Dyneema (Ultra-high molecular weight polyethylene fiber) Rope

No na kaula UHMW-PE

ʻO Frankstar Dyneema (Ultra-high molecular weight polyethylene fiber) Hoʻohui ke kaula i nā hiʻohiʻona o ke kaumaha māmā a me ka ikaika kiʻekiʻe. ʻOi aku ka haʻahaʻa ma mua o ka wai, e hiki ai ke lana maoli ma luna o ka wai. ʻO ke kaula UHMW-PE kahi mea hana kiʻekiʻe maikaʻi loa no ka moana a me nā kaiapuni ʻino loa. Me kona kūpaʻa kūʻokoʻa o ka wā a me ka paʻa kemika, hiki iā ia ke pale aku i nā pilikia kūlohelohe e like me nā kukui ultraviolet, moisture, a me ka waika a me ka corrosion alkali me ka ʻole o ka mālama ʻana, a hoʻohana nui ʻia i ka ʻenekinia moana, ka ʻimi noiʻi ʻepekema, a me nā ʻoihana ʻoihana.

Nā hiʻohiʻona

Hoʻohana nui ʻia ma nā ʻupena trawl plankton, hiki ke hāʻawi i ka buoyancy static, a ʻoi aku ka haʻahaʻa o ka haʻahaʻa haʻahaʻa ma mua o nā kaula Kevlar.

Ka ikaika kiʻekiʻe: Ma kahi paona no ke kumu paona, ʻo Dyneema he 15 mau manawa ʻoi aku ka ikaika ma mua o ke kaula kila.

Kaumaha Māmā: ʻO ka nui no ka nui, ʻo ke kaula i hana ʻia me Dyneema he 8 mau manawa ma mua o ke kaula uea kila.

Kūleʻa wai: He hydrophobic ʻo Dyneema a ʻaʻole e komo i ka wai, ʻo ia hoʻi e mau ana ka māmā i ka wā e hana ai i nā kūlana pulu.

Ua lana: He 0.97 ko Dyneema, 'o ia ho'i, e lana ana i loko o ka wai ('o ka umekaumaha kiko'ī he ana o ka mānoanoa. He SG ka wai he 1, no laila e lana ana nā mea me SG<1 a me ka SG>1 'o ia ho'i e poho).

Ke kū'ē kemika: ʻAʻole kemika ʻo Dyneema, a hana maikaʻi i nā kūlana maloʻo, pulu, paʻakai a me ka wai, a me nā kūlana ʻē aʻe kahi e loaʻa ai nā mea kemika.

Palena UV: He kū'ē maikaʻi loa ʻo Dyneema i ka hoʻohaʻahaʻa kiʻi, e mālama ana i kāna hana i ka wā e ʻike ʻia ai i ka kukui UV.

ʻO nā waiwai kino o nā fiber polyethylene kiʻekiʻe a me ka modulus kiʻekiʻe he maikaʻi loa. Ma muli o kona crystallinity kiʻekiʻe, he hui kemika ʻaʻole maʻalahi ke hana me nā mea hana kemika. No laila, kū'ē ia i ka wai, ka haʻahaʻa, ka ʻino kino, a me nā kukuna ultraviolet, no laila ʻaʻohe pono e hoʻopaʻa i ka mālama ʻana i ka ultraviolet. ʻO ke kūpaʻa o ka corrosion, ka waikawa a me ke kūpaʻa alkali, ke kūpaʻa abrasion maikaʻi loa, ʻaʻole wale ka modulus kiʻekiʻe, akā palupalu nō hoʻi, he lōʻihi ke ola flexural, ʻo ka helu heheʻe o ke kiʻekiʻe-modulus polyethylene fiber kiʻekiʻe ma waena o 144 ~ 152C, ʻike ʻia i ka 110C kaia no ka manawa pōkole ʻaʻole ia e hoʻohaʻahaʻa i ka hana koʻikoʻi, etc.

ʻĀpana ʻenehana

Mea Hana: ʻO ka fiber polyethylene kaumaha kiʻekiʻe kiʻekiʻe
Hana ʻia: 8-strand a i ʻole 12-strand braid
Anawaena: Loaʻa ma 6, 8, 10, a i ʻole 12 mm
Kala: Keʻokeʻo
Ka lōʻihi o ka ʻōwili: 220m (hiki ke hoʻololi ʻia)
