Setulo se Setšo / Botala PTFE/ FPM +EPDM Rubber Valve Seat for Butterfly Valve Seat
PTFE + EPDM litulo tsa li-valve tsa rabara tse entsoeng ke SML li sebelisoa haholo ka masela, seteishene sa matla, petrochemical, futhumatsang le sehatsetsing, meriana, kaho ea likepe, tšepe, indasteri e khanyang, ts'ireletso ea tikoloho le masimo a mang.
Ts'ebetso ea sehlahisoa: ho hanyetsa mocheso o phahameng, ho hanyetsa acid e ntle le alkali le ho hanyetsa oli; e nang le mamello e ntle, e tiileng le e tšoarellang ntle le ho lutla.
PTFE+ EPDM
Teflon (PTFE) liner e koahela EPDM e kopantsoeng le reng e thata ea phenolic karolong e ka ntle ea setulo. The PTFE fetela ka holim'a lifahleho litulo le outsides flange tiiso bophara, ka ho feletseng kwahela EPDM elastomer lera la setulo, e leng e fana ka ho tiea bakeng sa ho tiisa valve stems le disc e koetsoeng.
Sebaka sa mocheso: -10°C ho isa ho 150°C.
PTFE (Polytetrafluoroethylene)
PTFE (Teflon) ke polymer e thehiloeng ho fluorocarbon 'me ha e le hantle ke eona e hanyetsanang le lik'hemik'hale ho feta lipolasetiki tsohle, ha e ntse e boloka thepa e ntle ea mocheso le motlakase. PTFE e boetse e na le coefficient e tlase ea khohlano kahoo e loketse lits'ebetso tse ngata tse tlase tsa torque.
Thepa ena ha e na - e silafatsa ebile e amoheloa ke FDA bakeng sa lits'ebetso tsa lijo. Le hoja thepa ea mechine ea PTFE e tlaase, ha e bapisoa le lipolasetiki tse ling tse entsoeng ka boenjiniere, thepa ea eona e lula e le molemo ho feta mocheso o pharaletseng.
Sebaka sa mocheso: -38°C ho ea ho +230°C.
