Kaula Ulana Polyethylene Kaumaha Molekala Kiʻekiʻe Loa

Ma ke ʻano he loea i ka ʻoihana lako Marine, ua kākoʻo ʻo Alastin Marine i nā mea kūʻai aku a puni ka honua me nā huahana kiʻekiʻe.

I kēia lā, ke hoʻolauna nei mākou i ke kaula ulana polyethylene kaumaha molekala kiʻekiʻe loa. Ua ʻike ʻia hoʻi ʻo "UHMWPE".

1. Ikaika kiʻekiʻe: ʻo ka ikaika he 10 manawa o ke kila kiʻekiʻe.

2. Modulus kiʻekiʻe: ʻo ka lua wale nō i ka fiber kalapona super.

3. Haʻahaʻa ka nui: emi ma mua o ka wai, hiki ke lana ma luna o ka ʻili.

He gene kemika, ma muli o kona crystallinity kiʻekiʻe, ʻaʻole ia e pane maʻalahi me nā mea hana kūpono i ke kumukūʻai. No laila, ke kūpaʻa wai, kūpaʻa makū, kūpaʻa corrosion kemika, kūpaʻa UV, no laila ʻaʻohe pono e hana i ka mālama ʻana i ke kūpaʻa UV.

Ke kūpaʻa ʻana i ka ʻino, ke kūpaʻa waikawa a me ka alkali, me ke kūpaʻa ʻaʻahu maikaʻi loa.

ʻO ka ikaika kiʻekiʻe a me ke kaula polyethylene modulus kiʻekiʻe ka mea e kū'ē ai i ka mahana haʻahaʻa kiʻekiʻe loa o 200℃a me ke kūpaʻa wela kiʻekiʻe o 120-152℃.

Inā pono ʻoe e hoʻohana i ia mau huahana i ka lawaiʻa a i ʻole ka ʻoihana, e ʻoluʻolu e leka uila maikāhea iā mā˚ou.
