ʻO ka polyethylene ultra-high-molecular-weight (UHMWPE, UHMW) kahi ʻāpana o ka polyethylene thermoplastic.ʻIke pū ʻia ʻo high-modulus polyethylene, (HMPE), a i ʻole polyethylene hana kiʻekiʻe (HPPE), he mau kaulahao lōʻihi loa kona, me ka nui molekala ma waena o 3.5 a me 7.5 miliona amu.ʻO ke kaulahao lōʻihi ka hoʻoili ʻana i ka ukana i ka iwi kuamoʻo polymer ma o ka hoʻoikaika ʻana i nā pilina intermolecular.Loaʻa kēia i kahi mea paʻakikī loa, me ka ikaika hopena kiʻekiʻe loa o kekahi thermoplastic i hana ʻia i kēia manawa.
ʻO kahi ʻāpana o ka polyethylene thermoplastic, ʻo UHMW (aka UHMW-PE) ka mea i ʻike ʻia ma ke ʻano he mea hoʻokahi o nā polymers mana o ke kenekulia 20, ʻo ka UHMW ka lōʻihi a me ka versatility e lilo ia i mea punahele i waena o nā ʻenekinia a me nā mea hoʻolālā ma kahi kokoke i nā ʻoihana āpau o ka honua.ʻO ke kī ʻo ke kaulahao molekala lōʻihi loa o UHMW, ka mea e hāʻawi iā UHMW i nā ʻano hiʻohiʻona ʻokoʻa e like me ke kūpaʻa abrasion kiʻekiʻe, ka haʻahaʻa haʻahaʻa o ka friction a me ke kūpaʻa hopena like ʻole, ʻoiai ma nā wahi cryogenic.Kūpono no ka hoʻohana ʻana i nā noi kahi e pāʻani ai ka lole a me ka friction.ʻO nā ʻoihana e like me ka lawelawe ʻana i nā mea waiwai, ka hana meaʻai, nā kaʻa, ke alahao, ka mahiʻai, ka lāʻau lapaʻau, ka paʻi ʻana a me ka hoʻopili ʻana he nui nā noi kahi e hiki ai i nā uhi UHMW a me nā mea waiwai ke hāʻawi i nā pono a hoʻonui i ka pono a me ka huahana.
ʻO nā māka kūlohelohe a i hoʻoponopono hou ʻia ka mea maʻamau.Ua hoʻololi ʻia ʻo UHMW e hoʻokō i nā koi noi kūikawā ma o ka hoʻopili ʻana me nā mea hoʻohui a me nā mea hoʻopihapiha e hana i nā māka kūikawā a me ka waiwai me ka waiwai i makemake ʻia.Ma lalo iho nei kekahi o nā māka uku maʻamau: ʻO Glass Filled, Cross-linked, UV Stabilized, Static Control: Anti-Static, MoS2 filled, Oil filled, Flame retardant and Heat Stabilized.
NA WAIWAI
MANAʻO: ʻO nā waiwai waiwai i hōʻike ʻia ma luna nei he mau waiwai maʻamau i manaʻo ʻia no ka hoʻohālikelike a me nā kumu hoʻohālikelike wale nō.ʻAʻole pono lākou e hoʻohana ʻia i kumu no nā kikoʻī hoʻolālā a i ʻole ka mana o ka maikaʻi.E hoʻokaʻaʻike mai iā mākou no ka ʻikepili waiwai piha o nā mea hana.ʻO nā waiwai a pau ma 73°F (23°C) ke ʻole i ʻike ʻia.

NA PONO:Paʻa ʻino a ʻaʻahu; Paʻa i ka vibration; Maʻalahi hiki ke machinable; Kūʻē kemika kiʻekiʻe; Ka helu haʻahaʻa o ka friction; ʻO ke kaumaha māmā; ʻO ka mea maʻamau ka FDA a me ka USDA; Ke kūpaʻa abrasion maikaʻi; Ke kūpaʻa ʻana i ka wai; Ke kūpaʻa uila maikaʻi.
