Zero Leakage PTFE Valve Seat Butterfly Valve Parts DN50 - DN600
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.
Mocheso oa mocheso: - 38 ° C ho ea 230 ° C.
'Mala: bosoeu

PTFE e emetse PolyTetraFluoroEthylene, e leng lentsoe la lik'hemik'hale bakeng sa polymer (CF2)n.
Polytetrafluoroethylene (PTFE) ke setho sa thermoplastic sa lelapa la fluoropolymer la polasetiki 'me se na le coefficient e tlase ea likhohlano, thepa e ntle ea ho itšireletsa.
PTFE ha e sebetse ka lik'hemik'hale ho lintho tse ngata. E boetse e khona ho mamella lits'ebetso tsa mocheso o phahameng mme e tsebahala ka thepa ea eona ea anti- stick.
Ho khetha thepa e nepahetseng ea setulo hangata ke qeto e thata ka ho fetisisa ho Balofo ea Ball Khetho. Ho thusa bareki ba rona nakong ena, re ikemiselitse ho fana ka leseli kopo ea moreki.
Litulo tsa li-valve tsa PTFE tse hlahisoang ke US li sebelisoa haholo ka masela, seteishene sa matla, petrochemical, futhumatsang le sehatsetsing, meriana, kaho ea likepe, tšepe, indasteri e bobebe, ts'ireletso ea tikoloho, indasteri ea pampiri, indasteri ea tsoekere, moea o hatelitsoeng le likarolo tse ling.
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.
