Modified polytetrafluoroethylene (PTFE), a high-performance engineering plastic, is widely used in aerospace, automotive, chemical equipment, and electronics. Nws cov coefficient ntawm kev sib txhuam, tshuaj lom neeg zoo heev, thiab ntau cov khoom siv hluav taws xob zoo rau ntau cov chaw xav tau. Txawm li cas los xij, mastering cov txheej txheem tshwj xeeb yog qhov tseem ceeb rau kev ua siab siab -}} zoo hloov PTFE seem.
Cov Khoom Siv Raw Xaiv thiab Cov Lus Qhia Pretrecusic
Xaiv qhov tsim nyog hloov PTFE substrate yog thawj kauj ruam los ua tiav kev tsim qauv. Cov qauv kev hloov kho ib txwm muaj xws li cov iav fiber ntau ntxiv, tooj ua kom tooj, thiab molybdenum cov zog ntxiv, txhua tus uas imparts txawv ntawm cov khoom. Iav cov fiber ntau txhawb kom yooj yim txhim kho txhua yam muaj zog thiab seem ruaj khov; Carbon fiber ntau txhawb ntxiv txhim kho cov coj tsis kam thiab hluav taws xob ua haujlwm; Bronze filling Thermal Condivity; Thiab molybdenum disculide zoo txo cov coeffient ntawm kev sib txhuam.
PTFE cov ntaub ntawv raw yuav tsum tau muab kom huv ua ntej kev ua haujlwm. Txawm hais tias cov PTFE ntshiab muaj tsawg hygroscopicity, ntau cov kev hloov kho ntxiv kev hloov kho tuaj yeem nce nws cov dej nqus. Nws raug pom zoo kom qhuav cov ntaub ntawv raw hauv qhov cub ntawm 120-150℃rau 2-4 teev kom ntseeg tau tias cov dej noo cov ntsiab lus hauv qab 0.02%. Txog kev hygroscopic hloov tsim cov qauv, ntau txoj kev nruj me ntsis kom qhuav. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom kuaj qhov kev sib xyaw thiab cov xim sib xyaw ntawm cov khoom siv raw ua ke thiab cuam tshuam ncaj qha rau kev ua haujlwm sib xws ntawm ntu kawg.
