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.
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.
Heerkulka: -38°C ilaa +230°C.
Midabka: cad
Xadhkaha garaaca: 0%

Balanbaalista furaha siddooyinkeena xiritaanka waxaa laga sameeyay isku dhafka sare ee PTFE (Polytetrafluoroethylene) iyo EPDM (Ethylene Propylene Diene Monomer), taasoo hubinaysa cimri dhererka iyo iska caabinta noocyo badan oo warbaahin adag, oo ay ku jiraan biyaha, saliidda, gaaska, saliidaha saldhigga, iyo acids. Xaruntan gaarka ah waxay ka faa'iidaysataa iska caabbinta kiimikaad ee gaarka ah ee PTFE, oo ay weheliso adkeysiga iyo dabacsanaanta EPDM, si ay u abuurto xal dabool ah oo hubiya cidhiidhi, dillaac - khadadka dhexe ee jilicsan shaabadeynta balaaliyeyaasha, oo ay ku jiraan pneumatic wafer valves balanbaalis, shaabadeenna waxay ku habboon yihiin tiro balaadhan oo ah cabbirrada waalka - laga bilaabo DN50 ilaa DN600. Intaa waxaa dheer, giraangirahan xirmooyinku waxay daboolayaan codsiyo badan, laga bilaabo xaaladaha heerkulka sare ee xarumaha tamarta iyo dhirta batroolka ilaa jawiyada baahida badan ee laga helo warshadaha dawooyinka, dhisitaanka maraakiibta, birta, iyo ilaalinta deegaanka, iyo kuwo kale. Kala-duwanaanshaha xirmooyinka xirmooyinkeena balanbaalisleyda furaha, oo ay weheliso dhismahooda adag iyo isku halaynta, waxay ka dhigaysaa qayb aan laga maarmi karin goob kasta oo u baahan waxqabadka xidhidhaynta aan liidata lahayn.
