FKM High Fluorine (70%)
Fluoroelastomer FKM Terpolymer Gum-246 mndandanda ndi terpolymer wa vinylidenefluoride,tetrafluoroethylene ndi hexafluoropropylene. kwa nthawi yayitali, mu 320 ℃ kwakanthawi kochepa.Katundu wa mafuta oletsa antil ndi anti acid ndiabwino kuposa FKM-26,kukana FKM246 kumafuta, ozoni, radiation,magetsi ndi flamer ndizofanana ndi FKM26.

Kugwiritsa Ntchito Mankhwala
FKM246 chimagwiritsidwa ntchito magalimoto, makina, petrochemical, ndi zina fields.For Mwachitsanzo, ndege malo amodzi / zazikulu zisindikizo zipangizo hayidiroliki dongosolo ndi kondomu dongosolo; ntchito pobowola zida ndi mapaipi mafuta; makampani mankhwala kwa zida, flexible chitoliro kugwirizana, liner wa mpope kapena dzimbiri zosagwira kusindikiza zakuthupi, zopangidwa ndi mapaipi kunyamula zosungunulira kapena zinthu zina, monga dzimbiri.
Chidwi
1.Fluoroelastomer terpolymer mphira ali bwino kutentha bata pansi 200 ℃.It adzapanga kufufuza kuwonongeka ngati kuika pa 200-300'C kwa nthawi yaitali, ndipo kuwonongeka kwake liwiro Imathandizira pa pamwamba 320 ℃, mankhwala kuwola makamaka poizoni wa hydrogen fluoride. ndi fluorocarbon organic compound.Pamene mphira yaiwisi ya fulorosi ikumana ndi moto, imatulutsa poizoni wa hydrogen fluoride ndi fluorocarbon organic pawiri.
2.FKM sichingasakanizidwe ndi ufa wachitsulo monga aluminium ufa ndi magnesium powder, kapena over10% amine compound, ngati izo zichitika, kutentha kudzawuka ndipo zinthu zingapo zidzachita ndi FKM, zomwe zidzawononga zipangizo ndi ogwira ntchito.
Phukusi, Mayendedwe ndi Kusungirako
1.FKM imadzaza m'matumba apulasitiki a PE, kenaka imakwezedwa m'makatoni, kulemera kwa katoni iliyonse ndi 20kg.
2.FKM imasungidwa m'nyumba yosungiramo zinthu zoyera, zowuma komanso zoziziritsa. Zimatengedwa molingana ndi mankhwala omwe si owopsa, ndipo ziyenera kukhala kutali ndi gwero loipitsidwa, kuwala kwa dzuwa ndi madzi panthawi yoyenda.
