Li-gaskets tsa PTFE ke li-gaskets tse bataletseng, li-gaskets tse bōpehileng joaloka V, mehele ea piston, li-gasket tsa ball valve tse entsoeng kaLithupa tsa PTFE, Li-tubes tsa PTFE, le lipoleiti ka ho phethoha kapa ho seha ka mochini.Li na le khanyetso e ntle ea corrosion, anti-botsofali le non-conductivity.sebopeho.Kahoo, mokhoa oa ho ntlafatsa bohloeki le ho apara ho hanyetsa eaPTFE khase?
PTFE gasket ke mofuta oa thepa e manganga, e bonolo ea PTFE gasket e bonolo ho feta, e le ho eketsa ho hanyetsa ho apara, bahlahisi ba bangata ba butse mekhoa e sa tšoaneng e le li-additives bakeng sa ho fetola, ka kakaretso, ho tlatsa PTFE gasket e fetoha boitsebiso bo joalo.Lebelo la ho potoloha ha 300 ha le phahame, ha e le hantle, khohlano e tla boela e etse hore mocheso oa thepa e sa tsitsang o tsohe, ebe thepa e atoloha, e leng se etsang hore ho be le li-cylinder jams, ho theoha le ho theoha ha ts'ebetso ea ho tiisa, joalo-joalo. -seat control valve ke karolo ea ts'ebetsong ea lisebelisoa tse itekanetseng.
PTFE gasket e entsoe ka membrane ea moea, e fetang setulong se le seng se nang le valve ea fluoroplastic.Ka lebaka la ts'ebetso ea ente e phahameng ea khatello ea methapo ea li-valve, lesela le na le bokhoni ba ho hanela ho bola le ho thibela botsofali polyfluoroethylene.Ka nako e ts'oanang, e boetse e amohela PTFE gasket bellows ho tiisa, e le hore valve e ka sebelisoa lik'hemik'hale, parafine, meriana, matla a motlakase le liindasteri tse ling.Taolo ea ts'ebetso ea alkaline fluorine mahareng le likhase tse chefo le tse fetohang.
Bohlokoa ba ho ntlafatsa bohloeki ba PTFE gaskets
PTFE gasket, eo hape e tsejoang e le polytetrafluoroethylene sheath, ke gasket e seng metallic, ka kakaretso e entsoe ka likarolo tse peli, lera le koahelang le ho kenya.The cladding layer e bonts'a khanyetso ea kutu mme hangata e entsoe ka polytetrafluoroethylene.E ka etsoa ka mefuta e fapaneng ea li-gaskets tse chitja le tse rarahaneng tsa geometri.The graphite cut gasket e ka boela ea etsoa ka foromo ea sephutheloana meheleng ea ka ntle le ea ka hare, 'me e bonolo ho kenya le ho qhaqhoa' me ha ho bonolo ho e senya.Ha e bapisoa le li-plastiki tse ling, e 'nile ea sebelisoa haholo e le thepa ea ho tiisa le ea ho tlatsa, e nang le khanyetso ea lik'hemik'hale le mocheso o babatsehang oa ho hanyetsa.
Ka lebaka la bohloeki bo phahameng ba sehlahisoa, e na le khanyetso e ikhethang ea kutu, e ka amohela mocheso o phahameng le mocheso o tlase, boima bo ikhethang ba compression le matla a phahameng, e loketseng ho tiisa karolo ea khatello e tlase, hape e ka thibela kutu ea electrochemical.PTFE gasket ke thepa e tsoetseng pele e le kannete le e tloaelehileng.E na le mesebetsi e babatsehang e kang khanyetso ea creep, ho hanyetsa serame, mocheso o tlaase, ha ho na tšilafalo, ho kenya habonolo, le ho senyeha.Tlas'a preload e nyane haholo, e ka amohela khatello e kholo ea kahare le tlas'a liphetoho tsa khatello.E loketse haholo bakeng sa li-flange tsa khalase tse mahlahahlaha kapa tse tsofetseng le tse brittle, le liphetoho tsa mocheso.Re ka hlahisa li-gaskets tse hlokahalang bakeng sa basebelisi ho latela khetho ea bareki.
