Polytetrafluoroethylene ntawv, tseem hu ua PTFE ntawv, yog cov khoom siv polymer nrog kev ua tau zoo thiab kev siv dav. Nws daim ntawv thov zoo yog raws li nram no:
1. Corrosion kuj: Polytetrafluoroethylene daim ntawv muaj corrosion kuj zoo heev thiab zoo kuj rau feem ntau cov tshuaj. Nws tuaj yeem siv rau hauv ntau hom acids, alkalis thiab cov kuab tshuaj tsis muaj corrosion thiab puas.
2. Kev kub siab ua haujlwm: PTFE ntawv tuaj yeem ua haujlwm ntawm qhov kub thiab txias, thiab nws qhov kub thiab txias tuaj yeem ncav cuag -200 degree rau +260 degree . Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau ntau yam kev siv hauv qhov kub thiab txias.
3. Non-stickiness: Polytetrafluoroethylene daim ntawv muaj lub zog qis heev, ua rau nws muaj kev sib txhuam coefficient tsawg heev. Qhov no txhais tau hais tias nws muaj cov khoom zoo heev uas tsis yog-stickiness thiab nws tus kheej-lubricating zog, uas tuaj yeem txo qhov adhesion ntawm cov khoom nto, muab nws daim ntawv thov tshwj xeeb zoo hauv ntau qhov chaw.
4. Hluav taws xob rwb thaiv tsev: PTFE ntawv yog cov khoom siv hluav taws xob zoo nrog cov khoom zoo dielectric. Nws tuaj yeem ua haujlwm ntawm high voltage thiab high zaus, thiab tsis nquag arcing, yog li nws yog dav siv hauv electronics, hluav taws xob thiab kev sib txuas lus.
5. Cov khoom siv kho tshuab: PTFE daim ntawv muaj cov khoom siv zoo heev xws li lub zog siab, hardness thiab rigidity. Nws muaj lub zog tensile zoo thiab hnav tsis kam thiab tuaj yeem siv tau ntev hauv ntau qhov chaw hnyav.
6. Kev nyab xeeb ntawm qib zaub mov: PTFE daim ntawv yog cov khoom tsis muaj tshuaj lom thiab muaj ntxhiab tsw uas ua tau raws li cov qauv kev nyab xeeb ntawm qib zaub mov. Yog li ntawd, nws yog dav siv nyob rau hauv kev ua zaub mov thiab kev lag luam, xws li cov thawv ntim khoom noj, cov tais ci thiab cov khoom ci.
Nyob rau hauv luv luv, PTFE daim ntawv muaj qhov zoo ntawm corrosion kuj, kub tsis kam, tsis-stickiness, hluav taws xob rwb thaiv tsev, mechanical zog thiab zaub mov qib kev nyab xeeb, uas ua rau nws lug siv nyob rau hauv tshuaj, hluav taws xob, khoom noj khoom haus, huv si thiab manufacturing teb.
