Madow/Cagaar PTFE/FPM + EPDM Rubber Valve Kursiga Kursiga Valve Balanbaalista
PTFE + EPDM kuraasta caagga ah ee la isku daray ee ay soo saartay SML ayaa si weyn loogu isticmaalaa dharka, xarunta korantada, petrochemical, kululaynta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, birta, warshadaha iftiinka, ilaalinta deegaanka iyo meelaha kale.
Waxqabadka badeecada: caabbinta heerkulka sare, caabbinta acid wanaagsan iyo alkali iyo caabbinta saliidda; leh adkeysi soo kabasho wanaagsan leh, adag oo waara iyada oo aan dareerin.
PTFE+EPDM
Xadhkaha Teflon (PTFE) waxa uu dulsaaraa EPDM kaas oo ku xidhan giraan adag oo phenolic ah oo ku yaala wareegga kursiga ee dibadda. PTFE waxay ku fidsan tahay wejiyada kursiga iyo bannaankaba dhexroorka shaabadda flange, oo si buuxda u daboolaya lakabka elastomer-ka ee EPDM ee kursiga, kaas oo siiya adkeysi loogu xirayo afkoda waalka iyo saxanka xiran.
Xaddiga heerkulka: - 10 ° C illaa 150 ° C.
Budada PTFE (Polytetrafluoroethylene)
PTFE (Teflon) waa polymer-ka ku salaysan fluorocarbon oo caadiyan ah kan ugu adkaysiga badan kiimikaad ee balaastikada oo dhan, iyadoo ilaalinaysa sifooyin heer sare ah oo kuleyl iyo koronto ah. PTFE sidoo kale waxay leedahay iskudhaf hoose oo is jiid jiid ah sidaa darteed waxay ku habboon tahay codsiyo badan oo qulqulka hooseeya.
Walaxdani maaha -wax wasakhaysan oo ay aqbasho FDA ee codsiyada cuntada. Inkasta oo sifooyinka farsamada ee PTFE ay hooseeyaan, marka la barbardhigo balaastikada kale ee la farsameeyey, hantidoodu waxay ahaanayaan kuwo faa'iido leh oo ka badan heerkul ballaaran.
XUQUUQDA QARANKA: - 38 ° C illaa + 230 ° C.
Midabka: cad
Xadhkaha garaaca: 0%

Qalabkayaga furante-ga ee furane-ga Isku-darkan gaarka ah ee isku-darka kiimikada ee kiimikada kiimikada ee kiimikada ah ee PTFE, oo ay weheliso adkeysiga iyo adkeysiga EPDM, si loo abuuro xalka shaabadaysan oo hubiya adag, daadso oo ka soo baxa heerkulka iyo cadaadiska. Waxaa loogu talagalay in lagu waafajiyo si aan loo sal lahayn Intaa waxaa sii dheer, dhagaxaas xidhitaanka ah waxay ku aflaxaan codsiyo fara badan, laga bilaabo xaaladaha heerkulka ee saldhigyada korantada iyo dhisida peatchemical ee laga helo dawooyinka, maraakiishka, iyo warshadaha ilaalinta deegaanka, iyo kuwa kale ee ka mid ah. Awoodda quwadda ah ee keydka keydka ah ee furanteyga ah ee giraangiraha, oo ay weheliso dhismahooda adag iyo isku halaynta, waxay ka dhigeysaa qayb lagama maarmaan u ah goob kasta oo u baahan waxqabadka aan la xakamayn karin.
