono ma nā ʻano ʻoihana like ʻole.
6 mau ʻano o ka pepa graphite:
1. ʻO ka maʻalahi o ka hana ʻana: Hiki ke ʻoki ʻia ka pepa graphite i nā nui like ʻole, nā ʻano a me nā mānoanoa, a hiki ke hāʻawi ʻia nā papa pālahalaha ʻoki make, a hiki ke piʻi ka mānoanoa mai 0.05 a 1.5m.
2. Ke kūpaʻa wela kiʻekiʻe: hiki i ka mahana kiʻekiʻe o ka pepa graphite ke hiki i ka 400 ℃, a ʻo ka liʻiliʻi loa hiki ke haʻahaʻa ma mua o -40 ℃.
3. Ke alakaʻi wela kiʻekiʻe: ʻO ka alakaʻi wela kiʻekiʻe loa 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. Ka maʻalahi: Hiki ke hana maʻalahi ʻia ka pepa graphite i nā laminates me ka metala, ka papa insulating a i ʻole ka lipine ʻaoʻao pālua, kahi e hoʻonui ai i ka maʻalahi o ka hoʻolālā a hiki ke hoʻopili ʻia ma ke kua.
5. Māmā a lahilahi: ʻOi aku ka māmā o ka pepa graphite ma mua o ka alumini o ka nui like a me 80% māmā ma mua o ke keleawe.
6. Maʻalahi o ka hoʻohana: Hiki ke hoʻopili maʻalahi ʻia ka poho wela graphite i kekahi ʻili pālahalaha a piʻo.
I ka mālama ʻana i ka pepa graphite, e hoʻolohe i nā mea ʻelua aʻe:
1. Kahua mālama: ʻOi aku ka maikaʻi o ka waiho ʻana i ka pepa graphite ma kahi maloʻo a pālahalaha, a ʻaʻole hoʻi e hōʻike ʻia i ka lā e pale ai i ka ʻomi ʻia. I ka wā o ke kaʻina hana, hiki iā ia ke hōʻemi i nā collisions; loaʻa iā ia kekahi kekelē o ka conductivity, no laila ke pono e mālama ʻia, pono e mālama ʻia mai ke kumu mana. uea uila.
2. Kāohi i ka haki ʻana: He palupalu loa ke ʻano o ka pepa graphite, hiki iā mākou ke ʻoki e like me nā koi, i mea e pale ai iā lākou mai ka haki ʻana i ka wā e mālama ai, ʻaʻole kūpono ia no ka pelu ʻana a i ʻole ke kūlou ʻana a me ka pelu ʻana i kahi kihi liʻiliʻi. He kūpono nā huahana pepa graphite maʻamau no ka ʻoki ʻana i nā pepa.
