Nā Pono o ka Fiber Aniani i loko o nā mea hana kemika ma muli o ka Graphite

Hoʻohana nui ʻia ka Graphite i ka hana ʻana i nā mea hana kemika ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion, conductivity uila, a me ke kūpaʻa wela. Eia nō naʻe, hōʻike ka graphite i nā ʻano mīkini nāwaliwali, ʻoi aku ma lalo o ka hopena a me nā kūlana haʻalulu.puluni aniani, ma ke ʻano he mea hoʻohuihui hana kiʻekiʻe, hāʻawi i nā pōmaikaʻi koʻikoʻi ke hoʻohana ʻia i nā mea hana kemika i hoʻokumu ʻia i ka graphite ma muli o kona pale ʻana i ka wela, ka pale ʻana i ka corrosion, a me nā waiwai mechanical kiʻekiʻe. Loaʻa nā pono kikoʻī:

(1) Hoʻonui i ka hana Mechanical

Hiki i ka tensile ikaika o ke aniani aniani ke hiki i 3,450 MPa, ʻoi aku ma mua o ka graphite, ka mea maʻamau mai 10 a 20 MPa. Ma ka hoʻokomo ʻana i ka fiber aniani i loko o nā mea graphite, hiki ke hoʻomaikaʻi maikaʻi ʻia ka hana mechanical holoʻokoʻa o nā mea hana, me ka pale ʻana i ka hopena a me ka haʻalulu.

(2) Kūʻē ʻino

Hōʻike ka fiber Glass i ke kūpaʻa maikaʻi ʻana i ka hapa nui o nā waikawa, alkalis, a me nā solvents. ʻOiai ʻo ka graphite ponoʻī he kūpaʻa nui i ka corrosion,kīʻaha anianihiki ke hāʻawi i ka hana ʻoi aku ka maikaʻi ma nā kaiapuni kemika koʻikoʻi, e like me nā kūlana kiʻekiʻe a me nā kūlana kiʻekiʻe, nā ea hoʻoheheʻe ʻana, a i ʻole nā ​​kaiapuni hydrofluoric acid.

(3) Hoʻomaikaʻi ʻia nā waiwai wela

He haʻahaʻa haʻahaʻa loa ka nui o ka hoʻonui wela (CTE) ma kahi o 5.0×10−7/°C, e hōʻoiaʻiʻo ana i ka paʻa o ka dimensional ma lalo o ke kaumaha wela. Eia kekahi, ʻo kona wahi heheʻe kiʻekiʻe (1,400–1,600°C) hāʻawi i ke kūpaʻa kūwaho kiʻekiʻe. ʻO kēia mau hiʻohiʻona e hiki ai i nā mea hana graphite i hoʻoikaika ʻia i ke aniani fiber e mālama i ka kūpaʻa a me ka hana ma nā wahi wela wela me ka liʻiliʻi o ka deformation.

(4) Pono Kaumaha

Me ka mānoanoa ma kahi o 2.5 g/cm3, ʻoi aku ke kaumaha o ke aniani aniani ma mua o ka graphite (2.1–2.3g/cm3) akā ʻoi aku ka māmā ma mua o nā mea metala e like me ke kila a i ʻole aluminika. ʻO ka hoʻohui ʻana i ka fiber aniani i loko o nā mea hana graphite e hoʻonui i ka hana me ka ʻole o ka hoʻonui nui ʻana i ke kaumaha, e mālama ana i ke ʻano māmā a me ka lawe lima ʻana.

(5) Kūʻai kūpono

Hoʻohālikelike ʻia me nā mea hana kiʻekiʻe ʻē aʻe (e laʻa, carbon fiber), ʻoi aku ka maikaʻi o ke kumu kūʻai o ke aniani aniani, e lilo ia i mea maikaʻi no nā noi ʻoihana nui.

Nā Koina Mea Maka:puluni anianihoʻohana mua i ke aniani kumu kūʻai haʻahaʻa, ʻoiai ke hilinaʻi nei ka fiber carbon i ka acrylonitrile pipiʻi.

Nā kumukūʻai hana: Pono nā mea ʻelua i ka hana wela kiʻekiʻe a me ke kaomi kiʻekiʻe, akā ʻo ka hana ʻana o ka carbon fiber e pili ana i nā ʻanuʻu paʻakikī hou (e laʻa, polymerization, oxidation stabilization, carbonization), e hoʻonui i nā kumukūʻai.

Hoʻopau hou a hoʻokuʻu ʻia: He paʻakikī ke hana hou ʻana i ka fiber carbon a loaʻa i nā pilikia kaiapuni inā mālama pono ʻole ʻia, e alakaʻi ana i nā kumukūʻai kiʻekiʻe. ʻO ka fiber aniani, ʻoi aku ka maʻalahi o ka mālama ʻana a me ka ʻoluʻolu i nā hiʻohiʻona hope o ke ola.
