He aha ka Ultra-High Molecular-Weight Polyethylene (UHMWPE)

ʻO ka polyethylene ka plastic i hoʻohana pinepine ʻia ma ka honua, akā pehea ʻoe e ʻike ai inā ʻo ia ka wili kūpono no kāu noi?E noʻonoʻo i nā hiʻohiʻona o ka polyethylene ultra-high-molecular-weight (UHMWPE) - kahi ʻāpana paʻakikī loa o ka polyethylene i loaʻa ka ikaika i ke kaupaona ʻana he 8-15 manawa ʻoi aku ka nui ma mua o ke kila.

ʻIke mau ʻia e nā inoa kālepa o Spectra® a me Dyneema®, UHMWPE plastics a me nā wili i hoʻohana mua ʻia no:

· Hoʻohana Ballistic (Kōnaʻi Paʻi, Pale ʻAʻahu)

· Nā haʻuki a me nā leʻaleʻa (skydiving, skiing, waʻa, lawaiʻa)

· Nā kaula a me ke kaula

· Ka mālama ʻana i nā mea nui

· Nā ʻāpana porous a me ke kānana

· ʻOihana kaʻa

· ʻOihana Kemika

· Mea hana meaʻai a me nā mīkini inu

· ʻO nā mea hana eli a me nā minerala

· Mea hana hana

· ʻEnekinia Kivila a me nā lako hoʻoneʻe honua

· Nā noi e pili ana i ka lawe ʻana, me nā pā kaʻa, nā pahu a me nā pahu.

E like me kāu e ʻike ai he ʻokoʻa ka hoʻohana ʻana o UHMWPE mai ka hana ʻana i ka lāʻau lapaʻau a me nā noi uea a me nā kelepona.ʻO kēia ma muli o kāna papa inoa lōʻihi o nā pono e kūpono ana i nā koi kūikawā no nā hana like ʻole.

Aia nā pono o UHMWPE, akā ʻaʻole i kaupalena ʻia i:

· Kūleʻa maikaʻi i ke koʻikoʻi a me ke kūpaʻa kiʻekiʻe i ka haki ʻana

· Kūleʻa ʻaʻahu abrasion - 15 mau manawa ʻoi aku ka pale ʻana i ka abrasion ma mua o ke kila kalapona

· ʻOi aku ka ikaika o 40% ma mua o nā wili Aramid

· ʻO kona kūpaʻa kemika ikaika - hiki ke kūpaʻa i ka hapa nui o nā alkalis a me ka waikawa, nā mea hoʻoheheʻe organik, nā mea hoʻoheheʻe a me ka hoʻouka electrolytic.

· ʻAʻohe mea ʻawaʻawa

· Maikaʻi dielectric waiwai

· Lubricating ponoʻī - haʻahaʻa haʻahaʻa loa o ka friction (e like me PTFE)

· Hoʻopaʻa ʻole

· Ua ʻae ʻia ʻo FDA no ka hoʻohana ʻana i ka meaʻai a me nā noi olakino

· Kaumaha kiko haʻahaʻa - e lana i ka wai

ʻOiai e like paha kēia me kahi mea kūpono, aia kekahi mau hemahema e pono ai ʻoe e ʻike.ʻO ka UHMWPE kahi helu heheʻe haʻahaʻa (297° a 305° F) ma mua o nā polymers maʻamau, no laila ʻaʻole kūpono ia no nā noi wela kiʻekiʻe.Loaʻa iā ia kahi coefficient haʻahaʻa o ka friction hiki ke lilo i drawback ma muli o ka noi.Hiki i nā wili UHMWPE ke hoʻomohala i ka "kolo" ma lalo o kahi haʻahaʻa mau, ʻo ia ke kaʻina o ka hoʻolōʻihi ʻia o nā fiber.Manaʻo paha kekahi poʻe he pōʻino ke kumu kūʻai, akā i ka hiki ʻana mai i ka UHMWPE, ʻoi aku ka liʻiliʻi.Ma muli o ka ikaika o kēia mea, ʻaʻole pono ʻoe e kūʻai e like me kou makemake me nā mea ʻē aʻe.
