Okuqukethwe kwe-FKM High Fluorine (70%)
Uchungechunge lwe-Fluoroelastomer FKM Terpolymer Gum-246 luyi-terpolymer ye-vinylidenefluoride,tetrafluoroethylene kanye ne-hexafluoropropylene.Ngenxa yokuqukethwe kwayo okuphezulu kwe-fluorine,injoloba yayo eshibhile inezindawo ezinhle kakhulu zokulwa nowoyela kanye nokuzinza okushisayo okuphezulu. isikhathi eside, ku-320℃ isikhathi esifushane.Impahla yamafutha e-antil ne-anti acid ingcono kune-FKM-26,ukumelana ne-FKM246 ku-oyela, i-ozone, imisebe, ugesi kanye ne-flamer kuyafana ne-FKM26.

Ukusetshenziswa komkhiqizo
I-FKM246 isetshenziswa kakhulu kwezezimoto, emishinini, kweye-petrochemical, nakweminye imikhakha.Isibonelo, izinto zezimpawu zendiza ezimile/ eziguquguqukayo zohlelo olusebenza ngamanzi kanye nohlelo lokuthambisa; ezisetshenziswa emishinini yokumba nasemapayipini kawoyela; imboni yamakhemikhali yemishini, ukuxhuma amapayipi aguquguqukayo, umugqa wephampu noma into evimbela ukubola, eyenziwe ngamapayipi azothwala izinyibilikisi noma enye imidiya, njengokugqwala.
Ukunaka
Irabha ye-Fluoroelastomer terpolymer inokuqina okuhle kokushisa ngaphansi kuka-200 ℃. Izokhiqiza ukubola komkhondo uma ibekwe ku-200-300'C isikhathi eside, futhi isivinini sayo sokubola sikhuphuka ngaphezu kuka-320 ℃, imikhiqizo yokubola iyi-hydrogen fluoride enobuthi. kanye ne-fluorocarbon organic compound.Lapho irabha eluhlaza ekhanyayo ihlangana nomlilo, izokhipha i-hydrogen fluoride enobuthi kanye nenhlanganisela yezinto eziphilayo ze-fluorocarbon.
I-2.FKM ayikwazi ukuxutshwa ne-metal powder efana ne-aluminium powder kanye ne-magnesium powder, noma i-amine compound engaphezu kwe-10%, 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 ehlanzekile, eyomile futhi epholile. Ithuthwa ngokwamakhemikhali angeyona ingozi, futhi kufanele iqhele emthonjeni wokungcola, ukukhanya kwelanga namanzi ngesikhathi sokuthutha.
