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 talagalay xiridda 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 kuleyl iyo koronto oo aad u wanaagsan. 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%

Waxa laga sameeyay isku dhafka adag ee PTFE (Polytetrafluoroethylene) iyo EPDM (Ethylene Propylene Diene Monomer), giraantan xidhidhiyaha waxaa loo habeeyay si ay u bixiso waxqabad aan la filayn oo deegaanka ah halkaas oo soo-gaadhis ballaaran oo warbaahin ah sida biyaha, saliidda, gaaska, saliidaha saldhigga, iyo xataa acids adag waa caqabad. Iska caabbinta kiimikada ee PTFE oo ay weheliso adkeysi sare iyo xasilloonida kulaylka ee EPDM waxay ka dhigaysaa giraanta xidhitaanka xal caalami ah, hubinta shaabad hermetic ah oo ilaalinaysa daacadnimadeeda xitaa marka la eego xaaladaha heerkulka sida caadiga ah waxay la kulmaan codsiyada warshadaha. si ay u fududaato is dhexgalka noocyo kala duwan oo ah balabaalisooyin noocyo kala duwan ah oo ay ku jiraan wafer, darafyada flange, nooca lugaha, iyo labajibbaaran fallaadhaha balanbaalista biinanka, daboolaya cabbirka dekedda oo u dhexeeya DN50 ilaa DN600. Marka laga soo tago baaxaddeeda arji ee kala duwan, badeecadani waxay soo koobaysaa u heellanaanta Sansheng ee bixinta qaybaha kor u qaadaya hufnaanta hawlgalka, badbaadada, iyo cimri dhererka nidaamyada xakamaynta dareeraha. Haddi aad ka shaqaynayso gudaha xuduuda warshadaynta dunta, la socoshada kakanaanta xarunta korantada, ama hubinta in heerarka adag ee wax soo saarka dawooyinka la buuxiyo, PTFE+EPDM Balanbaalista Valve Sealing Ring ka Sansheng Fluorine Plastics ayaa fure u ah in la gaadho habsocodka xakamaynta aan fiicnayn. iyo shaqada ugu wanagsan.
