PEEK yog dab tsi

PEEK YOG DAB TSI?

Polyether ether ketone (PEEK) yog xim tsis muaj cov organic thermoplastic polymer hauv tsev neeg polyaryletherketone (PAEK), siv rau hauv kev siv engineering.

PEEK yog cov semicrystalline thermoplastic nrog cov cuab yeej zoo nkauj thiab tshuaj lom neeg uas muaj kev tiv thaiv zoo kom muab khaws cia kom sov siab. Cov txheej txheem ua haujlwm siv los pwm PEEK tuaj yeem cuam tshuam cov muaju, thiab vim li no cov khoom siv kho tshuab. Tus Hluas' s modulus yog 3.6 GPa thiab nws lub zog tensile 90 rau 100 MPa. PEEK muaj kev hloov pauv kub iav ntawm ib puag ncig 143 ° C (289 ° F) thiab yaj tag li 343 ° C (662 ° F). Qee qib muaj qhov ntsuas kub tau siv tau txog li 250 ° C (482 ° F). Nws tiv taus zoo rau thermal degradation zoo li muaj kev tawm tsam los ntawm ob qho tib si organic thiab aqueous ib puag ncig. Nws tau tawm tsam los ntawm halogens thiab muaj zog acids zoo li qee qhov sib xyaw halogenated thiab aliphatic hydrocarbons ntawm qhov kub siab. Nws yaj tag nrho nyob rau hauv cov concentrated sulfuric acid ntawm chav tsev kub.

Vim tias nws qhov ua tau zoo, PEEK yog siv los ua cov khoom siv hauv cov ntawv thov, nrog rau cov kabmob, qhov chaw ntawm lub twj tso kua mis, lub twj tso kua mis, HPLC cov ntawv, compressor phaj li qub, thiab cable rwb thaiv tsev. Nws yog ib qho ntawm ob peb plastics txuam nrog ultra-siab nqus plua plav thov. Nws yog dav siv hauv kev lag luam aerospace, tsheb, thiab kev lag luam chemical.
