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%

Waxaa lagu farsameeyay sare PTFE, oo caan ku ah iska caabbinta kiimikada ee kiimikada ah iyo kala-goysyada hooseeya, labo-labo ayaa si aan kala go 'lahayn uguna fiirsashada jawiga aan caadiga ahayn ee EPDM iyo iska caabbinta ee EPDM, oo abuuraya shaashad si wax ku ool ah oo si wax ku ool ah u dayactiraya biyaha, saliida, gaasaska, gaaska, iyo aashitada, iyo aashitada, iyo aashitada. Dunidan dufanka ah Giraanteena xidhmadu waxay ku habboon tahay cabirro ballaadhan oo ah cabirro balaaran, oo ah DN50 illaa DN600, taasoo ka dhigeysa codsiyo kala duwan oo ay ka mid yihiin saxaafadda oo ay ka mid yihiin xaaladaha korantada iyo dhirta korantada. Naqshadeynta ayaa diiradda ku jirta nooca xajka ee xargaha xargaha ee xargaha jilicsan ee tuubbooyinka jilicsan, oo ay ku jiraan xulashooyinka cudurka 'pneumatic alwaax alwaax', iyo nooca lugaha labajibbaarane. Shaqadani caalamiga ah ee arjigaas, waxay ku tirsanaatay qalabkeeda sare - Qalabka waxqabadka PTFE PTFE EPDM Conmpound The Weblent Trabled oo ah qayb lama huraan u ah warshadaha raadinta isku kalsooni la'aan tayada ama hufnaanta. Iyada oo ay la socoto balaastikada saboolka ee Sansshergengengence ka go'naanshaha hal-abuurka iyo cimri-galka, giraanta daahaan waxay matalaysaa kaliya wax soo saar, laakiin xalka dhameystiran ee caqabadaha warshadaha casriga ah.
