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%

Giraanteena EPDM+PTFE isku-dhafan ee balaalka balaaliska ee xidhitaanka giraanta waxaa si taxadar leh loogu talagalay in lagu daboolo codsiyo kala duwan, oo u dhexeeya biyaha, saliidda, iyo gaaska, ilaa saldhigga, saliidda, iyo xitaa dhexdhexaadiyeyaasha aashitada. La qabsiga giraantan xidhidhiyaha ayaa ka dhigaysa mid ku habboon in lagu isticmaalo xaaladaha heerkulka sare, halkaas oo agabka wax lagu xidho ee dhaqanku xumaadaan. Waxaa laga heli karaa cabbirro u dhexeeya DN50 ilaa DN600, siddooyinkeena xiritaanka waxay ku habboon yihiin noocyo kala duwan oo waalka ah oo ay ku jiraan nooca wafer-ka dhexe ee jilicsan shaabadeynta balaalleyda iyo balaaliyeyaasha wafer pneumatic, hubinta ku habboon shuruudahaaga gaarka ah. Tayada aan la barbar dhigi karin ee our EPDM + PTFE isku darsan kuraasta valve ee caagga ah waxay ka yimaadaan hab wax soo saar adag, iyada oo ka faa'iidaysanaysa sayniska ugu dambeeyay si loo bixiyo badeecada aan buuxin kaliya ee ka sarraysa heerarka warshadaha. Siddooyinkan xidhidhisku waxay ka helaan isticmaalka ballaaran ee qaybaha kala duwan oo ay ka mid yihiin dunta, xarunta korontada, petrochemical, kululaynta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, biraha, warshadaha iftiinka, iyo ilaalinta deegaanka, taas oo ay ugu wacan tahay cimrigooda sare iyo dabacsanaanta hawlgalka. Haddi aad la tacaalayso heerkul sare ama walxo wasakhaysan, giraantayada wax lagu xidho waxay hubisaa in valvesyadaadu si fiican u shaqeeyaan, iyagoo yaraynaya kharashyada dayactirka iyo wakhtiga. Ku soo dhawow mustaqbalka xidhidhiyaha waalka ee Sansheng Fluorine Plastics EPDM+PTFE isku-darka balasalka valve xirmada giraanta - halkaasoo hal-abuurnimadu la kulanto kalsoonida.
