E pili ana iā Frankstar Kevlar (Aramid) Rope
He aramid ʻo Kevlar; he papa nā aramidkūpaʻa wela, paʻanā olonā synthetic. ʻO kēia mau ʻano o ka ikaika a me ke kūpaʻa wela e hoʻolilo ai i ke olonā Kevlar i mea kūpono loamea hana haleno kekahi mau ʻano kaula. He mau pono hana ʻoihana a me nā kalepa koʻikoʻi nā kaula a ua mau ia mai ka wā ma mua o ka moʻolelo i hoʻopaʻa ʻia.
Hoʻemi ka ʻenehana ulana kihi helix haʻahaʻa i ka hoʻolōʻihi ʻana o ke kaula Kevlar i ka haki ʻana o ka lua. ʻO ka hui pū ʻana o ka ʻenehana pre-tightening a me ka ʻenehana māka ʻelua kala e kūʻē i ka corrosion e ʻoi aku ka maʻalahi a me ka pololei o ke kau ʻana o nā mea hana lua.
ʻO ka ʻenehana ulana kūikawā a me ka hoʻoikaika ʻana o ke kaula Kevlar e mālama i ke kaula mai ka hāʻule ʻana a i ʻole ka mae ʻana, ʻoiai i nā kūlana kai ʻino.
Hiʻona
Nā ʻano māka hoʻoheheʻe wai like ʻole, nā buoys, nā cranes traction, nā kaulahao kūikawā hoʻopaʻa ikaika kiʻekiʻe, ka ikaika kiʻekiʻe loa, ka elongation haʻahaʻa, ka ʻenehana ulana ulana pālua a me ka ʻenehana hoʻopau holomua, kū i ka ʻelemakule a me ka pala o ka wai kai.
Ikaika nui, ʻili laumania, kūpaʻa i ka ʻānai ʻana, ka wela a me ke kemika.
He kiʻekiʻe loa ke kūpaʻa wela o ke kaula Kevlar. He 930 degere (F) kona wahi heheʻe a ʻaʻole ia e hoʻomaka e nalowale ka ikaika a hiki i ka 500 degere (F). He kūpaʻa loa hoʻi ke kaula Kevlar i nā waikawa, nā alkalis a me nā mea hoʻoheheʻe organik.

I hana ʻia no ke kaiapuni kai, hoʻohui ʻo Frankstar Aramid Fiber Rope i kahi ʻiwi aramid-fiber me kahi kūkulu waho polyamide-fiber. ʻO kahi ulana haʻahaʻa helix-angle a me ke kūkulu paʻa mua e hōʻemi i ka elongation haki, e hōʻoiaʻiʻo ana i ka mālama ʻana i ke kahua paʻa. ʻO ka ulana ʻili kiʻekiʻe-density e hoʻonui i ke kū'ē ʻana i ka abrasion, ʻoiai ʻo kahi ʻōnaehana ʻike kala pālua e hoʻomaʻalahi i ka hoʻokomo ʻana i lalo o ke kai. Hoʻoikaika ka hoʻoikaika multi-layer i nā hopena koʻikoʻi o ke kai, e hana ana i ke kaula kūpono no nā noi ukana kiʻekiʻe e like me ka buoy subsurface a me nā ʻōnaehana mooring-anchor.
Māmā akā ikaika loa
Hāʻawi ke ʻano hoʻolālā aramid-composite i kahi lakio ikaika-a-kaumaha kūikawā—ka nuipa liʻiliʻi, ka hiki ke lawe i ka ukana kiʻekiʻe loa.
Ke kū'ē ʻana i ka mahana kiʻekiʻe loa
Hoʻomaka ka palaho ʻana ma kahi o 500 °C, e ʻoi aku ka maikaʻi ma mua o nā olonā synthetic maʻamau.
Palekana ʻoki a me ke kuʻi kiʻekiʻe loa
Hāʻawi ke ʻano molekala paʻa e like me ke koʻokoʻo i ke kūpaʻa maikaʻi loa i ka hōʻino ʻoiʻoi a me ke komo ʻana o nā mea kiko i nā wahi kai koʻikoʻi.
Paʻa o ka Compression-Fatigue
Hōʻike i ka liʻiliʻi o ke kolo ʻana ma lalo o ke kulou cyclic a me nā ukana compressive, e hāʻawi ana i ke ola lawelawe i ʻoi aku ka maikaʻi ma mua o nā olonā modulus haʻahaʻa e like me ka polyester a i ʻole polypropylene.
