ʻO nā hiʻohiʻona o ka fiber aramid

1, maikaʻi mechanical waiwai

ʻO ka fiber Aramid kahi ʻano polymer maʻalahi, ʻoi aku ka ikaika o ka haki ʻana ma mua o ka polyester maʻamau, ka pulupulu, nylon, etc.Hiki ke hana ʻia i loko o nā pulupulu pōkole a me nā filament me nā mea hōʻole a me nā lōʻihi like ʻole, hiki ke hana ʻia i nā lole a me nā lole i ulana ʻole ʻia me nā helu ʻokoʻa i loko o ka mīkini textile maʻamau.Ma hope o ka pauʻana, hiki iā ia ke hoʻokō i nā koi o nā lole pale ma nāʻano likeʻole.

2. ʻOi aku ka maikaʻi o ka pale ʻana i ka lapalapa ahi a me ka pale wela.

ʻOi aku ka nui o ka index oxygen index (LOI) o ka fiber aramid ma mua o 28, no laila ʻaʻole ia e hoʻomau i ke ahi ke haʻalele ʻo ia i ka lapalapa.Hoʻoholo ʻia ka waiwai o ka flame retardant o ka aramid fiber e kona ʻano kemika ponoʻī, no laila he fiber retardant mau loa ia, a ʻaʻole e hōʻemi ʻia a nalowale paha kāna mau waiwai ahi ma muli o ka manawa hoʻohana a me nā manawa holoi.ʻO ka fiber Aramid ka paʻa wela maikaʻi, hiki ke hoʻohana mau ʻia ma 300 ℃, a hiki ke mālama i ka ikaika kiʻekiʻe ma ke kiʻekiʻe o ka mahana ma mua o 380 ℃.He kiʻekiʻe ka mahana decomposition o ka fiber Aramid, a ʻaʻole ia e hoʻoheheʻe a kulu paha i ka wela kiʻekiʻe, a e lohi ia i ka carbonize ke kiʻekiʻe ka mahana ma mua o 427 ℃.

3. Nā waiwai kemika paʻa

He kūʻē maikaʻi loa ka fiber Aramid i ka hapa nui o nā kemika, ka nui o nā waikawa inorganic kiʻekiʻe a me ke kūpaʻa alkali maikaʻi i ka lumi wela.

4. Ke pale ʻana i ka radiation

ʻO ka fiber Aramid ka maikaʻi o ka pale radiation.No ka laʻana, ma lalo o ka irradiation lōʻihi o 1.2 × 10-2 w / in2 ultraviolet rays a me 1.72 × 108rads gamma rays, ʻaʻole i loli kona ikaika.

5. Ka lōʻihi

ʻO ka fiber Aramid ka maikaʻi o ka friction a me ka pale kemika.Ma hope o 100 mau manawa o ka holoi ʻana, hiki i ka haki ʻana o ke kaula, lipine a i ʻole ka lole i hana ʻia e ka aramid fiber hiki ke hiki i 85% o ka ikaika kumu.
