1.Aramid fiber lako

ʻO ka inoa piha o ka fiber aramid he fiber polyamide aromatic.He polymer linear i haku ʻia me nā hui ʻala a me nā hui amide.Loaʻa iā ia nā waiwai mechanical maikaʻi loa, ka hoʻolālā kemika paʻa, nā waiwai mechanical kūpono, ka ikaika ultra-kiʻekiʻe a me ka modulus kiʻekiʻe., pale wela kiʻekiʻe, kaʻakika a me ka alkali, ke kaumaha māmā, ka pale lole a me nā mea maikaʻi'ē aʻe.Ua hoʻohana nui ʻia i nā kula e like me nā lako pale pale pale, aerospace, kūkulu a me nā lako uila.

Eia nō naʻe, ʻelua mau hemahema nui o ka aramid fiber

(1) ʻAʻole maikaʻi ka pale ʻana o ka fiber Aramid.ʻO ka hoʻoheheʻe ʻana o Ultraviolet (ka lā) ke kumu i ka hōʻino ʻana o nā fiber aramid.No laila, koi ʻia kahi ʻāpana pale, hiki ke lilo i topcoat a i ʻole kahi ʻāpana o nā mea, no ka laʻana, ua hoʻopili pinepine ʻia nā kaula aramid i kahi pale pale.

(2) He kiʻekiʻe ka hygroscopicity o ka fiber Aramid (a hiki i ka 6% o kona kaumaha), no laila pono e pale pono ʻia nā mea hoʻohuihui aramid fiber, e like me nā topcoats e hoʻemi i ka hygroscopicity.Hoʻohui ʻia, ʻo ka hoʻohana ʻana i kekahi mau ʻano aramid e hōʻemi i ka wai o ka composite i ka wā e ʻike ʻia ai i ka wai, e like me Kevlar 149 a i ʻole Armos.

2.PE fiber lako

ʻO ka PE e pili ana i ka UHMW-PE, ʻo ia ka polyethylene kaumaha nui loa.He fiber organik hana kiʻekiʻe ia i hoʻomohala ʻia i nā makahiki 1980 mua.Me ke kalapona kalapona a me ka aramid, ua ʻike ʻia ʻo ia ʻekolu mau mea ʻenehana kiʻekiʻe nui o ka honua i kēia lā.Loaʻa iā ia ka paʻa kiʻekiʻe loa a paʻakikī loa ka hoʻohaʻahaʻa ʻana, e hoʻohaumia ana i ke kaiapuni.Akā ma muli o kēia hiʻohiʻona e lilo ia i mea kūpono no ka hana ʻana i nā pale kino.Eia kekahi, kū'ē ia i ka mahana haʻahaʻa, ke kukui UV, a me ka wai.

Ma keʻano o ka paleʻana i nā pōkā haʻahaʻa haʻahaʻa,ʻo ka hana pōkā o ka fiber PE ma kahi o 30% kiʻekiʻe ma mua o ka aramid;ma keʻano o ka paleʻana i nā pōkā kiʻekiʻe,ʻo ka hana o ka fiber PE he 1.5 i ka 2 manawa o ka aramid.Hiki ke ʻōlelo ʻia ua lilo nā hemahema o ka fiber aramid i mea maikaʻi o ka fiber PE, a ua ʻoi aku ka maikaʻi o ka fiber aramid ma luna o ka fiber PE.No laila, he ʻano hiki ʻole ia no ka fiber PE e pani i ka aramid ma ke kahua o ka pale.

ʻOiaʻiʻo, he mau hemahema ka PE fiber.ʻOi aku ka haʻahaʻa haʻahaʻa o kona pae wela i ka fiber aramid.ʻO ka mahana hoʻohana o nā huahana pale fiber PE i loko o 70 ° C (hiki ke hoʻokō i nā koi o ke kino kanaka a me nā mea hana, ʻo ia hoʻi, ke koi ʻana o ka mahana o 55 ° C).Ma waho aʻe o kēia mahana, emi koke ka hana.Ke piʻi ka mahana ma mua o 150 ° C, e hoʻoheheʻe ka PE fiber, a me ka fiber aramid Hiki i ka fiber ke mālama i nā mea palekana maikaʻi ma kahi o 200 ° C, aʻaʻole e hoʻoheheʻe a hoʻoheheʻe paha ma 500 ° C;i ka wā e hālāwai ai me nā wela kiʻekiʻe ma luna o 900 ° C, e hoʻopololei pololei ʻia ia e hana i kahi papa wela wela.ʻAʻole loaʻa kēia mau mea i nā huahana pale fiber PE a ua lilo i mau pono kūʻokoʻa o nā huahana aramid.
