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 ke kaumaha no ke kumu kaumaha,ʻO Dyneemaʻoi aku ka ikaika o 15 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

Hana ʻia nā kaula ʻo Dyneema me nā fiber polyethylene ikaika kiʻekiʻe ʻo Dyneema, a laila hoʻoikaika ʻia me ke kaʻina kino kaula e hana i kahi kaula ultra-smooth a paʻakikī. Ua hoʻohui ʻia ka mea lubrication i ka ʻili o ke kaula, e hoʻomaikaʻi ana i ka uhi ʻana o ke kaula. Hāʻawi ka uhi ʻoluʻolu i ka lōʻihi o ke kaula a me nā kala lōʻihi, e pale ana i ka abrasion a me ka mae. ʻO ka ikaika kiʻekiʻe, nā fibers polyethylene modulus kiʻekiʻe he mau waiwai kino maikaʻi. Ma muli o kona crystallinity kiʻekiʻe a me nā pūʻulu kemika non-reactive, kūʻē ia i ka wai, ka makū, nā kemika a me nā kinikona. No laila ke kūpaʻa nei i ka wai, ka haʻahaʻa, nā kemika a me nā kukui ultraviolet, a no laila ʻaʻole pono e mālama ʻia no ka pale ʻana o UV. ʻO ke kūpaʻa ʻana o ka corrosion, ka waikawa a me ke kūpaʻa alkali, ke kūpaʻa abrasion maikaʻi loa, ʻaʻole wale ka modulus kiʻekiʻe, akā palupalu nō hoʻi, lōʻihi ke ola lōʻihi, ikaika kiʻekiʻe modulus polyethylene fiber melting point ma waena o 144 ~ 152C, ʻaʻole e hoʻohaʻahaʻa ʻia ka manawa pōkole i ke kaiapuni o 110C.
