ʻO nā waiwai maikaʻi o ka fiber UHMWPE

He nui nā waiwai maikaʻi o ka UHMWPE fiber, e like me nā waiwai mechanical maikaʻi loa, ke kūpaʻa hopena maikaʻi loa, ka pale ʻana i ka lole maikaʻi, ke kūpaʻa kino kino, ka pale māmā maikaʻi a pēlā aku.

1. ʻO nā mea mechanical maikaʻi loa o ka fiber UHMWPE.

Loaʻa i ka fiber UHMWPE nā waiwai mechanical maikaʻi loa. Ma lalo o ka laina laina like, ʻo ka ikaika tensile o ka fiber UHMWPE he 15 mau manawa o ke kaula uea kila. He 40% kiʻekiʻe aʻe ma mua o ka fiber aramid, ʻo ia kekahi o nā fibers ʻenehana kiʻekiʻe ʻekolu o ka honua, a he 10 mau manawa kiʻekiʻe ma mua o ka fiber kila kiʻekiʻe a me ka fiber kemikal maʻamau. Ke hoʻohālikelikeʻia me ke kila, E-glass, nylon, polyamine, carbon fiber a me ka boron fiber,ʻoi aku ka kiʻekiʻe o kona ikaika a me ka modulus ma mua o kēia mau fibers, aʻo kona ikaika ka mea kiʻekiʻe loa ma waena o nā mea like.

2.Excellent hopena kū'ē o UHMWPE fiber

ʻO ka fiber polyethylene paona kiʻekiʻe kiʻekiʻe ka hopena maikaʻi loa. ʻO kona hiki ke komo i ka ikehu a pale aku i ka hopena i ka wā deformation a me ka hoʻoheheʻe ʻana ʻoi aku ka kiʻekiʻe ma mua o ka aramid fiber a me ka carbon fiber, ʻo ia hoʻi nā "ʻekolu fibers kiʻekiʻe o ka honua". Ke hoʻohālikelike ʻia me ka polyamide, aramid, E glass fiber, carbon fiber a me aramid fiber, ʻoi aku ka nui o ka hoʻohana ʻana o ka ikehu i ka UHMWPE fiber ma mua o ka hopena.

3. ʻO ke kūpaʻa maikaʻi loa o ka UHMWPE fiber

ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o ka modulus o ka mea, ʻoi aku ka haʻahaʻa o ka pale ʻana, akā no ka UHMWPE fiber, he ʻoiaʻiʻo. No ka mea, he haʻahaʻa haʻahaʻa ko UHMWPE fiber, ʻoi aku ka nui o ka modulus, ʻoi aku ka kiʻekiʻe o ka pale ʻana. I ka hoʻohālikelike ʻana i ka heluna friction o ka fiber UHMWPE me ka fiber carbon a me ka fiber aramid, ʻoi aku ka kiʻekiʻe o ke kūpaʻa a me ka luhi ʻana o ka fiber UHMWPE ma mua o ka fiber carbon a me ka fiber aramid. No laila ʻoi aku ka maikaʻi o kona pale ʻana ma mua o nā fibers hana kiʻekiʻe. Ma muli o kona kūpaʻa maikaʻi a me ke kūlou ʻana, ʻoi aku ka maikaʻi o kāna hana ʻana, a maʻalahi ke hana ʻia i nā mea hana a me nā lole.

4.Chemical corrosion kū'ē o UHMWPE fiber

He mea maʻalahi ka hana kemika o ka fiber UHMWPE a paʻa kona mau waiwai. Eia kekahi, loaʻa iā ia kahi hoʻonohonoho hoʻonohonoho crystalline nui, e hoʻohaʻahaʻa i ka hoʻouka ʻana o nā genes ikaika i loko o nā waikawa ikaika a me nā kumu ikaika, a hiki ke mālama i kāna mau waiwai a me kona ʻano. No laila, ʻaʻole maʻalahi ka ʻino ʻana o ka hapa nui o nā mea kemika. Hiki i kekahi mau mea hoʻoheheʻe organik ke pehu iki, a ʻoi aku ka liʻiliʻi o kāna waiwai mechanical ma mua o 10%. Ua hoʻohālikelike ʻia ka paʻa ikaika o ka UHMWPE fiber a me ka aramid fiber i loko o nā media kemika like ʻole. ʻOi aku ka kiʻekiʻe o ka pale corrosion o ka fiber UHMWPE ma mua o ka fiber aramid. Paʻa loa ia i ka waikawa, ka alkali a me ka paʻakai, a nalowale kona ikaika i ka solution sodium hypochlorite.

5.Excellent māmā kū'ē o UHMWPE fiber

Ma muli o ka paʻa o ke kinona o ka fiber UHMWPE, ʻoi aku ka maikaʻi o kona kūpaʻa māmā ma waena o nā fibers kiʻekiʻe. ʻAʻole pale ʻo Aramid fiber a hiki ke hoʻohana ʻia ma lalo o ke ʻano o ka pale ʻana i ka lā pololei. Ke hoʻohālikelike nei i ka fiber UHMWPE me ka nylon, aramid me ka modulus kiʻekiʻe a me ka modulus haʻahaʻa, ʻoi aku ka kiʻekiʻe o ka paʻa ʻana o ka fiber UHMWPE ma mua o nā mea ʻē aʻe.

6. ʻO nā waiwai ʻē aʻe o ka fiber UHMWPE

ʻO ka UHMWPE fiber ka waiwai hydrophobic maikaʻi, ka wai a me ke kūpaʻa wai, ka waiwai insulation uila a me ke ola tortuous lōʻihi. ʻO ia wale nō ka fiber ʻenehana kiʻekiʻe e hiki ke lana ma luna o ka wai, a he mea haʻahaʻa haʻahaʻa kūpono hoʻi ia.

Aia nō naʻe kona mau hemahema, ʻo ia hoʻi, he haʻahaʻa ka helu heheʻe. I ka wā o ka hana ʻana, ʻaʻole e ʻoi aku ka mahana ma mua o 130 ℃, inā ʻaʻole, e kū mai ka hanana kolo a e pōkole ke ola lawelawe ma muli o ka ikaika nāwaliwali ma waena o nā kaulahao mole o nā UHMWPE fibers. ʻAʻohe pūʻulu kala ma ka UHMWPE fiber, kahi e hōʻemi ai i ka pulu. He mea paʻakikī ke komo ʻana o ke kala i loko o ka fiber, e hopena i ka maikaʻi ʻole o ka hana kala. Hoʻopili kēia mau hemahema i ka laulā o kāna noi.
