FKM High Fluorine (70%)
Fluoroelastomer FKM Terpolymer Gum-246 mndandanda ndi terpolymer wa vinylidenefluoride,tetrafluoroethylene ndi hexafluoropropylene. kwa nthawi yayitali, mu 320 ℃ kwa nthawi yochepa. The katundu wa antil mafuta ndi anti acid ndi bwino kuposa FKM-26, kukana FKM246 kwa mafuta, ozoni, kuwala, magetsi ndi flamer ndi ofanana 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 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 wabwino 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 fluorous ikakumana 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 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, 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.
