ʻO UHMWPE ke kū nei no Ultra-High Molecular Weight Polyethylene, he ʻano polymer thermoplastic. Ua kaulana ia no kona kūpaʻa kiʻekiʻe i ka ʻaʻahu, ka haʻahaʻa o ka friction, a me ka ikaika hopena kiʻekiʻe, e kūpono ana no nā ʻano hana like ʻole.

Ma ke ʻano o ke komo ʻana, ua ʻike ʻia ʻo UHMWPE no kona kūpaʻa maikaʻi loa i ke komo ʻana, ma muli o kona kaumaha molekala kiʻekiʻe a me ke ʻano kaulahao lōʻihi. ʻO kēia ka mea e lilo ai ia i koho kaulana no nā ʻāpana i kau ʻia i nā pae kiʻekiʻe o ke komo ʻana, e like me nā ʻōnaehana conveyor, nā kia, a me nā bearings. Hoʻohana ʻia ʻo UHMWPE i nā uhi a me nā linings pale i ke komo ʻana no nā paipu, nā pahu, a me nā chutes.

Ma waho aʻe o kona kūpaʻa ʻana i ka ʻaʻahu, loaʻa iā UHMWPE nā waiwai ʻē aʻe e lilo ai ia i koho kaulana i nā ʻoihana like ʻole. He kūpaʻa ia i nā kemika, he haʻahaʻa ka coefficient o ka friction, a ʻaʻohe mea ʻawahia a ua ʻae ʻia e ka FDA no ka hoʻohana ʻana i nā noi hana meaʻai.

Ma keʻano holoʻokoʻa, he mea kūpono ʻo UHMWPE no nā noi kahi e noʻonoʻo nui ai ke kūpaʻa ʻana i ka ʻaʻahu, ka haʻahaʻa o ka friction, a me ka ikaika o ka hopena.

ʻO UHMWPE ke kū nei no ka polyethylene kaumaha molekala kiʻekiʻe loa, ʻo ia kekahi ʻano polymer thermoplastic. Ua kaulana ia no kona kūpaʻa kiʻekiʻe i ka abrasion, ka ikaika hopena, a me nā waiwai friction haʻahaʻa, e lilo ia i mea kūpono no nā noi komo.

Ma ke ʻano o ke komo ʻana, hoʻohana pinepine ʻia ʻo UHMWPE e hana i nā mea e like me:

• Nā laina no nā hoppers, nā chutes, a me nā silos e hōʻemi i ka hōʻiliʻili ʻana o nā mea a hoʻonui i ke kahe ʻana o nā mea
• ʻO nā ʻōnaehana conveyor a me ke kāʻei e hōʻemi i ka friction a me ke komo ʻana ma nā ʻāpana
• E kau i nā papa, e kau i nā ʻāpana, a e kau i nā ʻāpana no nā mīkini a me nā lako
• Nā kumu ski a me ka snowboard no ka hoʻomaikaʻi ʻana i ka glide a me ke kūpaʻa
• Nā mea hoʻokomo lāʻau lapaʻau a me nā mea hana, e like me ke kuli a me ke pani ʻūhā, no ko lākou biocompatibility a me ke kūpaʻa ʻana i ka ʻaʻahu

ʻOi aku ka makemake o UHMWPE ma mua o nā mea ʻē aʻe e like me ke kila, ka alumini, a me nā mea ʻē aʻenā lymers ma muli o kona hui pū ʻana o ke kūpaʻa ʻana i ka ʻaʻahu, ka haʻahaʻa o ka friction, a me ke kaumaha māmā. Eia kekahi, kūpaʻa ʻo UHMWPE i nā ʻano kemika like ʻole a me ka radiation UV, e kūpono ai no ka hoʻohana ʻana i nā wahi ʻino.
