FKM (Terpolymer) fluoroelastomer Gum-246
Fluoroelastomer FKM Terpolymer Gum-246 mndandanda ndi terpolymer wa vinylidenefluoride, tetrafluoroethylene ndi hexafluoropropylene. kwa nthawi yayitali, mu 320 ℃ kwa nthawi yochepa.Katundu wa mafuta oletsa antil ndi anti acid ndi abwino kuposa FKM-26, kukana kwa FKM246 ku mafuta, ozoni, ma radiation, magetsi ndi flamer ndi ofanana ndi FKM26.

Kugwiritsa Ntchito Mankhwala
FKM246 chimagwiritsidwa ntchito magalimoto, makina, petrochemical, ndi zina fields.Mwachitsanzo, zazikulu zisindikizo zipangizo za hayidiroliki dongosolo ndi lubrication dongosolo; ntchito pobowola zida ndi mapaipi mafuta; makampani mankhwala zida, flexible chitoliro kugwirizana, liner wa mpope kapena zotchinga zosagwira dzimbiri, zopangidwa ndi mapaipi onyamula zosungunulira kapena zinthu zina, monga dzimbiri.
Chidwi
1.Fluoroelastomer terpolymer mphira ali wabwino kutentha bata pansi 200 ℃.Idzapanga kufufuza kuwonongeka ngati kuika pa 200-300'C kwa nthawi yaitali, ndi kuwola liwiro Imathandizira pa pamwamba 320 ℃, mankhwala kuwola makamaka poizoni hydrogen fluoride. ndi fluorocarbon organic compound.Pamene mphira yaiwisi ya fluorous ikakumana ndi moto, imatulutsa poizoni wa haidrojeni fluoride ndi fluorocarbon organic pawiri.
2.FKM sichingasakanizidwe ndi ufa wachitsulo monga aluminium ufa ndi magnesium powder, kapena over10% amine compound, ngati izi zichitika, kutentha kudzauka ndipo zinthu zingapo zidzagwira ntchito ndi FKM, zomwe zidzawononga zipangizo ndi ogwira ntchito.
Phukusi, Mayendedwe ndi Kusungirako
1.FKM imadzaza m'matumba apulasitiki a PE, kenako imayikidwa m'makatoni, kulemera kwa katoni iliyonse ndi 20kg.
2.FKM imasungidwa m'nyumba yosungiramo zinthu zoyera, zowuma komanso zoziziritsa kukhosi. Zimatengedwa molingana ndi mankhwala omwe si owopsa, ndipo ziyenera kukhala kutali ndi gwero la kuipitsidwa, kuwala kwa dzuwa ndi madzi panthawi yoyendetsa.
