PERFLUOROELASTOMERS
Ma Perfluoroelastomers (FFKM) amapangidwa makamaka kuchokera ku tetrafluoroethylene, perfluoromethyl vinyl ether, ndi vulcanization point monomers, ndipo amakana kwambiri ndi mankhwala, kutentha, extrusion, komanso kutentha kwambiri.Kupatula zosungunulira zina zapamwamba za fluorocarbon, sizimakhudzidwa ndi sing'anga iliyonse, kuphatikiza ma ether, ma ketoni, esters, amides, nitriles, oxidizing agents, mafuta, zidulo, alkali, ndi zina zambiri. katundu.

Ntchito zazikulu
1.This mankhwala ndi triazine vulcanized perfluoroelastomer, ntchito pa kutentha kuyambira 275 ℃ mpaka 300 ℃.Itha kugwiritsidwa ntchito kwakanthawi kochepa kutentha kwambiri mpaka 315 ℃.Perfluoroelastomers amagwiritsidwa ntchito ngati chisindikizo cha mphira ndi mankhwala omwe amalimbana ndi kutentha kwakukulu.strong media corrosive media, ndi zosungunulira zambiri, monga ma diaphragms, mphete zosindikizira, mphete zosindikizira zooneka ngati V, mphete za O, mapaketi, mipira yolimba, gaskets, sheaths, makapu, mapaipi, ndi mavavu.
2.Mainly ntchito ndege, zamlengalenga, makampani mankhwala, petroleum.atomic mphamvu, semiconductor ndi felds ena.
Kugwiritsa ntchito
1. Pamene perfluoroelastomers yaiwisi yakumana ndi moto, imatulutsa poizoni wa hydrogen fluoride ndi fluorocarbon organic compound.
2.Perfluoroelastomers sizingasakanizidwe ndi ufa wachitsulo monga aluminiyamu ndi magnesium powder, kapena pa 10% amine compound, ngati izo zichitika, kutentha kudzauka ndipo zinthu zingapo zidzachitapo ndi perfluoroelastomers, zomwe zidzawononga zipangizo ndi ogwira ntchito.
Phukusi, Mayendedwe ndi Kusungirako
1.Perfluoroelastomers amapakidwa m'matumba apulasitiki a PE ndiyeno amadzaza makatoni.Kulemera kwa Net ndi 20Kg pa bokosi.
2.Perfluoroelastomers amatengedwa malinga ndi mankhwala omwe si owopsa.3.Perfluoroelastomers amasungidwa m'nyumba yosungiramo zinthu zouma, zowuma komanso zoziziritsa kukhosi, ndipo amayenera kukhala kutali ndi gwero loipitsidwa, kuwala kwa dzuwa ndi madzi panthawi yamayendedwe.
