Kev taw qhia thiab kev siv Fluroelastomers
fluorine roj hmab hais txog cov hluavtaws polymer elastomer uas muaj fluorine atoms ntawm cov pa roj carbon atoms ntawm cov saw tseem ceeb lossis cov saw hlau sab. Nws tsis tsuas yog muaj cov khoom zoo txhua yam, tab sis kuj muaj kev tiv thaiv siab rau qhov kub thiab txias, roj thiab ntau yam tshuaj. Nws cov yam ntxwv thiab kev ua tau zoo yog qhov tshwj xeeb zoo heev, yog li nws muaj ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom tshwj xeeb sealing. Nws yog qhov tseem ceeb hauv kev siv dav hlau niaj hnub no, missiles, foob pob hluav taws, aerospace thiab lwm yam kev tshawb fawb thiab thev naus laus zis thiab lwm yam kev lag luam (xws li tsheb) Cov khoom siv.

| Lus Teb Ntxiv | |||
| Qhov no yog ib tsev neeg ntawm cov roj hmab tsim los rau kev ua haujlwm kub heev. Lawv tuaj yeem ua haujlwm tsis tu ncua me ntsis dhau ntawm 200 degree nyob ntawm qib, thiab sib cuam tshuam mus rau qhov kub thiab txias li 300 degree. Lawv muaj kev tiv thaiv zoo rau tshuaj tua kab mob los ntawm oxidation, acids thiab fuels. Lawv muaj roj zoo. Txawm li cas los xij, ntawm qhov kub ua haujlwm siab lawv tsis muaj zog, yog li txhua tus qauv tsim yuav tsum muaj kev txhawb nqa txaus los tiv thaiv kev siv zog. Lawv muaj qhov txwv tsis pub ua haujlwm rau chav dej, dej kub, methanol, thiab lwm yam dej ntau heev. Lawv raug tawm tsam los ntawm amines, muaj zog alkalis thiab ntau freons. Muaj cov qauv thiab cov qib tshwj xeeb thiab cov tom kawg tuaj yeem tsim kom muaj cov khoom tshwj xeeb xws li kev txhim kho qhov kub thiab txias. | |||
