Ho feto-fetoha ha Fluoroelastomers ho Likopo tsa Likoloi
Fluoroelastomers, eo hape e tsejoang e le FKM, ke mofuta oa rabara ea maiketsetso e fanang ka mefuta-futa e ikhethang lits'ebetsong tsa likoloi. Ka motsoako oa bona o ikhethang oa ho hanyetsa mocheso o phahameng, ho lumellana le lik'hemik'hale, le ho tšoarella, li-fluoroelastomers li fetohile karolo ea bohlokoa lits'ebetsong tse fapaneng tsa likoloi.
O mong oa melemo ea mantlha ea li-fluoroelastomers ke bokhoni ba tsona ba ho mamella mocheso o feteletseng. Lisebelisoa tsena li ka sebetsa ka katleho libakeng tse tlohang ho -40 ° C ho ea ho 250 ° C, e leng se etsang hore e be tse loketseng bakeng sa lits'ebetso moo ho fetoha ha mocheso ho tloaelehileng, joalo ka litiiso tsa enjene le li-gaskets.

Ho feto-fetoha ha Fluoroelastomers ho Lisebelisoa tsa Mechini
Fluoroelastomers ke sesebelisoa se feto-fetohang haholo se fumanang lits'ebetso tse ngata liindastering tse fapaneng tsa mochini. Ka thepa ea bona e ikhethang le bokhoni ba ho mamella maemo a feteletseng, li-fluoroelastomers li fetohile tsa bohlokoa ho netefatsa ho ts'epahala le ho phela halelele ha likarolo tsa mochini.
E 'ngoe ea melemo ea bohlokoa ea li-fluoroelastomers ke ho hanyetsa ha tsona mocheso o phahameng. Lisebelisoa tsa mochini hangata li kenyelletsa ho pepesehela mocheso o phahameng, 'me li-fluoroelastomers li ka boloka thepa ea tsona ea mochini le mochesong o feteletseng.
