Kub Siab, Tiv Thaiv Kev Sib Tsoo, Siab Precision PEEK Gears
Kev piav qhia txog khoom
Peb cov iav PEEK yog tsim los ntawm kev siv cov thev naus laus zis niaj hnub kom ntseeg tau tias muaj kev ua haujlwm raug thiab zoo ib yam. Kev sib xyaw ua ke ntawm cov khoom siv PEEK thiab cov txheej txheem tsim khoom siab heev ua rau cov iav nrog kev tiv thaiv zoo heev, cov coefficient qis ntawm kev sib txhuam thiab qhov sib piv ntawm lub zog rau qhov hnyav. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas kev ntseeg tau thiab lub neej ntev yog qhov tseem ceeb, xws li cov kab ke xa khoom siab, cov tshuab precision thiab cov khoom siv hnyav.
Cov Khoom Zoo
Cov iav PEEK tau tsim los ua kom zoo dua cov khoom siv iav ib txwm muaj, suav nrog cov hlau thiab lwm yam yas, hais txog kev tiv taus kev hnav, kev txuag qhov hnyav thiab kev ua tau zoo tag nrho. Nws cov khoom siv kho tshuab zoo tshaj plaws tso cai rau nws kom tiv taus qhov kub thiab txias heev, cov tshuaj lom neeg corrosive thiab cov khoom thauj siab yam tsis muaj kev puas tsuaj, ua rau nws zoo tagnrho rau cov ntawv thov tseem ceeb uas tsis zam kev ua tsis tiav. Peb cov iav PEEK muaj peev xwm ua haujlwm hauv qhov chaw nyuaj, muab kev ntseeg siab thiab kev ruaj khov tsis muaj qhov sib piv, txo cov neeg siv khoom lub sijhawm tsis ua haujlwm thiab cov nqi txij nkawm.
Ntxiv rau qhov ua tau zoo tshaj plaws thiab ruaj khov, peb cov iav PEEK yooj yim rau kev teeb tsa thiab tswj. Nws cov khoom sib dua thiab tiv taus xeb ua rau nws yooj yim dua rau kev tuav thiab teeb tsa, txo cov nqi zog ua haujlwm thiab lub sijhawm. Tsis tas li ntawd, nws cov khoom siv nws tus kheej pab txo cov kev xav tau kev saib xyuas, txo cov nqi khiav lag luam ntawm cov neeg siv khoom.

Cov Ntawv Thov Khoom
PEEK qhov kub siv mus sij hawm ntev yog li 260-280 ℃, qhov kub siv luv luv tuaj yeem ncav cuag 330 ℃, thiab qhov siab tiv taus txog li 30MPa, yog cov khoom siv zoo rau cov foob kub siab.
PEEK kuj muaj cov khoom zoo rau nws tus kheej, yooj yim ua, ruaj khov rwb thaiv tsev, tsis kam hydrolysis thiab lwm yam khoom zoo heev, ua rau nws muaj ntau yam kev siv hauv kev lag luam aerospace, kev tsim tsheb, hluav taws xob thiab hluav taws xob, kev kho mob thiab kev ua zaub mov thiab lwm yam teb.
