ʻElima mau hiʻohiʻona o ka fiber aramid
Ka lole Aramid,ʻo ia hoʻi ka lole Kevlar, ka lole fiber aramid, ka lole aramid, heʻano lole me ka pale a me ka mālamaʻana i ka wela.Loaʻa iā ia ka nui o nā noi i ka ʻoihana a me ka pale kaua.Loaʻa iā ia nā hiʻohiʻona nui:
1. ʻO nā waiwai mechanical maikaʻi ʻo Aramid he polymer maʻalahi me ka ikaika haʻihaʻi kiʻekiʻe ma mua o ka polyester maʻamau, pulupulu, nylon, a me nā mea ʻē aʻe, me ka elongation ʻoi aku ka maikaʻi, ka manaʻo palupalu a me ka spinnability maikaʻi, a hiki ke hana i nā fibers staple o nā ʻano denier a me ka lōʻihi.I loko o nā mīkini lole lole maʻamau, hana ʻia nā fibers a me nā filament i nā wili like ʻole a i ulana ʻia i nā lole a me nā lole i ulana ʻole ʻia.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.Loaʻa i nā meta-aramids ka palena o ka oxygen index (LOI) i ʻoi aku ma mua o 28 a no laila ʻaʻole e hoʻomau i ke ahi ke haʻalele i ka lapalapa.ʻO ka hana hoʻopaʻa ahi o Newstar® meta-aramid e hilinaʻi ʻia i kona ʻano kemika ponoʻī, no laila he fiber pale ahi mau ʻaʻole e hōʻemi a nalowale paha kona mau waiwai pale ahi ma muli o ka hoʻohana ʻana i ka manawa a me ka manawa holoi.Loaʻa i ka Newstar® meta-aramid ke kūpaʻa wela maikaʻi, hiki ke hoʻohana mau ʻia ma 205°C, a hiki ke mālama i ka ikaika kiʻekiʻe ma nā wela kiʻekiʻe ma luna o 205°C.Loaʻa i ka Newstar® meta-aramid ka wela hoʻoheheʻe kiʻekiʻe a ʻaʻole e hoʻoheheʻe a hoʻoheheʻe ʻia.Heheʻe ma lalo o nā kūlana wela kiʻekiʻe.Hoʻomaka wale ka carbonization ma nā mahana ma luna o 370°C.
3.He kū'ē maikaʻi loa ka meta-aramid paʻa i ka hapa nui o nā kemika, hiki ke kūʻē i ka nui o nā waikawa inorganic kiʻekiʻe, a he kūpaʻa alkali maikaʻi i ka lumi wela.
4. Loaʻa ka pale ʻana i ka radiation me ka meta-aramid maikaʻi loa.No ka laʻana, ma lalo o ka hoʻolaha lōʻihi i ka 1.2 × 10-2 w / in2 ultraviolet rays a me 1.72 × 108rads gamma rays, ʻaʻole i loli ko lākou ikaika.
5. Hāʻawi ka meta-aramid paʻa i ka friction maikaʻi loa a me ke kūpaʻa kemika.Ma hope o 100 holoi ʻana, hiki ke piʻi aku ka ikaika o ka waimaka o nā lole i mālama ʻia me Newstar® meta-aramid ma mua o 85% o ka ikaika kumu.
