PERFLUOROELASTOMERS
Ama-Perfluoroelastomers (FFKM) ahlanganiswa ikakhulukazi kusuka ku-tetrafluoroethylene, perfluoromethyl vinyl ether, kanye nama-monomers we-vulcanization point, futhi anokumelana okuhle kakhulu namakhemikhali, ukushisa, ukukhushulwa, kanye nokuwohloka kokucindezelwa kwezinga lokushisa eliphezulu.Ngaphandle kwezinyibilikisi ezithile eziphakeme ze-fluorocarbon, azithintwa yinoma iyiphi indlela, okuhlanganisa ama-ether, ama-ketone, ama-ester, ama-amides, ama-nitriles, ama-oxidizing aqinile, amafutha okubasa, ama-asidi, ama-alkali, njll. Inokungena okuphansi kumakhemikhali namagesi, nogesi omuhle. izakhiwo.
Izinkomba Zobuchwepheshe

Izinhlelo zokusebenza eziyinhloko
1.Lo mkhiqizo uyi-triazine vulcanized perfluoroelastomer, esetshenziswa emazingeni okushisa asukela ku-275℃ kuya ku-300℃.Ingasetshenziswa isikhathi esifushane emazingeni okushisa afinyelela ku-315 ℃.Ama-Perfluoroelastomers asetshenziswa njengophawu lwenjoloba kanye nomkhiqizo omelana nokushisa okuphezulu.imithombo yezindaba egqwalayo eqinile, kanye nezincibilikisi eziningi, njengama-diaphragm, izindandatho zokuvala, izindandatho zokuvala ezimise okwe-V, izindandatho ze-O, izipaki, amabhola aqinile, ama-gaskets, ama-sheaths, izinkomishi, amapayipi, nama-valve.
2.Isetshenziswa kakhulu kwezokundiza, i-aerospace, imboni yamakhemikhali, i-petroleum.athomu yamandla, i-semiconductor nezinye izinsimbi.
Isicelo
1.Lapho ama-perfluoroelastomers aluhlaza ehlangana nomlilo, uzokhipha i-hydrogen fluoride enobuthi kanye nenhlanganisela yezinto eziphilayo ze-fluorocarbon.
2.Ama-Perfluoroelastomers awakwazi ukuxubaniswa nempushana yensimbi efana ne-aluminium ne-magnesium powder, noma ngaphezu kwe-10% amine compound, uma lokho kwenzeka, izinga lokushisa lizovela futhi izakhi eziningana zizosabela nge-perfluoroelastomers, ezolimaza imishini nabaqhubi.
Iphakheji, Ezokuthutha kanye Nesitoreji
1.Ama-Perfluoroelastomers apakishwa ezikhwameni zepulasitiki ze-PE bese epakishwa emabhokisini ekhadibhodi.Isisindo esiphelele ngu-20Kg ibhokisi ngalinye.
2.Ama-Perfluoroelastomers ahanjiswa ngokwamakhemikhali angeyona ingozi.3.Ama-Perfluoroelastomers agcinwa endaweni yokugcina impahla eyomile nepholile, futhi kufanele aqhelelane nomthombo wokungcola, ukukhanya kwelanga namanzi ngesikhathi sokuthutha.
