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%

Xeerarka ayaa loo habeeyay si loo haqabtiro baahiyaha muuqaalka ballaaran ee warshadaha. Iyada oo ay weheliso scies dekeda ah ee u dhexeeya DN650 illaa DN600, oo siddooyinkeenna shaabadaysan ayaa ku filan in lagu isticmaalo wax soo saarka dharka, dhirta patrochemical, nidaamyada HVOChemical, nidaamyada 'MVOCELUTEMING', MADAXWEYNAHA, iyo inbadan. Nooca luleefanka xargaha leh ee jilicsan oo jilicsan Tani waxay xaqiijineysaa in xarunta nadaafadda EPDM + PTFE kombuyutarka balanbaaqtisadu waxay si aan kala go 'lahayn ugu dhexgali kartaa nidaamyada jira, kor u qaadida hufnaanta iyo cimri dheeraynta. Badeecadkeenna wuxuu ka gudbaa firfircoonaanta kaliya si uu u dejiyo mabaadi'da isku halaynta, hufnaanta, iyo hal-abuurka. Loogu talagalay codsiyada meesha sare - xaaladaha heerkulka ee heerkulka ah, scroring plasens pallorings 'giraan daboolan Adoo dooranaya EPDM-ka EPDM + PTFE Xarunta PtFE Blackfly Valve The Giraan, ma xulashada kaliya wax soo saar; Waxaad qaadanaysaa xalka ballan qaadaya in kor loo qaado daacadnimada hawlgalka ee nidaamyadaada, yareynta kharashaadka dayactirka, oo ay hubiyaan badbaadada iyo daahirnimada hawshaada.
