Ke kaula Dyneema/Ka ikaika kiʻekiʻe/Modulus kiʻekiʻe/Ka haʻahaʻa haʻahaʻa

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 ia ke ana o ka umekaumaha. He SG ko ka wai. .

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 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, he lōʻihi ke ola flexural, ʻo ka helu heheʻe o ke kiʻekiʻe kiʻekiʻe-modulus polyethylene fiber ma waena o 144 ~ 152C, hōʻike ʻia i ka honua 110C no ka manawa pōkole ʻaʻole ia e hoʻohaʻahaʻa i ka hana koʻikoʻi, etc
