Fpm Khoom Siv Tshuaj Ruaj Ruaj

FPM muaj kev tiv thaiv zoo permeability thiab compression. Nws tsis xeb thaum raug UV lub teeb, ozone, acids, thiab diesel. Thaum siv cov khoom no, cov txheej txheem ntawm kev laus ntawm lub ntshiv yog qeeb ib yam nkaus. Lawv yog cov tsis tshua muaj qhov hloov pauv hauv qhov kub kub thiab qhov ntsuas kub ncua. Vim tias cov khoom zoo li no, FPM cov ntsaws ruaj ruaj yog siv dav hauv cov ntawv thov tsheb, tshwj xeeb tshaj yog hauv cov khoom siv roj thiab cov kev siv cuam tshuam.

Kev nug

Txhawb tshuaj

Fluorocarbon yog elastomers raws li fluororubber (FPM, FKM), tseem hu ua VITON (sau npe kev lag luam ntawm Du Pont), uas tuaj yeem siv rau U-khob, daim di ncauj ntim, ntim khoom, cov ntawv so thiab tshwj xeeb ntim. Nws cov khoom tshwj xeeb suav nrog kev ua haujlwm siab rau cov cua kub, huab cua, ntau yam tshuaj lom neeg thiab nws yog txhua yam huab cua-pov thawj. FPM yog sib xws nrog cov roj ntxhia thiab cov roj nplua nyeem uas muaj cov leej faj, HFD lub siab ua kua (yuav luag txhua txhua phosphate esters thiab chlorinated hydrocarbons), cov roj av thiab cov kua roj. FPM tsis tiv taus kev ua kom tsis muaj zog ammonia, amines, ketones, esters, dej kub thiab tsis tshua muaj molecular hnyav organic acids.

Fluorocarbon ua ke ua hauj kub zoo nrog cov tshuaj tiv thaiv zoo heev. Zoo heev rau siv nrog cawv thiab cov roj ntxhiab roj thiab muaj kev tiv thaiv tiv thaiv ultraviolet teeb thiab ozone. Cov khoom siv no tsis pom zoo siv rau hauv qhov kub qis lossis hauv roj cua tshuab hydraulic. Qhov kub thiab txias ntau yam yog-20Â ° txog +400Â ° F.
