Polytetrafluoroethylene (PTFE), hu ua "Huab Tais" rau nws cov khoom siv lub cev ruaj khov thiab siv tau dav hauv kev lag luam, kev kho mob, thiab aerospace kev lag luam. Txij li thaum nws txoj kev txhim kho los ntawm dupont nyob rau xyoo 1946, PTFE tau dhau los ua cov khoom tseem ceeb hauv kev lag luam niaj hnub vim nws cov khoom tshwj xeeb.
Tshuaj lom neeg inertness thiab corrosion tsis kam yog ntawm ptfe qhov tseem ceeb tshaj plaws. Nws yog kev tsis txaus siab nrog txhua yam tshuaj lom neeg, suav nrog cov muaj zog acids, hauv paus, thiab cov kuab tshuaj organic. Therefore, it is commonly used in chemical reactors, pipe linings, and seals, ensuring long-term stable operation in extremely corrosive environments.
PTFE's Ultra - tsis muaj kev sib txhuam ua rau nws lub roj nplua nyeem zoo tshaj plaws. Nws cov txheej txheem saum npoo sib txhuam tsuas yog kwv yees li 0.04, txawm qis dua li ntawm cov dej khov. Nws yog dav siv nyob rau hauv bearings, ntsaws ruaj ruaj, thiab tsis - cov nqaij nyuj (xws li teflon). Cov xeeb ceem no tsis tsuas yog txo kev hnav mechanical, tab sis kuj qis dua hluav taws xob siv thiab ua rau muaj cov khoom siv lub neej.
PTFE tseem kawm tau zoo nyob rau hauv high - kub} kev ua tau zoo thiab rwb thaiv tsev. Nws tswj hwm kev ruaj khov tshaj qhov kub ntawm -200 Qib rau ntawm 260 degree, ua rau muaj cov khoom siv hluav taws xob ntau rau cov xov hlau, cov xaim hluav taws xob, thiab ntim hluav taws xob ntxiv.
PTFE tsis yog - Cov Khoom Siv Hluav Taws Xob, thiab UV Cov Khoom Kho Mob Ua Haujlwm xws li cov hlab ntsha tsis zoo xws li cov hlab ntshav ntawm lub plawv dhia. Nws tseem ua lub luag haujlwm tseem ceeb hauv kev tsim kho (xws li waterproof thiab breathable membranes) thiab khoom siv sab nraum zoov.
Nrog kev txhim kho thev naus laus zis, kev tshawb fawb ntawm PTFE kev hloov pauv tseem ua kom tiav, muaj cov iav fiber ntau, txuas ntxiv nthuav nws cov ntawv thov. Nyob rau hauv lub neej yav tom ntej, "huab tais ntawm plastics" tseem yuav qhia tau nws tus nqi tsis zoo thiab muaj kev tsim khoom lag luam thiab tawm.
