Kev ruaj ntseg tshuaj zoo heev: PEEK muaj kev tiv thaiv zoo rau feem ntau cov tshuaj, nrog rau cov kua qaub, alkalis, cov kuab tshuaj thiab cov xov xwm corrosive.
Cov khoom siv kho tshuab zoo heev: PEEK muaj qhov zoo rigidity, tensile lub zog thiab hnav tsis kam, thiab muaj cov cuab yeej zoo heev.
Tsis tshua muaj kev sib txhuam coefficient: PEEK muaj lub ntsej muag du thiab tsis tshua muaj kev sib txhuam coefficient, uas pab txo qis kev sib txhuam thiab hnav.
Tus qauv tsim: PEEK kev txhawb nqa sealing nplhaib feem ntau muaj ob ntu:
Lub nplhaib sab nraud: Lub nplhaib sab nrauv yog lub nplhaib-zoo li tus qauv ua los ntawm cov khoom siv PEEK, uas muaj kev hnav zoo heev thiab tshuaj tiv thaiv corrosion thiab tuaj yeem tiv thaiv lub nplhaib puab los ntawm kev yaig thiab hnav los ntawm cov xov xwm sab nraud.
Lub nplhaib puab: Lub nplhaib puab yog ib qho qauv tsim los ntawm cov khoom siv elastic (xws li roj hmab), nws txoj haujlwm yog los muab cov nyhuv sealing thiab tswj lub siab.
Daim ntawv thov teb: PEEK kev txhawb nqa sealing rings yog dav siv nyob rau hauv sealing ib puag ncig uas yuav tsum tau kub, siab kub thiab tshuaj corrosion kuj.
Tej daim ntawv thov teb suav nrog
Kev lag luam roj thiab roj: siv rau cov khoom sib khi xws li li qub, twj thiab cov kav dej.
Kev lag luam tshuaj: siv rau hauv cov khoom siv tshuaj, reactors thiab seals, thiab lwm yam.
Aerospace kev lag luam: siv nyob rau hauv aircraft cav, aviation qhov rooj thiab spacecraft, thiab lwm yam.
Qhov zoo thiab nta
Kev kub siab ua haujlwm siab: PEEK kev txhawb nqa lub nplhaib sib khi tuaj yeem tswj tau qhov kev sib khi zoo thiab lub zog txhua yam hauv qhov kub thiab txias.
Tshuaj tiv thaiv corrosion: PEEK cov khoom muaj kev tiv thaiv zoo rau ntau yam tshuaj lom neeg thiab tuaj yeem siv rau hauv qhov chaw corrosive ntev.
Tsis tshua muaj kev sib txhuam thiab hnav: PEEK kev txhawb nqa lub nplhaib muaj qhov zoo ntawm tus kheej lubricating, txo kev sib txhuam thiab hnav thiab txuas ntxiv lub neej kev pab cuam.
Dimensional stability: PEEK muaj kev ruaj ntseg zoo heev thiab tsis yooj yim cuam tshuam los ntawm kev hloov pauv kub thiab kev tshaj tawm, ua kom muaj kev sib khi ruaj khov.
Nws yuav tsum raug sau tseg tias tshwj xeeb PEEK kev txhawb nqa lub nplhaib sib khi cov khoom yuav muaj cov qauv sib txawv thiab cov qauv tshwj xeeb, thiab cov khoom tsim nyog tuaj yeem xaiv raws li kev thov tshwj xeeb.
