Fluoroelastomer tuaj yeem muab faib ua cov hauv qab no.
A. Kho qhov system
B. Monomers
C. Cov ntawv thov
Rau kev kho qhov system, muaj ob txoj hauv kev: Bisphenol curablefkm uathiab peroxide curable fkm. Bishpenol curable fkm feem ntau muaj cov yam ntxwv ntawm cov txheej txheem qis, uas yog siv rau molding sealing qhov chaw xws li orings, gaskets, rings tsis tu ncua, profiles. Thiab Peroxide curable fkm muaj cov tshuaj tiv thaiv zoo dua thiab cov khoom siv kho tshuab. Nws muaj kev tiv thaiv zoo rau chav. Nws tuaj yeem siv rau hauv cov khoom siv ntse ntse lossis lithium roj teeb.
Rau cov monomers, muaj copolymer uas yog tsim los ntawm Vinylidene fluoride (VDF) thiab hexafluoropropylene (HFP); thiab terpolymer uas yog tsim los ntawm Vinylidene fluoride (VDF), tetrafluoroethylene (TFE) thiab hexafluoropropylene (HFP). FKM copolymer muaj 66% fluorine cov ntsiab lus tuaj yeem siv rau hauv daim ntawv thov dav dav. Thaum fkm terpolymer muaj fluorine cov ntsiab lus txog 68%, nws tuaj yeem siv rau hauv ib puag ncig hnyav uas yuav tsum muaj tshuaj lom neeg zoo dua / tawm tsam.
Rau cov ntawv thov, FUDI muab molding, calendaring, extrusion qib fkm. Thiab peb kuj muab cov qib tshwj xeeb xws li tsis tshua muaj kub tsis kam qib GLT, cov ntsiab lus fluorine siab nrog cov ntsiab lus fluorine 70%, chav thiab alkali tsis kam qib FEPM Aflas, zoo heev tshuaj tiv thaiv qib perfluoroelastomer ffkm.
