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.
Heerkulka: -10°C ilaa 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.
Walaxdaani - wasakhaysan oo ay aqbashay 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.
Heerkulka: -38°C ilaa +230°C.
Midabka: cad
Xadhkaha garaaca: 0%

Waxaa laga sameeyay isku dhafka casriga ah ee PTFE (Polytetrafluoroethylene) iyo EPDM (Ethylene Propylene Diene Monomer), giraanteenna xiritaanka waxay bixisaa waxqabad aan la barbar dhigi karin oo ka dhan ah noocyo badan oo codsiyo ah. Haddi ay tahay biyaha, saliida, gaaska, saldhiga, ama xataa aashitada ugu wasakhaysan, giraantan xidhidhku waxa ay ilaalisaa daacadnimadeeda waxa ayna hubisaa in uu sugan yahay, daadin- Tilmaamaha gaarka ah ee PTFE waxay bixiyaan iska caabin gaar ah oo kiimiko ah iyo heerkul shaqo oo ballaadhan, halka EPDM ay ku darayso adkeysiga iyo adkeysiga heerkulka sare iyo xaaladaha deegaanka ee ba'an. Loogu talagalay inay si aan kala go 'lahayn ugu habboonaato nooca wafer-ka ee jilicsan ee xirxirida balaaliyeyaasha balabaalista iyo pneumatic wafer balaalista balaaliska, Alaabtayadu waxay fududaynaysaa habka rakibaadda, hubinta ku habboon cabbirka dekedaha u dhexeeya DN50 ilaa DN600. Ikhtiyaarada isku xidhka badan, oo ay ku jiraan maraqyada iyo barafyada, waxay daboolayaan baahiyaha warshadaha kala duwan, taas oo ka dhigaysa doorasho ku habboon qaybaha sida dharka, xarunta korantada, batroolka, kuleylka iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, birta, warshadaha iftiinka, iyo ilaalinta deegaanka. Qabsoo isku halaynta iyo hufnaanta Sansheng's PTFE+EPDM Balanbaalista Valve Seling Ring, oo la kulanto hawl qabad cusub oo hawlgalladaada ah.
