Poly-ether-ether-ketone PEEK LCF40 Tsis tshua muaj kev sib txhuam coefficient thawj xim rau High-tech teb

PEEK Khoom siv

Polyether ether ketone (PEEK) yog cov khoom siv hluav taws xob semi-crystalline thermoplastic polymer nrog cov nplhaib benzene nruj, ua raws li ether daim ntawv cog lus thiab cov pab pawg carbonyl uas tuaj yeem txhawb nqa lub zog intermolecular hauv nws cov saw molecular. PEEK muaj kev hnav zoo heev, hluav taws xob rwb thaiv tsev, tiv thaiv hluav taws xob, tshuaj lom neeg ruaj khov, biocompatibility thiab thermal stability. Tsis tas li ntawd, PEEK yog rov siv tau dua thiab muaj tus nqi rov qab siab dua.

Polyether ether ketone (PEEK) yog tib yam ntawm polyether ether ketone (PAEK) cov khoom uas tuaj yeem ua rau loj-tsim tam sim no. PEEK, raws li hom tshwj xeeb engineering yas, muaj cov khoom zoo heev.

PEEK Application

PEEK yog dav siv hauv aerospace, khoom siv hluav taws xob thiab hluav taws xob, biomedicine, Marine kev tiv thaiv, kev lag luam tsheb, thiab lwm yam. PEEK cov khoom yog cov khoom siv tsis muaj zog uas tsis muaj lub zog tsis muaj zog, thiab nws cov khoom siv kho tshuab thiab cov khoom sib txhuam tsis tuaj yeem ua tau raws li qhov xav tau ntawm qee qhov tshwj xeeb.Yog li ntawd, nws yuav tsum tau hloov kho PEEK cov khoom siv los txhim kho nws cov khoom siv dav.

Tam sim no, kev hloov pauv thiab kev sib xyaw ua ke yog txoj hauv kev tseem ceeb rau kev npaj PEEK cov ntaub ntawv sib xyaw. Filler-modified reinforcement cov ntaub ntawv tsuas yog muaj fiber ntau, inorganic hais thiab whiskers; Cov polymer siv rau kev hloov pauv yuav tsum muaj cov polarity zoo sib xws thiab solubility rau PEEK. Txoj kev hloov kho interface tuaj yeem txhim kho qhov kev sib txuas ua ke thiab txhim kho cov khoom zoo ntawm PEEK cov khoom sib xyaw.

Piv txwv li, PEEK sau Long Carbon Fiber (LCF).

Raws li kev ntim khoom, fiber ntau tuaj yeem nqa ib feem ntawm cov khoom thauj, thiab kev sib koom ua ke ntawm fiber ntau thiab PEEK tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov ntaub ntawv sib xyaw. Cov pa roj carbon fiber ntau thiab iav fiber ntau yog siv los ua cov khoom siv hloov pauv vim lawv lub zog siab, siab modulus, thiab ua haujlwm siab. Ntev carbon fiber (LCF) tuaj yeem siv los ua tus neeg sawv cev heterogeneous nucleating los txhawb cov crystallization ntawm PEEK hauv cov ntaub ntawv sib xyaw, uas tuaj yeem txhim kho cov khoom siv dag zog thiab kev sib txhuam ntawm cov khoom sib xyaw.

PEEK yam ntxwv

(1) Machinability: PEEK resin muaj qhov zoo ntawm qhov kub thiab txias fluidity, siab thermal decomposition kub, tuaj yeem siv rau hauv kev txhaj tshuaj molding, extrusion molding, molding, tshuab moulding, yaj spinning, teb molding thiab hmoov txau thiab lwm txoj kev ua.
(2) Kev tiv thaiv hluav taws xob: muaj cov hluav taws xob muaj zog tiv thaiv, nyob rau hauv cov koob tshuaj ntau ntawm cov hluav taws xob cov khoom siv hluav taws xob tseem tuaj yeem ua tiav kev tuav pov hwm, ntau dua li cov khoom siv hluav taws xob hluav taws xob zoo tshaj plaws ntawm polystyrene, tuaj yeem siv los ua cov khoom siv hluav taws xob hauv cov hluav taws xob tiv thaiv.
(3) Nplaim hluav taws xob: PEEK muaj qhov tua tus kheej, txawm tias tsis muaj nplaim taws, mus txog UL tus qauv 94V-0.
(4) Creep resistance: Nyob rau hauv qhov kev txiav txim ntawm qhov kev ntxhov siab tas li, cov khoom yuav tas li deform mus rau hauv creep nyob rau hauv ib lub sij hawm. PEEK yog qhov zoo tshaj plaws creep-tsis kam rau cov khoom siv thermoplastic.
(5) Toughness thiab rigidity: Nws muaj lub zog tensile siab, siab zog tawg lub zog, tshwj xeeb tshaj yog qaug zog tiv thaiv nyob rau hauv alternating kev ntxhov siab yog qhov tseem ceeb, thiab muaj peev xwm muab piv rau cov ntaub ntawv alloy.
(6) Self-lubrication (hnav tsis kam): PEEK muaj cov yam ntxwv zoo heev zawv zawg, haum rau cov kev cai nruj ntawm kev sib txhuam coefficient thiab hnav tsis kam; Tshwj xeeb tshaj yog nrog carbon fiber, graphite, thiab PTFE-hloov PEEK hnav tsis kam yog superior heev.
(7) Kub-kub kuj: PEEK muaj qhov kub hloov pauv iav (Tg=143 degree) thiab melting point (Tm=334 degree ). Nws load thermal deformation kub yog siab li 316 degree, nws siv mus sij hawm ntev kub yog 260 degree, thiab nws instantaneous siv kub tuaj yeem ncav cuag 300 degree. Kev ua haujlwm ntev nyob rau hauv qhov kub thiab txias siab tsis poob ib qho kev ua haujlwm ntawm lub cev.
(8) Hydrolytic tsis kam: PEEK cov khoom tuaj yeem ua haujlwm tsis tu ncua rau ntau txhiab teev yam tsis muaj kev ua haujlwm tseem ceeb hauv chav dej ntawm 260 degree lossis raus hauv dej siab; Ntawm tag nrho cov engineering plastics, PEEK muaj qhov zoo tshaj plaws tiv thaiv hydrolysis thiab chav.
(9) Tsis muaj tshuaj lom: tuaj yeem siv rau hauv kev noj zaub mov huv, khoom siv kho mob thiab lwm yam haujlwm.
(10) Corrosion kuj: Tsuas yog cov concentrated sulfuric acid, PEEK yog insoluble nyob rau hauv tej yam hnyav, muaj zog acid, muaj zog puag, thiab muaj tshuaj stability.
(11) Fatigue resistance: PEEK muaj qhov zoo tshaj plaws qaug zog tiv thaiv ntawm tag nrho cov thermoplastic resin cov ntaub ntawv.
