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

Waxaa laga sameeyay isku-dar heer sare ah - isku darka PTFE (Polytetrafluoroethylene) iyo EPDM (Ethylene Propylene Diene Monomer), giraantan xidhidhiyaha ahi waxay wax ka qabanaysaa baahida aasaasiga ah ee shaabad adkeysi leh oo u adkeysan karta baahiyo kala duwan oo hawlgal ah. PTFE, oo caan ku ah iska caabbinta kiimikaad ee gaarka ah iyo is jiid-jiidka hooseeya, lammaane si aan macquul ahayn ula socda cimilada caanka ah ee EPDM iyo iska caabinta ozone, abuurista shaabad si wax ku ool ah u maamusha jawiga heerkulka sare iyadoo ilaalinaysa daacadnimadeeda biyaha, saliidda, gaaska, saldhigyada, iyo asiidhka. Isku-dhafkan laba-geesoodka ah wuxuu hubinayaa in hawlgalka waalka uu ahaado mid siman oo hufan, hoos u dhigaya kharashka dayactirka iyo wakhtiga hoos u dhaca si weyn. , kuwaas oo ku badan xarumaha korontada iyo dhirta petrochemical. Naqshadu waxay diiradda saartaa khadka dhexe ee jilicsan ee nooca wafer-ka ah ee shaabadeynta balabaalista, oo ay ku jiraan fursadaha loogu talagalay valves balanbaalisnimada wafer pneumatic, iyo nooca lugaha oo labajibbaaran baallayaasha balanbaalleyda aan lahayn biinanka. Caalamnimadan ku jirta codsiga, oo lagu lammaaniyo agabkeeda sare ee waxqabadka, ayaa ka dhigaysa PTFE EPDM isku-darka balastar-biyoodka xidhitaanka giraanta qayb lama huraan u ah warshadaha raadinaya isku halaynta iyada oo aan waxyeello loo geysan tayada ama hufnaanta. Iyada oo ay ka go'an tahay Sansheng Fluorine Plastics ee hal-abuurka iyo adkeysiga, giraantan xidhidhiyaha ahi ma matasho wax soo saarka oo keliya, laakiin xal dhammaystiran oo caqabadaha warshadaha casriga ah.
