He aha ka PEEK?

ʻO ka Polyether ether ketone (Poly-ether-ether-ketone, PEEK no ka pōkole) he ʻano mea polymer kūikawā i haku ʻia me nā ʻāpana i hana hou ʻia e loaʻa ana ʻelua mau pilina ether a me hoʻokahi pilina ketone i loko o ke kaulahao nui. He moʻo mea ia o ka polyether ketone. Loaʻa iā ia nā ʻano o ke kūlana kristal semi-knot, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa i ka pala kemika a pēlā aku.

Nā ʻano o PEEK

ʻO Polyether ether ketone (PEEK) wale nō ke ʻano o ka mea polyaryl ether ketone (PAEK) i hiki ke hana nui ʻia. ʻO PEEK, ma ke ʻano he plastic ʻenekinia kūikawā, he mau waiwai piha maikaʻi loa.
Nā hiʻohiʻona maʻamau o PEEK:
(1) Ka Hana: Loaʻa i ka resin PEEK nā pono o ke kahe ʻana o ka mahana kiʻekiʻe a me ka mahana decomposition wela kiʻekiʻe. Hiki ke hana ʻia ma ke ʻano injection molding, extrusion molding, molding, blow molding, melting spinning, rotary molding a me ka pauka spraying, etc.

(2) Ke kū'ē ʻana i ka radiation: me ke kūpaʻa ikaika o ka radiation, hiki ke mālama ʻia nā waiwai mechanical ma lalo o nā kukuna γ kiʻekiʻe, ʻoi aku ka nui ma mua o ka polystyrene kūpaʻa radiation maikaʻi loa ma ka resin maʻamau, hiki ke hoʻohana ʻia ma ke ʻano he mau ʻāpana pale radiation i nā lako nukelea.

(3) Mea pale ahi: Loaʻa iā PEEK ka hoʻopau ponoʻī ʻana, ʻoiai me ka ʻole o ka mea pale ahi, a hiki i ka pae UL maʻamau 94V-0.

(4) Ke kū'ē ʻana i ke kolo: ma lalo o ka hana o ke kaumaha mau, e hoʻololi mau ka mea i loko o ke kolo i loko o kekahi manawa. ʻO PEEK ka mea kū'ē kolo maikaʻi loa o ka resin thermoplastic.

(5) Paʻakikī a me ka paʻakikī: me ka ikaika tensile kiʻekiʻe, ka ikaika haki koʻikoʻi kiʻekiʻe, ʻoi aku hoʻi no ka pale ʻana i ka luhi koʻikoʻi he mea kupaianaha loa ia, e like me nā mea hao.

(6) Lubrication ponoʻī (pale ʻaʻahu): Loaʻa iā PEEK nā ʻano paheʻe maikaʻi loa, kūpono no nā koi koʻikoʻi o ka coefficient friction haʻahaʻa a me nā noi pale ʻaʻahu; Ma ke ʻano kūikawā, ʻo PEEK i hoʻololi ʻia me ke kalapona fiber, graphite a me PTFE he pale ʻaʻahu maikaʻi loa.

(7) Ke kū'ē wela kiʻekiʻe: Loaʻa iā PEEK ka mahana hoʻololi aniani kiʻekiʻe (Tg = 143 ℃) a me ka wahi hoʻoheheʻe (Tm = 334 ℃), ʻo kona mahana hoʻololi wela a hiki i ka 316 ℃, ʻo ka mahana lawelawe lōʻihi he 260 ℃, hiki i ka mahana lawelawe koke ke hiki i ka 300 ℃, ma lalo o ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe no ka manawa lōʻihi me ka ʻole o ka nalowale o nā waiwai kino.

(8) Ke kū'ē ʻana i ka hydrolysis: Hiki i nā huahana PEEK ke hoʻomau i ka hana no nā tausani hola me ka ʻole o ka hōʻino ʻana o ka hana i ka mahu 260℃ a i ʻole ke komo ʻana i ka wai kiʻekiʻe; ʻO PEEK ka pale maikaʻi loa i ka hydrolysis a me ka mahu ma waena o nā plastics ʻenekinia āpau.

(9) ʻAʻohe ʻawahia: hiki ke hoʻohana ʻia i ka hoʻomaʻemaʻe meaʻai, nā lako lapaʻau a me nā kahua ʻē aʻe.

(10) Ke kūpaʻa ʻana i ka palaho: Koe wale nō ka waikawa sulfuric i hoʻopaʻa ʻia, ʻaʻole hiki ke hoʻoheheʻe ʻia ʻo PEEK i loko o kekahi mea hoʻoheheʻe a me ka waikawa ikaika a me ka alkali, me ke kūpaʻa kemika kiʻekiʻe.

(11) Ke kū'ē i ka luhi: ʻO PEEK ka mea kū'ē maikaʻi loa i ka luhi ma waena o nā mea resin thermoplastic āpau.

Ka hoʻohana ʻana o PEEK

ʻO ka resin Polyether ether ketone (PEEK) kahi ʻano hana maikaʻi loa o nā plastics ʻenekinia kūikawā, he nui nā pono koʻikoʻi i hoʻohālikelike ʻia me nā plastics ʻenekinia kūikawā ʻē aʻe, ke kūpaʻa wela kiʻekiʻe, hana mechanical maikaʻi, lubrication ponoʻī, kūpaʻa i ka corrosion kemika, pale lapalapa, kūpaʻa stripping, kūpaʻa radiation, kūpaʻa insulation, kūpaʻa hydrolysis a me ka hana maʻalahi, a pēlā aku, hoʻohana nui ʻia i ka ʻoihana lapaʻau.

Hiki i ka resin PEEK ke kū i 3000 mau pōʻaiapuni o ka autoclaving ma 134 ° C, kahi e kūpono ai no ka hana ʻana i nā lako hana ʻokiʻoki a me nā niho i hoʻomaʻemaʻe nui ʻia e pono ai ka hoʻohana hou ʻana. ʻAʻole wale nā ​​​​pono o PEEK o ke kaumaha māmā, ʻaʻohe ʻawahia a me ke kūpaʻa i ka pala, akā loaʻa pū kekahi mau ʻano o ka modulus elastic o ka iwi cortical kanaka, hiki ke hoʻohui ʻia me ke kino. No laila, ʻo ka hoʻohana ʻana i ka resin PEEK ma kahi o ka metala e hana i nā iwi kanaka he mea nui ia i ke kahua lapaʻau.

Ua hoʻohana mua ʻia ʻo PEEK ma ke keʻena lapaʻau i ka makahiki 1999. Mai ia manawa, ʻoi aku ma mua o ʻelima milionaNā huahana PEEKua hoʻokomo ʻia i loko o kānaka, e lilo ana ia i kūlana gula i ka hoʻohui ʻana o ka iwi kuamoʻo. I nā makahiki i hala iho nei, ua hoʻomaikaʻi ʻia ʻo PEEK ʻo ia ka "mea kūpono no ka hanauna hou o nā huahana lapaʻau implantable".

He aha nā ʻano implants i hana ʻia mai PEEK?
（1）nā pani iwi, nā mea hoʻokomo iwi maxillofacial
（2）ʻoki ʻana i ka iwi kuamoʻo, hoʻohuihui waena o ka iwi kuamoʻo
（3）a me nā pani iwi ʻūhā, nā mea hoʻokomo hui
（4）nā lako orthopedic: ka papa paʻa a me nā wili
（5）pani niho CFR - PEEK - i hana ʻia me nā mea hoʻokomo niho, nā niho kuʻi, ka paʻa ʻana o ke aʻa
（6） i ke ʻoki puʻuwai, nā pamu a me nā valves o ka puʻuwai

ʻO wai nā ʻoihana ma ka honua e hiki ke hana i ka implant PEEK lōʻihi? Hana ʻia ʻo Peek-optima e Invibio, ka mahele biomaterials o Victrex ma UK.PEEK;

(1) ʻO ka mea PEEK i hoʻokomo ʻia i hoʻokuʻu ʻia i ka mākeke i kēia manawa he pono monopoly loa ia ma ka mākeke honua.
(2) Ua hoʻokuʻu ʻo Belgium Solvay i ka mea PEEK implant-grade zenIVa-PEEK i ka makahiki 2009.
(3) Ua komo ʻo Evonik mai Kelemania i ka mākeke Kina i ka hoʻomaka ʻana o 2014 me ka inoa huahana: VESTAKEEP PEEK.
(4) Ua hoʻokuʻu ʻo Guangzhou Jusheng Medical Technology Co., LTD., ka mea hana wale nō me ka mea PEEK pae implant ma Kina, i ka PEEK pae implant JS-S1 me ka inoa inoa NATUREGEN a me ka papa inoa inoa JS-S1.

Ka mōʻaukala o PEEK

Ka wā hoʻoulu mua (1978-1992):

He palaki ʻenekinia kūikawā hana kiʻekiʻe loa ʻo PEEK i hoʻomohala ʻia e ICI i ka makahiki 1978. Ua noi ʻo ICI no ka palapala Sila Nui a hoʻolilo iā ia i ʻoihana, me ka hiki ke hana he 1000 tons i kēlā me kēia makahiki, kahi i hoʻohana nui ʻia i ka ʻoihana pale kaua.

Ka Hoʻomohala ʻana a me ka Hiolo ʻana o ka Monopoly (1993-2004):

Ua loaʻa iā Victrex ka ʻoihana PEEK mai ICI, e hōʻike ana i kahi ʻano hoʻomohala monopoly, a hoʻonui mau i ka pae hana. I ka makahiki 2003, ua piʻi ka mana hana makahiki i 2800 tons. Ma hope mai, ua hoʻomohala ʻia nā huahana like e DuPont, BASF, Mitsui Tosei Chemical Company o Iapana, a me Telep o ʻAmelika Hui Pū ʻIa. Ua hoʻonui ʻia ʻo PEEK mai kāna mau noi koa mua i nā noi ʻoihana a me nā biomedical.

No ka manawa lōʻihi, ua helu ʻia ʻo PEEK ma ke ʻano he mau mea hoʻolālā no ke ālai ʻana a me ka pāpā ʻana o Kina e ke Kōmike Hoʻonohonoho o Paris. I mea e hoʻokō ai i nā pono o ka pale kaua aupuni a me ka hoʻomohala ʻenehana kiʻekiʻe kīwila, ua hoʻokomo ke aupuni iā ​​ia i loko o nā papahana noiʻi ʻepekema a me ka ʻenehana koʻikoʻi o ka ʻāina mai ka Hoʻolālā ʻelima makahiki ʻehiku a i ka Hoʻolālā ʻelima makahiki ʻumi a me ka Hoʻolālā 863 no ka noiʻi. Ma lalo o ke kākoʻo ikaika o nā kulekele o Kina, ua hoʻomohala kūʻokoʻa ka hui a Polofesa Wu Zhongwen o ke Kulanui ʻo Jilin i ka ʻenehana patent PEEK me nā kuleana waiwai noʻonoʻo kūʻokoʻa a hoʻokumu iā Jida High-tech Materials Co., LTD., i hoʻokomo ʻia i ka hana.

Kahua Hoʻomohala Holoʻokoʻa (2005-i kēia manawa):

I ka makahiki 2005, ua loaʻa iā Evonik ka ʻoihana PEEK o Garda o India, a ua loaʻa iā Solvay ka ʻoihana PEEK. I ka makahiki 2009, ua komo ʻo Jinfa Technology Co., LTD. o Kina, ʻo Panjin Zhongrun Special Plastic Co., Ltd. a me nā ʻoihana ʻē aʻe i ke kahua, a ua komo ʻo PEEK i ke kahua o ka hoʻomohala holoʻokoʻa. Eia kekahi, ke ulu mālie nei ka hoʻololi ʻana o ka ʻenehana composite a me ka hana ʻana o PEEK, a ke hoʻonui nei hoʻi ke kahua noi. Ma muli o ka nui o nā mea hana loea i ka hana ʻana o PEEK a puni ka honua, e lilo ana ke ʻano o ka hoʻokūkū mākeke i mea wela. I kēia manawa, ʻo Wiggs, Solvay lāua ʻo Evonik nā mea hana PEEK nui ʻekolu ma ka honua.
