Tam sim no, PEEK resin kuj tau siv los tsim kev sib xyaw ua ke
Kev kho mob
Hauv kev kho mob, ntxiv rau cov khoom siv phais thiab kho hniav uas yuav tsum tau ua kom tsis muaj menyuam thiab siv ntau zaus, thiab kev tsim kho ntawm qee cov cuab yeej kho mob, qhov tseem ceeb tshaj plaws ntawm kev siv PEEK resin yog cov pob txha pob txha uas tuaj yeem hloov cov hlau siv. Cov pob txha dag ua los ntawm PEEK resin tsis tsuas yog muaj qhov zoo ntawm lub teeb yuag, tsis muaj tshuaj lom thiab muaj zog corrosion kuj, tab sis kuj yog cov khoom siv ze tshaj plaws rau tib neeg cov pob txha hauv yas, uas tuaj yeem txuas nrog lub cev organically. Yog li ntawd, siv PEEK resin es tsis txhob siv hlau ua rau tib neeg cov pob txha yog ib qho tseem ceeb siv hauv kev kho mob, uas muaj qhov tseem ceeb thiab muaj txiaj ntsig.
Kev lag luam tshuab
Hauv kev lag luam kev lag luam, PEEK resin feem ntau yog siv los tsim kom nruj lub tshuab valve daim hlau, piston rings, seals thiab ntau yam tshuaj twj tso kua mis lub cev thiab valve Cheebtsam. Lub impeller ntawm swirl twj tso kua mis yog tsim nrog cov resin no tsis yog stainless hlau. Tsis tas li ntawd, PEEK resin ua tau raws li cov lus qhia tshwj xeeb ntawm cov yeeb nkab ua haujlwm cov ntaub ntawv, thiab txhua yam ntawm cov nplaum tseem tuaj yeem siv rau kev sib txuas ntawm qhov kub thiab txias, yog li cov khoom siv niaj hnub no yuav yog lwm lub lag luam muaj peev xwm.
Tsheb
PEEK cov ntaub ntawv polymeric tuaj yeem ua tiav cov hlau, cov khoom siv sib xyaw ua ke thiab lwm yam yas vim tias lawv muaj zog heev, tshuaj lom neeg inertia thiab nplaim hluav taws kub, thiab yooj yim rau kev ua tiav rau hauv cov khoom me me heev.
