Inoa Mea: Aramid Fiber
Kahua noi
ʻO Aramid fiber kahi ʻano hou o ka fiber synthetic kiʻekiʻe, ka ikaika ultra-kiʻekiʻe, ka modulus kiʻekiʻe a me ke kūpaʻa kiʻekiʻe o ka mahana, ka waikawa a me ke kūpaʻa alkali, ke kaumaha māmā, nā waiwai maikaʻi loa, e like me 5 ~ 6 mau manawa o ke kaula kila ma kona ikaika, modulus o ke kila uea a puluniu aniani paha 2 ~ 3 manawa, toughness mea 2 manawa o ka uea, a me ke kaumaha mea wale ma kahi o 1/5 o ke kila uea, ka mahana o 560 degere, mai wawahi, aole hehee.
Loaʻa iā ia ka insulation maikaʻi a me nā waiwai anti-kahiko, a he lōʻihi ke ola.ʻO ka loaʻa ʻana o ka aramid fiber i manaʻo ʻia he hana koʻikoʻi koʻikoʻi i ka honua honua.
ʻO ka fiber Aramid kahi mea kaua koʻikoʻi no ka pale aupuni.I mea e hoʻokō ai i nā pono o ke kaua hou, i kēia manawa, ua hana ʻia nā pālule pōkā o nā ʻāina i kūkulu ʻia e like me ʻAmelika Hui Pū ʻIa a me United Kingdom i ka fiber aramid.ʻO ka māmā o nā kāleʻa pōkā a me nā mahiole aramid fiber e hoʻomaikaʻi maikaʻi i ka wikiwiki wikiwiki a me ka lethality o nā pūʻali koa.I ke Kaua Kaiwa, ua hoʻohana nā mokulele ʻAmelika a me Palani i ka nui o nā mea hana aramid composite.Ma waho aʻe o nā noi pūʻali koa, ʻoiai ua hoʻohana nui ʻia kahi mea fiber kiʻekiʻe i ka aerospace, mechanical and electrical, construction, automotive, haʻuki waiwai a me nā mea ʻē aʻe o ka hoʻokele waiwai aupuni.Ma ke ʻano o ka mokulele a me ka aerospace, mālama ʻo aramid fiber i ka nui o ka wahie mana ma muli o kona kaumaha māmā a me ka ikaika kiʻekiʻe.Wahi a ka ʻikepili honua, i ka wā o ka hoʻomaka ʻana o ka mokulele, ʻo kēlā me kēia hoʻemi kaumaha o 1 kg ʻo ia ka hoʻemi ʻana o 1 miliona mau kālā US.Eia kekahi, ʻo ka hoʻomohala wikiwiki ʻana o ka ʻepekema a me ka ʻenehana e wehe ana i nā wahi kīwila hou no Aramid.Ua hōʻike ʻia i kēia manawa, ma kahi o 7 ~ 8% o nā huahana aramid e hoʻohana ʻia no nā lole flak, nā mahiole, a me nā mea ʻē aʻe, a ma kahi o 40% e hoʻohana ʻia no nā mea aerospace a me nā mea haʻuki.ʻO nā mea iwi iwi, nā mea kāʻei conveyor a me nā mea ʻē aʻe e pili ana i ka 20%, a me ke kaula ikaika kiʻekiʻe a me nā mea ʻē aʻe o kahi 13%.
Nā ʻano a me nā hana o ka fiber Aramid: Para-Aramid fiber (PPTA) a me interaromatic amide fiber (PMIA)
Ma hope o ka holomua o ka hoʻomohala ʻana a me ka hoʻomohala ʻana o ka fiber aramid e DuPont i nā makahiki 1960, ma mua o 30 mau makahiki, ua hele ka aramid fiber i ke kaʻina o ka hoʻololi ʻana mai nā mea hoʻolālā kaua i nā mea kīwila, a ua hoʻemi ʻia kona kumukūʻai e ka hapalua.I kēia manawa, ke oʻo nei nā hua aramid haole i ka pae noiʻi a me ka hoʻomohala ʻana a me ka hana ʻana.Ma ke kahua o ka hana ʻana o ka aramid fiber, ʻo ka para aramide fiber ka wikiwiki o ka ulu ʻana, me ka nui o kāna hana hana ma Iapana, ʻAmelika a me ʻEulopa.No ka laʻana, Kevlar mai dupont, Twaron fiber mai Akzo Nobel (hui pū me Teren), Technora fiber mai TeREN o Iapana, Terlon fiber mai Rusia, etc.
Aia nā Nomex, Conex, Fenelon fiber a pēlā aku.He paionia ʻo Dupont o ʻAmelika i ka hoʻomohala ʻana i ka aramid.He kūlana mua ia ma ka honua no ka noiʻi a me ka hoʻomohala ʻana i nā huahana hou, nā lula hana a me ka māhele mākeke.I kēia manawa, ʻoi aku ka nui o kāna mau ʻāpana Kevlar ma mua o 10, e like me Kevlar 1 49 a me Kevlar 29, a ʻo kēlā me kēia hōʻailona he mau kaukani mau kikoʻī.Ua hoʻolaha ʻo Dupont i ka makahiki i hala e hoʻonui ʻo ia i kāna hana hana Kevlar, a ua manaʻo ʻia e hoʻopau ʻia ka papahana hoʻonui i ka hopena o kēia makahiki.ʻAʻole e hoʻopau ʻia, ua hoʻonui ʻia nā ʻoihana hana aramid kaulana e like me Di Ren a me Hearst i ka hana ʻana a i hui pū ʻia paha, a ʻimi ikaika i ka mākeke, me ka manaʻo e lilo i ikaika hou i kēia ʻoihana sunrise.
ʻO ka hui German Acordis i hoʻomohala hou nei i nā huahana ultrafine contrapuntal aron (Twaron) kiʻekiʻe, ʻaʻole i wela a hoʻoheheʻe ʻia, a he ikaika kiʻekiʻe a me ke kūpaʻa ʻoki nui, hoʻohana nui ʻia i ka hana ʻana i nā lole i uhi ʻia a ʻaʻole i uhi ʻia, nā huahana i ulana ʻia a me nā mea kiʻekiʻe. - ka wela a me ka ʻoki ʻana i ke kūʻē ʻana o nā ʻano lole lole a me nā lako lole.ʻO ka maikaʻi o Twaron super thin silk he 60% wale nō o ka arylon counterpoint i hoʻohana mau ʻia i nā lole palekana hana, a hiki ke hoʻohana ʻia e hana i nā mīkina lima.· Hiki ke hoʻomaikaʻi ʻia kona hiki anti-cutting e 10%.Hiki ke hoʻohana ʻia e hana i nā lole i ulana ʻia a me nā huahana i ulana ʻia, me ka lima palupalu a me ka ʻoluʻolu o ka hoʻohana.Hoʻohana nui ʻia nā mīkina lima anti-cutting Twaron i ka ʻoihana hana kaʻa, ʻoihana aniani a me nā mea hana metala.Hiki iā lākou ke hoʻohana ʻia i loko o ka ʻoihana ulu lāʻau e hana i nā huahana pale wāwae a hāʻawi i nā lako anti-pōʻino no ka ʻoihana kaʻa lehulehu.
Hiki ke ho'ohana 'ia ka waiwai o Twaron no ka ho'olako 'ana i ke ahi me nā lole pale a me nā pale pale, a me nā ke'ena hana wela ki'eki'e e like me ka ho'olei 'ana, ka umu ahi, ka hale aniani, etc.Hiki ke hoʻohana ʻia kēia fiber hana kiʻekiʻe no ka hana ʻana i nā kaʻa kaʻa, nā hoses hoʻoluʻu, V-belt a me nā mīkini ʻē aʻe, nā kaula fiber optical a me nā lole pale pale a me nā mea pale ʻē aʻe, akā hiki ke hoʻololi i ka asbestos e like me nā mea friction a me nā mea hoʻopaʻa.
Koi Makeke
E like me ka 'ikepili, ka honua holoʻokoʻa koi o aramid puluniu mea 360,000 tons / makahiki ma 2001, a hiki i 500,000 tons / makahiki ma 2005. Ke global koi no ka aramid puluniu ke piʻi mau, a me ka aramid puluniu, e like me ka hou kiʻekiʻe-hana fiber. , ua komo i kahi wā o ka ulu wikiwiki.
