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%

Xulashadayada oo ah fardaha xishoodka ayaa la jaan qaadaya warbaahinno fara badan, oo ay ku jiraan biyo, saliid, gaas, saliid salka, iyo xitaa walxaha amisaadka adag. Tani waxay xaqiijineysaa in, iyadoon loo eegayn warshadahaaga ama nooca gaarka ah ee warbaahintaada, shaabadaadeena ay bixin karaan adkeysiga iyo cimri dheeraynta ee lagama maarmaanka u ah hawlgalka joogtada ah. Heerkulka heerkulka ah badeecooyinkeena ayaa u adkeysan kara waa balaaran, taasoo ka dhigeysa inay ku habboon yihiin codsiyada meesha sarreysta ee heerkulka ah. Tilmaanta Sweorgengengengeng - Khadkayaga wax soo saarka - oo ay ku jiraan nooca xarkaha xargaha xargaha xargaha tuubbada jilicsan iyo tuubada publut-ka, waxay xaqiijisaa u hibeeyayadeena hal-abuurka iyo heer sare. Iyada oo ay weheliso nabarrada dekeda ee u dhexeeya DN50 illaa DN600 iyo isku xirnaanta la heli karo ee labadaba xagaf iyo darafyadeena, tuubbooyinkayaga waxaa loogu talagalay in lagu hubiyo is dhexgalka aan kala go 'lahayn ee nidaamyadaada jira. Haddii aad u baahan tahay balanbaalado jilicsan Isku-darka sare ee kuraasta madow / cagaar PTMM + EPDM + EPDM + EPDM Rank ayaa muujinaya sida aan u siino qaybaha waxqabadka sare, ee dawada, dawooyinka, ganacsiga, ilaalinta deegaanka, iyo waaxaha kale ee xasaasiga ah.
