E kamaʻilio e pili ana i ke kaʻina hana o ka lole carbon fiber ma Shenzhen

Kāpena kalaponaua puhi ʻia i ka wela kiʻekiʻe ma ke ʻano he mea i hoʻoikaika ʻia i ka makahiki 1950 a hoʻohana ʻia e hana i nā mea missile.Hana ʻia nā fiber mua ma ka hoʻomehana ʻana a hiki i ka hana ʻana i ka rayon.ʻAʻole maikaʻi ke kaʻina hana, a ʻo ka hopena i loaʻa ke kalapona me ka 20 pakeneka haʻahaʻa haʻahaʻa a me nā waiwai ʻoʻoleʻa.I ka hoʻomaka ʻana o nā makahiki 1960, ʻo ka hoʻomohala ʻana a me ka hoʻohana ʻana i ka polyacrylonitrile e like me ka mea maka i hana ʻia i ka carbon fiber he 55% carbon a ʻoi aku ka maikaʻi o ka hana.ʻO ke ʻano kumu no ka hoʻololi ʻana o ka polyacrylonitrile i lilo koke i kumu kumu no ka hana mua ʻana o ka fiber carbon.

I ka makahiki 1970, ua hoʻāʻo kekahi poʻe i ka hoʻomaʻemaʻe ʻana a me ka hana ʻana i ke kalapona kalapona mai ka ʻaila.Loaʻa i kēia mau fiber ma kahi o 85% carbon a loaʻa ka ikaika flexural maikaʻi loa.ʻO ka mea pōʻino, ua kaupalena lākou i ka ikaika compressive a ʻaʻole ʻae ʻia.

He ʻāpana koʻikoʻi ka fiber carbon i nā huahana he nui, a ke ulu wikiwiki nei ka hoʻohana ʻana o ka fiber carbon i kēlā me kēia makahiki.

ʻO ka graphite fiber e pili ana i kahi ʻano fiber modulus ultra-high i hana ʻia me ka petroleum pitch ma ke ʻano he mea maka.Loaʻa i kēia mau fiber nā hiʻohiʻona o kahi hoʻonohonoho aniani ʻekolu-dimensional o ka hale i loko a he ʻano kalapona maʻemaʻe i kapa ʻia he graphite.

mea maka

ʻO ka mea maka i hoʻohana ʻia e hanakalapona kalaponaUa kapa ʻia ʻo precursor, a ma kahi o 90% o ka carbon fiber production maka mea he polyacrylonitrile.ʻO ke koena 10% i hana ʻia me ka rayon a me ka pitch petroleum.

ʻO kēia mau mea a pau he polymers organik, ʻike ʻia e nā molekala i hoʻopaʻa ʻia e nā kaula lōʻihi o nā ʻātoma kalapona.

I ke kaʻina hana, hoʻohana ʻia nā kinoea like ʻole a me nā wai, ua hoʻolālā ʻia kekahi o kēia mau mea e hoʻopili me nā fibers e hoʻokō i nā hopena kikoʻī, ua hoʻolālā ʻia nā mea ʻē aʻe, a i ʻole e pane ʻole e pale i kekahi mau hopena me nā fibers.ʻO ke ʻano kikoʻī o nā mea he nui i kēia mau kaʻina hana i manaʻo ʻia he mea huna kālepa.

hana hana

Ma ka ʻāpana kemika a me ka mīkini o kakalapona kalaponake kaʻina hana, huki ʻia nā kaula mua a i ʻole nā ​​kaula i loko o ka umu ahi a laila wela i kahi wela kiʻekiʻe loa me ka loaʻa ʻole o ka oxygen.Me ka ʻole o ka oxygen, ʻaʻole hiki ke ʻā nā fiber.Akā, ʻo ka wela kiʻekiʻe ke kumu e haʻalulu ikaika ai nā ʻātoma fiber a hiki i ka pau ʻana o nā ʻātoma non-carbon.ʻO kēia kaʻina hana, i kapa ʻia ka carbonization, aia nā pūʻolo loloa o nā fibers i hoʻopaʻa paʻa ʻia, a koe wale kekahi mau ʻātoma non-carbon i koe.He ʻano maʻamau kēia o nā hana no ka hana ʻana i nā fiber carbon me ka polyacrylonitrile.

1. He mea conductive ka lole fiber carbon, a pono e mālama ʻia mai nā lako uila a me nā kumu mana a pono e lawe ʻia nā hana pale pono i ka wā o ke kau ʻana a me ke kūkulu ʻana.

2. Pono e 'alo 'ia ke ku'o 'ana o ka lole kalapona i ka wā o ka mālama 'ana, ka lawe 'ana a me ke kūkulu 'ana.

3. Pono e hoʻopaʻa ʻia ka resin kākoʻo o ka lole kalapona kalapona a mālama ʻia mai nā kumu ahi, ka lā pololei a me nā wahi me nā kumu wela kiʻekiʻe.

4. ʻO kahi i hoʻomākaukau ʻia a hoʻohana ʻia ai ka resin e mālama pono ʻia.

5. Pono nā limahana e hana ana ma ke kahua e hana i nā hana palekana kūpono.
