He aha ka PEEK? ʻO kahi loiloi hohonu o kēia polymer hana kiʻekiʻe
ʻO ka Polyetheretherketone (PEEK) kahi mea polymer hana kiʻekiʻe i hoʻokipa nui ʻia i nā ʻoihana like ʻole i nā makahiki i hala. He aha ka PEEK? He aha kona mau waiwai a me kona mau pono? Ma kēia ʻatikala, e pane mākou i kēia nīnau me ka kikoʻī a kūkākūkā i kāna ākea o nā noi ma nā ʻano āpau.
He aha ka mea PEEK?
ʻO PEEK, i kapa ʻia ʻo Polyether Ether Ketone (Polyether Ether Ketone), he semi-crystalline thermoplastic engineering plastic me nā waiwai kūʻokoʻa. Aia ia i ka ʻohana polyaryl ether ketone (PAEK) o nā polymers, a ʻoi aku ka PEEK i ke koi ʻana i nā noi ʻenekinia ma muli o kāna mau ʻano mechanical maikaʻi loa, ke kūpaʻa kemika a me ke kūpaʻa wela kiʻekiʻe. Loaʻa i kāna ʻano molekala nā apo ʻala ʻono a me nā paʻa ether a me ketone hiki ke hoʻololi, hāʻawi iā ia i ka ikaika a me ka paʻakikī.
Nā waiwai nui o nā mea PEEK
ʻOi aku ka maikaʻi o ka pale ʻana i ka wela kiʻekiʻe: ʻO ka PEEK kahi wela wela (HDT) o 300 ° C a ʻoi aʻe paha, e hiki ai iā ia ke mālama i nā waiwai mechanical maikaʻi loa i nā wahi wela kiʻekiʻe. Hoʻohālikelike ʻia me nā mea thermoplastic ʻē aʻe, ʻoi aku ka maikaʻi o ka paʻa ʻana o PEEK i nā wela kiʻekiʻe.

ʻO ka ikaika mechanical maikaʻi loa: ʻO PEEK ka ikaika tensile kiʻekiʻe loa, rigidity a me ka paʻakikī, a mālama i ka paʻa o ka dimensional maikaʻi a hiki i nā wela kiʻekiʻe. ʻO kona pale ʻana i ka luhi e hiki ai iā ia ke ʻoi aku i nā noi e koi ana i ka lōʻihi o ka ʻike ʻana i ke koʻikoʻi mechanical.

Kūleʻa kemika maikaʻi loa: Kūleʻa nui ʻo PEEK i kahi ākea o nā kemika, me nā ʻakika, nā kumu, nā solvents a me nā aila. ʻO ka hiki i nā mea PEEK ke mālama i ko lākou hoʻolālā a me nā waiwai i nā manawa lōʻihi i nā wahi kemika koʻikoʻi ua alakaʻi i kahi ākea o nā noi i ka ʻoihana kemika, aila a me ke kinoea.

ʻO ka uahi haʻahaʻa a me nā mea ʻawaʻawa: Hoʻopuka ka PEEK i nā haʻahaʻa haʻahaʻa o ka uahi a me nā mea ʻawaʻawa ke puhi ʻia, e kaulana loa ia ma nā wahi e koi ʻia ai nā kūlana palekana koʻikoʻi, e like me ka aerospace a me ke kaʻa kaʻa.

Nā wahi noi no nā mea PEEK

Aerospace: Ma muli o kona ikaika kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka mahana a me nā waiwai māmā, hoʻohana ʻia ʻo PEEK i kahi ākea o nā noi e like me nā mokulele mokulele, nā ʻāpana ʻenekini a me nā mea hoʻohui uila, e hoʻololi ana i nā mea metala kuʻuna, e hōʻemi i ke kaumaha holoʻokoʻa a me ka hoʻomaikaʻi ʻana i ka wahie.

Nā lāʻau lapaʻau: He biocompatibility maikaʻi ko PEEK a hoʻohana mau ʻia i ka hana ʻana i nā implants orthopedic, nā mea niho a me nā mea hana ʻoki. Hoʻohālikelike ʻia me nā implants metala maʻamau, ʻoi aku ka maikaʻi o ka radiopacity a me ka liʻiliʻi o nā hopena maʻi.

Uila a me Electronics: ʻO ka PEEK ka wela a me ka uila insulating waiwai i mea kūpono no ka hana ʻana i nā mea hoʻohui uila hana kiʻekiʻe, nā ʻāpana insulating, a me nā lako hana semiconductor.
Automotive: Ma kaʻoihana kaʻa, hoʻohanaʻia ka PEEK e hana i nā mea mīkini, nā bearings, nā sila, a me nā mea'ē aʻe. Pono kēia mau mea i ke ola lōʻihi a me ka hilinaʻi i nā wela kiʻekiʻe a me nā kaomi, a hoʻokō nā mea PEEK i kēia mau pono.

Nā Manaʻo e hiki mai ana no nā mea PEEK

Ke hoʻomau nei ka ʻenehana i ka holomua, e hoʻonui hou ka laulā o nā noi no PEEK. ʻOi aku ma ke kahua o ka hana kiʻekiʻe, ka ʻenehana lapaʻau a me ka hoʻomohala hoʻomau, ʻo PEEK me kāna mau pono hana kūʻokoʻa, e pāʻani i kahi hana koʻikoʻi. No nā ʻoihana a me nā keʻena noiʻi, ʻo ka ʻike hohonu o ka PEEK a me kāna mau noi pili e kōkua i ka hopu ʻana i nā manawa mākeke e hiki mai ana.
Ma ke ʻano he mea polymer hana kiʻekiʻe, ua lilo ʻo PEEK i mea koʻikoʻi o ka ʻoihana hou ma muli o kāna hana maikaʻi loa a me ka laulā o nā noi noi. Inā ʻoe e noʻonoʻo nei e pili ana i ka PEEK, manaʻolana ua hāʻawi kēia ʻatikala iā ʻoe i kahi pane maopopo a piha.
