PTFE Lined Flexible Rubber Expansion Joint
Kev piav qhia
PTFE lined roj hmab expansion pob qij txha muaj cov yam ntxwv ntawm kev co txo, tiv thaiv corrosion, acid thiab alkali tsis kam, kub tsis kam, saj zawg zog thiab rub tsis kam, feem ntau yog siv rau pipeline displacement, dimension hloov thiab vibration ib feem kev twb kev txuas, nws yuav siv tau raws li cov khoom thiab cov kua. pipeline rau phiab, chemical engineering, corrosion, vulcanization tank tsheb khoom, thiab lwm yam tshwj xeeb siv.
PTFE luv luv rau Polytetrafluoroethylene, tseem hu ua Teflon, 4F.PTFE muaj tshuaj lom neeg ruaj khov thiab corrosion kuj, nws yog ib qho zoo tshaj plaws corrosion kuj khoom nyob rau hauv lub ntiaj teb no, tshwj tsis yog nws yog xim hlau sodium thiab kua fluorine, PTFE yog tsis kam mus rau tag nrho cov tshuaj, lug siv nyob rau hauv tag nrho cov corrosive ib puag ncig.Tsis tas li ntawd, nws muaj cov khoom sib khi zoo, cov cuab yeej lubricating siab, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob zoo, kev laus tsis kam, kub tsis kam (tuaj yeem ua haujlwm ntev ntawm -180 ℃ txog 250 ℃).
Khoom nta ntawm PTFE lined roj hmab expansion pob qij txha:
Kev kub siab ua haujlwm: ua haujlwm kub txog li 250 ℃.
Tsis tshua muaj kub tsis kam: muaj kev siv tshuab zoo heev, txawm tias qhov kub thiab txias poob mus rau -196 ℃, nws tuaj yeem tuav tau 5% elongation.
Corrosion kuj: tsis kam mus rau feem ntau cov tshuaj.
