I-FKM (Copolymer)fluoroelastomer Gum-26
I-FKM copolymer Gum-26 series iyi-copolymer ye-vinylidenefluoride ne-hexafluoropropylene, okuqukethwe kwayo kwe-fluorine kungaphezu kuka-66%.Ngemva kwenqubo ye-valcanizing, imikhiqizo inokusebenza okuhle kakhulu komshini, impahla evelele yokulwa nowoyela(amafutha, uwoyela wokwenziwa, uwoyela wokugcoba)nokumelana nokushisa, engasetshenziswa emikhakheni yemboni yezimoto
Izinga lokwenziwa:Q/0321DYS005

Ukusetshenziswa komkhiqizo
Isetshenziselwa kakhulu ukukhiqiza amawasha, ama-gaskets, ama-O-rings, ama-V-ring, izigxivizo zikawoyela, ama-diaphragms, amapayipi enjoloba, amashethi ekhebula, indwangu yokushisa ukushisa, amapuleti e-valve, amalunga okunweba, amaroli enjoloba, okokunamathela kanye nezinga lokushisa legumbi lokunamathisela ezikhathini eziphikisanayo. izinga lokushisa eliphezulu, uphethiloli( uphethiloli ozenzakalelayo), uwoyela wokugcoba(uwoyela wokwenziwa), uketshezi(izinyibiliki ezihlukahlukene ezingezona ze-polar).ukugqwala(i-asidi, i-alkali),i-oxidizer eqinile(i-oleum),i-ozone, imisebe kanye nesimo sezulu.
Ukunaka
1. I-FKM inokusimama okuhle kokushisa ngaphansi kuka-200 ℃. Izodala ukubola komkhondo uma ibekwe ku-200-300℃ isikhathi eside, futhi isivinini sayo sokubola sisheshisa ngaphezu kuka-320 ℃, imikhiqizo yokubola iwubuthi ikakhulukazi i-hydrogen fluoride ne-fluorocarbon organic. uma irabha eluhlaza ehlangana nomlilo, izokhipha i-hydrogen fluoride enobuthi kanye nenhlanganisela ye-fluorocarbon orgainc.
2. I-FKM ayikwazi ukuxubaniswa nempushana yensimbi efana ne-aluminium powder kanye ne-magnesium powder, noma ngaphezu kwe-10% ye-amine compound, uma lokho kwenzeka, izinga lokushisa lizovela futhi izakhi eziningana zizosabela nge-FKM, ezolimaza imishini nabaqhubi.
Iphakheji, Ezokuthutha kanye Nesitoreji
I-1.FKM ipakishwa ezikhwameni zepulasitiki ze-PE, bese ilayishwa emakhathoni, isisindo sengqikithi yebhokisi ngalinye ngu-20kg.
I-2.FKM igcinwa endaweni yokugcina impahla ehlanzekile, eyomile futhi epholile.Ithuthwa ngokwamakhemikhali angeyona ingozi, futhi kufanele iqhele emthonjeni wokungcola, ukukhanya kwelanga namanzi ngesikhathi sokuthutha.
