PEEK yog dab tsi? Thiab cov yam ntxwv ntawm PEEK

Polyetheretherketone (PEEK) yog ib qho semi-crystalline high-temperature thermoplastic uas siv ntau dua hauv cov teb kev lag luam high-tech xws li kev ua haujlwm siab kho mob tubing, aviation, machinery, electronics, tshuaj lom neeg, thiab tsheb vim nws cov biocompatibility, zoo heev lub cev thiab hluav taws xob, tshuaj lom neeg tsis kam, thiab yooj yim sterilize.

PEEK tau siv thawj zaug hauv kev lag luam aerospace, hloov txhuas thiab lwm yam khoom siv hlau hauv kev tsim ntau yam khoom siv dav hlau. Hauv kev lag luam tsheb, PEEK resin muaj kev sib txhuam zoo thiab cov khoom siv kho tshuab. Ua cov khoom siv raw rau kev tsim cov npog sab hauv ntawm lub cav, ntau yam khoom xws li cov kabmob, cov gaskets, cov ntsaws ruaj ruaj, thiab cov nplhaib clutch tau siv dav hauv kev sib kis tsheb, nres, thiab cov tshuab cua txias.

Tshuab PEEK yog ib qho khoom siv hluav taws xob zoo tagnrho. Nws tseem tuaj yeem tswj tau cov khoom siv hluav taws xob zoo nyob rau hauv cov xwm txheej ua haujlwm hnyav xws li kub siab, siab siab thiab av noo siab. Yog li ntawd, thaj chaw cov ntaub ntawv hluav taws xob tau maj mam dhau los ua thaj chaw thov thib ob loj tshaj plaws ntawm Tshuab PEEK, tsim cov kav dej, cov qhov dej thiab cov twj tso kua mis rau kev thauj cov dej ntshiab heev. Hauv kev lag luam semiconductor, nws feem ntau siv los tsim cov wafer carriers, cov diaphragms rwb thaiv tsev hluav taws xob thiab ntau yam khoom siv sib txuas. Ua ib lub yas engineering semi-crystalline, PEEK tsis yaj hauv yuav luag txhua cov kuab tshuaj tshwj tsis yog cov kua qaub sulfuric uas muaj concentrated, yog li nws feem ntau siv los ua cov phaj compressor valve, piston rings, seals thiab ntau yam tshuaj twj tso kua mis lub cev thiab cov khoom siv valve.

Cov yam ntxwv ntawm PEEK yog raws li nram no

1. Tiv taus kub thiab txias heev, ua rau siv tau ntev txog li 260 degrees.

2. Cov khoom siv PEEK tuaj yeem tiv taus kev xeb thiab kev laus.

3. Cov khoom siv PEEK muaj kev tiv taus siab rau kev yaj.

4. Cov khoom siv PEEK muaj cov xwm txheej rau qhov kub thiab txias, zaus siab thiab cov khoom siv hluav taws xob siab.

5. Cov khoom siv PEEK muaj zog thiab ruaj khov.

6. Cov khoom siv PEEK tsis yooj yim hnav thiab muaj cov khoom tiv thaiv xeb zoo.

7. Cov ntaub ntawv raw suav nrog qib implant thiab qib kev cuam tshuam. (nrog rau daim ntawv qhia txog biocompatibility)

PEEK polyetheretherketone kuj tseem tuaj yeem tiv taus txog li 3,000 lub voj voog ntawm autoclaving ntawm 134 ° C. Qhov no tso cai rau nws siv rau hauv kev tsim cov khoom siv phais thiab kho hniav nrog kev xav tau kev tua kab mob siab thiab siv ntau zaus. PEEK polyetheretherketone tsis yog tsuas yog muaj qhov zoo ntawm qhov hnyav sib dua, tsis muaj tshuaj lom, tiv taus corrosion, thiab lwm yam, tab sis nws tseem yog cov khoom siv ze tshaj plaws rau cov pob txha tib neeg thiab tuaj yeem sib xyaw ua ke nrog lub cev tib neeg. Yog li ntawd, siv PEEK polyetheretherketone resin hloov hlau los tsim cov pob txha tib neeg yog lwm daim ntawv thov tseem ceeb hauv kev kho mob. Kev tsim khoom hauv tsev tsim kho sai. PEEK resin tau tsim los ntawm lub tuam txhab Askiv thawj ICI thaum xyoo 1970s. Txij li thaum nws pib, nws tau siv ua cov khoom siv tiv thaiv lub tebchaws tseem ceeb, thiab ntau lub tebchaws tau txwv kev xa khoom tawm.
