He aha nā noi a me nā hiʻohiʻona o ka Aramid Fiber?

ʻO ka Aramid ka pale ahi maolilole lole.No kona mau waiwai kino a me kemika, loaʻa iā ia ka manaʻolana hoʻohana ākea ma nā kahua he nui. He ʻano ia o ka fiber synthetic kiʻekiʻe i hana ʻia e ka wili ʻana i ka resin kūikawā. Loaʻa iā ia kahi ʻano molekala kūʻokoʻa, kahi i hoʻokumu ʻia e kahi kaulahao lōʻihi o ka pilina pili ʻana o nā paʻa amide a me nā apo ʻala. E like me ka ʻokoʻa o ka molecular structure, ua māhele ʻia ka aramid i meso-aramid (Aramid I, 1313), para-aramid (Aramid II, 1414) a me heterocyclic aramid (Aramid III). A he aha nā noi a me nā hiʻohiʻona o ka fiber aramid?

Pono o Aramid

Loaʻa iā ia ka hana maikaʻi loa, e like me ka ikaika kiʻekiʻe, ka modulus kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka waikawa, ke kūpaʻa alkali, ke kaumaha māmā, ka insulation, ka pale ʻana i ka wā kahiko, kūpaʻa.kemikahale, palekana puhi a me ke ola lōʻihi.

Nā pōʻino o Aramid

Loaʻa iā ia ka pale māmā maikaʻi ʻole a me ka pale UV. ʻAʻole kūʻē ia i ka waikawa ikaika a i ʻole ka alkali ikaika. He haʻahaʻa kona ikaika hoʻoemi a me ka modulus kaomi. ʻO ka ikaika paʻa o ka aramidpulupulua he haʻahaʻa ka pilina resin. Loaʻa ʻole ia i ka hoʻomaʻamaʻa ʻana. A e maʻalahi ka hydrolyzed.
