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 farsameeyay, hantideedu waxay ahaanaysaa mid faa'iido leh oo ka badan heerkul ballaaran.
XUQUUQDA QARANKA: - 38 ° C illaa + 230 ° C.
Midabka: cad
Xadhkaha garaaca: 0%
Kulaylka / Iska caabinta Qabow ee Flabbers kala duwan

Waxaa laga dhisay isku-darka adag ee PTFE (polytetrafluethylen) iyo EPDM (EthylenEnEne Propylene Diene Monomer caag), giraanta daboolan waxay dammaanad qaadaan waxqabadka aan tooska ahayn. Qeybta PTFE waxay xaqiijineysaa slick, kiimiko - dusha sare oo dusha sare ah ayaa ku habboon joogtaynta daahirka iyo kahortaga faddaraynta, gaar ahaan codsiyada nadaafadda. Waxaa taa ka duwan, ku darista EPDM waxay kor u qaadaa adkeysiga giraanta xidhitaanka ee heerkulka iyo kiimikooyinka adag, hubinta nolosha adag iyo nolosha adeegga la dheereeyey xitaa ka hooseeya xaaladaha heerkulka ah. Isku-darka nadaafadda ah ee loo yaqaan 'palve' Haddii ay tahay biyo, saliid, gaas, saliid salka, ama xitaa jawi ashyaa ah oo qalaji ah, xalkaan xiridda ayaa u kacda loolanka. Xiriirka xabaasha leh iyo kuwa Flagers, oo ay weheliso is-waafajinta oo ay la socdaan 'pneumatic alwaax' iyo luul laba laab ah Waxaa xoojisay sarajoogteeda sare
