Waa maxay PEEK?

Ketone-ka Polyether ether (Poly-ether-ketone, PEEK marka la soo gaabiyo) waa nooc ka mid ah walxaha polymer-ka gaarka ah oo ka kooban cutubyo soo noqnoqda oo ka kooban laba xidhmo ether iyo hal xidhmo ketone ah oo ku jira qaab-dhismeedka silsiladda ugu weyn. Waa taxane walxo ah oo ketone polyether ah. Waxay leedahay astaamaha xaaladda kiristaalka nus-guntin, iska caabbinta heerkulka sare, iska caabbinta daxalka kiimikada iyo wixii la mid ah.

Astaamaha PEEK

Ketone-ka Polyether ether (PEEK) hadda waa nooca kaliya ee walxaha polyaryl ether ketone (PAEK) ee si ballaaran loo soo saari karo. PEEK, oo ah balaastik injineernimo gaar ah, wuxuu leeyahay sifooyin dhammaystiran oo heer sare ah.
Astaamaha caadiga ah ee PEEK:

Adeegsiga PEEK

Resin Polyether ether ketone (PEEK) waa nooc ka mid ah waxqabadka aadka u fiican ee balaastikada injineernimada gaarka ah, tiro badan oo faa'iidooyin muhiim ah marka la barbar dhigo balaastikada injineernimada gaarka ah ee kale, iska caabbinta heerkulka sare, waxqabadka farsamada wanaagsan, saliidaynta is-nadiifinta, iska caabbinta daxalka kiimikada, daxalka ololka, iska caabbinta xoqidda, iska caabbinta shucaaca, xasilloonida dahaarka, iska caabbinta hydrolysis iyo habaynta fudud, iwm., oo si ballaaran loogu isticmaalo goobta caafimaadka.

Resin PEEK wuxuu u adkeysan karaa ilaa 3000 oo wareeg oo autoclaving ah heerkul ah 134 ° C, taasoo ka dhigaysa mid ku habboon soo saarista qalabka qalliinka iyo ilkaha ee aadka loo nadiifiyey ee u baahan isticmaalka soo noqnoqda. PEEK ma laha oo keliya faa'iidooyinka miisaanka fudud, iska caabbinta aan sunta ahayn iyo daxalka, laakiin sidoo kale waxay leedahay astaamaha modulus-ka dabacsan ee lafaha cortical-ka aadanaha, kaas oo si dabiici ah loogu dari karo jirka. Sidaa darteed, isticmaalka resin PEEK halkii laga isticmaali lahaa birta si loo soo saaro qalfoofka aadanaha waa codsi kale oo muhiim ah oo ku saabsan caafimaadka.

PEEK waxaa markii ugu horreysay loo isticmaalay xarunta caafimaadka sanadkii 1999. Tan iyo markaas, in ka badan shan milyan oo qof ayaa isticmaalay.Badeecadaha PEEKwaxaa lagu beeray aadanaha, taasoo ka dhigaysa heerka dahabka ah ee isku-dhafka laf-dhabarta. Sannadihii ugu dambeeyay, PEEK waxaa lagu ammaanay inay tahay "alaab ku habboon jiilka soo socda ee alaabada caafimaad ee la tallaali karo".

Noocyo noocee ah oo qalabka lagu tallaalo ayaa laga sameeyaa PEEK?
(1) beddelka lafaha, qalabka lafaha ee wejiga maxillofacial
(2) qalliinka laf-dhabarta, isku-darka laf-dhabarta
(3) iyo beddelka lafaha sinta, qalabka lagu tallaalo kala-goysyada
(4) qalabka lafaha: saxanka go'an iyo boolal
(5) beddelka ilkaha CFR - PEEK - oo laga sameeyay qalabka ilkaha lagu dhejiyo, ilkaha beenta ah, iyo haynta xididka
(6) qalliinka wadnaha, bamgareynta wadnaha iyo valfyada

Taariikhda PEEK

Muddada bilowga ah ee ku-meel-gaadhka (1978-1992):

PEEK waa balaastik injineernimo gaar ah oo aad u tayo sare leh oo ay samaysay ICI sanadkii 1978. ICI waxay codsatay shati waxayna warshadaysay, iyadoo leh awood wax soo saar oo ah 1000 tan sannadkii, taas oo inta badan loo isticmaalo warshadaha difaaca.

Horumarinta iyo Burburka Monopoly-ga (1993-2004):

Victrex waxay ganacsiga PEEK ka heshay ICI, taasoo muujinaysa isbeddel horumarineed oo kali ah, waxayna si joogto ah u ballaarisay heerka wax soo saarka. Sannadkii 2003, awoodda wax soo saarka sanadlaha ah waxay kor u kacday 2800 tan. Intaa ka dib, badeecooyin la mid ah ayaa si isdaba joog ah u soo saaray DuPont, BASF, Mitsui Tosei Chemical Company ee Japan, iyo Telep ee Mareykanka. PEEK waxay ka fidday codsiyadeedii milatari ee bilowga ahaa ilaa codsiyada warshadaha iyo kuwa bayoolajiga.

Muddo dheer PEEK waxaa lagu taxay agab istaraatiiji ah oo loogu talagalay xayiraadda iyo cunaqabataynta Shiinaha Guddiga Isku-dubaridka Paris. Si loo daboolo baahiyaha difaaca qaranka iyo horumarinta tiknoolajiyadda sare ee madaniga ah, dawladdu waxay ku dartay mashaariicda cilmi-baarista sayniska iyo tignoolajiyada muhiimka ah ee qaranka laga bilaabo Qorshaha shanaad ee shanta sano ilaa Qorshaha tobnaad ee shanta sano iyo Qorshaha 863 ee cilmi-baarista. Iyada oo taageero xooggan ka haysata siyaasadaha Shiinaha, kooxda Professor Wu Zhongwen ee Jaamacadda Jilin waxay si madax-bannaan u horumariyeen tignoolajiyada patent-ka PEEK oo leh xuquuq madaxbannaan oo hanti-garaafeed waxayna aasaaseen Jida High-tech Materials Co., LTD., kaas oo la geliyay wax soo saar.

Marxaladda Horumarinta Dhammaystiran (2005-hadda):

Sannadkii 2005, Evonik waxay iibsatay ganacsiga The PEEK ee Garda ee Hindiya, halka Solvay ay heshay ganacsiga PEEK. Sannadkii 2009, Shirkadda Jinfa Technology Co., LTD. ee Shiinaha, Panjin Zhongrun Special Plastic Co., Ltd. iyo shirkado kale ayaa soo galay goobta, PEEK-na waxay gashay marxaladda horumarinta oo dhan. Intaa waxaa dheer, wax ka beddelka tignoolajiyada isku-dhafka ah iyo farsamaynta PEEK ayaa si tartiib tartiib ah u koraysa, goobta codsiguna sidoo kale way sii ballaaranaysaa. Sababtoo ah tirada badan ee soosaarayaasha ku takhasusay wax soo saarka PEEK ee adduunka oo dhan, heerka tartanka suuqa ayaa sii kordhaya. Waqtigan xaadirka ah, Wiggs, Solvay iyo Evonik waa saddexda soosaare ee PEEK ee ugu waaweyn adduunka.
