Nā hiʻohiʻona
1. Hoʻomaikaʻi i ke kūpaʻa ʻana i ka ʻaʻahu. ʻO kekahi o nā waiwai koʻikoʻi o ka polyethylene UHMW ʻo ia kona kūpaʻa kiʻekiʻe loa i ka abrasion, he mea waiwai nui ia i nā noi ʻenekinia he nui. Ma waena o nā plastics āpau, ʻo kona kūpaʻa ʻana i ka ʻaʻahu ka mea maikaʻi loa, a ʻoiai ke kūpaʻa maʻamau o nā mea metala he nui (e like me ke kila kalapona, ke kila kila, ke keleawe, a me nā mea ʻē aʻe) ʻaʻole like ka maikaʻi me ia. I ka piʻi ʻana o ke kaumaha molekala o ka polyethylene, lilo ka mea i mea kūpaʻa i ka ʻaʻahu.
2. Ke kūpaʻa kiʻekiʻe loa i ka hopena. Pili ka ikaika o ka hopena o ka polyethylene kaumaha molekala kiʻekiʻe loa i kona kaumaha molekala. Ke emi ke kaumaha molekala ma mua o 2 miliona, piʻi ka ikaika o ka hopena me ka piʻi ʻana o ke kaumaha molekala, a hiki i ka piko ma kahi o 2 miliona. Ma hope o ka piko, piʻi ka ikaika o ka hopena me ke kaumaha molekala. e emi ana. ʻO kēia no ka mea he ʻano ʻē ke kaulahao molekala a keakea nei i kona photocrystallization, no laila aia kahi ʻāpana amorphous nui i loko o ka macromolecule, hiki ke omo i ka ikehu hopena nui.
3. Ka helu haʻahaʻa o ka friction. He kūpaʻa loa ka UHMWPE i ke komo ʻana, he haʻahaʻa kona coefficient o ka friction a me ka lubrication ponoʻī maikaʻi, a he mea kūpono ia no nā bushings bearing, nā sliders a me nā linings.
ʻO ka hoʻohana ʻana i ka polyethylene kaumaha molekala kiʻekiʻe loa ma ke ʻano he ʻāpana friction o nā lako ʻaʻole hiki ke hoʻomaikaʻi wale i ke ola kūpaʻa i ke komo ʻana, akā mālama pū i ka ikehu.
4. Kū'ē maika'i i nā kemika. Loa'a i ka polyethylene kaumaha molekala ki'eki'e loa ke kū'ē maika'i i ka pala kemika. Koe wale nō ka waikawa nitric i ho'opa'a 'ia a me ka waikawa sulfuric i ho'opa'a 'ia, 'a'ole ia e pala i nā hopena lye a me nā waikawa āpau, a hiki ke ho'ohana 'ia i loko o ka waikawa hydrochloric i ho'opa'a 'ia ma kahi mahana (80°C, He pa'a nō ho'i ia i loko o <20% waikawa nitric, <75% waikawa sulfuric, a he pa'a nō ho'i ia i ka wai, ka holoi wai.)
Eia nō naʻe, he maʻalahi loa ka pehu ʻana o ka polyethylene kaumaha molekala kiʻekiʻe loa i loko o nā hui ʻala a i ʻole nā halogenated (ʻoi aku hoʻi ma lalo o nā kūlana mahana kiʻekiʻe), no laila pono e uku ʻia ka nānā kūikawā i ka wā o ka noi.
5. Haʻahaʻa loa ka omo ʻana o ka wai. He haʻahaʻa loa ka nui o ka omo ʻana o ka wai o ka UHMWPE, aneane ʻaʻole ia e omo, ʻaʻole e pehu i ka wai, a ʻoi aku ka liʻiliʻi o ka omo ʻana ma mua o ka nylon.
6. Nā waiwai wela. Wahi a ke ʻano o ASTM (kaumaha 4.6kg/cm2), ʻo ka mahana hoʻopilikia wela he 85℃. Ma lalo o kahi ukana liʻiliʻi, hiki i ka mahana lawelawe ke piʻi i 90℃. I nā hihia kūikawā, ʻae ʻia e hoʻohana ma kahi mahana kiʻekiʻe. ʻO ka polyethylene kaumaha molekala kiʻekiʻe kahi mea me ka paʻakikī maikaʻi loa, no laila he maikaʻi loa kona kū'ē haʻahaʻa, a loaʻa nō iā ia kekahi kekelē o ka ductility ma ka mahana haʻahaʻa o -269 ° C, a ʻaʻohe hōʻailona o ka embrittlement.
7. Nā waiwai uila. Loaʻa iā UHMWPE nā waiwai uila maikaʻi loa i loko o kahi ākea ākea o ka mahana, ʻo kona pale ʻana i ka leo he 10-18CM, ʻo kona volta haki he 50KV/mm, a ʻo kona dielectric constant he 2.3. I loko o kahi ākea ākea o ka mahana a me ke alapine (frequency), ʻaʻole nui ka loli o kona mau waiwai uila. I loko o ka pae mahana pale wela, kūpono loa ia no ka hoʻohana ʻana ma ke ʻano he mau mea kūkulu i ka ʻenekinia uila a me nā mea i loko o nā wili pepa.
8. ʻO ka polyethylene kaumaha molekala kiʻekiʻe ʻaʻohe ʻona, ʻaʻohe ʻawaʻawa, ʻaʻohe ʻala, ʻaʻohe ʻino, a he hiki ke hoʻololi i ke kaʻina hana a me ke ʻano o ka hana. ʻAe ka United States Food and Drug Administration (FDA) a me ka United States Department of Agriculture (USDA) iā ia e hoʻohana ʻia me ka meaʻai a me nā lāʻau lapaʻau.
ʻO kona mau hiʻohiʻona, ʻoiai ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa i ka hopena, a me nā waiwai lubrication ponoʻī, ʻo ia ka mea maikaʻi loa ma waena o nā plastics ʻenekinia.
