Kū ʻo UHMWPE no Ultra-High Molecular Weight Polyethylene, ʻo ia ke ʻano o ka polymer thermoplastic. ʻIke ʻia ʻo ia no kona kūpaʻa ʻaʻahu kiʻekiʻe, ka haʻahaʻa haʻahaʻa, a me ka ikaika hopena kiʻekiʻe, e kūpono ana ia no ka nui o nā noi.

Ma ke ʻano o ka ʻaʻahu, ʻike ʻia ʻo UHMWPE no kona kūpaʻa maikaʻi loa, ʻo ia ke kumu o kona kaumaha molekala kiʻekiʻe a me ke kaulahao lōʻihi. ʻO kēia ka mea i koho nui ʻia no nā ʻāpana i kau ʻia i nā pae kiʻekiʻe o ka lole, e like me nā ʻōnaehana conveyor, gears, a me nā bearings. Hoʻohana pū ʻia ʻo UHMWPE i nā pale lole a me nā linings no nā paipu, nā pahu, a me nā chutes.

Ma waho aʻe o kona pale ʻana i ka ʻaʻahu, loaʻa iā UHMWPE nā waiwai ʻē aʻe i koho nui ʻia i nā ʻoihana like ʻole. He pale kemika, he haʻahaʻa haʻahaʻa o ka friction, a ʻaʻohe mea ʻawaʻawa a ʻae ʻia ʻo FDA no ka hoʻohana ʻana i nā noi hoʻoponopono meaʻai.

Ma ke ʻano holoʻokoʻa, ʻo UHMWPE kahi mea kūpono no nā noi kahi e noʻonoʻo nui ai ke kūpaʻa ʻana, ka haʻahaʻa haʻahaʻa, a me ka ikaika hopena.

ʻO ka UHMWPE ke kū nei no ka polyethylene kaumaha nui loa, ʻo ia ke ʻano o ka polymer thermoplastic. Ua ʻike ʻia no kona kūpaʻa abrasion kiʻekiʻe, ka ikaika hopena, a me nā waiwai friction haʻahaʻa, e lilo ia i mea kūpono no ka hoʻohana ʻana i nā noi.

Ma ka pōʻaiapili o ka lole, hoʻohana mau ʻia ʻo UHMWPE e hana i nā mea e like me:

• ʻO nā laina laina no nā hoppers, chutes, a me nā silos e hōʻemi i ke kūkulu ʻana i nā mea a hoʻonui i ke kahe waiwai
• ʻO nā ʻōnaehana conveyor a me ke kāʻei e hōʻemi i ka friction a me ke komo ʻana i nā ʻāpana
• E hoʻohana i nā papa, e ʻaʻahu i nā ʻāpana, a me nā ʻāpana no nā mīkini a me nā mea hana
• Nā kumu ski a me ka papa hau no ka hoʻomaikaʻi ʻana i ka holo a me ka lōʻihi
• ʻO nā implants lapaʻau a me nā mea hana, e like me ke kuli a me nā pani pani, no ko lākou biocompatibility a me ke kūpaʻa ʻana

ʻOi pinepine ʻia ka UHMWPE ma mua o nā mea ʻē aʻe e like me ke kila, aluminika, a me nā polymers ma muli o kona hui pū ʻana o ke kūpale ʻaʻahu, ka haʻahaʻa haʻahaʻa, a me ke kaumaha māmā. Hoʻohui ʻia, kūpaʻa ʻo UHMWPE i kahi ākea o nā kemika a me ka radiation UV, kūpono ia no ka hoʻohana ʻana i nā wahi paʻakikī.
