FKM (Copolymer) fluoroelastomer Gum-26
FKM copolymer Gum-26 mndandanda ndi copolymer wa vinylidenefluoride ndi hexafluoropropylene, amene fluorine zili kupitirira 66%. Pambuyo valcanizing ndondomeko, mankhwala ndi ntchito makina abwino kwambiri, katundu anti mafuta mafuta (mafuta opangira, mafuta opangira mafuta) ndi kukana kutentha, zomwe zingagwiritsidwe ntchito m'mafakitale a magalimoto
Muyezo woyeserera: Q/0321DYS005

Kugwiritsa Ntchito Mankhwala
Amagwiritsidwa ntchito kwambiri popanga ma washers, ma gaskets, mphete za O, mphete za V, zisindikizo zamafuta, ma diaphragms, mapaipi amphira, zotchingira chingwe, nsalu zotchinjiriza kutentha, mbale za valve, zolumikizira zowonjezera, masikono a rabara, zokutira ndi kutentha kwa chipinda cham'chipinda chokanira kutentha kwambiri, mafuta (mafuta agalimoto), mafuta opaka (mafuta opangira), madzi (zosungunulira zosiyanasiyana zosakhala polala). dzimbiri (acid, alkali), oxidizer wamphamvu (oleum), ozoni, radiation ndi nyengo.
Chidwi
1. FKM ili ndi kukhazikika kwa kutentha kwabwino pansi pa 200 ℃. Idzatulutsa kuwonongeka ngati ikuyikidwa pa 200-300 ℃ kwa nthawi yaitali, ndipo kuthamanga kwake kumawola kumathamanga pamwamba pa 320 ℃, zinthu zowonongeka zimakhala ndi poizoni wa hydrogen fluoride ndi fluorocarbon organic. Pakakhala mphira yaiwisi ya fluorous itakumana ndi moto, imatulutsa poizoni wa hydrogen fluoride ndi fluorocarbon orgainc pawiri.
2. FKM sichingasakanizidwe ndi ufa wachitsulo monga aluminium ufa ndi magnesium ufa, kapena kupitirira 10% amine pawiri, ngati izo zitachitika, 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, 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.
