PEEK cov khoom siv nrog kev ua haujlwm siab engineering yas hauv kev ua haujlwm kub zoo, tshuaj lom neeg tsis kam, txhua yam muaj zog thiab qhov ruaj khov
PEEK cov ntaub ntawv yog cov khoom siv ua haujlwm siab ua haujlwm nrog cov khoom siv hluav taws xob zoo heev, tshuaj lom neeg ua haujlwm, lub zog txhua yam thiab qhov ruaj khov.
Yam ntxwv Thiab Daim Ntawv Thov Cheeb Tsam Ntawm Peek Khoom
1. High kub teb: PEEK cov khoom ua tau zoo nyob rau hauv qhov kub thiab txias thiab tuaj yeem tiv taus qhov kub txog li 300 ° C. Yog li ntawd, nws yog dav siv nyob rau hauv aerospace, automotive, tshuaj, zog thiab lwm yam kev lag luam ntawm kub kub qhov chaw tsim khoom.
2. Tshuaj tiv thaiv corrosion: PEEK cov khoom muaj cov tshuaj tiv thaiv corrosion zoo thiab tuaj yeem ua haujlwm ruaj khov hauv ntau hom tshuaj lom neeg xws li acids, alkalis thiab organic solvents. Yog li ntawd, nws yog siv dav hauv kev tsim cov khoom siv tshuaj, cov kav dej, li qub thiab lwm yam khoom siv.
3. Kev kho mob teb: PEEK cov khoom muaj cov yam ntxwv ntawm biocompatibility thiab tsis muaj tshuaj lom, yog li nws tau siv dav hauv kev tsim cov khoom siv kho mob thiab cov khoom siv dag zog. Piv txwv li, vascular stents, pob qij txha tsim, tracheal intubation thiab lwm yam khoom ua los ntawm cov ntaub ntawv PEEK tau siv dav hauv kev kho mob.
4. Electronic field: PEEK cov khoom muaj cov khoom siv hluav taws xob zoo heev thiab cov khoom siv dag zog, yog li nws tau siv dav hauv kev tsim khoom siv hluav taws xob. Piv txwv li, cable bushings, connectors, sockets thiab lwm yam khoom uas ua los ntawm PEEK cov ntaub ntawv tau lug siv nyob rau hauv lub hwj chim, kev sib txuas lus, computers teb.
5. Automotive kev lag luam: PEEK cov ntaub ntawv muaj cov cua kub zoo thiab lub zog txhua yam, kuj muaj kev sib txhuam zoo thiab cov tshuaj tiv thaiv corrosion. Yog li ntawd, nws yog dav siv nyob rau hauv kev tsim cov tsheb cav qhov chaw, kis tau tus mob qhov chaw, nres system qhov chaw.
PEEK cov ntaub ntawv muaj ntau yam kev siv thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev lag luam thiab kev lag luam sib txawv. Los ntawm kev xaiv cov khoom tsim nyog thiab kev siv thev naus laus zis, cov khoom lag luam zoo thiab kev ua haujlwm siab PEEK tuaj yeem tsim
